Well it had to happen sooner or later..... I am going to "possibly" have to change the set up in my new stunter once it is flown. The engine is a PA .51RE and I am going to be using a slip on "can" muffler, instead of a pipe. (due to fuselage "bottom" construction restraints)
Just got off the phone with Randy (who else to talk to about "his" engines? LOL!!) and he told me I "might" have to change the venturi once test flights start. That will be a totally new experience for me. IN the past, I just ran what was put in the engine and have nver had to really worry about changing it. Looks like I am about to be drug, kicking and screaming, into the darkness! LOL!! I will actually have to think of the possibility of changing a venturi........ and things were going so easily!
