Here is an excellent NASA document which I found in another forum. If you find it too lengthy or difficult to understand, just enjoy the pretty pictures!

Upcoming Events at KRCM and elsewhere / 2019 KRCM Auction - February 16
« on: January 06, 2019, 11:06:58 AM »
The Annual KRCM Auction is Saturday, Feb.16, at the RCAFA Club at Kingston Airport, where the Harvard is mounted.
The doors will be open at 0900 hours, to allow for set-ups and registration.

Clear out those Hangar Queens. If you haven't flown them for months or years, you don't need them. Dig out and dust off that old kit that you're never "gonna get around to" building. Tools, engines, radio gear - it's all welcome. Turn this into cash, then buy someone else's stuff.

Plan to get there in good time, register (FREE, of course!), set up your stuff on a table (no charge)and relax. The Club receives a 10% commission on all sales.

Make use of the RCAFA bar for soft drinks and other libations, popcorn, tater chips, etc. Bring your own sandwich, the action is non-stop!

Throw a buck or two into the 50/50 draw - you may become a very RICH person. We give the other half to the RCAFA, as they waive the usual rental fee for this day.

Browse around, check out the wares, meet others, and get ready for the main event.

Then, the fun really begins We have a highly experienced Auction Team eager to spring into action. Keep them busy, make them happy:

* The Auction itself will get underway as soon as Registration is completed, planning for 1030 hours.

* The 50/50 draw will take place around noon.

* Our Auction System allows Participants to settle up at any time, in case you have to leave early.

* We expect to wrap things up by mid-afternoon.

Fortunately, we haven't had one of these arrive at the Toyground in a long, long time!

Did someone say there was a Flypaper Foamy Challenge underway? (Reg?)

A decade or more ago, my friend Gord. a.k.a. Flypaper, built an electric Pogo. It flew well but never did achieve vertical landing. I was nevertheless impressed and so I built a larger one of Coroplast, powered by a .30 or so glow engine. Like Gord's, it flew well but mine had no hope of even standing vertically long enough to take off nicely, due to engine vibration and inadequate engine acceleration compared to an electric system. Over the years, Gord produced one or two more electric Pogos, one of which even folded up for transport in the Flypaper Express. I think that Dwayne obtained the last one. Gord was quite successful in takeoffs and I witnessed the occasional vertical landing as well,

So, time marches on (too fast, it seems).

Too much idle time plus some uncommitted hardware and a new source of exceedingly cheap Depron means- what to do?
Well, a Pogo wannabe emerged and off we go to the Toyground where Dwayne was lurking beside the nice warm stove, ready to video my attempts at miniature aviation. Here is the result:

At this time, the Pogo has been revamped a bit, some lessons have been learned and we shall try again in a day or two. As for the Vertical part of VTOL, well the TO part is promising but the odds are stacked against the L part. But, we shall see ...

The Flypaper Challenge is well under way. Reg now has a considerable lead. Here is the evidence!

He has to stop building WHITE flying objects for winter flying, it makes it too difficult for us to enjoy the full viewing experience. Oh well, the poor
fellow has a good time - as you can see here.

Buy, Sell, Trade or Give Away / Hobby King Order?
« on: December 16, 2018, 08:44:56 AM »
Any of you folks planning to place a Hobby King order?

If so, I would appreciate adding in a dozen or so servo repair kits.

I repair any HXT900, HXT500 servos, as well as various HiTec, etc., which suffer broken gears.

Why? Because I am a cheapskate, it is a 5 minute effort which I enjoy and the result is a better than new (little trade secret there) servo.
A gearset costs about $1 - still cheaper than spending a whole $3 or $4 for a new servo.

Meanwhile, don't throw out your broken servos, I will take them off your hands. In fact, if it is just stripped gear(s) and you supply or pay for the required gearset, I will rebuild it for you and apply my world famous "tail light warrantee" coverage.

