My new project. 860mm Weight 30g

Good work by Kimmo.

Thanks Alexey! Some more info on my model, the design is a Trivia by Gernot Bruckmann. The construction is however from carbon and mylar, no depron.

I used mostly 1.0 and 0.7mm carbon micro tubing from DPP Pultrusion, more 0.7 than 1.0mm, I did not count how much I used, but there was not much left after the build ;-) The curved carbon rods in the fuselage I made by pulling carbon tow wetted with epoxy inside some flexible tubing and taped over a pattern cut out from depron. Everything is held together with kevlar thread. The covering is 3 micron mylar supplied by Alexey, attached with 3M 77, painted first with some white car paint and Faskolor airbrush acrylics.

The motor is one of my contra-rotating units with the 10" carbon props, twin YGE-7S esc's, Spectrum AR6100 and 3x Hitec-5035 servos. The battery is a Hyperion 2S 120mAh. Since the YGE-7S does not have a BEC and the Hitec servos do not like 7.4V, I have an external BEC set to 5.5V, made by Risto (Finnspeed here in RC Groups). The flying weight with the battery is a bit below 84g.

I really like the model, the only regret is that I now know several places where to save a few grams, maybe I need to build another to get below 80g.

How did you do all the carbon to carbon gluing?

I tested one of these yesterday and they are very good. Compared to Glavak props this one behaves very much like the SG 9 x 2.8. I have not measured the pitch so I don't know which one has it correct but in the air the SG 9 x 2.3 revs much higher.

In any case the flight times and characteristics were similar to what I'm getting with the SG 9 x 2.8 in my RT Sirius Eleven. I'd say this prop works best with a light motor that has a Kv from 1500 to 1800.

My suggestions for improvements that would make these great props even better:
- a small hole in center would help in checking the balancing
- the fitment to a GWS size prop saver seems to be just a tad loose, probably less than 0.1 mm. I have not yet measured it.

Participation in the World Cup was the best event for me.
New friends and a lot of experience, helps to move the better.
I design a new plane, and you will soon see how you can make a very light model.
Now the lightest model championship from Nicolas Pietu .
