General Discussion / Innovative or what?
« on: November 25, 2011, 07:56:43 PM »
 When I first watched this, I figured that he combines some of the capabilities of two local fellows whom I know - Gord and Jeff ! I have seen some creations of these guys which really fit into the same category.

This is one awesome machine, and the video is really quite funny:

VIDEOS and PICTURES from KRCM Events and Activities / Flying in Circles
« on: November 23, 2011, 08:35:13 AM »
 I am intrigued by folks who fly in circles, or more appropriately, flying in hemispheres - real 3D stuff !

 This year, Dwayne Donnely re-joined KRCM after a multi-year rest from his CL activities and I find myself observing the action with great fascination. Lloyd Shales, a long timermaster of the art, interested Dwayne in trying CL many years ago and the bug never left him.

 Dwayne is by no means a "fair weather flyer". He is apt to show up with his lines and other gear almost any time. Recently, he and I were the only ones out at the field on a rather brisk "non-winter" day. I was enjoying a warm fire in the club house between my own flights, watching Dwayne hurl his nifty-looking biplane around.

Photographing these things is not easy, plus I was using a cheap point-an-shoot camera, so my pics do not really do justice to his activity.

 We need to get Mikey, the KRCM Official Videographer, out there someday when Dwayne or Rolly or some other CL guy is in action. I can already think of the perfect background sound track, based up on that great song, Spinning Wheel, written by David Clayton Thomas. You know, the one with that great line ... "What goes up must come down" . Just the name of the band, Blood Sweat and Tears, pretty much sums up a large part of this whole hobby that we all share!

 Anyway, here are a few of my pictures:

Plans, Projects, Building and Flying Tips / Warning about Connectors
« on: November 22, 2011, 11:30:29 AM »
 Connectors are an inherent weak link for our hobby - they can be of poor design, poor fabrication, subject to abuse and simply succumb to the stresses of their life of being pushed around, yanked upon, infused with dirt, etc.

 One of the best connector types that I see around our club these days is the Anderson Power Pole:

Many of the e-flyers use them exclusively; I (a slimer driver) use them on my chargers, power supply, electric starter, etc. Recently, I encountered a problem, or perhaps even an inherent weakness in the type. I have been using this system for my electric starter and associated battery pack. Then, two of them broke. At first, one had cracked but I continued to use it anyway. After all, this is just for a starter, it is not in an airborne power pack passing large current  and it is not going to make me crash, or burn something in my airplane.

 What I am describing is in no way a criticism of this connector type, nor would it cause me to consider using anything else.

I am attaching a picture of the 2 broken connectors, plus one which is brand new. Note that this system depends upon the plastic casing to keep the 2 spring contacts in solid contact at all times. A cracked, or even broken case on one connector will not likely matter too much (at least to me, for my starter arrangement, as I continued to use it until the second one broke off). However, if this were in a power pack for an airplane, this contact area would not be very positive, leading to high resistance and causing significant heating and voltage drop.

What I am thinking is that one should be somewhat protective of these connectors in use. Check them carefully from time to time. Those who fly electrics put many more cycles on their connectors that someone like me would.

I hope that this minor annoyance to me will result in someone checking out their systems and detecting an anomaly which could spoil their day.

General Discussion / Clear Air Turbulence, etc.
« on: November 10, 2011, 10:46:57 AM »
The loss of a senior Member's Turnbuckle the other day (it having been well strained through a pesky fence, according to reports), brought up the topic of vortices, clear air turbulence, etc. - in other words, explanations other than simple failure of the brain-to-thumbs linkage.

We know that several major airways cross our field, so perhaps this could really explain the occasional incidence of re-kitting (or, seeing as so many of the models that show up around here these days are ARF's, perhaps the better term would be re-ARFing or bARFing?), But would that really hold up? Well, here is a very good article that really explains the situation:

If we apply the basic logic principle of  Occams Razor, which states that, "given more than one possible explanation, the simplest is generally the best choice", I think that the "thumbs" still have it. (At least in my own, personal, sad experience.)

General Discussion / The pace of (rc) Progress
« on: November 07, 2011, 03:34:10 PM »

 Great comradeship, a bit of hard work, topped off with fine food and beverage - the recipe for a great day at KRCM!
The result is an amazing improvement to a large part of our field, which we really need to meet and exceed the expectations of our Members and Guests as we continue to move forward in hosting some truly world class events.

