I have both mechanical and air retracts in my squadron. Both are suitable in the right situation. I would suggest a WM P-51 46. It has mechanical retracts that are fairly short and stout for the size of the plane. They come installed, so all you have to do is install the retract servo.

there is no doubt that retracts require attention, especially on a rough field or average landing technique. Try a set, either you will like them and continue to use them or not.

good luck,
Brian
