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'm going for a cheap option so I was wondering if I could use a Hobby King 20A ESC 3A UBEC for this motor?
 anikeev 1548 points
Yes you can. This motor requires 18A in peak. I use it with 25A turnigy plush and everything is fine. Tested with 8, 10, 12 inches props and everything is OK.
 Usman 1 points
Alright and special thanks for the extra prop information, I was thinking about using a prop smaller than 10 inches.
Usman  1 points - 5/24/2016
Is it fine if I use a 10x4.7 propeller rather than the one suggested? If I can use it though, do I have to worry about anything?
 quitcherbitchen 83 points
That should be fine. Better smaller then larger. Rpms may go up slightly, but the amps probably wont.
 Usman 1 points
I appreciate that!

I have this exact motor and i have used it with a 11x4.7 prop with no problems, so you should be just fine

What size mount does it come with?
 meadowhay 1287 points
The 3 mounting hole in the rear plate are 3mm dia at 12mm radius if hat helps?
 anikeev 1548 points
Actually it has 3 mounting holes at approx 3mm diameter and 6 mounting holes at approx 6mm diameter. The bad news - you can NOT mount it X way. all mounting holes are Y way with 120 degrees between each 3mm and 6mm holes. I have X type mounting plate and use 3 of 4 plate holes. Motor is fixed by plastic clamps (zip ties). Works well for me.

I used an APC 11*7 (2 blade) prop and got 23A and 250W Are you guys getting similar results? The motor says max current is 18A. Does this mean I will burn up the motor fast? I do have a 25Amp ESC. This test was using HK-010 power tester Turnigy 2200mAh 25-35C battery * 12.4V (showing on the power tester) I'm asking because I put floats on the plane I have and I think it would be useful for takeoffs to have the extra oomph. Thanks!
 anikeev 1548 points
First of all, use epoxy glue where wires comes to motor coils. Because of vibrations it may loose contact and motor will stop. If you measure corrent on ESC - keep in mind that some current goes to internal ESC circuit and BEC on ESC (sometimes 1-2A). Motor sould not burn faster in this case. I use turnigy plush 25A with this and I have 12" props which requires even more current draw to spin up and everything is fine. You should not worry about it :)
 Motorbikebruno 3 points
Thanks! That's helpful to know. I will really only be using it for "emergency" power and take-offs from water/snow so I think cruising speed should be 18A or less. Thanks again!
Trey  1 points - 11/30/2015
Will this motor work for an ROV if I were to design a proper prop? Other suggestions would be greatly appreciated as well. Thanks!
 anikeev 1548 points
What does the ROV means? Is if underwater model or what? I can say, That this motor works fine with 8 inch props (can take-off 1.3 kg quad), but it's better to use 10, 11 or even 12 inch props.
 Trey 1 points
Yes, for an underwater submarine
 anikeev 1548 points
it requires some air to be chilled, So I don't think you can use it in ROV. You can try anyway. If you use small boat props with diameter about 3-4cm - it can work. But how will you make it waterproof? That's a good question :)
 SHIBU 11 points
This motor can run underwater with no problem, but the only thing is that it will rust
 Trey 1 points
That's great! My last question is if you have any suggestions for prop types and sizes for an underwater craft that would fit this motor?
 SHIBU 11 points
yes, try this prop PRODUCT ID: OR038-01408

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!
