the last time i ran the dual setup on 24nimh the motors were cold after a full run!.....the dip switches were set totally wrong!...i think they were set for a glider airplaneor something,not dual BL aluminum beast from hell!...it was fast before,i want it to fly!!!!!!
i would strongly recommend to use a fan on the esc and start with a small pinion. check the temps on the esc. the 18.97kw is not such a powerful esc. its expensive and five years ago it was one of the few options available. by now things have changed and technology moved on. no one talked bout castle, mgm, quark or others those times. it was more or less hacker, schulze or bk back then. from a today's point of view the 18.97kw is much too expensive for what it can do imo.
