Stuart, I'd be concerned about the way you mounted your battery and RX because I've had several experiences where the self sticking Velcro has come loose after being in the hot sun for a while. I secured mine down with a wrap of Velcro, and in the case of the battery I blocked it from possibly slipping out by using a really light piece of 1/4" balsa. Under these I put some soft neoprene as a shock-absorbing device, but I don't know if that's necessary.
