RE: Official HPI E-10 Thread
ive been using cheap ones from ebay. the tricky part is finding one the right size. mesure the nimh pack and the hole for the battery. then just search for the cheapest 11.1v that fits, try to look for around/over 3000mah.
i was using a tiny 11.1v 2200mha good for around 10min
i found i was running mine on both 2s 7.4v and 3s 11.1v
rather than swaping the esc fan each time i swaped battery. i soldered the fan wires onto the esc bec for the reciver. now my fan allways runs at 6v rather than battery voltage. yes the fan runs a tiny bit slower but ive never had the esc hot to the touch. i often wonder if a 35a esc really needs a fan at all.
ive just put one of these esc into a small water/air tight box. so far so good
going lower on the pinion will reduce load on the motor, increase torque and lower top speed.
my last setup was 3900kv 11.1v 34t pinion. the pinion is so big the cover wont fit lol
