Hi Tom:

I am having a problem with the CG setup on my Edge 540 with the G62. This caught me really off guard since the airplane was designed around the G62.

The following are the numbers from my CG software. The same used on the big airplanes.

Total Wgt: 18.75 pounds
Distance from datum line to MG axels:18 inches with Wgt LG 145.0 oz=2610.0 moment.
" " " " " Wgt RG 130.0 OZ =2340 moment
Distance from Datum to Tail wheel: 71.0 inches and a Wgt of 22 OZ =1551 moment.

At these numbers the CG is 21 inches from datum and recommended to start is 25 inches from datum.
It will take 26 oz's in the tail to move the cg to 25 inches. I have no idea why the LG is so much heavier.

My 8 oz RCVR battery is located right behind the trailing edge of the wing along with my 4 oz ign battery. I do have two standard servo's in the front part of the fuse 4 inches behind the muffler for throttle and choke. Four servo's in the tail.

I sure hate to add that much wgt to the tail. Wing tube tight very tight.

Looking for ideas and would like to from other people using the G62.

Thanks
Tom W
