I have problem with my H3126. It gets very hot after 5 minuites hovering in normal. My timing is 6 (I tried also 15 and 18), PWM 14kHz. My ESC is YEP 100A and I programmed it by programming card. My heli is Tarot 500 ESP (copy of T-rex 500ESP with belt). Does anyone have any ideas what could be wrong?
I use the motor in Funjet Ultra with 6S 2200mAh Nanotech 25-50C.
Graupner Speed 5,5 x 5,5 gives ~65A, ~1300W.
TGS 7x6 gives ~85A, ~1750W.
TGS is a bit too much so I didn't even bother flying since I am pretty sure I would burn the motor. With graupner the motor runs quite warm although it should handle more than 1300W. I have done only 3 flight yet, so far so good, I just hope that it wont burn in the air.
I tested the motor some more.
APC Sport 6,5x6,5 ~90A ~1700W
The nanotech are not up to the task, dropping to 3,16V per cell
APC 6x5,5 E ~75A ~1500W
This appears to the optimum so far, good performance and
the motor stays cool after 4min run in Funjet Ultra.

1 thumbs up!
What does this motor actually weigh?
It's really annoying that HK can't seem to get either the weights or KV of many motors right in their specs...
such a nice looking motor for such a unbeatable price. no doubt this is gonna be a winner

What more could you ask for? Great look, Great Price, and Great performance. Currently running a 4s batt, 8x6 prop, pulling 77amps @ 998 watts. I will soon switch to a 100amp esc and 5s battery. Highly reccomended for a large/fast plane. I have a SR-71 that is 5 feet nose to tail and it screams on the current 4s setup.
