Installed the Trio Roll Servo today. Followed Safe Air's Mount Kit's excellent instructions and pictures and it wasn't too hard at all. Discovered a part that was mislabled by Van's because of the detailed instructions. They provided everything I needed, except one screw, which was duplicated in the parts supplied by Trio. Went to Walmart and bought a small butane torch to heat up the screws on the servo, so that I could remove them and replace them with the supplied screws from Safe Air1. Highly recommend those guys. Also received my Crow 5 pt. harnesses today. They were supposed to be navy blue, but they came black. I could return them and get the blue, but I like the black. Leaves my paint schemes open too.
