sjcrash,
You stated
I do not agree that Rare Bear is a good buy. I had one and the stabs blew out on the second flight at part throttle, using a ys91 with a 14x10 prop.
You obviously didn't read the LAST SENTENCE of my post.
They would have a winner on their hands if they fixed the problem areas.
I still stand by this statement. I've flown mine several times at full throttle going downhill and I haven't had a single problem. However I have made modifications to correct the deficiencies identified by others that haven't been as fortunate with their RBs.
To recap the mods.
1) Installed blocking in the horz. stabs and elevators for Robart Hinge Points.
2) Opened the stab skins and reglued ever joint.
3)Ensured that the fiberglass tube spars where properly fitted and then glued to each rib it penetracted with 2hr epoxy and BVM mill fibre mix.
4)Gap sealed the elevator hinge lines.
5) Tossed all the elevator hardware and utilized high quality parts with 4-40 threads
6) Doubled the thickness of the rudder post inside the vert stab. Installed blocking in the rudder for large hinge points.
7) Utilized the large Robart Hinge Points for the rudder.
8)Installed redesigned and proper retract mounts constructed from 1/4" 5-ply plywood.
9)Removed the front former, cleaned up interior of fuselage and the former, reglued front former into the fuselage with industrial grade epoxy (12 hour set) mixed will BVM mill fibre.
10)Decreased the downthrust and right thrust by approximately 1 degree each.
11) Threw away all the aileron hardware and replaced with quality US manufactured components.
12) Replaced the aileron hinges with Radio South Giant Scale CA Hinges.
I'm running an ASP 1.08 Redhead with Bisson Pitts muffler, turning a 14 x7 Master Airscrew 3-blade. Level flight speed is in excess of 100 mph and the plane flys like it's on rails. No flutter, and no other problems.
There are many others that are also having success with the RB. Sorry to hear you didn't find out about the mods that where needed to prevent the tail from seperating in flight.
