Plans, Projects, Building and Flying Tips / The Wonder of Drywall Tape
« on: November 19, 2017, 08:33:40 AM »
Great stuff - cheap, light, easy to work with, right up there with hot glue for usefulness in the foamology department!

I often use it to make hinges or to repair hinged or damaged areas. If you have to layer up foam or foamboard or such, this is the stuff to use. Having learned about it almost 30 years ago from Gord, I have built several large foam wings with balsa sheeting for small and large glow planes, without setting any spar material in place. Just place some strategically placed strips of drywall tape between the foam and the sheeting to distribute spar and other loading. As well, it can repair a major break in a structure. It has just enough stickum to stay in place.

The following photos show a simple way to create a multi-purpose repair tape:

1. Fasten a strip of the drywall tape to some parchment paper used for baking. That stuff is impregnated with silicone and neither melts, burns or sticks to anything.

2. Apply a light coating or some streams of hot glue to the tape.Don't overdo it, you will be spreading it out into a thin layer and if you run short, you can apply more as needed. My glue gun is an ancient, heavy duty Bostich fellow that has high heat capacity and a nicely formed tip that stays hot enough to re-melt glue.

3. Using the side of the glue gun tip, gradually spread and smooth out the glue. You want to just fill the open weave and leave a film coating across the whole thing on. If you get too aggressive, or if the glue is not hot enough, you will shift the fibreglass threads around and mess up your structure. Drywall tape is not actually woven, the threads are merely criss-crossed and lay in place due to the trace amount of stickum in them

4. Pick up your tape from its parchment paper backing. The underneath side should be shiny smooth. Cut it as desired - either knife or scissors work well.

 To apply a patch or to create a hinge, just lay the section onto the foam,  foamboard, balsa or whatever and apply heat with the side of your glue gun or, as I simetimes do, with a hotknife. (Aside: My hotknife is what looks like a  woodburning or soldering iron with a #11 Exacto blade installed. It has hundreds of hours of great use and I could not build or repair without it!) No need to add any additional glue, what is now in your tape will be sufficient to bond with the surface.

 My experience with drywall tape is that, if you make a hinge and do not have hot glue across the hinge line and/or is you have overdone the heating at the hinge line, it may break if it gets a good shock. If you have done as I suggest and have a completely coated piece, the glue film will add some strength and help to resist a shock loading.

 The final picture in this series shows a reinforcement at the elevon inner junction on a flying wing. Even on full scale aircraft, this junction is a stress riser and the designer has to ensure that it is well reinforced, typically with gussets on top and bottom or other structural features. with a flying wing, if you have an over-stress to the wing or  a hard impact to the nose, there is a high probability that a fracture would initiate at that location and the wing will fail. Been there (model aircraft only, not a real one!)

I hope this gives you some ideas for a rainy or snowy day.

FPV at KRCM / Simple Pan/Tilt System
« on: November 18, 2017, 09:34:36 AM »
Wilf and I obtained Foxeer cameras from Banggood. Wilf has used his quite a bit, mine awaits its first flight. I wanted a Pan/Tilt capability to play around with, something that was simple and cheap and compact.

I came up with the system depicted here, after some mockups in foamboard and old  hotel room plastic keys. This setup is made from thin plywood, hot glue and a patch of Velcro. I had some 5 gram servos lying around, which are ideal.

My idea is that this can simply be mounted on any of my planes, connected to a  5.8 GHz transmitter and probably with an OSD in between those two items.

As for how it can be used: On a flying wing, where there is no Rudder, that channel can be connected to the Pan servo. The Tilt servo, which is less likely to be used, can be connected to a knob or slider, or even to a 3-position switch.

On a plane which has a Rudder, there are several options for the Pan function: Use a separate channel and either control it via a knob or slider, or, mix that channel to the Rudder in whatever proportion is desired and then set up a Flight Mode to enable that function, possibly even disabling the Rudder itself during this Mode.

