When I oil the bearings that helps a little.

Could you post a picture of your c05 setup? I'm curious how you got the weight so low. Probably I'm using too much hot glue...I blame Bob for getting me addicted to the stuff.
No cogging that I can tell... starts right up every time. I wasn't really trying to get the weight low, but I soldered the motor directly to the esc, and I took off the thick heat shrink from the esc and just used packing tape for insulation. It would have weighed even less if I'd had a smaller tie wrap, haha.

i installed a bigger 7mm tail motor, different rotor blade with more pitch and the damn tail still won't hold. on top of that i have a program mix with 12% added to left rudder, it's ridiculous.. this heli doesn't make a great indoor hoverer which is what i want it for. basically hold left rudder 24/7 while hovering i hate helicopters with two motors

Hey scub, when you say it won't hold the tail are you talking about tail blow outs during pitch pumps and flips, or are you talking about the ccw tail drift? I think a 7mm will only help for blow outs, not for the ccw tail drift.

i thought it would help tail drift a little but had absolutely no effect. it gets much worse as voltage starts to drop below 3.85.

Yeah, I think it's something wrong in the rx (e.g. cheap rudder gyro, bad firmware code). If you haven't already you can read about available workarounds here http://www.helifreak.com/showthread.php?t=368255.

Dkfuji said it is NOT present in the new mini cp http://www.rcgroups.com/forums/showp...&postcount=201

Alishanmao said he would test his sample to see if it has it. I also asked Finless to check once he gets his sample from Walkera.

None of this really helps with the genius though

Will be good to get verification of no tail drift on Mini CP from different sources. For mine, putting the V3 mcpx tail on got rid of it for awhile, then it came back.

Besides that though, the tail HOLD is tremendous. Got to let mine breath outside today and was doing full speed backwards hurricanes with just a light 4mph wind and it was just rock steady. Turned them into nose down/skids in funnels and same thing. Just amazing. Add to that after 100 flights the tail boom doesn't fit so snug so it's got play in it and I slid it back a few mm.

Where did you get a 8t 1.5mm pinion? Does it hold up...not much wall thickness at the spec is there?

Edit: I see Dylan has them. I thought I looked there.

Hello, I have the c05 with zippy 400mah 20c soldered walkera ESC.
My problem is that when I try a fast flip back, tail starts spinning, loosing control.
Tail motor and blades are stock.
Do you think that walkera double brushless upgrade (obviously only tail) can fix the above situation ?
Thanks

Just finished setting up my 2801 pro for both of my Geniuses but need to check my blade pitch.

My 450 pitch gauge is far too large for the Genius.

How are you Guys checking the blade pitch? Is there something available that screws into the rotor head so that I can fit a flybar for checking against?

I used the fold the blades both back over the boom and look at them way.. I guess you could even do it this way.. Just measure the spread of the blades and figure it out for sure.

Blade length = 105 mm
1 ° 3.7 mm
2 ° 7.3 mm
3 ° 11 mm
4 ° 14.6 mm
5 ° 18.2 mm
6 ° 21.8 mm
7 ° 25.4 mm
8 ° 28.9 mm
9 ° 32.4 mm
10 ° 35.9 mm
11 ° 39.3 mm
12 ° 42.7 mm
13 ° 46 mm
14 ° 49.3 mm
15 ° 52.5 mm
l = mm

i actially have a similar app on my android phone and it actually works extremely well for setting up blade pitch...even on a micro such as the genius.

Nice find.

I presume the h parameter means the distance between both blades folded over each other at the widest point?

RC-Heli Pitch is the program on the Android market that does this. Works really well...if you have an android phone you definitely should give it a try.

Yes you just measure the distance between the blades at the tips look at the chart and you have the pitch..
