Caution about using the capacitor with an ECU. the slow brown out when you shut down can cause funky things to happen to the ECU.

I have been running the Dcup since the first prototypes. Put a separate switch on the DCup so that you can shut it off just before shutting off the jet, so that when you kill power, the jet shuts off now. I nearly lost an aircraft because of an unexplained failsafe, and i troubleshot it down to a couple things, with the repeated brown outs when I shut down power being the thought of the main issue.

Its no problem on a receiver because it simply resets, but the combo of it trying to reset and the low voltage on the ECU caused some condition we cannot explain.

So again, if you are running turbines with the DCup capacitor, put it on a standard switch so you can lock it out when its time to shut it down. Its a wonderful product, it really smooths out transients.

PM me if you need to discuss further..
