Engine Selection?
Hello,
Anyone have experience with the following engines.
Echo 61 cc twin from chain saw.
Mac 60cc single from early craftsman chainsaw.
I have both and am trying to decide which to convert and use on a fun fly type airplane. From my web searchs, it looks like the mac will perform similar to a G62. Understand the BME 61 uses internals from echo 61. BME web site says it'll swing a 24" prop "with authority".

Prop, rpm etc observations would be appreciated.
