I don't get mad, not why I'm on here.
With 4 leads going into the reciever, I can handle at least a 20 amp spike. The connectors are rated at 3 amps, but I'm pretty sure they could at least handle a 5 amp spike and probably more. With that going into the receiver it's not going to every servo at the same time in most cases, just the one 's that are needing the power. I'm a firm believer that if you setup your servos and linkages right, no binding and the correct geometry, then there is no reason to draw 50 amps in the first place. If you are using A123's and you are using 1000 mah per 10 minute flight, that's when you have problems. If you are using 200 to 400, then I would say you have a pretty good setup. My biggest thing is adding too many components that can fail. If it's electric it can sure enough fail. If a servo, or a single battery in a dual battery setup fails you have a chance of saving your plane
