Status: offline 		I recently purchased a 30% Lazer that I believe was produced by "Aeroworks" several years ago. The original paint was purple and yellow, it was repainted in the Bud-Light colors. If anyone is familiar with this plane please help me with the CG location!!!!!!

I have an Aero Pro Laser with a G-62.

My CG is set at 51/4 " back from the wing leading edge and this makes for an aircraft that falls out in slow flight.
I read in a thread here that it has excellent slow flight characteristics, but since the plans call for a 40cc ( I believe the 40 ZDZ would be perfect) I wanted to offset the weight of the G-62.

I'm going to go forward on CG ( plans call for 4 7/8" - 5 1/4 " not much range) I'm going to go to 5" and see if I can improve things.

What engine were you going to use on Yours?

At the bottom click on Airplane trimming.

The trim chart is used to set up for precise flying. Adjusting the CG is just one step. Lateral balance is another which makes the plane fly more precisely.
