Thanx everyone! I have the Hot Knife profile and with these servos (5 HS-81), a 5C NiMh 300mah 2/3 AAA, the HS-555 receiver, powered by the Mag. XLS 52 using a 6oz. fuel tank, the plane weighs in at just a hair under 3Lbs.! The 6v runs the servos a bit faster and the torque at 42oz.!

I did look at the 255's but I'm really am looking to go light---possibly changing to metal gears sounds good. I did hook up a Cirrus 4.9 servo to the throttle and it worked fine (in test-grounded), but am not sure to trust it though it does have a pound of torque.

Thanx again
