Kontronik Jazz 55-10-32 for 8s buggy;-)

[othello]

Solid piece of hardware. Mine even worked without heatsink used in my 3.9-4Kg Buggy with a Neu 1512/2Y (1400kv). With heavier vehicles a small heatsink is recommended. I fed it with 9-12s A123 (11-12s with a Neu 1515/2Y - 1100kv).

A more up to date software would make it even better as Lutach already mentioned.

I would not worry using a 1300kv motor with 8s lipo (as long as you can gear your car for higher motor rpms). My old Crono buggy used a 52t spur (more likely to be found in a truggy nowadays) and had an overall gearing of 1:13.2 with a 13t pinion. Perfect in conjunction with a high revving motor in a buggy. Tons of power, low amps and long runtimes. My Neu 1512 with 1400kv reached well into the 42000-45000rpm range and stayed reasonably cool.
