Hi to all,
Getting my Raptor 90 3D back in the air, im going to run a OS91 SZ-H PS Hyper engine in this bird.
I'm not too sure what muffler to run with this engine, "Hatori" or "funtech".
Im not into hard core flying, just flying around doing some basic f3c flight etc.
Any suggestions would be appreciated with regards to a muffler choice.
Looking at getting the best performance from engine and muffler.
Thanks
Neil

I would go with the Hatori
There is a pipe purposely made for it and I think its either the sb 18 or 19

A quick check on Hatori pipes will confirm the number but I am sure someone else will confirm
