The easiest way is to use 1/32” plywood cut out 1/4 inch larger than the oval shape that you want for the canopy. Soak it in water for 20 minutes then wrap it over the area where the canopy is to be cut out. Keep it in a low humidity area overnight. Unwrap the ply and cut it out with scissors. Cut out the canopy with a thin Dremel wheel or with a thinner diamond wheel from Harbor Freight. The plywood sill now gets epoxied to the canopy opening. Clamp with hobby clamps ( clothspins can work)

Instead of plywood fiberglass use 60 min-24 hour epoxy and fiberglass cloth. This is stronger and insures a better shape. Purchase a roll of clear Monocote or use scrap backing from a colored roll of Monocote. This material does not stick to CA or epoxy and its free usually. Cover the area of the canopy with this material and tape it in place. Lay the cloth 1 -3 once/sq yard over the clear plastic. Carefully brush the epoxy on to the cloth and roll toilet paper over the cloth to remove as much of the epoxy as possible. Don’t scrape the epoxy away as it will disturb the weave of the cloth. You can add another layer of cloth and repeat the process. When epoxy fully cures and is hard you will not have to sand the epoxy. Cut out the sill to support the canopy and epoxy in place.

Got all these projects various degrees of storage ranging from "Cold", to "Warm", to "Hot" status.

So naturally, the smart and prudent thing to do is---start ANOTHER project!

Back to the past yet Scientific Model Airplane Company's "Zipper" building notes from the Cox Engine Forum:

So, Bob's one little, though enthusiastic, comment about his fondness for Walt Musciano's 1/2A "Zipper" was just enough to push me over the edge into starting one. Went to bed thinking about it...drank coffee this morning thinking about it, so what the heck...

I built the original Scientific kit back in 1969 or so, powering it with the Babe Bee from my PT-19 QZ. A couple decades ago, I got a copy of the plan sheet, along with a nice note from the Man himself, Mr. Musciano. Been talking about building it since then.

Now, in the midst of a shop totally cluttered with tapes, dope cans, and spray equipment, I've started cutting templates from the 10% enlarged copies I made from the original plan sheet. I wanted this Zipper to be a bit larger, as I remembered the original to be better suited for a healthy .020, instead of the Babe Bee that took it around the circle like a combat wing.

Anyway, we'll see how this goes along. So far, the whole "Social Distancing" thing has turned the shop and front yard into a booming model airplane flying, dope spraying, resurrection of stalled projects, and engine test-running affair.

Everybody take care and stay healthy,
Dopey Hermit Kim

For my Windrider B737 model, I decided to design my own lights controller, mainly because most commercial kits that I found do not offer the features that I want.

Light outputs can be configured as one of the following:

- steady light

- strobe light (white LEDs in video, shifted in time for increased realism)

- rotating beacon (green LED in video)

Any light output can be triggered by an RC ppm input value, for instance:

- steady landing light can be triggered by the landing gear channel (ON when gear down)

- strobe lights can be triggered by engines on.

A first prototype of my RC aircraft lights controller is ready (see video), currently with 1W LEDs.

3W and 5W LED version will follow (parts ordered)

This is what I did to help keep the servo connection in place on this plane. It has worked really well thus far and now I am not worried about adding the new Platinum FMS 80mm 2100kv set up. take a look and hope it helps!

X440 flew great at 20.1 ounces. Started off with a power off hand toss to make sure the V tail ruddervators were set up properly. Second toss was at half power then at full power she accelerated vertically and after 5 seconds shut the motor down for glide trim. She picked up light lift and after thermaling for a few minutes tested higher speed and she did surprisingly well. If you are used to foamy motor gliders with thick wings you really get better performance on a thinner built up wing. I miss having flaps so approach and touchdown made it a little more difficult. I flew for about 5-8 minutes and only used 25 seconds of motor. The 10.5 blades draw 13 amps and 187 watts on the Turnigy Prop Drive (28-30 800 KV max amps is 20 , 1050 4S Lipo and 20 amp ESC.

On Tues July 7 I flight tested an old XP3 DHLG wing on the X440 fuselage. A hand launch proved she glided hands off with no trim needed so I used full power to climb for about 5 seconds and trimmed her out for cruise, thermal and landing modes. The Kevlar and CF wing is the thinnest of all the wings flown and the performance is so much better. I can lower the whole trailing edge about 3-5 degrees for camber thermaling and with position 2 on my DX9 D switch get real nice slow approaches and touchdowns with 45 degree down flaperons. Roll control is reduced so I have to be on top of maintaining wings level. The V tail ruddervators help out either mixed or un mixed. I’d like to put a stabilizer in...Continue Reading

DustOff #3 - King Kong/LDARC Tiny Wing 450 - Manual Mode Start to Finish ;-)


Banggood GCRC

Here is a link to the Video:

I thought this Tiny Wing would make for an excellent Micro FPV Wing ;-)
It has several flight modes; 6-axis, 3-axis, and manual.
It's made from EPP Foam which makes it extremely durable.
I think this Micro Wing has better Slow Flight Capability in Manual Mode than in Gyro Mode ;-)

Let's blow the Dust Off ;-)

Here is a free pdf ebook on how to make a self balancing vehicle. Contains details on my models, problems, resolutions, suggestions, etc.

What I have discovered with my current vehicle model:

1. Vehicle makes right turns very sharply without falling over (gyroscope rotor is spinning to the left at about 10000 rpm) but falls on sharp turns to the left. It also falls making backward right-hand turns but not backward left turns.
2. Programming requires taking into account the natural precession of the rotor and corrections must take into account which of four sectors the rotor axis is in. This is forced precession as you cannot just place the gyroscope rotor at the balance point - that will not work. It is like you have to coax the rotor into a balanced position.
3. Corrections to the gyroscope gimbal must be programmatically made in short (approximately 50 millisecond) spurts with a slight delay following to allow the gyroscope to naturally precess to a balanced point.
4. Balancing requires a gyroscope rotor of mass/total vehicle weight of anywhere from 15 to 20%. Some seem to have been successful at 8% but I think that must be because it is a full-sized vehicle and probably more efficient than at the model level. Not sure.

How can we make sharp left turns (gyro spinning to the left) without falling over and only using a single gyroscope (two gyroscopes solves this problem but has other issues). One possible solution that I have yet to try is to put the gyroscope on a 2nd gimbal and turn it when the vehicle turns (like the Gyro-X car).

Using data from 117 countries, population and IQ have an almost perfect inverse relation as seen in the correlation coefficient.
The rate of population increase is irrelevant, any increase is sufficient.

Regardless of the cause, as long as population continues to increase, IQ will decrease.
