h@h racing:

I will put a second on the Hitec HS-225BB servos. I have quite a few in service, very pleased.

They are equivalent to "Standard" sevos in power, and are both smaller and lighter.

But I'll disagree with JWN - metal gears are to be avoided. THey wear and get sloppy, and in a crash I'd rather buy a cheap gearset than have to repair/replace something more expensive.
