I've been thinking about getting frp chassis as well, unfortunately i haven't found any stores in asia that has the chassis in stock. I believe i only need to remove the round edges at the bottom and left side of the battery slot as in the picture, red circles for shorty pack, and yellow circles for stick pack.
Hi everyone, I just realized that the battery slot is suitable for rectangular pack lipo (shorty and stick) as long as i modify the plastic that holds oval shaped lipo a bit. The question is, will the modification affect the chassis significantly In terms of performance or endurance especially? I'm reluctant to buy another battery pack just to fit this chassis, but i don't want to make the chassis break easily by recklessly modifying it.
