RE: Your thoughts after reading JR 12X manual
The 12X manual does leave something to be desired. It's not horrible, but they missed some obvious errors (like the tension adjustments).
As for the battery, I've continued to enjoy good performance from mine. After a charge session with the stock charger my battery is usually at 11.2 volts. It remains above 10 volts for quite a few flights- four to five. I don't charge until it's at 9.6v or less and have flown down to 9.4v. Overall, I do wish we had an approved lithium battery option. I do prefer the charge routine and power density of lithium. Horizon should give us this option.
