Just a quick question.
Had a brainstorm the other day, might have hit my head, don't remember, who knows...

What are y'all using for on board power these days?

Last I flew, we were using 6? amp hour gel cells by Hobbico from Tower Hobbies. (The kind that powered the little Powerwheels Jeep your kid/grandkid rode in 20 years ago)

What kind of power capacity are folks using?

I was working my big a$$ Milwaukee 10" chop saw and saw how compact the 18v, 9 amp LiPo was, and how fast it charged on the included rapid charger and got to thinking 1, 2 or 3 of those on a semi-custom mount with built in voltage regulator would be right dandy in these birds, and available at the big orange box store if a replacement is needed in a hurry.

Just a thought. Please return to your regularly scheduled mayhem.


Like others I'm using two LiFePo4 batteries (10ah K2s). I've measured my current draw (Clearnav, Clearnav vario, Trig T21, Dittel FSG 2T) and it averages 1.26A in flight on a fresh charge. Other than a 1000K flight that lasted 9 hours, I've never had to switch batteries. After 3 years, the currently older K2 still measures about 9.2ah of capacity at full charge.
