RE: CYCLONS FOR THE MASSES!!!!
JM, sounds like you are going to do another D/F project?
Falco, you can run the APC 4.2x4 with no problem or get C/F props from Larry Driskill. I have even run cut down COX props with no trouble.....a 6x4 down to 4.2x4 and it will work great on a clean ship. For draggier applications, like free flight, they run 5.5x2 APC props. GRS models [George Cleveland] imports Russian made FAI combat planes. Larry Driskill has a great 1/2A combat plane at "kittingittogether.com" It takes very little effort to convert from control line to RC.
