well, i made some different connectors up for my 5000mah 2s lipos, and a y connector to join them to the esc, this one isn't running standard evx2 and titan, its a brushless setup. didn't have a spare lvc so just ran bout 15- 20 mins which i new would be fine (checked after and i was well in).
very happy with its performance, climbed about 6 foot banks on throttle no probs, might consider going up to 3s, but i do want them mounted in the battery trays to keep it clean, and as the 2s only just fit i doubt i will manage that.
just about to finish my run and she stopped on some rough ground, motor and all still working so i had to carry her back, these things should come with a health warning, they are soooo heavy..
once i was home a strip down revealed the spur gear had come loose, what a great design how these motors fit in, all rectified and loctited up and she ready to go again.
these cars are just great, put a grin on my face right away.
to be fair i don't think it needs any more speed, she's a big old girl and not a racer, fast enough i think, really enjoyed the first outing.
