Quark Monster Pro Error Question

[joeling]

Hi,

Thanks to the suggestions by knowlegeable members here, I have managed a semi-successful run today.

In frustration of the uncertainties I faced on controller reliablility, I bought an Eagle tree data recorder thingy to try to capture some data to try to figure what what went wrong. I strapped the recorder on & did some bench test. Peak amp while throttling up reached in excess of 50amps albeit for a short time only.

I took the buggy for a test run at my local make shift track this afternoon. The track is very small is no straight but a constant series of turns some tight others not. Mixed in between the corners there is a double & a triple & a table top. Ambient tempearture was about 30 deg C.

I am happy to report that the esc held up & did not thermal. However, the bad news is that I did not manage to last the distance of a single pack as I have somehow managed to strip my plastic spur.

Anyway, here are some photos.

Hi,

Looking at the recording of the eagletree unit, the average amp drawn when the buggy was right side up hovered between 10A to 30A. My throttle EPA setting was only at 80%.

I'm also quite impressed with the performance of my Kokam 20C lipo. Min. of 13.1V under initial throttle while maintaining an average of 15.7V was pretty good in my opinion.

After the disaster from last week, I had to install a big fan & 3 small copper heatsinks (although on the plastic side of the esc). This seemed to be able to keep the temp. to less than 50 deg C (measured on the plastic surface of the case).

By the way, with this setup (12T/46T), my buggy cleared the triple easily with minimal run-up & could clear the table top too. My other buggy with an STS monster truck engine was not able to do that.