General Discussion / Warning - electrical issue!
« on: December 16, 2018, 08:17:17 AM »
Recently, I "repackaged" my Optera (reminder to self, when you take your eyes off a white wing at high altitude, even for a couple of seconds, you may not be able to re-acquire said flying object!).

When I was removing the hardware, guess what I noticed at the spinning end! (Photo attached)

This particular situation could exist on any installation but may be difficult to detect. In the case of my Optera, which was 2 or 3 years old and well used, the leads from the motor must have been jammed into place at the time of assembly. One of the three was rubbing against the rotor, resulting in the wearing away of the blue anodizing and, more importantly, the insulation and underlying wire, being worn down.

Now, this poor installation could just as well have worn down more than one of the three wires. Had that been the case, something bad would have happened. In the worst case, fire! In the not so bad case, the ESC and structure itself would have been demolished. LiPo fire, anyone?

Although this was a factory installation, buried well within the aircraft's structure and impossible to see without major disassembly, it could happen with other setups.

One lesson that I have learned is to carefully inspect any initial installation prior to first flight - if at all possible. You are usually dealing with a very high energy density system.

General Discussion / Apace - the final frontier
« on: December 13, 2018, 12:08:12 PM »
It's getting closer, at least for those who have some serious coin. Here is the latest development, where SpaceShip 1 officially reached space (non- orbital ,of course, but pretty good anyway!). The accompanying video is excellent, you get to see inside the hangar, in flight, etc. Enjoy!

Wouldn't it be a nice group project to build a model of the mother ship and the space plane? We could pretend that "outer space" starts just a half dozen trees high, right? Awhile back, Andy Kunz of Spektrum fame, built an r/c replica of one of the NASA lifting bodies. Although not all that great in flight, it was a really cool project.

General Discussion / Flying the big jets - from a test pilot's viewpoint
« on: December 07, 2018, 09:13:15 AM »
For anyone who is interested in big aviation, test and certification flying as seen through the eyes of the best, here is something to enjoy. The podcasts are long but certainly not boring! I download them onto a thumb drive, phone, tablet, etc., to enjoy while waiting for an appointment or while puttering in the shop.

“The test pilots’ test pilot”, former CAA Chief Test Pilot D. P. Davies talks about his early career first training and then serving in the wartime Fleet Air Arm, including reminiscences of the naval test pilots course, the Empire Central Flying School at Hullavington and the Handling Squadron. He recounts flying the Fairey Swordfish, Fairey Barracuda, Blackburn Firebrand, Grumman Avenger, Hawker Sea Fury and Supermarine Seafire. During the post-war era, he was "the man" whose word was the ultimate in accepting new aircraft into British service.

I bought his book
Handling the Big Jets:
An Explanation of the Significant Difference in Flying Qualities Between Jet Transport Aeroplanes and Piston Engined Transports

way back in 1973, as a byproduct of interviewing for a job at the NRC's National Aeronautical Establishment.

Although directed toward air transport pilots, it is quite readable for others and remains an extremely popular book amongst the originally intended audience. It is still available through Amazon. I could never have imagined that, 6 years later I would have a future air transport pilot and production Dantest pilot in my family. He found this book to be very useful in his flying career. The down side is that some of his cohorts have also found MY copy to be useful and I am having a difficult time reeling it back into my collection!

VIDEOS and PICTURES from KRCM Events and Activities / Mutley

I have been an ardent fan of Dick Dastardly and his dawg, Mutley, for many decades (Growing old is manditory; growing up is optional. I rest my case.).

So, several years ago, I created this little monstrosity. It flew well, much better than it appears on this particular day in the howling wind. The cartoon world offers a lot of ideas to those of us who seek out new frontiers.

FPV at KRCM / Skipp(er)ing Around The Bay
« on: November 21, 2018, 06:48:42 PM »
Here is another little video that I cobbled together. It features that wonderful little all-terrain, all-season, all-weather flying machine from HK , the Skipper. Roger has the same model, which he purchased from Great Planes - they call it the Dragonfly. This flight took place back in "pre-windmill" times out here on the rock.

