the retracts should lock up and down on the bench,if they don't they are not set up right, I ended up using the med.servo arm that comes with futaba servo's because the small circle didn't have enough travel to get pos. lock.
the rotating gear takes some messing with to get right once you have figured it out then there easy to adjust.
before you know it you will have bent a strut, and will have to take em apart to straiten them out, or a ball joint will have blown out and will need replacing,Horizon sent me a new set when mine did.
so far my H-9 gear is holding up fairly well, but its pretty weak in general the struts will bend on just about any hard landing.
