You have massive nuts, running a 5 kw motor with exposed phases like, 3 mm from each other.

This one looks built wayy better than old CA80 models. I'm going to buy Rotomax 150cc next week. After seeing this, I might just spend some more and add this one as well.

[Duckula]

I was just waiting for that sc to short circuit and popped.. u r just lucky by 1mm dude..

[George]

Where did you buy it from mate, what’s the thrust ?

[ChequeredTuning]

I finally got round to retro fitting my H9 extra 27% with the 50cc Rotomax, the extra has done some hard yards and is used as a test hack now.

I got around 5amps no-load current at 40volts using my own DIY speed controller for my E-bike.
Going to use the Rotormax50cc to replace my old 2kw motor. I will most likely only push the new motor to 2.5Kw to 3kws.

If it were me trying this, I would have shorted out one of the phase leads to the gorgeous beast. Bless Hobby King for keeping these bad boys still in production!!

120 amps through unisolated wires millimeters apart on a carpet?

[BoneLaur]

hmm very good motor . how mutch it was ? .and what do you do with it ?

[WATAKAPISUBERRY]

can i use this setup for a mini sitdown scooter build?

[baronlocal]

galagios = necesita cutie fonica ( cu perete cu vata minerala sau termos lada frigorifica etc ) altfel duce la surzire prematura .
Turatie mare, vibratii puternice = folosit la vehicule scade speranta de viata .
Motor de masina de spalat da putere mare la turatie mica, fara perii si vibratii, silentios, ieftin,

[LowCostCncRetrofits]

bare connectors I cannot bare to watch :(

[MrGurkanify]

do you know how we can calculate the torque of your 50 cc engine ?
because your video shows no load perfs .
you use a turnigy servo tester for your throtle but can we use a scooter throtle ?

[Cyberdactyl]

I saw that too. With all that electronic paraphernalia, you would THINK he would know better.

But I guess money doesn't buy sense.

[TimTim]

Are you still running this rig? What's better out there now?

[grapefru]

HOLY FUCK I WAS SO SCARED WITH THOSE WIRES SO CLOSE TO EACHOTHER AND THE MOTOR MOVING AROUND LIKE THAT

[ddemko]

1. Where do I get the motor and esc
2. Where do I get that thing u use to adjust the speed of the motor

[DominoSixO]

Me looking the video: he put the hand of the motor, HOLY SH!T (big motor) :D

[joereyes]

what good are they if they don't have dual shaft for others good projects (The application is too limited.

[ZamanTurja]

how much thrust do u get from it, please mention the propeller configs
