RE: GSP hellcat????????
Retracts for the GSP hellcat are a problem. Robart 615 do not fit .Century Jet made me a set of mechanical retracts but they would not stay locked up or down without air pressure (They should have known this). They next remodified them for air but now the air nipple was in wrong location for this arirplane and they wouldn't slide in to place. Sent them back again andthey are moving the nipple--they understand the problem. Should work now-i'll get them back(3rd time!) tomorrow. Be careful when you enlarge the hole through the spar to accomodate the air cylinder. If you remove too much the wing may fail. DO NOT cut away the spar.
