Wow. You can't just drop that out there without telling the story.


The cppro will tell you when the battery is in need of recharge, it will no longer sustain a hover. When you notice that you need significantly more throttle to hover or maneuver, you will be landing pretty quickly.

The eflite transmitter is basically a standard 6-channel radio with built-in eCCPM mixing. It has a buddy jack on the back, the round one, a standard patch cord will work with the radio, but I don't know if the radio will work with FMS since you can't turn off the eCCPM mixing feature in the TX.

Don't overdischarge your battery, let it cool off a few minutes before you recharge it (I put mine in a fireproof tray until I'm sure it isn't on fire, that is, it is in fact cooling down and not continuing to heat up), don't overcharge, don't charge at more than 1 C, do use a cell balancer, inspect carefully (and put in the fireproof tray for a while) after crashes, even minor ones.
If a cell swells, don't use it.
I put a hatchmark on mine every time I recharge it so I can know how old it is. I'm running out of room on some of them, over 60 recharges and still going strong.
