The thing that would worry me is the vibration in that wing. The metal bolt may vibrate out. I've never had problems with my nylon bolt. In fact someone else so kindly turned on their transmitter (which happened to be my frequency) when I was about 200 feet in the air at full throttle. The rest is history and believe it or not the nylon bolt was still intact. The rest of the wing and airframe were destroyed. I think the nylon is plenty tough.
