The problem for this engine might be making a toungue muffler?

I don't remember where mine is right now, but I didn't run a muffler. The muffler lugs seemed to fit something else, though.

My only beef about the engine is actually just the price point.  I often think about Mecoa when people say there's no one making CL engines. Then I go on Mecoa.com and there's plenty of engines. But, they sure are higher than most control line guys wanna pay.

Also the veco 19 is usually on sale for only $10 more than the 18. And we all know how great the 19 is.

I have 3Veco 19 BB one has a rotor in exhaust  to mount  muffler, the other has plugs in rotor holes, and the 3 rd one is just plane. are they any good for stunt?

Oh goodness yes!
