Some kind of telemetry feature, even a basic one, would be nice on the MMM- download the info via castle link to your PC or laptop. Temp, current draw, motor rpms would be awesome- even if it had to be a little add-on box or something that plugged into the main PCB, like the fan does or something.
Intelligent Q now:
With regards to the fan issue, can I get a definative answer as to what Castles take is on case-modding the MMM? I would like to do something like BrianG has done and turn the esc into a convertible, but use my own larger (more robust
) 40mm fan to improve cooling, but I dont want to void my warrenty (modified case can be re-used even if the PCB went poof a bit...).
I like to think of it this way; a heatsink on an esc only works with good airflow, and to get good airflow the esc needs to be posistioned like so. Unfortunately, this isnt always possible, so a fan is therefore used to provide artificial airflow, replacing the natural airflow that would be present as the vehicle moves along at speed (certain chassis and shell designs prohibit airflow). I dont believe a fan should be used as a forced-cooling device like a desk fan pointed in your face, that does imply that that the esc runs too hot under normal conditions. Replacing lost or unavailable natural airflow with a small fan is perfectly acceptable in my view. Plus, fans look cool....
