RE: 40% MX2
My plane is a little different in certain aspects than the production planes. My slant mufflers are hitting the cowl barely, but enough that I'm going to have to cut the cowl. So from what I know you will have to cut the cowl. I wouldn't worry about it though. This plane fies so well you will have forgotten about the holes after the second flight. I have the opprotunity to fly alot of different planes, but very few have ever turned me on like the MX2. I'm in Phoenix right now for a bike run, but I wish I was home flying that bird. It is a plane that opens alot of possibilities on what can be done with an aerobatic aircraft. Insane power with a great wing loading = FUN
