Default mCPX BL2/other blade micros and adding a capacitor

This one is for the electrical engineers. Adding a capacitor to help with burst current... doable? Bad idea?

I have been wondering about this for many years. Apparently capacitors are built into larger (if not all) ESC's. I think it would be straightforward, simply soldering it into one of the main board leads.

Figuring out the capacity would be a bit more difficult. I think enough energy to run the motor for a few seconds would be good. Fortunately they appear to be very light.

Regarding the MCPX BL2, it doesn't seem to bog much, especially compared to Nano S2/CPS/CPX. So I think it would help those helis more...

Youre right. Now that I have had more time with it, I see that the BL2 really doesn't bog all that much. I'm still curious about adding a cap though, as it may still have a net positive effect. Maybe I'll post this in the main forum to see if I can get the opinion of somebody with an electrical engineering background.

I was thinking to add it opposite the power leads on the front of the board. It would be nice and neat that way, and may actually help left-right balance as currently the CG seems to be biased ever so slightly to the right.
