I mounted my OS .46 AX engine at a 45 degree angle so my stock muffler would work. Didn't want to buy a pitts muffler at the time. Clipped the wing also for better aerobatics and so it wouldn't look so gawdy with the full wing in my opinion.

When covering make sure the front part of the covering is over lapping the rear part so wind or fuel won't get up underneath the covering.

Cover from back to front on the fusalage and start on bottom, sides, then the top. On wing and tail covering start on the bottoms then the top.

you'll figure it out...good luck

mine looks silly but flys very well.....I build them to fly not to look at!
