Howdy,
I remember reading some time ago, someone put a jet engineering, incowl muffler into one of these 1/4 scale caps. They mentioned they had to cut the cowl up a bit and they couldn't extend the outlet. If you have done this or had experience with these mufflers could you post your experiences, eg, how big a hole you had to cut in the cowl, if you can extend the outlet without killing the performance etc, and if so could you please provide pictures of this.

Thanks Gilly

Hi,

I have this combo for the H9 cap and OS 1.60fx. I just began the kit, and will be cutting into the cowl sometime this next week. I will try to remember to post some pics for you.

I bought this muffler due to the added torque Dub claims it will add to the OS 1.60. I am hoping for the torque curve of the saito 180/ ys140 with the smoothness and throttle response of the OS two stroke. Total power should be close to 5hp with low nitro. Ye-haa!!

Sounds good can't wait to see them. Also what prop and rpm?

Gilly,
Have you heard one of those Jett in-cowl mufflers? I put one on an OS 1.08 and it sounded like dukey. I didnt notice much of a performance difference. Might have been a couple hundred RPMs. My planes over-powered anyway so I choose cool sound! I wound up putting my Slim Line in-cowl back on.
