To bec or not to bec that is the question

[BrianG]

I've had the MMPro BEC exhibit problems on 3s and 4s. Maybe it was an earlier model, but I had 3 that all did the same thing. I found the BEC would basically drop out at anything over around 2-2.5A. Spektrum receivers especially don't like this.

Mine does the same and its a recently purchased MMP

Just running an Ace DS1015 Servo in my Slash 4x4

Servo draws 3 amps or so and the bec voltage drops to under 5v

Tried the cap and it helped a little but was still not stable, ccbec installed and all is well

People blame the Spekky recievers but I think its just that they dont like voltage drops, other recievers / servos are still seeing a drop in bec voltage, just handling it a bit better

Cheers