One word:     OUTSTANDING!

 On behalf of the KRCM Executive and our entire Membership, I would like to commend Rolly for planning and organizing this activity. In turn, he specifically asked me to convey his personal thanks to all who so readily pitched in to make this effort an obvious success.

There is a bit more to do, next Spring. So, those of us who missed the opportunity to contribute this time will get another chance. (I had an conflict this time, getting called away to inspect the Hoover Dam.)

While this project was ostensibly to expand and improve the camping/trailering/parking area for the IMAA Event, there is really more to it than that. Apart from providing more "people space", we have been accumulating a rather huge fuel load over many years, with our giant brush pile. Mike's rental of that giant chipper, combined with a major effort by the 17 or 18 Members (and one former, hopefully future, Member), has greatly reduced this hazard and avoided adding to the problem. Anyone want some chip for their garden? Help yourself!

Rolly passed along some photos he took on that Saturday. I have taken the liberty of selecting what looks to be a good representation of the effort. Unfortunately, no pics of the post-work chow-down, but I am told that no one was left hungry or thirsty!

If you find yourself in one of these photos, take pride. You have stepped up to the plate and provided great value to your Club. We can rent machines, buy gasoline, etc., but nothing happens without this level of volunteerism. If you participated but do not show up in any of the pictures, our apologies.

One thing that struck me - I had thought that Gord's old rock cutter / lawn mower, had been retired, but here it was again, humping trees around in a little trailer. Like an old Timex watch, it just takes a lickin' and keeps on tickin'. Someday, we may have to mount it on a post somewhere out there as an historical artifact, sort of like the Harvard at the RCAFA Club.

I noticed that Cliff, apart from being a fairly good flight Instructor, knows how to drive an ATV and haul stuff - who knew?

Apparently it took 4 guys to feed that monster chipper - four guys who were moving rather slowly the next day, as their muscles reminded them of what they had been up to!

I can hardly wait until Spring, when we  do our next clean-up. There has been a remarkable amount of work done this year, and it really shows. Next year, we will put the polish on it. Folks who have come from all over to attend one or more of our major Events are amazed at what they see when they round that last curve in the access road.

We have a great Club, we have a fantastic facility to play in, and we have FUN!

Note: There is a limitation of 12 attachments per post, so there are more pictures in the next couple of Replies.

Plans, Projects, Building and Flying Tips / SPADs over KRCM
« on: October 14, 2011, 12:47:14 PM »
I sense that there is growing enthusiasm in our Club regarding SPADs. It is heart-warming to see a classic SPA3D being launched, plus some other planes coming along.

Rather than continuing the now misleading Topic "Coro-Junkers", perhaps this is a better place to highlight what is under construction, or flying.

To whet your appetite for SPADding, here is a terrific YouTube from this year's SPADFEST:

Here is a fantastic YouTube
SPADFEST 2011 - Part 1

The Fokker D.VII in the video really caught my eye - that aircraft is a superb flyer at any size, well worth considering building. I had a .25-size Coroplast one, it was a wonderful flyer. It was one of the Combay designs popular in the SW Ontario area, particularly at the Cobble Hills Fighter Group.

General Discussion / Fail Safe
« on: October 06, 2011, 10:52:52 AM »
Once again, I have found that what I thought was OK, was not!

The other day, I noticed that when I happened to turn off my Tx before the Rx on one of my planes that the throttle sat OPEN. This has happened more than once, on different models.

The first couple of times, I assumed that it was my fault for not having properly set it when I initially set up the planes.

The time before this last incident, when I was thoroughly inspecting one of my aircraft just, I discovered that my fail safe was incorrect on  the plane I had been flying all year and which I planned to fly that weekend at the IMAA Meet! Although I know that I had set it up right, once again I had self-doubts.

Now, this last time, I absolutely know that it had been set up properly when I put this newer plane into service this summer. Yet, it was no longer OK. What has happened?

I happened to notice something regarding this in the IMAA Canada forum and I have read of other instances of similar nature in other forums.

