I was wondering about the retract ready version, which I have. If I leave the wheel wells open (not using the plastic wheel well provided), will there be any adverse effect on flight performance? As it is, my spring air retracts don't retract completely into the wheel well, and almost half of the wheel is hanging in the breeze anyway. Which brings me to another question-can these spring air 301's be adjusted for slack? My front nose gear has quite a lot of slack when retracted, and it makes the gear hang even lower, looking like it's not fully locked in position, when in reality it is.
