Re: [DFTF] Motors... ...Drive Motors...
I consider 4 CIMs in the DT a minimum as far as motor power is concerned. I would start there as a baseline.
In 2008 we built our drive system to use 6 motors in total, 4 CIMs and 2 FPs. We did not shift, but we were still able to move pretty quickly around the track. I've seen a gradual increase in the number of 6 motor drives over the past couple of years, but its still rarely used.
I cannot speak to using 775s in a drive system, but I will tell you that they caused NOTHING but problems for us in our elevator this past season. I think we went through 8 or 9 motors and each and every one of them was case shorted. This in turn caused widespread electrical issues such as causing servos to twitch (launch minibot prematurely) and smoking Jaguars. We will avoid them as best we can moving forward.
The FP has changed several times over the years, and I think the newest iterations are much more robust than their smoking older siblings. I wouldn't hesitate using a FP in most applications now.
