I am debating what 2 stroke engine that I am going to put in my Lil Toni.
I was thinking for a ST G90 or OS 91FX or OS 1.20 AX.

Any feedback from anybody that used these engines in their Lil Toni.
I am looking for the best performance and speed for the buck.

Since there is very little room in the cowl I'd go with the OS91FX and pitts muffler or pipe it. Forgot what the racing guys use for a prop with that setup but it's like a 13x8 or 13x10,, probably smaller. I know I've tached mine at 11,200 rpm with a 13x8 APC.

go with 120AX know of one in WM Midget Mustang CG no problem bullet FASTTTT
all most same # as a OS91

Funny you mention that because i replied earlier then but realized he was talking about the toni. Anyways. I have an OS 1.08 ina Midget but iit is a mouthful. I think the 120 may be smaller (size) than the 1.08 but not sure. Whatever make sure you balance it out.

Thanks for the reply. Nice pics.
