Damn I'm hungry
@Snoopy1 Did some in shop testing of the Turnigy Graphene Panther 4S 75C 3000mah packs with the new SunnySky 2820 1100kv motor swinging a 12x6 ARES electric prop. All I can say is WOW. Glad I did a good balance job on the prop!
I would say almost 3X's the power of the stock Potenza 10 1350kv swinging a 11.5x4.5 electric prop. I think I could have gotten away keeping the packs 3S instead of 4S but like I said WOW! Ludacris power....Hovers 4pound 3ounce plane ( holding plane on wing tip) just under 1/3 throttle pulling 23amps for 389watts.


WOT burst produced 77 amps for 1141watts.
2/3 throttle produced 66 amps for 961watts ( about maximum for this motor).
1/2 throttle produced 51 amps for 758 watts.

This "Ain't ya momma's QQ300" going to be a real hoot I think :).

That is going to be a big difference, that is going to put a smile on your face for a while.

At last did something new today got my first plane prep and ready for the summer or the very first day it is possible to go flying. Checked the plane over new glow plug set the valves and cycled the battery and it is ok. So I am ready nice to do some work on a plane and not make sawdust. Just have to get the plane upstairs and start it up to make sure everything is really ready to go because if there is anything I cannot stand is to be fiddling with a plane when I should be flying.

Ok I have a few question to all on GSN. Did a battery check for the plane that is being ready to fly. Check the pack and would like your opinion. It’s a 2100 mAh battery and is 4 years old. As you can see from the test graphs on the screen each line represents a year so the best one the first year and today is lowest one in black. From the graphics you see how the battery is slowly losing power over time.
As you can see the pack has lost some voltage and some capacity the pack is down to 1850mAh about 13% loss but both cells still pretty equal but the both cells the AR value has climb about 8 points.
The question is would fly the pack for another year.

I change out my batteries every other year, no matter what they say. So my answer would be no I would not use them.
