Reading this thread reminds me of a thread from 2009/2010 (
http://www.rc-monster.com/forum/archive/index.php/t-24497.html) where a 12s capable car esc was already discussed about (with Pdelcast) ... too bad it wasn't released then, but now with heavier 4wd cars around, especialy the losi 5iveT it really makes sense to step up from 8s. I know that i'm pushing my 8s XL2/2028 setup beyond its limit when powering
my Losi 5iveT as i'm able to average up to 100A during a run. This really is hard on every electric component. The xl2 ESC can reach temperatures up to 100°C (212°F) within 5 minutes at this power levels and aside from the batterys beeing pushed hard the ESC becomes the bottleneck (2nd would be the motor).
Having said this i'm really looking forward to a possible 2nd attempt to release a 12s car esc. Seeing the new 800kv 2028 motor beeing able to rev up to 45000rpm seems to indicate this time it could be for real ;-) Using a 10 to 12s setup in a Losi 5iveT should unleash its true potential.
I sure am also eager to see how much more the new 2028 is efficient compared to the old one. Maybe an even bigger motor is the only proper answer to cars as heavy as a Losi 5iveT.
On a sidenote ... even in a lighter (11kg/24.2lbs) onroad 4wd car (FG Porsche 4wd) it's not too hard to reach similar temperatures within the XL2 ESC (car geared for 60mph/95kmh).
I think the time is right for "the" next step.