As for the Tilt function, if you were using a sailplane, then you could have the Throttle stick available to be mixed in to become the Tilt control, with or without the Motor enabled. I would likely do this with a Flight Mode that sets the aforementioned "Rudder" stick movement to control Pan and the "Throttle" movement for Tilt. This means that your Left stick is the camera controller while the Right stick remains as the aircraft flight controller.

If you think about it, when you fly in a real aircraft, your vision will tend to slightly lead any turn you initiate. (You do more extensive movement when performing a clearing turn prior to doing any aerobatics  or during flight in busy skies, such as thermalling in a gaggle with other sailplanes). During the resultant bank, you have already tilted this field of vision, even if you did not move your head up or down at all. At least in the case of my Mobius, with its original lens, it is already wide angle, so unless I wished to look back over the tail, I probably need very little movement in either the Pan or Tilt plane. What I can envision the Tilt  for is to perhaps have a fixed, slightly downward, setting that would be useful while setting up an approach - or possibly to help figure out where I am if I am FPVing and get lost!

Plans, Projects, Building and Flying Tips / The Power of Magnetism!
« on: November 16, 2017, 07:04:06 AM »
Do you, like me, get tired of hunting for that bolt, nut or other small metal item that you just removed from something and which jumped off the bench? Or worse still, it fell into the grass or dirt at the field and, of course, it is like no other one that you have immediately available!

I have a collection of the small rare earth magnets in different sizes, which I got at Princess Auto for a pittance. They have many uses, including canopy retention on airplanes, etc. Here is another:

 Either on a temporary or permanent basis, I stick them onto one or more of my commonly used screwdrivers and sometimes on some other metal tool or object. That way, when I am removing a screw, I just let it stick to the magnet on the tool until needed.  Depending upon the task at hand, my screwdriver looks like it has a swarm of bees clinging to it by the time everything is ripped apart. No more crawling around on the floor or the grass looking for an escapee!

VIDEOS and PICTURES from KRCM Events and Activities / Microwing
« on: October 28, 2017, 09:05:27 AM »
 This little mashup shows some test fights of Gary's MicroWing. This cool little machine costs next to nothing in time, effort or cash  to build and flies exceptionally well. Within this video are a couple of demos of my (original idea?) lawn chair launch technique. (I am working on doing lawn chair landings in the near future, hopefully of the non-destructive kind. Please stay tuned!)
 I am building another one at this time, because ... ? Who needs an excuse, when you are having fun, eh!

 Thanks again to Wilf and Harold for the video assistance.

General Discussion / Puddle Flying
« on: October 23, 2017, 07:22:08 AM »
I have a rather large puddle to fly from, Lake Ontario! If you are not as fortunate, do not give up, there is still hope. I found this little video to be rather fun and uplifting. Enjoy!

General Discussion / Huckoween - summary, etc.
« on: October 19, 2017, 08:31:47 AM »
 We had an outstanding first ever Huckoween this past Saturday. I will attempt to summarize some aspects of it.

 First of all, this was a significant, well attended event which had NO outlay of KRCM effort or financial risks involved. All we had to do was to issue an invite and lay out the welcome mat. No mess to clean up afterward, the only things left behind were a lot of great memories. The ideal fun fly?

There were 22 pilots registered, with just about all of them showing up despite the questionable weather prognosis. For many of them, ths involved a 6+ hour drive each way with airplane trailer in tow. Was it worth it? Of course it was!

 Some thanks are in order:

 Brad organized things, setting up the invite over at   
where you can catch up on the whole affair, including the videos which have been trickling in.
 Our Grounds Maintenance crew went to extra efforts to have this wonderful facility in the best possible shape. The grass was manicured, the clubhouse was all cleaned up (yay, Thomas!) and it was a place to be proud of. Our guests were impressed! Thank you, Marvin and Thomas.
  Food is important. Anyone who wanted some just had to throw in $5 and expect to rip off a couple of hunks of pizza, hand delivered from Capri Pizza in Amherstview, courtesy of Terry and Marilyn. Thank you, folks!
 Brad initiated a 50/50 draw and, as I enjoy pestering people and begging for money, I set out to scoop up some coin for the cause. These folks really do like to support any club which welcomes them, as the results showed. Tickets were $5 each, 4 for $15 or 5 for $20 (I had to talk fast so that the customer didn't have time to do the math of that latter part of that "deal"). When the dust settled, the winner (Mike "it only takes one ticket to win" Siemonsen) took home $195 or thereabouts, with the same amount being turned over to KRCM. Thank you to all who participated.

