definitely the leopard motors are awesome ....... Im using a 4065 2700kv for 1/8tte races with +300 batts and still working perfect (only changed the bearings 1 time)
also I have a 3650 3900kv in a 1/10tt 4x2 with aprox 120 batts and works great .....
also using a 4074 2150kv, a 4282 2000kv and a 4274 2000kv ..... all the motors works perfect and I dont had any problem with none
in the last year I sold all my castle-neu, xerun, tekin etc ....... and at this moment only Im using leopards, simply because are the better motors I had.......
if you see the vids of my chanel will see my cars ...... running only with leopard motors in the last year ...... and winning a lot of races ;)
