I'd like to know the Amps, voltage and rpm before take off (full charge) and then again after you land with WOT. Has there been any degradation over the time since you started using the FP F3A packs? If those packs can run that motor and prop for a season I'd probably go for them.
Perhaps the low timing holds the current down. Any idea what that might be in terms of degrees? I run 24 degrees on the JETI Spin.
I'm a flyer rather than an electrically-literate person I'm afraid, but, when I meet up with someone with the Wattmeter thingy,I/ll try to get those numbers....
Just from watching the flight performance,and seeing how many maH go back in,I haven't seen any degradation yet.
From memory,the CC85HV ESC has three timing optionslow, med, highdon't think actual degrees are quoted?
Certainly with my set-up, only the low timing is viable- with the other options,the motor will not throttle up.
Hi I flew with f3a05 so did a comparison between Dualsky 11t with cchv85 and FP evo Lites versus Hacker C50 and pro lites. Both planes using a 20.5 x14 APC prop
The dualsky was 6000 rpm and the Hacker 5600 RPM. There was approx 100 rpm drop on the Dualsky on a full power test at the end of the flight.
Thanks Nigel, the Flight Power pack looks like it is doing the job. Unfortunately we can't see the voltage under the peak current load. Maybe you could give us the same chart with just the voltage so the minimums can be seen.
I would expect that packs used on the Hacker would last a lot longer than those used on the 11T based on my experience but I may be wrong.
I've flown over 600 flights using the Hacker C50 and DualSky 12T and the only time I exceeded 65 Amps was when the C50 had a "slipped rotor" problem. I believe that pulled some extreme currents and degraded my three TP Prolite packs but four of the six 5s packs are still going. I had about 60 flights on a True RC pack, all on the 12T, and never saw voltages below 34 volts under peak loads. After a few flights on the 11T with currents in the high 70s, I saw minimum voltages below 33 volts which I consider bad for pack life. I don't have enough data to back this up so I guess I could sacrifice a pack and see how long it will last at these high currents. How old are your FPs used in this test? Have you seen any degradation since they were new? Thanks again for the good work.
