glassdoctor,

I don't know how old you are, but do you remember and movie with Robin Williams called "Good Morning Vietnam?" That part where he's doing his radio bit and making jokes about how hot it is. I could have sworn he was talking about the weather down here. It gets hot. In fact, I got to a point that I was running my nitro engines at 280 because I got tired of loosing the performance from having to run them so rich to keep them cool. I'd break 'em in to run hot and just kept bearings on hand.

Anyway, what do you think about the Hacker motors. If they are a good motor, I'd pick up an 11L (if it's better than the Feigao) and see how that runs. For the price, it can't be beat. Here I go again, talking in circles.

I think I'm trying to hard to make sure that I get the right motor. I'm making the switch to electric in the buggy because it's supposed to make my like easier. I don't want to wind up with a bench with a dozen motors on it because I couldn't find the right one. I just sold six nitro engines and threw six or so away.

Now you see this. This is how brain fried I am over this motor thing. Now I'm looking at the Hacker L can. If I go that route, I might as well get the 1512. Really, the whole cogging thing has me a bit worried. The Hackers are two poles and should run well with the MM. I'm just not confident that Castle has this issue on the front burner. Months ago, when I first got my Mamba Max 7700 system, they told me that they were working on a software rev limiter. That's why I got the 7700 to run on 3S Lipo. I thought, great...I can get insane and protect the motor with the software. Well, it's been a while and still no rev limiter. I could take quite a while for the "fix" on the cogging issue to come out.

The oddest thing about the cogging issue is that I emailed Castle about doing an emaxx build, before I decided on the buggy. They told me that none of their motors would work, and recommended that I use a Neu motor with their controller. I think it was the 1512. He said it was what he had in his emaxx. If he does, he should be more than aware of the problem.

Have you tried programming your MM on the 'puter? Did you play around with the timing settings, in conjunction the startup power and punch control settings? Since four pole motors are more sensitive to timing, I'm wondering if tweaking the MM could at least minimize the problem.

What settings are you running on your MM?
