Hi, Just finished this project,the Life boat looks great, same set up as J Beazley as I am a novice and no idea how to R/c boats, other than Sail winches and rudders!
Great article, it has helped me in understanding motors, engines etc.
I have 2 x 380 motors, a viper 15a esc and a dodgy 9v 1800mAh rechargable battery from an old r/c car,she ran fine for 3 mins, cutting out 30 metres away, a short range i thought, as my r/c yachts will cover over 150 metres using the 2 channel Futaba gear, possible esc interference? but she ambled along for 10 mins at a medium slow pace until dying completely.
My questions are, is there any way to increase range, (re-siting esc?)
and you have said you may upgrade your battery, what would you be looking at, more V or mAh, i have seen 7.2 2100mAh batts on ebay but am unsure if the esc can handle it.
