Ok campers, with a lot of help from Ink and some trial and error I have my new toy flying pretty damn good. I haven't really started to get after it much but it certainly is the most powerful heli I have flown to date.





So here we go...

I still have a tail drift. It is very slight but certainly noticeable. I have the cyclics trimmed out very well and I will be happy with a little more tweaking. I am running 1950HS and the engine is still on the rich side but breaking in nicely. At this HS the nose will drive to the right. When I slow the HS to 1800 the drift is slower but it is the opposite direction. I have adjusted the common gain up to 100 and the drift is still about the same.

Should I set up my gov to run the same HS in idle 1 and 2? Then use the trim buttons to get the tail to hold still?

How do the P, I, and D gains effect the heli? At what point to I try to adjust them to get the desired tail performance?

Lou, great work!

Vbar Tail/Rudder config: What's your current "Gyro deadband"? Try to reduce that to 1 or even 0. It may result in some drifting while still on ground but it may help in the air...

How far apart should the balls on the blade grips on a 90 size be?

I think Makido 50 heads measure 32mm from center of main shaft
to ball on blade grip. You would think the distance should be
greater for a 90 size.
Thanks,
Roy
