RE: new extreme flight rc 88" yak too heavy??
Zayzay1, there is a lot of talk on the other thread about cannisters, tuned pipes, 60cc engines, etc. You are a little closer to sea level than I am,here in Texas, so a simple, light setup with a quality 50cc engine & standard exhaust will provide superior performance from this plane. It would be much more affordabe,too.
I don't think specific torque figures are important. They differ with geography,air temp, humidity,engine, props, fuel mixture,& probably other factors I haven't thought of.
