RX8 or MMM combo?

So seeing as how we have apples to apples, how do you feel about the start up on the MMM running the neu versus the RX8? Also have you done it with the latest firmware update on the MMM that was just released?

Negative on the latest firmware. The MMM finally gave up the ghost about 3 weeks ago due to the upper case releasing itself from the lower case and then having it's PCB have some little transistor thingies get knocked off. :( Ran a R1 Pro for the meantime...now it has been replaced with the RX8.


In regards to the startup, it appears to me that the MMM may have the edge in terms of being able to run both sensored and sensorless motors. The RX8 seems to cog just a hair more than the MMM did...which wasn't too many times.

In terms of power delivery, it also appears that the RX8 might be a hair shy of the MMM. I don't have a data logger or Eagle Tree to support this (although if anyone wants to send me theirs to borrow, feel free - I promise I shall return it in perfect working order), but it's just what I appear to observe. I'll take a further look into the RX8's settings...it could also be that perhaps I'm not doing something right.

So far, it's not too bad. I'm a little disappointed, mostly due to it seeming to be more or less the same as a MMM. With the $334 price tag, I could have gotten 2 MMM's.


BUT.....I shall withhold my final judgements on the system AFTER I properly race the RX8 and run it with the sensored motor.

I shall strive to both this weekend.

Most likely the motor timing. Timing on caslte products is measured in degrees and Tekin uses their own scale. 10 degs on the MMM is way more than a timing of "10" on the tekin. I think a timing of "30" on the tekin is the same as 10 degs of actual timing.

Did I read somewhere in this thread that you had to add your own caps to the RX8 (as opposed to the MMM which already has them inside)? I think maybe it was Tex that said that. But I just looked at the manual online, and I didnt see anything about that.....