I have flown the Mobius on it but have not yet done full FPV. That may happen as soon as this weekend, as it is one of my "winter" planes. I only have to clip the Mobius into its 5.8 GHz transmitter case and pop it onto the plane. My reason for not trying full FPV already is that I have lacked confidence. Although Skipper has NO bad flight characteristics and can be slowed down very nicely, it may still be more of a challenge than the Fun Cub or Penguin for a low time FPV pilot like me. As well, the spotter may have difficulty in keeping track of it due to its smaller size, minimum profile and ability to cover a lot of territory rather quickly. We shall see ...

 Meanwhile, here is the video. The aerial portion seems rather jerky; perhaps, I had the stabilizer Gain a bit too high or perhaps I had the stabilizer turned Off, I cannot remember.

VIDEOS and PICTURES from KRCM Events and Activities / Muddy Red Baron
« on: November 18, 2018, 09:26:02 AM »
 I have been sorting out a ragtag collection of video clips and trying to make something out of them.

 Well, here is one that brings back some fond memories. It is hard to realize that Gordy has been gone a whole year now. His "Muddy Red Baron" speaks a lot about him. I reckon that assemblage of airborne material logged more air time than anything else at our field, over a period of several years and many reincarnations. Wings, struts, cowl, tailfeathers, fuselage - they all saw a lot of hot glue and/or were swapped out for "enhanced" versions. The guy got more fun out of flying than anyone I have ever known, and this particular craft was perhaps his most prized toy!

So, without further delay, here is The One And Only MUDDY RED BARON!

FPV at KRCM / Opterra FPV - March 2017
« on: November 16, 2018, 11:01:02 AM »
I discovered some mislaid video clips where I had popped the Mobius into its 5.8 GHz vtx and stuck it on the Opterra. Here is the cobbled together video that resulted. No music (too bad), no commentary by me (perhaps a good thing?).

General Discussion / Real Float Flying
« on: November 13, 2018, 07:01:05 PM »
 I made the following video for family viewing but some of you KRCM folks know the Pilot and First Officer. The actual takeoff occurs around the 3 minute mark and it is rather impressive to see from my vantage point. In case you wonder what the Pilot is doing wandering around on the floats: part of the pre-flight after extended water time is to check and, if necessary, pump out the float compartments - there is always some condensation and/or minor leakage and you don't need to be carrying an extra couple hundred pounds around. (That was my job when I flew with him; Miky was not yet trained up on that.)

At the time this video was shot, Dan had a minority partnership in the airplane. His client, a financier for whom Dan flew the Gulfstream business jet, acquired the plane and Dan flew it for him. Most of the routine flying was between Billy Bishop Toronto City Airport ( YTZ ) and the client's summer "cottage" up in the Muskokas - a one hour flight vs. 5 or more by car.

Dan used to fly into our bay, where I had the temporary mooring, sometimes staying for a day or two, usually accompanied by his First Officer. Mikayla. This usually involved a 20 minute hop from Buttonville, where the plane was hangered, over to St. Catherines to pick up Miky and then about an hour and a quarter down to our place. She had her own Log Book and did some of the flying, including gentle turns and other fancy stuff!

 This is a Cessna 206, often referred to as an "all terrain" aircraft. These are widely used as a bush plane, skydiving jump plane, and personal transport plane. It seats six, has double doors for passenger or cargo handling and is very comfortable.

This plane has very modern instrumentation, including autopilot. Its 310+ horsepower engine and the Wipline amphibian floats equip it well for zipping in and out of confined areas. Dan installed the STOL kit, consisting of a large number of vortex generators on the wing upper surface and under surface of the horizontal stabilizer, which significantly lower the stall speed and thus enable better takeoff and load carrying capability.
