Gyro Problems

[rcthrasher]

Got my 450 going again today and ive now got problems with the tail on it. It's perfect in heading hold and rate mode, but when I give it a fair bit of pitch the tail swings round one way to a certain point. When I let a bit of pitch off the tail will go back to normal but stay in that position. Anybody got any ideas on why this is now happeneing?

Gyro is a HK401B and tail servo is Hitec HSG 5084MG

You could try upping the gain a little. But tbh I never got the HK 401B to work satisfactorily. Tried everything possible, but it just never held right

In the end I gave up and fitted a used Spartan DS760, and boy, what a difference. So that would be my recommendation. Dump the HK 401B and fit a Spartan
