Flying Bud has just about finished his RB.. The only thing that looks major is the down thrust of the engine.He put it together according to instructions but the down thrust looks excessive.The cowl fits up against the fuse indention like it should but with the engine in place it's got a bad down/droop which is certainly noticeable. The spinner backplate isn't even close to the center of the cowl opening and the distance from the front of the cowl to the spinner backplate is much more on the top than the bottom..This looks like crud and seems to be excessive. This causes the plane to look bad.
Is yalls like that? What did you do? I told him I would shim the engine mount on the bottom and try to lift the engine up.Maybe looking a little better.He's running a Saito 1.50.I think too much power but that's what he wanted to do.
Thanx for the help

Q-Ball,
I would recommend you read the entire thread on the RB. There are some important factory issues that need to be corrected during assembly. These guys have done an excellent job of reporting on these as well as developing the fixes.
The major problems are in the retract mounts tearing out in the wings, the horizontal stab breaking and also the excessive downthrust. There is speculation that the downthrust may even cause or at least contribute to the stab failures if I recall.

Good luck with your Bear.
