RE: Ultra RC 92
I assume this is the same kit we purchased thru Troybuilt, as parts layout etc looks just like ours. Never checked the incidences but the zero is a dream to fly as designed once properly balanced.
Only negative I had on the kit was the very weak wood used for retract rails and poor design on tail wheel retract unit. I replaced with a better hardwood and stronger glue joints. Standard Robart retract tail wheel was a easy replacement using same mount.
