What kind of power are you looking at for the Phoenix Decathlon? I have a ASP Super Series 52 on mine and its obvious that it doesn't need this much power. I think an OS 46FX would be a better choice,

not that I am going to make any changes on mine (at least not yet).
I have an old HB .61 in it now. Probably puts out less power than the .46FX. It's going to get a Magnum .91 fourstroke. - That ought to do...
