Yup I just did this on my p3p a month ago too. It was a preventative measure. So far so good. I like that this stuff is really light, barely any weight added and strong as hell. I can't see the motor mounts breaking anymore with this stuff around it
Take a look at our stuff and give it a try. Haven't had anybody unhappy with it and the kits give you a lot that will last you some time too. We did crash tests and also have a video in real time showing you someone repairing a cracked Tiny Whoop frame and then immediately able to fly again.
