All my currents jets are as Daniel explained above CB200 direct feed by two Lipo 2s (7.4 V) and all HV servos....
BUT my new coming jet will have a CB400 two Lipo 3s (11.1 V). The CB400 will regulate to 8 volts still safe for all my HV brushless MKS servos. My electric retracts, brakes and afterburner lights are feed from one of the BEC of the CB400. The other BEC of CB400 will feed the power to my turbine ECU....keep in mind each BEC can be regulated to a voltage 5V to 8V.
Just two 3s Lipo's on board to feed everything... Less clutter is always better
Im enjoying my Jeti system...
