Which Engine for a Sig Tri Star

I'm going to Perry and want to hunt down an engine for a Sig Tri Star. Recommended engine is a .15 2 stroke. I'd like to get the strongest engine so lets hear your recomendations. Will work on keeping it light with mini servos and lithium or NIMH battery.

Thanks, Pete

See if you can find an OS .25 FSR NIB. :D....you'll like it.

Thanks Fly Boy Dave. Will keep and eye out for one. I want to come up with a "short list " of 2 of 3 engines to hunt so I'd be sure to come home with at least one of them.

RE: Which Engine for a Sig Tri Star

please lets not go through this again with recommendations on a 25 for this plane. You will never get it to balance correctly and it will weigh a ton . It was never designed for that size motor and will really do best with the lightest motor that you can get into that backend.
I used a TD09 on the first one and it was incredably light and a great performer. The next one had a Nova Rossi 09 in it that upped the rpms and the performance level.
I can't tell you what to do in light of the fact that everyone seems hell bent on putting a 60 in a plane designed for a 20 and saying that you'll have superior performance. In this case it ain't necessarily so.

I hear you Dennis. I want to go light with mini servos and prob Li batteries so As in the 1st post I wanted to get the strongest lightest engine choices and then try to compare weights and power.
