help with 250fbl
I've the spectrum AR7200 FBL on my pimped 250 heli today, i had my 250 out & i have a couple of problems. first thing i noticed was when hovering is no problem, but as soon as i fly slightly forward & then fly backwards the head whips around to the right & i have to correct with left rudder stick.
I'm not sure whats causing this & i've done a couple of flips no problem but the heli feels a bit shaky when flips are used i'm not sure what to do...

In my experience on other FBL helis what you describe is from too much cyclic gyro gain. The cyclic gyros are trying to fight you. Try a little lower cyclic gyro gain to see if that effect starts minimizing.
Good Luck, Don |
