Good Day Xtraflyr,

I am using 4.8 volts.. I also have a bisson muffler as well with 1 in pipes on it. Flew it today and I am getting the mixture sorted out.. It was going rich on the down lines but seems to be behaving now. Still wants to go rich on the sharp pull ups. I haven't figured that out yet :0) 21lbs should be a nice weight for the Laser.. As for the burbling.. I would say you are on the rich side..if it was lean it would sound flatter.

Pretty warm here today..not getting unlimited vertical but still pretty good. Looking forward to your report. I would have liked to try the 23 x 10 today.. slowly I am getting this thing dialed in

Enjoy your day
