Hi: Anybody knows this Corally ESC specification ? What is it max current and constant current output ? What is the lowest possible motor turns can be installed at 7.2Volts ? Anybody tried the 4.8Volt or 3.7volts Lipo ? Then at what motor truns ? Tks for help.

This Corally MMS I ESC was released 1987 and was the first version of their MMS systems. There were no technical details published beside the fact there was a 8 min. version for 1/12th scale and a 5 min. version for 1/10th scale.
From my knowledge the only difference was the programming of the current limiter. This was not adjustable.

I´m not sure if it´s working with 4 cells as 6 cells were used that time in Europe. Regarding motorlimit you have to think what motors were used in 1987. I think this will be maybe high wind motors also this ESC is very lowprofile with no heatsinks.

5 minute version with heatsink.
Someone ever have seen an 5 minute without the additional heatsink?
