RE: hs5975 karbonite servos
Rory
I have these on the rudders of my Intro, the carbonite gears are supposed to be four times stronger than plastic. They are agood price from Sussex Model Centre. You can get the specs from the Hitec website. Just enter "Hitec" into your browser.
You also may want to review rcguy's servo list in the Intro thread. I think the light tail servos are agood idea to save noseweight.
