They use one of two motors, each with 2 versions (how the shaft is installed) 3S uses a 3715, 4S uses 3720 (Hellcat uses the 3720)
They start having issues if higher power is installed for more speed. The EPO foam is slick in a way similar to teflon. Glue joints WILL fail. The question is how long until it fails. Higher speed means more stress on the joint and they fail faster.
I upgraded power on the Dynam P51 and I had a lot of issues trying to keep the CF tube wing spar in the wing. I now have the strips of foam that glue in the bottom of the wing panels (glued by the factory) glued in with Gorilla white expanding poly glue, after piercing the foam many times, so the glue can expand into those piercings and pinned in place by several toothpicks.
