Hi Stu, thanks for that. I must admit that purely from a cosmetic standpoint I wouldn't be keen on running a pack on it's side, but I appreciate the lateral thinking behind the idea.
Am I limited to around 3200mA LiPos? We are limited to 13.5 brushless anyway, so run time is less of an issue, I just don't want to lose out on power compared to someone running a 4900mA Trakpower for example
