Question: I have a VMA-A0026 Avenger 60 ARF Aerobatic Pattern. Can I use an engine with a rear exhaust and a tuned pipe?

Answer: The VMA-A0026 Avenger 60 ARF Aerobatic Pattern was designed assuming a side exhaust and standard muffler. You will likely need to make many changes to the factory engine compartment and mount to accomodate a rear exhaust engine and depending on the engine this may not be possible at all.

 

Tuned pipes that are exposed and attach to the side of the fuselage may be possible however the Avenger was not designed with tuned pipes in mind.