 The only expense incurred was to pump out the Portapottie, something that would have to be done this fall anyway. Thanks, Rolly, for thinking to get this done.

 There was a lot of remarkable flying done on Saturday in rather fine weather. None of this prevented anyone in our Club from flying, if they cared to. I flew some of my small stuff over at the side several times. The little Kwirl autogyro attracted some significant attention - sort of at the opposite end of modelling from the big stuff featured. I had hoped that the Halloween witch, Bubba or something else from the Flypaper collection would have would show up - perhaps next year?

 From what I have heard, these folks would love to come back again - either for another Huckoween or perhaps at some other time. A bit earlier in the Fall, say, late September might be better timing, or perhaps next Spring? Our field is open year round, the weather is usually good and predictable by April and it is a long stretch from that time until our Fathers Day Fun Fly occurs. Lots of opportunities!

 At the KRCM Meeting this week, great interest was expressed in doing this again!

Plans, Projects, Building and Flying Tips / Steaming Dents Out Of Foam
« on: October 04, 2017, 08:08:35 AM »
This is a technique which I have been using. I even thought that I had invented it! On several recent occasions, I heard folks asking for advice about this.
I came across this write-up, with pictures, and thought that it would be useful to post here:


 In cases where there is some major damage, say, near the leading edge of a glider wing, you may not be able to completely heal it using this technique. You may even have had to splice in a chunk of foam and then try to conform the repair to desired shape. I had to do such a repair on a large foam sailplane canopy after it popped off and encountered the prop on its way out.

 Light spackling compound is your friend! It weighs very little, can be  thinned with water as needed, applied in layers and easily sanded. Give it lots of time to thoroughly dry, don't try to build up huge globs as once, especially if you have mixed any water in. Overnight is a perfect cure time. After sanding, you can paint over it, and the surrounding area, if you wish. My canopy was a real mess, but after repairing and painting (several coats of brushed on water-based acrylic craft paint), it is very hard to tell that it was ever damaged.

General Discussion / Inside a Drone Factory

Another great item posted on the FLITETEST forum. This also gives a great insight into what one of China's great cities and manufacturing hubs is like - not really what many folks imagine.

This will pull together and replace a couple of items which may be of help to someone trying to figure out how to post their product.

Lost And Found / Introduction to Lost and Found
« on: September 07, 2017, 10:57:48 AM »
Please post a description of the item(s) in here.

In the case of a lost aircraft, tell us what kind and colour the plane was and  try to describe landmarks which may enable someone else to track it down.

For example:
"Standing at the Clubhouse door, look toward the second Flight Station. I think the plane may be a long way out, past the first tree line. We saw it go down".

OR, perhaps:

 "Joe X. saw it go down from where he was standing." (That way ,Joe can point out to others more specifically what he saw).

This is a new but widely used and well respected Transmitter targetted for multi-rotors. I bought it as an experiment to see if it would work on airplanes. It did the basic job but lacked certain features that I require. (It looks like there are some Open Source efforts underway to modify it for more general purpose use, but no updates yet.)

- Evolution Transmitter, with originally included Receiver
 - 2 additional receivers
 Original value, over 100$CDN.
 Make a reasonable offer!

General Discussion / 2017 Record ClusterHuck
« on: August 28, 2017, 05:48:12 AM »
Lots of posts surrounding the HuckFest this past weekend! In here is the video of the ClusterHuck - new record, 14 in the cluster! KRCM was well represented by Brad, see if you can spot his plane in there ...

Wouldn't it be fun if we could entice the group to come down here some weekend? Folks would be able to see and learn about top notch 3D and regular sport flying, as well as the intricacies of the most advanced technology in our sport from some of the best in the field.
