I was having problems with the tuning which I know I am good at... no wonder... don't laugh guys... I had the breather pipe and the tank pressure pipe swapped accidentally when I was cleaning and doing maintenance... yesterday I took it apart and there I saw the problem as clear as daylight... I felt like an idiot, still do...

ahh..don't be so hard on yourself....you are gonna do alot dumber things than that.......then you'll be just like the rest of us LOL

Yep, it happens. To avoid things like this I color code my fuel tubing. I use blue tubing to the muffler pressure, pink tubing for the fuel feed, and green tubing for fuel fill when I use a 3 line tank setup. This way I can always know at a glance which line is which.

Ken

been there done that lol

I flew after the noobness today... wasn't awfully powerful as I thought... will I get more speed by dropping in prop say to 12x6?... at moment I use a 13x6...

you'd get more spped by going with a 13X8...but more drag on approach....split the diff and go with a 12X7
