The ESC will change the way the motor sounds. Which one are you using?

I think you are right... the ESC settings may have been what's causing the weird sound. I have CC ICE 100 and when I changed the timing from Low to Normal, it seemed to have minimized that weird sound. I'm planning of getting the YEP 120 from HK for this so maybe I'll see next.

Thanks.
Rico.

That YEP 120 HV is what this other guy was using in his Chaos 600.

What size screws did you use to mount your motor? Mine didn't come with any

mine nither came with any scews bummer?
I will get to assembly soon just on another project my srimok 90 N but still need some tweaking to do.
I figure it should work fine I compared it to the Hacker Tornado and its alomst identical.

Get some M4x10mm socket cap screws from Home Depot for less than $2. Depending on how thick your motor mount is, you might also need an M4 flat washer to prevent the screws from contacting the armature.

I plan to stretch Align 600e or ESP to 690 blades, 12S using YEP 120A HV, Turnigy SK3T 700, Power HD 1212 servos on cyclics, gyro Tarot ZYX, RJX FBL head. mod 1 550/600pro/700 main gear, 700 tail boom and TT.

I already have motor and regulator. Did not test it yet. I have ordered 690 RJX FBL blades.

I am not sure yet what, lipos and tail servo I'll use.

Any advice welcome.

In general I wanted to use cheap but reliable components. Second hand ESP with 3 6S 4900 Ah 25C lipos was 1/2 a price of 600 PRO combo.

I have done around 200 flights with 600e FBL TT 12S using Power HD 1209 servos and was satisfied with their performace.

I bought 1212 servos for stretch because 1209 were on backorder. 1212 are little stronger but also bit slower...

I am interested how you get on with the stretch. I am about to do the same using the same but I won't be doing anything for a while.

YEP 120HV and SK3 4962-480Kv = awesome

Did a few test spool-ups all the way to 100% throttle (no main blades). Motor runs smooth and appears to create lots of power. Can't wait to put this in the air.

[bwijk]

here is the motor in a hex50. The heli is a design made by a friend of mine.

[DVUSHELI]

I found some M4x10's at the hardware store and even with a split washer, they can be too long depending on how you orientate your motor. So if you can find M4x8, you may be better off.

Thanks bwijk.
That answers the question about the motor!
Now to see how good the ESC is.....

[bwijk]

Only thing i do not trust is the durabilaty off those tiny bearings in the motor...

[karl k]

Four flights with the motor in the E640 with 620mm blades.
The first two flight had the motor running a little hot. I changed the timing to low from medium and the heat went away.
The motor is barely warm after flying. Plenty of power on 12s governed to 80%

[karl k]

Video of the flight. I'm no 3d master, but you can hear it on punch out.

[DVUSHELI]

Great video and flying, gotta tell the cameraman to stop with all the talking so we can hear the heli.

[bwijk]

I would off told the cameraman to shut up.

[rallyant]

Any more news on this motor?

I found a videoo of a 700 flying one, asked him what he thought and he said good on the 600 but burnt one out in the 700.

[Stolla]

I did a rewind on it u can read about it in the rewinding forum, the small bearings are only one end but not as bad as it seems as it has 2 double stacked. As for burning out has to be fault with the specific motor, motor stator is same size 4035 as scorpion. Dunno size of hacker turnado but looks almost like an exact copy. If youre not after absolute max power this is a good motor. Certainly good value

[rallyant]

You have renewed my interest in one !
Might put my HK3 4035-530kv up for sake and get one?
