hey guys running a bj 29 with the stock 1800kv motor with the stock 80a esc and turning a x642 s&b prop and have 2x 3s 5000mah 45c hyperions ive been running it on. my question is that if i switch over to high timing should i prop down to the x442 i have or can i stay with the x642? i have hit 125 degrees on the motor but that was after running it all day in mild chop and a few all out runs. also i will be repairing my old bj29 that split right down the left sponson seam so if anyone has some high quality epoxy resin for fiberglass and carbon please let me know. i just need enough to put a thin layer of cf on and laminate it
