I've done my fair share of gearbox's and the ares gearbox's would be able to take a lipo, will only be using a 7.4v stock tube lipo so not so much current going through it to tare it apart... however the ares gearbox shells are pish but as i said im getting a reinforced gearbox for it and i have bought a g&p m120 motor for it. Should be getting 22~bps.
