Hi Guys
Well I finally got over the Hatori muffler forever coming loose, and bit the bullet , purchased a Zimmerman muffler from QWW.
Irwin was great to deal with. Very well packaged too.
The quality of the pipe is fabulous. Polished like a mirror.
I had to use an extra Zenoah header block between the pipe and the motor, as it was too close to my fuel tank.
1st flights were very lean.
So the usual fly land fly land tweak tweak etc etc.
The video link is from the last flight of the day.
Yes it is still a bit lean, and yes it is overspeeding on descents too.
These will be sorted asap.
There is no 3d in this video, because frankly at this time I cannot afford to crash it lol.
The purpose of the video, is to give you a look at the Maxum on video, and to see what the Zimmerman sounds and performs like.
I thought that quieter would mean less powerful.
But true to Irwins word, it is more powerful, and by a large margin IMO.
Read the video description for why the motor is surging at the start.
Oh, and who says gassers cant crack

Merry Christmas

I should note, that the muffler does discolor with heat.
Irwin told me it would.
It is slowly going a nice bronzy gold. Looks very classy IMO.
Irwin says it can be re-polished easily with stainless polish if you need that chromed look

By the way, it just struck me to mention this, I paid full price for this muffler.
It is in no way shape or form a promo item for me.
Had to say it for the sceptics out there lol.

I too , have the same pipe on my 26cc Bat gasser. Great video gorn.
It sounds very powerful. I got all my gasser stuff from Irwin at QWW , and Irwin and the guys at QWW have been realy good. The best customer service in the business if you ask me...
I can`t wait to get my 26cc Bat going. only thing left on mine is some batteries , R/X and ignition...
Thanks for the video gorn, AWSOME!!!!

PS: I too have paid for all my stuff from QWW. Thanks Irwin..
I don`t know how the tree pic got in there???

Hi Gorn,

Zimmermann is good stuff. I used it right away for the Maxum. In the meantime I also changed the Century muffler at my Spectra-G to a Zimmermann.

Grtz. Paul

Hey Jimbo
Good stuff mate.Yes she's pulling pretty hard now
Gassers are great fun, as Im sure you will find out shortly

Paul
Good decision, these Zimmerman pipes are great.
Now I know that a few guys have had issues with their rear mount mufflers, and that does indeed suck.
But no isues with the regular side mount ones.
