RE: 50cc Sukhette Build Thread, now in progress!!
Sorry about the broken gear. Regarding balancing this what I do, it was posted earlier:
************************************************** ********
Mark the cg location on the flat surface that the canopy sits on.
Drill a small hole on each side of the fuselage on this flat surface
Screw a small cup hook or eyelet into each hole.
Tie a string between the two hooks.
Hang the plane by attaching a rope to the string.
Tape the canopy to the side of the fuselage in its correct location.
Put a small bubble level on the stabilizer/elevator.
Move your battery around to get the plane balanced.

I've learned a heck of a lot in the last week from our 3D pro on setting up airplanes. I've been chasing the cg all over the place, raising questions, looking for any help to get the plane to fly really decent. The guy flew the plane and recommended a few changes, specifically, reduce the up thrust, increase the aileron throw, and slow down the elevator servos. All great improvements, but it still rocked badly in an upright harrier and was real snappy regardless of where the cg was when trying to harrier. He worked on it a little more and found that I didn't have equal throw on the elevator halves. Wow what a difference!!! Now instead of fighting a poorly set up plane, I can now learn how to fly a little 3D. There still needs to be more done with the elevator linkage to get the geometry equal on both halves, but it will have to wait a few weeks. We are leaving for a two week cruise around South America tomorrow.
Happy New Year!
