Your MM setup
 

Can I see your MM setups? What I mean is, if you guys are running 4S or 5S lipos in your MM, what are all the mods you do to it in order for it to work fine? Regaurding caps, BEC's, fans, etc.

One question also.
I just hooked up my CC BEC to the power wires and reciever, but whenever I punch the throttle, the reciever turns off, and regains connection a few seconds later. This doesn't happen when I do not run the CCBEC though. (Running 4S lipo by the way.) I also bolted a novak fan to the speedo, but when i run the CCBEC, the fan doesn't function....:whistle: Any ideas on this?

The CCBEC is the issue - I have had similar issues with them, actually. I replaced one on my RC8 for the same symptoms(put a UBEC on it and the problem went away). I suspect perhaps some of them can't handle the voltage drop quick enough, and drop the signal temporarily. Castle will almost certainly replace it, though. I have had some that work perfect, but I have had this same issue that you are having. I say run a rx pack or another BEC for now, though. I am almost certain that the BEC is the issue.
Also, to run 4s on the MM, you simply need to disable the BEC and use some sense with the motor and gearing. A fan on the heatsink is also highly recommended. 4s won't need any additional caps, though I use a 1200mf 35 volt cap on some of mine(I have these individually or prewired to some short wires for easy installation - I gotta get them listed on of these days!).

Oh by the way I got all the parts for the conversion yesterday Mike, everything is perfect, except for the CCBEC :lol:

Do I return the BEC to you or send it in to castle? Anyways I do not have another BEC so i'll run a reciever pack for now.

Have to return to Castle, best to give them a call and you will require to fill out a form http://www.castlecreations.com/support.html

Yes, please send to Castle directly. :)
