RE: Hitec 5475's
These make great sport digitals in 60 size planes. I had tried these in a 1/4 extra running gas. Had one have a gear failure in the wing during testing on the ground. Hitec indicated that this servo's gears teeth are smaller than on the more expensive karbonite geared hitec servos. I have them in a 40 size right now with no issues whatsoever.
