Tower had the Super Tigre G-90 on sale for $99 and with the discount that is closer to $80. I should have bought one! I'm just worried about the weight of the "big block" motors.
The G-90 ISbased ona 61 size engine. The "big block" you speak of would be like the old OS .90f sr. They are much larger in physical size and weigh more.
Yea, but I still may get the ST-75 instead. The pipe for it is quite a bit cheaper and easier to get. The 90 requires a step up to a 15cc pipe which is quite a bit bigger and more expensive.

Don't know. Still in the planning stages. I was really hoping the 55AX was going to do it for me but I guess not. The Jett stuff is really cool but he is very proud of his work. Still may consider a 60 or 65 from him.


If you want the most power in that size range, you should consider a Sanye (Magnum, ASP, SC, etc.) .91 two-stroke engine, or even the Tower Hobbies .75 two-stroke engine. The latter is reputed to be very hot and well behaved. When I was looking for an engine in this size range, the TH .75 was out of stock, so I opted for an ASP .91 two-stroke and haven't been sorry once. The stock TH 61/75 muffler has a reputation for being a hop-up item for other engines which fit the mounting bolt pattern, such as OS.

I am a Super Tigre fan. However, I do not feel that it is the power leader in available two-stroke engines in this engine size/price range. I own several G90's, so I do speak with some hands-on experience.
