J'EN heli mini pipe .32-.39 on OS .32 in Raptor 30V2

Your muffler is perfectly suited to my Raptor 30V2 - and quiet too - brilliant for sports flying

J'EN heli mini pipe .32-.39 in Hawk Sport

If you are looking for noise reduction to a stock muffler shipped with most 30 size plastic models, this should be near the top of your list of options. I am extremely happy with it's performance and noise reduction and at half the price of a Zimmerman, it's a cost effective general purpose muffler.

J'EN heli mini pipe .40-.53 on OS37szh in Quick 30 Carbon Pro

Just thought I'd drop you a line to tell you how chuffed I am with the 40-53 pipe you sent me on Saturday for the OS37sxh. It is ACE!!.

It allows the engine to breathe and produces very smooth transition between high and low revs with loads of power to boot.

I have used many pipes and mufflers over the years on heli's and can honestly say, for the money it is the best muffler I have used (it easily compares to some other brand names, Ha**ri, M*II, Zi**erm*n etc) and It sounds great! This is the second JE muffler I've had from you and I shall continue to use them on future heli's!
Thanks, Kind regards, Barry Armstrong.

J'EN heli mini pipe .40-.53 in Compass Knight 50

The picture shows one of your .40-.53 mini heli pipes installed on my Compass Knight 50 helicopter.
I am using the OS Hyper 50 engine in the helicopter, considering the price of the muffler I am very impressed with it. The engine develops good clean power and reaches peak output with no problems at all. I don't find the muffler to be overly loud, in my case it emits a nice crisp exhaust note barely noticeable above the general noises of the helicopter.
