Hello,

I am new to this forum... please bear with me.

I plan to put a .91 OS RZ DH engine into a 60 scale helo. I would like to know what type of muffler or exhaust to use??? This is the rear exhaust engine. The body is the bell 222.

Thanks, Don

Might help by listing the make of the mechanics and body as well so the nitro flyers here can better help.

it is unusual to have a rear exhaust engine for a 222. there is a scale muffler from century and hirobo that should work as well.

drive a rotary, fly a rotorcraft

watch out for

I used the Hirobo one on one of my heli's!

Be warned friend the Hirobo ones are IMHO over priced! Have a look at both Century & Hirobo

Re: Need Scale Muffler Info

I have seen the Scale mufflers by century and wonder if the muffler will "inhibit" the movement of the slide throttle that is seen on the OS engines. I wondered about the OS .91 in that the exhaust exits to the rear, which will go out the bottom of the helicopter. Would it be possible to mount a "Pitts" typr of muffler and allow it to go straight out the bottom??

Thanks to all that have replied or contributed.

My thoughts

Can't speak for the Century, but if its anything like the Hirobo, its miles away and presented me with no problems!
