hexTronik DT750 Brushless Outrunner 750kv

hexTronik DT750 Brushless Outrunner 750kv

Looks can be deceiving. This outrunner is around twice the size of a towerpro bell motor, and swings a much larger prop. Its the motor used on some of Art-techs new plane kits, which is testiment to its durability, ease of use and quality.
The DT700 will swing an 11x4.7 SF prop nicely, to produce more than 900g of thrust.
Its great for larger GWS foamies or parkfly planes.

Required Voltage: 11.1v
Suggested Battery Capacity: 1300mAh +
Suggested Prop: 11x3.8 or 11x4.7
Max current draw: 18A (with 11x4.7 prop)
Max thrust: 1000g+
No Load Current: 1.4A
Shaft: 4M (perfectly suited to Towerpor/GWS SF Slow Fly props)
Weight: 78g
Diameter: 41mm
Overall length: 77mm
Kv: 750rpm/v
Comes with mount as shown in Image

Test Report.
We used the DAT700 outrunner to power the an Art-tech Pitts. Run with a 1300mAh 3S1P 20C pack, 18A BESC and 1147 GWS/Towerpro prop, the Art-tech pitts ran nicely. Excellent climb rate, though not hoverable, and with 13minute flight times or more, we were very impressed.
A very efficient outrunner for slower flying models of up to .15 size.

I checked the manual for my ESC and it says the throttle push rod is not in its lowest position. I am not sure what that means. Please Respond

which ESC you are using?

How do you set up this motor. I tried to attach the motor and speed control with wire connectors, but when I turn the motor on and use my remote to control the motor, the motor is giving off an alarm sound. I do not know what the problem is. Please help.

You have to set throttle range for your ESC. To do that, 1) Turn on your Transmitter 2) Put your throttle stick to the full (usually at the top) 3) Turn on your ESC 4) After hearing the initial tone, wait for two beepa (depends on your ESC, see your ESC catalog) 5) Right after the beeps, put down your throttle stick to zero (usually, all the way to the bottom). 6) ESC will beep a long tone (depends on which ESC you are using). Thts it.. :-)

It does work, but you have to use smaller props. Watch the maximum current draw. It works perfect for me with a 4S and 9x3.8 props

I use 3 motors like this on my Y3 tricopter with 1147 props and 4 cell/5000mA battery and until now everything works fine. You should watch the motor temp for beginning.Hope this help's you.

50 thumbs up!
Because of the price and reasonably accurate description, I'll give it five stars. Modest 8mm (!) bearing tube and bearings don't sound all that great, but the power efficiency is pretty darn good if you can carry the nearly 3oz weight.

For example, a 10x4.7 APC SF plus TP 1320 3S produced about 34oz thrust using 13.96 amps. Both Drive Calculator and Badcock's web page put this as 84-86pcnt efficient. 11x4.7 APC Sf produced over 40oz thrust for a bit over 17 amps. That's still very good efficiency!

Again, if the weight and 4mm screw shaft don't scare you, it will definitely pump out the stuff even if it sounds a bit like a coffee grinder. Added bonus: very nice motor mount that will work great with your MicroDan.

This are the results of my test, measured with my eagel tree:

11 x 7 GWS HD (not the slowfly version)
peak: about 13.5 A
after 20 sec about: 12.0 A
on 3 S with on 10.5V

11 x 4,7 GWS
peak: about 15.0 A
after 20 sec about: 13.0 A
on 3 S with on 10.4V

12 x 6 GWS HD (not the slowfly version)
peak: about 15.0 A
after 20 sec about: 13.0 A
on 3 S with on 10.4V

I couldn't measure trust but from my feeling the trust with 11x4,7 and the 12x6 are nearly the same. The speed with the 12x6 is higher. This will be my choice.

I will put the motor into my selfmade Extra with about 700g, I hope it is a good choice.

I think the motor could spin a bigger prop, next time I try the GWS 12x8 HD and the GWS 11x8 RS.

I don't no if I have get a lower Kv version. I read in the rcforum about measurements which are close to Davids.

Wow. This motor is such a great value. It pushes my 2lb Das Ugly Stik around with authority. I got 34oz thrust with 11.1v 20c 1600 Lipoly and 11X7 SF APC prop. This puts me into larger RC planes at a modest cost.

I think Dave got a dodgy motor because mine doesn't make any grinding noises at all. I don't know if I'd call it completely silent but it's no louder than any other outrunner of this size. And while I haven't tested my motor yet I do trust Dave's numbers post above. So, it's cheap, quiet and very efficient. And all for under $11. A bona fide bargain in my book.

Bought this for my Lanier Fokker biplane.
It is a good motor for this slow-flying WWI bird.
With this motor and APC 10*3.8 prop., the Longmax 1300 3S Lipo doesn't get hot and not even warm after 6-7minutes flight.
For this price, I like it very much!
