Super Tigre 51
 

This has been sitting on the shelf for some time now. The plane looks similar to a Venus with huge tail control surfaces. Some one at the field thought the engine might be dumpster material with all the burnt on castor oil. Any hoo:
11x5 APC 10% - 13,200 ready to fly. Good idle and transition mounted inverted. Plane had elevator flutter coming out of dive. Will try an APC 11.5x4 next time out. MikeB

12600 ready to fly.

This engine just seems so easy to use and adjust. Idles for a long time with great transition. Like the others I have tried, 95 F is too hot for optimum performance. Presently I am having good luck with the muffler staying put. With the extension, most of the oil is blown clear of the plane.

Had the same verticle as the 11.5x4 with less speed.
This same prop and engine would pull my lighter 4* up forever. This plane weighs in at ~ 5.75lb. I think it will pull better when it starts to cool down. We had the hottest July on record this rear with May and June way above normal also.
