Hi Fizzy, Nice to hear back from you. I flew it with 2 -2200 2s batteries and it was a little tail heavy. I got the 3300mah 5s battery in today finally. The extra weight should even out the CG hopefully and give a lot more flying time. I put a quick disconnect plug on the outside which works great and I was able to reach in through the open windows without to much difficulty to get to the batteries. I wrecked my super sportster however. I got to far down wind and trying to concentrate on one other guy flying and another trying to take-off. I lost sight for a sec and went into a spiral and couldn't seem to get it out in time-oh well I've now ordered the Escapade from Tower Hobbies to replace it. Hope you are having good flying weather out there in California. Terry
