like many others i did not like the idea of a micro servo running four ailerons so i used a futaba s3004,
Micro?
I just pulled out the assembly booklet. I built mine back in early 2006, and those plans didn't suggest any size servo. And the pictures weren't good enough to read the numbers on the Futabas they used.
At least a Hitec 225 Mighty Mini works great. It's not only lighter than the s3004 by 30% (.9oz versus 1.3oz) but it's stronger. The HiTec puts out 56oz-in while the Futaba does 44oz-in.
