Plastic desk model that is now operational.

Brushless main motor, 6 axis gyro, 3D, CP and all on one cell to boot!

And 100.50 grams and even better, $100.00, total for this project.

Fly's well...

Very dangerous magnifying the image of the Sun without a filter, so I set my scope up with a stop-mask and got an unbelievable view of the event. Un-filtered sunlight yielded Sun spots with incredible detail. By using the projection method in conjunction with the stop-mask, things stayed cool with no heat build-up in the eyepiece and no danger for the observer.

The scope was only pointed at the Transit when actual viewing was occurring and pointed away during sighting breaks so no accidental eye damage could take place. Dancing with the Sun is always on its terms and is unforgiving of mistakes.

The pics show the Sun disk with the obvious black spot being Venus and the lesser spots being just that, Sun spots. Also a pic of the scope with the stop-mask firmly taped in place. The tiny hole is the size of a dime which furnished an image as big as a silver dollar. The two slits allowed me to open the hole even more, which increased the amount of light, resulting in a magnified image as big as a grapefruit.

The Sun set before the Transit was complete, but 80 percent of the event was viewed here on the West Coast. We followed it to the horizon.

Once in a lifetime as the next Transit is in about 105 years...see you then, boys.

Still needs control cables and wing roundels, so a full set of finished shots not far off now..

Just finished Jarel Design's that was fun...uses gear from a donor T-28 and came in at 66 grams with a WS of 20 inches.

Entire plane is either paper or cardboard...except the bungee hook, of course.

This is an old Geli kit. They had really good ink/paper and their precision in the printing shows in the final product. One of the better companies, but long gone. I've included some shots of other original unbuilt kits from Geli that I've had for years.

The paper part of the build is pretty much conventional, but the rocket tube install required some extra thought. It ended up that oval holes in the bulkheads allowed enough play for the entire length of the fuselage to be reinforced with the Estes rocket tube. This was important due to wing attachment stress and the rocket motor itself generating its stress. Also, the bungee hook had to be attached to the tube and not the paper airplane skin, for obvious reasons.

My first model was their X-15, but I ruined it during the build because my technique was flawed...should have followed the conventional method with my oval hole technique. The 105, Electra and the 106 use my modified method.

Flights were never satisfactory, but I could see that I was on the right track. With a lot more engineering in the build, mostly wing and tail fin/ele attachment, capturing the fastest scale paper airplane record would be possible. I let this project slide due to the difficulty of obtaining the proper rocket motors. Rapier style motors are the way to go, but almost impossible to find. Low thrust, long duration is the ticket. Estes motors will NOT work...too much thrust delivered much too quickly. May still make my own many projects and very little time...

Feel free to ask question...

12.5 in wingspan
23 in length
76 grams without motor/holder
1:33.3 scale

I entered this contest with a 23 year old Sig rubber job. The plane is modeled after Tom Stark's National Champ in scale rubber from 1972 &73. The real Mr M won the Bendix and Thompson Trophy in 1935 too! However, the competition in this contest is stiff, with some extraordinary efforts in the works.

After a half dozen flights or so, I must say this was a fun and worthwhile project that I would recommend trying.

It's an old Combat Models F-15 that I had stashed away for many years. It was supposed to be a 5 pound gasser that ended up being a 3 pound electro-bird. Underpowered, so a new motor is in order.
