Needless to say, BVM makes some of the most reliable systems on the market. I've actually fit quite a few different BVM retracts in other airplanes because I wanted gear that worked, EVERY time.

Don't forget to NOT use cheap air accessories like retract valves, tee's, brake controllers (BVM actually makes a finicky one I'm not crazy about and can leak) and fill valves.

I do a gear check before EVERY flight. EVERY time. I'm the only one I know that does this and I have had the least amount of gear failures of other people I've seen.

I test my that my gear go up and down, at least twice, EVERY time I fly. If they don't, the jet is grounded.

Let me iterate on all the air accessories that usually come with the chinese jets, your feibao included: THROW THEM ALL AWAY!
