No, not really. The servos will discharge the capacitor as well.

I used to sell them for cars with BEC, if the drive battery dropped out momentarily this cap would help, still have a few somewhere.

Nice save.

Not with this setup using the Smart-Fly Power Expander as the servo power is isolated from the Rx power with the use of a regulator and if you look closeley at the pictures there is only signal wire connected to each channel, except for Ch1 and Ch9 but those are the regulated feeds.

Re: Never Again!

Isnt the Cap there to help dump to ground any high frequencies that happen to be picked-up in your DC supply?..I think it acts more of a filter.
