Finally had some time to start setting up my Synapse, which arrived last week. One of my servos actually arrived loose and I agree they are low end and will probably strip easily. I plan on putting in a 4S 1500 Flight Power 25C battery. I watt metered a 3S TP 2100 and only registered 12 amps and around 125 watts so there is room to spare on both the esc (25 amp cont 28 bursts) and edf (12 amp cont 28 burst 275 watts surge). 4S will require carefull throttle management and throttle curve programming. Should fly her today so we will see.
