My receiver is wedged in the foam and sticking up into the cockpit. It's rather large Flysky 8 channel unit. I should have used a smaller one, but thats what I had at the time.Just got back from the flying site a while ago, it flies better and lands nicer without the weight. Maybe I should try it with no extra weight. I shove my batts all the way forward too. My CG seems perfect with the 2 weights remaining.
