It's the amount of movement in degrees the gear moves from fully up to fully down. What does that mean? Whats the difference between between the 90 and the 85? (besides one being 5 degrees more than the other!) Is it that the struts iin the 85 degree ones are ''bent in'' 5 degrees more in the locked position whereas the 90 degree ones are straight (90 degrees to the wing) in the down position ? įor instance in the first post John wrote :Ĩ5° main units for you P-51, P-47 guys out there'' I'm new to retracts and am somewhat cinfused as to what the various types ''in degrees'' mean. The mechanism might be a little light for a 10-12 pound airplane though, you'll want to make sure the gear lock down before you land. Overall they look pretty good for the money, I'm glad I got them. I might try to find a way to support the motor wires better before I use them. But it looks like it's there for insulation of the solder joint and not stress relief, so the wire might be prone to breaking there over time. Where the motor wires are attached they're potted with some RTV. I think this all means that you'll have to make sure your gear doesn't bind on anything and definitely make sure they're locked down before you land. Also, since the brass pin hits a limit switch, it doesn't let the pin seat all the way to the end of the W cutout. The jack screw is a little light too, looks to be the size of a 4-40 screw. I was surprised that the brass slider hits limit switches to shut off, so I'm wondering if that means it doesn't have a current limit shut off. The trunion looks typical size, but the brass slider pin looks to be a bit thinner than most retracts, but I didn't measure it. The side rails are machined out of 3/32 angle stock and look strong enough.

The trunion is brass bushed with no wobble.
