Tried searching, but got limited results, and most threads were quite old, so here it goes.
I'm currently running Futaba BLS 275/276 servos in both 700's and my 800, along with the Futaba CGY 750 FBL system. For power, it's a straight shot from the 2s rx pack into the rx and fbl system. One connection into each via a standard 22 awg cable and standard servo connector. Keep in mind that the rx also delivers unused electrons back into the fbl unit via s.bus connection. But again, it's only a standard 22 awg.

Here's where you come in. Will this.... ....coming off the 12s flight packs be sufficient? I can't smack, but I'm always willing to try. And there is the odd bout of poor collective management to deal with as well. I sometimes notice the cyclic servos have a slight temp to them, but nothing too severe. But, any temp has me believing there is a fair amount of current being drawn.

The main reason I'm considering this BEC, is because of the bus system. I feel that having only two 22 awg connections from the rx pack is probably bottle necking the current delivery anyways. But with the CGY 750, there doesn't seem to be any alternatives. Please correct me if I'm mistaken.

If you want the best bec for a 700 then the r2 prototype is the one to get, mine is bulletproof. This is the same bec that was used on the speed banshees that set the speed record few years back. I have been running mine for 2-3 years now and not skipped a beat
