RE: Modifying a really old 3m sailplane

RE: Modifying a really old 3m sailplane

After some digging in my messy garage, I found the plans - it is a Specialist V.

Spoilers sounds like a good idea. Tracy, I'd appreciate it if you could post some plans.

RE: Modifying a really old 3m sailplane

Yes, was planning on doing electric mixing. Thought maybe you meant that V-tails might not be as good as conventional (they are OK, aren't they?).

RE: Modifying a really old 3m sailplane

Wing is flat bottom, regular dihedral, slightly tapered. Aspect ratio is about 20:1. I'll try to take some pics, but may take a while. My house is being reno'd so everything is a major mess, and most...

The coro I use is a bit stiff, so I usually make an interrupted hinge to take a bit of the load off the servos (see tips on making hinges at SPADtotheBone). I usually leave at least 4 inches of coro...

RE: Motor upgrade for PT-electric
