104,3 peak A with a Kontronic Jazz 55-10-32 esc. in my Ion-X

[PDC]

Made a test flight today with my Ion-X and my new FlightPower 103700ma EVO 20 batteries.

Have been testing the Kontronic Jazz 55-10-32 esc. on the Ion-X for some flights now without any problems, so would like to see what kind of Amps it handles. Nice to discover that I am pulling over 100A on this esc with no problems so far.

The configuration can be seen on the attached FDR graph.

Haven't measured any temperatures yet, but everything is nice cold, maybe partly because of the cold weather here right now, just above the freezing point.

I use a 52T secondary gear and gets 1860RPM on the head with zero pitch, expect that to be a little higher at warmer temperatures.

There is a huge difference in performance with these new FlightPower batteries compared to the Tronic I used before, so with this light setup (4.8kg) 10S gives good performance.

Peak Amp = 104,3
Peak Watt = 3316,2

dang , you sure dump those packs huh? is that with the hacker motor ? hey , at the 42 second big peak , were you going into a fast flip with alot of collective ? if thats a Hacker motor , cool

Glad to hear you are liking the packs Paul. We are really liking them as well!!

Cool info, thank you for the graph!!

:D These FlightPower batteries are just the best, must have more more more.

If they perform that good at temperatures just above the freezing point I can´t wait to see how they performs when it gets a little warmer outside.

It is the NEU 1521 1.5Y motor I use. When I used the Tronic cells I needed to have more battery mass with me up, plus a heavy and expensive Schulze esc. Making the ship a little in the heavy end resulting in everything was stressed to the limit.
The power was great with 12S, but the stress and high rpm on the NEU motor was a little too much at the same time as there was problems with the 60T secondary gear.

With this light weight setup, I have saved a lot of mass, partly compensating for the power loss of having only 10S. But the heli feels lighter in the air, guess it is because it actually is lighter now :)

Also the voltage is kept better with these EVO 20 cells, so 10S EVO 20 might give more or less the same voltage as 11S with my Tronic cells when loaded.

So a light weight setup with high performance battery´s is something i warmly can recommend, as a light heli always handles better and gives less problems overall.

You see the good circle all started with the right high performance lightweight battery?

Maybe a 50T secondary gear will give just that litte extra headspeed to make the heli really rock during cold weather operation. Must try it.

Not sure what I did when I hit that 104A peak. But guess I can pull more if I dial up the pitch even more and pull harder in the sticks :D

Would like to try a 12S setup again on the Ion-X, but it must be with a motor with a little lower KV rating. Until then, I now have a setup that works good and are expected to be reliable.

PS. almost forgot, maybe part of the story that the Jazz controller can handle these loads is that I run it at 100% throttle curve, which is what any controller likes the most.