It really seems that there is some reason to suspect that the fail safe has a problem, i.e., perhaps some subsequent change you make to the setup such as modifying sub-trims, servo travels and other parameters can mess up the fail safe. I have done all of the above on this model, at the field as I was fine tuning.

Has anyone ever obtained a definitive answer from the manufacturer - in this case I have a Spektrum DX7 and an AR700 Rx in the plane - that would state exactly what the situation is regarding permanency of the fail safe setting?

As I had mentioned to Dave Penchuk at our IMAA Meet, I believe that verifying fail safe settings should be part of the self-policed check list that IMAA requires of the pilots. I think it should be the case for any Fun Fly's, as that is where there is usually a higher risk of airplane to people contact. At least, it would be demonstrating Due Diligence, an important concept should a real problem ever occur.

With the increasing number of Electric aircraft, this seems to me to be moe of a concern. I have had many people tell me that the motor cannot start, or will shut down, if loss of Tx signal occurs. Yet, I have once witnessed a motor start in the clubhouse. I also know a person who got some pretty nasty wounds when his heli started on the bench at home - he says a faulty speed controller was the cause. So, the argument that either the Rx/Rx technology, or that of all speed controllers, insures that this cannot happen does not meet the standard.

As one of those who has lots of ideas, yet often is from the "do as I say, not as I do" camp, I really need to train myself, and encourage others, to pay attention to this potential hazard. "Thou shalt verify fail safe prior to assembling, or staging, thine airplane!". And on a related issue, let's see now, when did I last do a proper range check on my planes ... ?

VIDEOS and PICTURES from KRCM Events and Activities / NEAT Fair - Part 1
« on: September 29, 2011, 10:15:33 AM »
Now, before y'all keel over howling in laughter, this is really me talking about the NEAT Fair.

Note: Jay Kingston, when told by Rolly that Gary was coming down to NEAT, replied, "Gary who?" Rolly answered, "Gary Droppo" ...  "What the hell is he doing here?" was Jay's reaction! Well, it can now be revealed that my little trip over to the Dark Side was simply a stop-over during a larger expedition through the NE USA. (I was also trying to subtly check out the potential for "upgrading" some catchy electric flying machine to glow power, as one really has to keep abreast of what the "other camp" is up to.)

The NEAT Fair is very well organized, in a beautiful area and well worth attending by anyone. They put on a very nice demonstration airshow and there is lots of vendor and other stuff for the truly e-fflicted person to drool over, or buy. Put it on your list of things to do!

Attached are a few pictures I took, hoping to give you a sense of what it is about. Amongst these you will notice several "multi-copters" or whatever they are called. You know, those things with three, four or whatever arms tipped with motors and props and usually carryinging a stabilized video system - sometimes being flown as FPV. The one fellow in particular, who was giving a video interview, has a truly amazing setup which he designed and created.

Here is Part 1. Enjoy!

Plans, Projects, Building and Flying Tips / Coro-Junkers
« on: September 29, 2011, 07:15:33 AM »
Someone who has observed my little Junkers fly has asked for the "plans" Ooops! What plans?

Well, there sort of are some plans, after my own way of doing things. I employ two approaches - TLAR and DAYGo (That Looks About Right  and  Design As You Go, the latter being a Patent Pending sort of approach of mine). One of the features of SPADding is that you can create and save your plans right on the project itself. All you need is a magic marker and a camera, scribble the plans onto the Coro, take a picture and then start cutting.

I have 2 Junkers: the little red beauty that chugs around our field from time to time powered by a beautiful Saito 56 4-stroke, and the one which has been hanging in my shop for a couple of years but has never had radio gear and an engine (expecting to shove in a .40 or .46 someday, if/when I decide to fly it).

I took lots of construction photos during both builds, planning to someday clean them up and produce a little package in case someone else wants to use this as a base for their project. Being a staunch member of the Procrastinators Club, I never did "get around to it".

In case someone is interested, I am attaching 2 zips here. The one contains the picture set for the RED Junkers, which was my first one. The second one actually used those pictures for its build, with very few changes. The use of polyurethane glue (accelerated with window cleaner) is the main difference, that being much easier and better than CA.

