I'm thinking of getting a 61 2 stroke engine. I was wondering if any one had any luck with a thunder tiger pro 61 or the OS 61 fx?I want to get the thunder tiger because of the price. I have a 46 fx and a tt 46 pro and the Thunder tiger in my opinion is a little better. Well thanks

If you want to know what engine would be good for 3D it really depends on what airframe you are mounting it onto first...
