Hi, I recently got an old HPI E Firestorm 10t in great condition, included in a bunde deal, which I have a problem with.
I have put in a brand new HPI Firebolt 15t Motor (it had a HPI Saturn 27t in it), 19T pinion, a Step Up SU-00186 12T Brushed ESC (Brand new old stock via CML) and I'm using a Flysky FS GT3C Transmitter and receiver and a fully charged 4300mah nimh HPI Plasma battery, which is old but still reaches 4020 capacity when charged.
I turn it on, and for maybe 5-10 seconds it runs beautifully. Then it cuts out.
The esc emits 2 beeps-pause-2 beeps-pause--2 beeps-pause--2 beeps..
Then it will run again for another 5-10 seconds.
It did this 4 times when running, then I got a 3 minute(ish) run with no problems. Then it did it a couple of times again. When I picked it up I could feel the heat from the battery through the bottom of the chassis. Not burning hot, but too hot for a 4 minute(ish) run.
I have tried a brand new 1400mah Carisma nimh battery, which came with a RTR I got recently, and the same thing happened immediately. I took it out straight away before it got hot.
(I know, I know.... nimh, aaggghhh. lol. I don't have lipos yet
I apologise if this is a bit long winded, but I wanted to give as much info as poss.
Any advice would be much appreciated.
Thanks
