Quick Fly
Well........I just broke my t/r blades on a flight attempt (2nd attempt). My tail is not holding or working well at all. Still need to sort things out.

Right now I'm not sure. I have a small pinion and am just trying to get into hover with a straight throttle curve befor I go to governor. Is yours flying?

I just about got my QWW Bat 26cc back in the air.
My Quick of Japan helis are flying , EP8 Expert with 430mm blades, and the EP9 with 470mm blades....
On my EP9 with 470mm blades I am running a 2600RPM headspeed. Very powerful heli...

WATCH YOUR TAIL...
JImbo...If you go for the 25-2600 headspeed you MUST consider changing the tail pulley to our 26 tooth...You may have only 22 tooth.
Do the math the tail will not hold....Using a 28 tooth would be better still.. You want to keep the tail RPM's between 8-9000 RPM
