Great work, Mike! Your editting in the music really makes it a good video.

I sent the link to Dave Penchuk, the current head of our IMAA District and organizer of the Giant Scale event, as I am sure he will enjoy it and may post on the Canadian IMAA web site.

Please keep up your efforts. I know that there are other  video clips hanging around on some Members' computer - all that is needed is for someone with ambition to collect a few and do the editting work to perhaps create a nice summary of some of the year's flying at our field. Adding in some still pictures works, as well.

Plans, Projects, Building and Flying Tips / Re: Coro-Junkers
« on: October 08, 2011, 06:40:28 AM »
looks like the dura-bat is going to get a lighter wing.  Thanks for posing the pics I now understand some what of how to assemble a coro- wing. Now to figure out the right win profile.   

The wing profile is self-desgning - sort of like SkyNet in miniature!

When you bend the coro over the yardstick or whatever and stick it down at the trailing edge, voila! You have your airfoil. If you are seriously considering building a wing, let me know - I may still have my little sample section kicking around that I made up for Show and Tell at one of our meetings a few years ago.

It would be great to see some more SPAD activity in our club. The local SPAD Pioneers, Gord and Dave Robertson, inspired me (they may wish to not be reminded of that, I suppose). Unfortunately, they got side-tracked by that whole electric fad - although Gord's UFO's (Unidentifiable Foamy Objects) are sort of in the same family, as technically they are made of plastic. Who knows, maybe we will get him back into the fold (little pun there?) one of these days?

Did you score any good political signs in the aftermath of the big election (see, there's another SPAD pun)?

General Discussion / Re: Fail Safe
« on: October 06, 2011, 06:56:47 PM »
To set it up properly you MUST put the IDLE TRIM to the BOTTOM then rebind it. Otherwise it will go to the idle trim position when you shut the trans off, This was the reason for the accidents you mentioned above. I found out this the hard way.


I understand what you are saying, and I agree.However, I should clarify, in my recent cases mentioned these are nitro powered, so there would be no danger of an engine start. However, the throttle was  well above max Idle trim, it was wide open. My first thought was that I had been stupid and bound it with the throttle wide open, but that was definately not the case. I am careful to make a final bind when setting up a new plane, and I check it carefully. Something had changed since that time, about 3 months ago.

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 ... ?

This ZIP has another haphazard collection of pictures, including construction photos and several Rhinebeck photos that show what inspired me to build such aircraft. There is also an old drawing that a fellow made a couple of decades ago of a Junkers that was used as a base for my development of a model.

This, second, version of my design has not flown - it has sat around for a couple of years as a spare, in case the original wore out. It has been my plan to slap a .45 2-stroke into it, tart it up a bit in some camo colours and let 'er rip. Meanwhile, the original one just keeps on truckin' and is an absolute joy to fly (and a wonder to behold!).

The big advance from the first model is the use of poly glue. No CA or other glues were used. The ability of poly to foam overcomes the issue of making coro-to-coro joints, particularly for bulkheads.

Plans, Projects, Building and Flying Tips / Coro-Junkers ZIPs - RED Original
« on: September 30, 2011, 07:12:20 AM »
Here is the collection of pics, haphazardly organized, of my original red Junkers. One could use these to build their own machine, perhaps learning something about working with coroplast along the way. The next version used a significantly easier gluing technique throughout - no CA, just polyurethane glue accelerated/foamed with window cleaner.

The basic approach can be used in building any coro aircraft. The E1 Eindecker immediately comes to mind. Peter Wagner has a (ugly!) excellent example - it flies well.

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 - some observations
« on: September 12, 2011, 05:23:03 PM »
I went to this event with the intention of picking up any bits of information that might be applicable back home, especially at the IMAA.

The location is the K-W Flying Dutchman field, which is adjacent to the K-W Rod and Gun Club just outside of St.Jacobs. It never ceases to amaze me how the whole area - Kitchener-Waterloo, Cambridge and the immediate surroundings have expanded since the "old days" when  I "got me some book larnin' " up that way. Those 3 cities now have something like 550,000 population. Then, there are the nearby towns, such as Elmira, St. Jacob, Heidelberg (I finally revisited the Heidelberg Inn, 40-some years later, for a scrumptious meal of pigtails, saurkraut and mashed potatoes - the best of German cooking!) . Not to mention Guelph and similar cities still within an hour drive.

Oh yes, there was supposed to be a point to the above ... let's see, what was it? Right - my point is that there is no comparison of the potential attendees at such an event with anything that we do in the Kingston region. Yet we have done extremely well, much better than would be expected for our region's population. And, we get no media interest (I tried to interest a couple of the Kingston media entities, but nothing came about. I did forget to contact the EMC paper that gets delivered free to our doors - must correct this next year).

 On the other hand, we probably cannot handle much more than we did for this past IMAA.

There is an admittance charge of $7 per adult for this event. That does not seem to bother anyone, as they always have a full house!  There is a lot more parking at their location than at KRCM and it appeared to be filled.

As I was arriving on Saturday morning, the first thing I saw was the giant Volksplane flying. You know, the one that came down from that area for both our FDFF and the IMAA  Their club is in New Hamburg. The builder/chief pilot/father was off fishing somewhere, but the two sons (the oldest is in Grade 12) trailered, rigged it and flew superbly. These three people are some of the nicest folks I have met in our hobby. Everyone loves that airplane - especially the little people in attendance. The latter also loved the candy drop from the giant Yardstick airplane. Talk about your mob scene - there must have been 200 yard apes, some accompanied by a mom or dad, swarming the drop zone for goodies!

The quality of the airshow's performances and the professionalism of the announcing certainly was alone worth the entrance fee, IMHO. We really should consider doing this (a short airshow with commentary) at the FDFF, I think.

 A very nice feature during the airshow was the flight by a 12-year-old who just started last year. Nothing fancy, just some solid flying with several basic aerobatics and a perfect landing.  The announcer talked about how young people can get into this hobby and follow this lad's example. Excellent promotion for MAAC and the local clubs - we need this stuff!

My estimate is that our IMAA may have had more aircraft. They said there were 150 registered pilots, while we had 106 at our IMAA, but the total number of airplanes seemed to me to be a bit greater at ours.

Next year, go and see for yourself what all the fuss is about!

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:

I think not! Some of the tumbles into the trees did remind me of things I have seen at our field - not of my doing, of course :)

Here is another one, amazing countryside, etc. Flying is not too shabby, either:
