RE: define "rock solid tail"
I can't hover for more than about 5-7 seconds without the tail drifting 90 degrees.
My servo does creep like in the Finless video until I trim it out. I've had my gyro gain
up to 100% without wag and the tail still creeps. My servo also has to be trimmed
over again after every battery change. The tail linkage is all smooth. I ordered a gy401
and a s9257. We'll see if it's better. Probably need help setting it up.
