Default Is 4350 mAh enough for F3A schedules

Hi

Thunder Power has new 4350 mAh 20C pack. I need a few extra grams on new plane, any pilots out there with experience on flying 4350 mAh packs in F3A competitions If applying the 80% rule should not draw more than 3500 mAh out of the packs, this is within my current power consumption, some comments please.

Regards
Burt

As long as you stay within the '80%' usage range, should be ok. I think several people were running those packs in FAI at the Nats.

Depends on the motor: In my experince it is OK on a Hacker 13 XL Comp (would be OK for a 14 as well) limit extra maneuvers. Figure 3000 mAH nominal/flight. Likely not feasible on an outrunner.

Andre, my P-09 flights using AXI/Dualsky are right at 3000 mah, slightly higher in windy conditions. APC 20.5x14 prop, 11 lb Integral. Don't understand your comment regarding outrunners likely not feasible.

Let me amend my imprecise statement.....it depends on the motor maximum watt capability and how one uses the available watts.

I used a 4350 mah Tanic pack (with Enerland Cells ...) last year in Masters with a Hacker C50-14XL, and a 21 X 14 APC prop on an 5 kg Integral, and I was drawing about 3000 mah to 3500 mah per flight.

The only complaint that I had was that after the pack had 75 to 100 flights on it I couldn't draw more than 3200 mah out of without risking have a cell go below 3 volts. In FAI there are 17 maneuvers versus 19 in Masters, so it should work fine, but I think you'll have to replace your packs at the end of the season though.
