Hi, I found out that the BEC in my ESC is only rated at 2 amps. It is suggested by other flyers that I need 3 amps for my AXN Floater.
If I buy a seperate BEC rated at 3 amps can I just plug the end into a spare channel? I believe I still need to plug in the BEC off the ESC into the throttle channel to maintain speed control?? Thankx for any advise.[8D]

You will have to remove the power wire from the lead going into the throttle channel to use an external BEC

Though frankly I doubt the little bitty servos in that thing will draw anywhere near 2amps

Hi, I was just going by a common comment about the ESC needing more than 2 amps for the AXN. About the BEC, wouldn't the seperate BEC simply supply add extra current for the receiver if connected without removeing the power lead from the original BEC??

If it were two batteries, yes that would be the case.

When you're dealing with 2 BEC's when one is an ESC, sometimes they act weird. Try it and see what happens.

Better yet, don't. There's no reason to have them both supplying power & Barracuda is correct, it might act weird not to mention potentially frying something or crashing the plane.

There's another very good reason to run a BEC & that's protection from a fried ESC. EP sailplanes tend to beat-up ESC as the motor is usually run full-boar with little or no run up. You get a pretty big spike dumping full power into that big prop all at once. If the ESC goes poof a separate BEC will allow you to continue to control the plane for a safe landing. Without one you stand a good chance of losing the plane if the ESC goes up in smoke... crunch.

Thankx guys! After doing some more research, the above advice makes perfect sense and I will follow it![8D]
