Is it strong enough? We can say, Yes it is…
We have testing it and flown for nearly two years, we use it also for ACES aircombat championschip (lot of Gs flying) with no problem, you should be only a little bit more careful when landing.
…or just give a look to this video, I guess lot of Gs:

A few pictures of the p-51. The wing was able to support 8.14Lbs of weight! I didn’t hear any cracking or popping, I probably could have added more but I didn’t want it to break!
