In the 260, the way I fly, I'd probably use the 105. I have a 102 and will keep it for just this reason.

I am not a 3d hot dog, streaking skward from a dead stop is not my thing. The 105 is really more power than this plane needs.

Just FYI, the 105 is made using Echo chain saw cylinders and pistons. The 110 cylinders were custom designed and made for BME.
