RE: 42" MRP Fountain build........Here we go!!
I have to agree on the Turnigy... Another nice thing is that they do auto low-voltage detection, built in BEC, and the single connections are easy to solder. I'm sorry that my Castle 240 LV fails on all three of those points!
Hopefully you'll hit mid 40s or better with that setup... But that ol' 42 sounds a tad big/heavy, not sure. YOu'll have to let us know.
