RE: Oxai E-Pinnacle Build
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.
