If you break in that engine correctly and eventually run it low oil and low nitro you will have a good workhorse for that airplane. It is a heavy motor so expect plane weight in the neighborhood of 14-15 pounds. I had the ST-3000 on this airplane and it flew it well until I dead-sticked and plummeted into a tree -- this airplane will fall like a rock with a heavy engine like that on it. IMHO it is still a better solution than the Saito 150 you originally planned on mounting.
