Hey there Skyflying

What kind of muffler is that you have on the Brison? Do you have to run it also inconjuction with the scale exhauts?

...and did you find the Sierra retracts really required thinning out the ribs...I'm doing some serious digging into the ribs with my Sierras!


Any idea where Arthur K is? Love to see how his Z-bird turned out.

best,
Matt
