so I finished the conversion and I was lucky I didnt have to do any rework with the wiring(desolder, resoldering) I am using 2 Flightpower 5s 3700 cells in series so the battery side is heavy around 950 grams. Iam not a racer so I will see how it goes but I would like to get a couple of 5s 2500 packs to get a better weight balance on the chassis
