Can this work with UMX planes or park flyers?

Seems big/heavy for a micro. (Plus I always fly my micros indoors with others.)

I just set the timer so I never put back more than 80% when recharging. Another (rougher) metric is not to go any lower than 3.73V or so. Start with a shorter timer and work up to be nice to your batteries.

Time your flight. If your transmitter does not have a timer you can use an inexpensive digital kitchen timer. Start by flying less time than you expect the battery to last. Check the mah returned to the battery by the charger at the end of the flight. Adjust your flight time until the charger is adding about 80% of the battery capacity.
