I just bought my SR and am new to helis, ...and being a fixed wing pilot for 25 years ..... HA ..only means I know what the sticks do and that's it ! I wont be lifting off the pad for some time now

I have been flying the mSR for awhile...not even close to the SR to me.
I cant get the stock battery forward enough to achieve an acceptable CG balance, the cowl ( 25 yrs

canopy wont fit then. I do have a few
3S 11.1V 2100mAh Li-Po's which are a little heavier. I wonder if they would be ok to connect. Any advice would be well taken.
thanks
Bill
