I thank you all for the replies ! I'm seriously considering the Saito 100 4-banger. I will save a little more up to buy it if someone could tell me that it would POSSITIVELY fit between the stock mounting beams of the metal supplied engine mount. I have always been the one to mount, alter, and mount the bigger of the available on what ever was in question.

So far I have a W.Models 20 Super Frontier Trainer W/a MVVS .28 W/mini tuned pipe on it. It moves out fairly well ! My first plane is the W. Models 40 Super Frontier 40 Trainer W/a MVVS .40 W/stock muff on it. I thought it would out do the GMS .47 but was wrong.... WAY wrong! It must be the stock pipe on the MVVS that's restrickting the engine for the GMS seriously blows it away.

Anyway, I've been a "WireFlyer" all my life, and have only within the last year went solo with RC. I really like it a lot !

thanks again, and if anyone knows if the 100 would fit, let me know. Also, if there is a webcite that I could look up the case dimentions of the Saito 100. That would seal the deal....
