I can also agree that 10 lbs is very heavy for that plane. Thats also why i decided to go with the saito 100 instead of the 120.

I might add if you anyone is trying to find an exhaust for the plane. Dont go with the davis diesel exhuast. I just recieved it today and test fitted it on the plane. You would end up cutting more of the cowl than the stock will. Im going to try the saito's flex pipe for the last and final try. If not stock i go.
