Get the V2. More power, more features.

The V2 is worth it. In addition, you'll be able to get parts for the V2 if you need them. V1 parts are not interchangeable.

I have an older A-10 V1 80mm that I am planning to install a reversing ESC. I ordered a freewing 100A V2 reversing ESC and unfortunately the battery cables are only about a foot long and to get to the battery bay I'll need another 2 feet or so. Will more capacitors need to be installed on the ESC end to prevent damage to the ESC?

I would say "no" (re: more caps). Did you order the ones from "spare parts" for the A-10 80mm V2? Those should have had wiring of the proper length. If not, then I would suggest they sent ones from a different model.

Thanks for the help and the link. I agree that I was sent the ESC from a different model. I got these from another vender since motion at the time was out. I could not help but notice that the ones from motion do have extra caps so I went ahead and ordered theirs since they look like they should be a simple instillation and I'm sure in time I'll find a use for the others.

Well, at least we know now what happened. I upgraded my old V1 to the newer V2 reversing ESCs before selling it and I don't recall any issues with wiring length.

One nice effect of the V2 release last year was that I was able to get a super deal on a nicely upgraded and modified V1….:)

Flew it again today with batteries swapped. Same result 45% left on UBEC battery and 65% on other battery. I checked all or the servos and made sure none were stalling or growling. Open to any thoughts.

Took a while, but replaced UBEC with larger capacity one. Same result, 20%-30% difference between batteries. Flying buddy thought that perhaps one of the EDFs may have had a rub or other issue that caused more power draw. Inspected EDFs and did notice some wear on the case of one the fans. Did not find slop or any issue that may cause rubbing. Swapped EDFs and issue went away. Any thoughts on what may have happenned?

Did you ever do a throttle calibration?

Did you ever do a throttle calibration?

Yes, each time I made a change to the setup. Especially mindful of this on twins to avoid asymmetric thrust.
