I think the tailwheel assembly is too big for the plane...Its the same one used on the Extra 260, and the plane sits level on the ground....not that is a big deal.
I didnt put the springs on mine yet, and probably wont. I may get a smaller tailwheel assembly though.
All I had for an engine, was an OS.91FS, and an OS 1.20FS, and I couldnt get the 1.20 to fit in the mount, so I went with the .91FS....My freind just got back from the AMA Nats, so we maidened it last night, and he said the .91FS is ok, but for hard 3-D its not enough ( which I expected ).....plane flew pretty much like my smaller Goldberg Matrix........I didnt use the SFG set-up, as they didnt align with the holes in the wing very well, and I wasnt planning on flying it much with them anyway......
All in all Its a nice plane, that flew pretty much as expected.....
