Just got back from a contest in which Pete Cunha flew his 46 size T - Bird with the Evo 60. Ran excellent. His main comment was do not use our common stunt fuel . Use R/C fuel 10/18 or so. 5/18 . It does not like lot of oil. This was in the initial directions from the designer. Very smooth , easy to start,
nice soft 2-4 break . Does not shake like the ST .60. This is an excellent 60 for $139.00. Comes with 2 venturi, and two mufflers, uses inexpensive fuel.
If you do not want to run a pipe or pay $400 for a motor here is a good one
