RE: Electric Retracts - Modifying existing Air/Servo-operated Retracts
I found a set of Robart's at the local hobby shop for the TF giant P-51, in the clearance bin, marked down so low I couldnt pass them up. Shortened the strut, switched a few things around, and vwella! they worked! surprisingly very minimal modification. I ended up saving $190.00 Cant beat that!
Unfortunatly, the way the wing/spar plug ins are designed and the retracts taking up some room, I cant get the reqired space for an internal bellcrank or nyrod pushrods, w/ out drilling thru the spar/spar pockets.
In this case, linear is the best way to go, as i do have approx 7"x2" space between wing ribs on either side of the flaps. The L12'$ will fit, but hey, I got a kid to put thru school !
I ordered a L12 and some gearmotors to play with, I just need a source for micro limit switches (i only need three settings), adapters (send me the link to the ones you found,- i got taps) and some other micro hardware. The chasis platform, flap track, and leadnut horn i'll have machined out of aluminum. (thank god for buddies).
For your thrust bearing issue, I'd try the RC car guys, they got allot of small parts!