FYI - you always read about "flashing" of coroplast, i.e., taking a propane torch to clean it of residual manufacturing chemicals. I never did like that idea, and I have a much better way. Use acetone. This will not harm coro, yet will take everything off and leave a perfect glue surface. I usually clean with acetone, then slightly roughen the glue region with a 3M pad, or even very fine sandpaper, and then clean again with acetone. Finally, I spritz the glue area with water or window cleaner (if I really want lots of expansion, eg., at a bulkhead to fuselage or spar to wing surface) and then apply the glue.

Important note: We have a Provincial Election campaign underway. OPPORTUNITY!!!! Stake out one of more nice big political signs and wait until the moment that the election is complete, then go and rescue your target sign from an unseemly death. That way, some poor coro-tree wasn't sacrificed in vain. You will feel MUCH better about this election season.

If you do obtain pre-used coro, take it outside, get out your cloth and acetone and have fun wiping off the printing or political mug shot that may be lurking there. It is easy, and you end up with a brand new looking sheet of building material.

I hope the 2 zips show up OK and that someone finds them useful. If you do try this, I will gladly answer any associated questions you may have. BTW, this little aircraft is a superb sport plane, will do all the tricks,  yet can fly/look like a real WW1 machine and a beginner can easily handle it. It is my own design and I am proud of it.

General Discussion / K-W Flying Dutchman Scale Rally
« on: September 12, 2011, 10:32:05 AM »
It had been 10 years since I was up to attend this event. If you have never done so, you should. The weekend is very active, yet laid back, with free flying of scale models of all sizes. It is highly organized, and runs smoothly with no dead air time and no one missing out on flying opportunities.

The Saturday air show is as good as it gets. I will mention just some of the items of note:

My friend Sandro Novelli flew Blair Hawkins' huge scale BAE Hawk - in the attached link, you cannot miss seeing it.
Sandro is quite well known in the jet world, here and in the USA. He participated in the Jet World Masters this year on Team Canada and owns at least a dozen jets. He also flies other builders' non-jet, scale aircraft, including for Graham Meares and has done so at Scale Masters. The BAE Hawk is the jet trainer for the RCAF, the RAF and apparently for the US Navy (according to the show announcer). This model, kit-built by Blair, represents something over $20K, with the engine alone being SEVEN GRAND! I took some video clips of the assembly, the carrying out of the plane to the starting circle, start-up, flying, landing, etc., and may post them here sometime.

The helicopter freestyle demo was hard to believe, set to really hard-driving music that left us stunned by the choreography alone. I had previously seen Scott Gray (I think the last name is correct) at the K-W Rally, and we brought him down to Kingston about 10 years ago to the FDFF. According to the announcer, he is ranked #2 in the world right now. He also flies full-scale Pitts.

Due to my other reason for going up to K-W this weekend, I missed the night flying. They start this at 9 pm, and Scott will do his whole helicopter performance at night!

Now, to make things even better (if that is possible), a chap from New York (I missed the name, but he is right up in the top of international competition) put on an incredible 3D routine. I believe it when some describe portions of this kind of flying as "throwing the airplane at the ground and missing". I do not know how some of this is done - my engineering education never covered the latest advances in basic physics, I guess! Who would imagine that there are servos that can act that fast? There must be a direct Vulcan mind meld or something between the pilot and the control surfaces...

In the K-W Club, there are a couple dozen fellows who do full out combat each weekend. They use the Strykers. None of that sissy ribbon cutting stuff - this is all-out, "take no prisoners" war. So, there was a demo of this swarm in the air show. It never ceases to amaze me how tough it is to DELIBERATELY perform the famous "mid-air collision" maneuver. Those of us who have lucked into such a situation never really found it to be all that skill-testing, did we?

 One participant impressed me with the way he travels. He tows this trailer - it looks like the upper half of a very large rocket - behind his motorcycle. When he arrives, he opens it and unpacks a whole squadron of aircraft, and proceeds to assembles them on the work table that is part of the trailer. Awesome!

Well, here is a link to some of the pictures already posted by others. Blair's BAE Hawk is in a couple of them:

General Discussion / Crazy Horst

Even if you don't "sprecken ze deutch", you should get the drift of this:

It would appear that this fellow is pretty well known in some circles. He has some neat videos out there.
