Default Cryodrive shaft length flight testing

I started a new thread because I'm not too impressed with how my original thread turned out, it leaves a bad taste in my mouth.

Anyhoo, I went with setup 15mm longer then stock, I'm using Microheli Al swash and Microheli Al lower hub, E-flite Al upper hub and cf flybar with Xtreme Al center.

With such a large gap between the rotors, the heli is less stable, as it should be. I added another collar to each side of the flybar (4 per side) so now the flybar is only .75g lighter than stock. That helped.

As for fast forward flight, it is improved, I'll have to test it better when its not dark out (flying using the street lights is a bit tricky).

Tomorrow I'll put the servo arms on the 3rd notch (they were on the 1st one for the earlier flights) as I felt I could use more pitch (controlling thrust) to help counteract winds.

But my gut feeling is that I don't need such a large gap between rotors for my specific setup. I'll try moving the servo arms way out just to see what kinda pitch I can get, but I'm thinking there's only so much this heli can do, its not a high performance heli after all. If with the servo arms at the last hole and I still get no clack, then I'll reduce the gap to 10mm and see how that works, the heli will be more stable with the 10mm gap, as others have said.

One this I have noticed is that the heli really gets blown around in the wind. Its got nothing to do with the amount of pitch (controlling thrust) it can produce, its just very light; the added thrust will allow you to recovery from the wind, but you'll still get pushed around regardless.

One thing I like is how I can cut the throttle from 6' in the air and the heli drops without damage - no way I could do that with my TREX... the CX2 is so light, as long as you cut throttle, it bounces more then it breaks.
