New FreeWing 80mm 12b 3658-2150kV

[Evan D]

I'm making a new discussion thread for the new FreeWing 80mm 12b 3658-2150kV that is in the Cougar and listed now for a few other 80mm FW jets. I just put one in my Gripen w/ TV. The old EDF was the stock FreeWing 80mm 9b 3658-1920Kv. It had the stock 100A ESC for both tests, only the EDF was changed.

Stock 1920kV-
EDF unit weight 352g
2400g thrust
98.28A
2257.4W

New 2150kV-
EDF unit weight 344g
Somewhere more than 2600g thrust. I used a 5kg scale and it pegged it bad
127.54A
2795.6W

Bottom line is that this is a killer set up. Maybe in more ways than one as it pulls almost 130A!


On the Motions site they claim 300g more thrust, only 5 more Amps and 100 more W (90A for the old fan and 95A for the new and 2000W for the old and 2100W for the new).

I also got two of the new 100A reversing ESCs but I have not installed one in anything yet. Also for comparison I have another Gripen w/ TV on a JF/ HET 1738kV 8S set up. It pulls 2765.8W!!!

Ill be adding this motor with a Hobbywing 130amp ESC to my A4 80mm. Thanks much for the work, i love this type of good stuff.

Worried about the Amps being pulled through the stock FW 100A ESC I swapped in a Turnigy Plush 120HV. With it, and everything else the same, I still peg my scale and am getting ONLY 111.68A and 2480.4W. It shows either one ESC is more efficient or the timing is different between them.

Hello,

can someone tell me where I can find information about the drive/motor 3658-2150Kv. I'm particularly interested in the recommended timing. How many degrees do you set this to?

Thanks

Hi

I thought these motors are 4 ore maybe 6 poles, so LO timing.
I fly all my jets with in runner motors with lo timing.
you can set timing to mid ore high but than amp draw goes UP....yes more power but lesser flying time

I have got 2 of this I`m putting in a F14... It have lower pitch than the 9B 1900kv. So I it probably gives more thrust in the low range.

I have installed the 2150s into my A-10. Oh yeh! Yes, could see/feel the difference. No regrets spending a few $$ for the upgrade.

Lon I have a set ready to go into my A10 and was wondering if you noticed a difference in flight times?

I have my timer set at 5min. I'll do 2-3 speed passes...when i land and check batteries 4.85-4.90 per cell
