Has anyone used the OS .15 CVA engine before? I'm thinking of using it in the Mini 3D from Extreme. What I really want to know is how loud it is...kind of a tough thing to judge, I know....and this post may not get any responses .

I'm looking to fly this plane in a small field a mile away from my home where some guys are flying strictly electrics. I'm trying to decide if I'd become a nuisance or not. I know that .049's can have a piercing scream and I don't know if this little engine would fall in that category. I wonder how this engine would compare to say a 46FX? (which I consider to be fairly quiet).

I've emailed this question to a guy in that electric group, but in the meantime I was wondering if anyone here had any insight. If it's a problem, I'm going to have to setup the plane as an electric, but that will be something new for me...I'd rather just use the glow engine.
