HELP ! MMP + Spektrum RX = cutting out ?

[BrianG]

If you are running 2s the voltage could be dipping under acceleration. BECs need around 1-1.5v higher than the output to run right. So, if your BEC is set to 6v, anything much lower than 7v at the battery could cause the BEC to dip below what the rx needs. You could try setting the BEC to 5 or 5.5v and see if that helps. I would keep the glitch buster cap in there too; it may not noticeably help, but it does smoothen the voltage and reduce any noise.
