I don't know how you could balance and know 82mm vs. 80mm on your finger tips. I wouldn't be able to.

I always find the thing about mid-wing planes is they always fall to either side when balancing as the CG is above the balance points. I have to keep tweaking it back and forth and see if it has a favorite side to fall to.

I don't know if you could even tell much of a difference from 80mm from 82mm in flight even with zero wind and a perfectly trimmed plane. I doubt I could.
Honestly if putting the plane on a jig will give you more confidence then do it. What we are trying to say is that the recommended CG is just a starting point. It is not a set standard that needs to be upheld. CG is something you need to check and feel by flying the plane. If your initial CG on the bench is close to what they recommend you will fine. No need to get worried about it in any way.

Please excuse me if this has been discussed but what are the alternatives to the HS-65MG's?

The glacier packs performed great today. Flew them side by side with the GFORCE and glaciers performed much better. The gforce are very very hot when they come down and the glacier packs came down cool. In fact they were so cool I didn't even wait to charge them. Just hooked em right up. the glacier packs have a lot more power too. I would say vertical climb is 2 times as fast. I love to enter KE spins from a vertical upline tumble but don't have the velocity with gforce but i can do it no isses with the glacier packs.

I would bet they are the exact same as gens ace. side by side the 2200's look identical to gens ace.

I cut off the excess on the two lower motor bolts and have the 2200mAH dead up against the firewall. Everything on including APC prop, spinner, and wheels and CGs around are 83mm.

I have an ounce or two of sticky lead around. I might measure out 1/4oz at a time and put bit on the firewall until I get to 80mm. Then if I don't get the battery smack up against the firewall, I still won't be tail heavy.

I think the recommended CG is usually a sport flyer style CG. I've found when you go with the recommended CG for the first flight most of the time you will adjust the pack back from there until you find the spot you like but never forward if you go with what's recommended. Don't worry about it being exact. The other day my battery partially ejected in my SHP and i thought my servo wasn't centering when the plane started climbing i flew around for another minute then landed. The battery was all the way back by the wingtube when i opened the canopy Being tail heavy won't kill your plane most of the time it will just make it fly poorly. You will probably end up moving the pack back a bit anyways so don't worry about getting to the 80mm mark.

No problem man. Now we just need this 110 degree heat to get gone so we can fly without frying our skin and our electronics!

I don't measure CG, just adjust my Edge to fly straight both in normal and inverted. And this way I feel it comfortable. Just move battery a little bit forward in windy conditions.
