DX7 & GY401

LockMD · 11-01-2008, 02:57 PM

Hey any of you guys using the DX7 with a GY401 on this bird?

Same setup on the B400, my gyro setting is set to gear using endpoints to adjust the gain my setting is 46. But on this bird I have it at 95 and still feels like it could go higher

Well, if you practice Piros and Nose in, that should help.

Finally got back in the air tonight after 4 days of no flying due to weather

Anyways, I notice a slight movement on the tail in punch outs......does that mean to lower or raise the gyro gain?

I could figure out by trial and error but I dont have much daylight to fly in the evenings anymore, so your input would be appreciated.

If the tail swings Counter Clock Wise then you may need to increase the gain. But if increasing your gain is not fixing the issuethen let me ask you this. Is your tail pitch slider able to move through the entire range of travel... i.e. from tail housing to tail hub? If not try moving your ball out one hole on your tail servo horn. If this gives you move than the full range then adjust the limit on the 401 so it does not bind. Hope this helps. You may have already done this though.

Got your reply on RCG too thanks. Will increase my gain tomorrow.

Found my magic number to be 146. Two flights lots of landings and adjustments, even took it all the way up to the max (150) and still the tail didnt wag but 146 just feels better.

Lock you Nut!!!

If you have to crank up that hard then you should really check your mechanical setup.

Something doesn't seem right.

Nah its fine.....switch over from DX6I......the 146 setting is not directly related to gyro gain.......its the endpoint setting for the gear channel on the DX7.
