The smoke and RX battery were under the cockpit -- way nose heavy, then moved both batteries 1/2 between the tail and cockpit -- much better, then moved both batteries to just in-front of the tail -- now the plane feels slightly aft cg but tumbles really good now.

I'm using the duralite 4000mah battery for rx and 1800 for the ign battery (it is mounted in the firewall box) & 600 mah nicad for the smoke.

I have approx 100 flights on this plane no damage other than one of my wheel pants came loose. I have since fixed that, and I fly off of grass 99% of the time!
