Rodr

I guess if I run the four pipes into two outlets it may not sound quite like a tractor but then again a tiger moth sounding like a Savannah could be as bad. The Jab 3300 has the Rotec TBI and the 5100 is fuel injected so mixtures are controlled and exhaust notes are great.

Thanks to you all, its going in a Fisher Tiger Moth replica and not a lot of room, I run a Jab 3300 and a 5100 without exhaust with no apparent problems apart from noise.

Can I run a 912 without a muffler ?are there back pressure issues?

Thanks for that ave8rr yes I know them very well was looking for someone in Aus just to chew the fat regarding building and making a few alterations.

Anyone know of a FisherR-80 tigermoth replica owners or builders as need some advice on my project ?

In 1985 I bought a lightwing with a 582 and would have flown it over the straight If given the opportunity,UNTIL, the engine failed over open country and a safe landing evolved. It was then that I made the decision that I would never fly a two stroke powered aircraft again no matter what pressure came my way. I am still flying regularly in my own aircraft , since then they have been Jabiru 4 and 6 cyl and a 8 cyl in a Mk26 Spitfire and currently a Rotax 912 uls ---4cyl !!!! The engine failed at 107 hrs absolutely no warning and just disintegrated ,my advice since then to any buyer pilot is if you are going to do any serious flying over anything you cannot land on safely then give two strokes a miss!!!!

Anyone out there building a fisher r80 or similar fisher products?
