Rearwin Speedster

[tommy]

I purchased a Rearwin Speedster and need information, it is from Birdi plans in the late 1970's. I need C.G.location and ail, ele, and rdr. specs. or information where to find it? All I've found is they need a motor with around 2 or 3 HP and servo trq. around 100 in.ozs. This plane had a OSMax .90 at 1.3 HP and servos at 57 in.ozs. I am changing the engine as it feels very weak and maybe is used up. The servo's are non compatible with my radio. So any help is appreciated , thanks. ph 403 526 6843.

I'm replying to myself, just to talk to someone with the same idea's. Well all the servos are in, 133 oz in. for the main controls and a 57 oz in for throttle. Motor is in an OS Max 91 FS, hooked up to a four port manifold,just like it was. Only better! All I need is a CG location and programing,then practice, for the pylon racing. Yahoo!
