Noob needs help - 06.21.2008, 06:41 PM

I'm searching the Castle Forums here looking for some guidelines for setting up my MMM in Castle Link. I'm coming up dry though. Maybe it's the words up searching for, particularly the "motor timing" setting on the "basic" tab.

As you probably already know, you get several choices.

Highest (20)
High (15)
Normal (10*)
Low (5)
Lowest (0) Best for Bashing it says.

Normal is what it auto detected for me and my setup. MMM 4s (two 2s in Series) a Tekno 1515 1Y. I thought there was 0 degrees of timing on these brushless motors. Or am I getting my terms confused here?

When I first got my truck setup I had the absolute worst glitching I've ever seen. I switched out the bone head traxxas radio/rx and am currently using a HPI FM tx/rx from a RTR Baja buggy. It works much better and will suffice until my Futaba 3pm gets in from Tower.

Anyway, I am seeing some serious hesitation from my truck under full throttle, either from a stand still or running WOT across a large soccer field. I'm not sure where to start the trouble shooting.

For one thing, I really have to scratch my head over the fact that the MMM comes with 6.5mm bullet connectors on one side to handle all that juice being pulled from the motor, and then on the battery side I have some tiny solder joint on a fraction of the bottom diameter of the 10ga wire on traxxas connector. See photo:




I just can't believe that there's enough contact area there to get the job done. If there was, it would stand to reason that surely the 4mm connectors that come with the MM would have sufficed, right? I mean, if that crap solder connection is good enough for 16v and 110amps, then why ship MMM with 6.5mm bullets?

I'm running Max Amps 2s2p 8k's and we all know how the packs need a 25% buffer over what your system requires. But I should have that covered up in spades. 1515 1Y is 110amp max. Max Amps 2s2p 20c 8k's, should, by definition, be 160 amps.

I'd really like some opinions on these issues.

I know what the search button is for, too.

Thanks
