Hello fpvmodels
Im flying multicopters two years ago.
I have building more than 15, and now I have two hexas, with Naza and Hoverfly pro plus gps both.
And I have some quads, with kk, kk2, openpilot clon and multiwii.
Also I have two tricopters, with Gopro and one quad clon dji f450 for fpv.
I have this frame for fpv:



And if you want, Ill like to test some motors between 800-1000 rpm/V and 45-70gr for 9x5, 10x4,5 or 11x4,7 mx.
If you dont have it, I use a Bumblebee chasis with four Leopards 2835 850rpm/v about 2 kg with gimbal and Naza that dont fly very well and motors end very hot.
Ill like to test some better motors, but in this case I dont know what can be better.

Thanks and regards

Thank you very much. I will be very glad to make a test of these motors.
But I don't find MT2814 KV770 on your website.
When will they be available ?

1.
SSA5 (0 min 17 sec)

2.
5aa1 (0 min 6 sec)

3.
Virgin Of the Poor - Bannimantap, Mysore, India (1 min 56 sec)


I am interested in testing out the T-Motor MT3506

I am already testing the MT4008s for a customer and have some test data available. I am quite interested in testing some of the other motors in the same or larger size range.

The rigs used for testing are my design WetHex and WetQuad for larger motors and a MiniQuad (18in) for smaller motors. I use APM / Arducopter, DJI Naza, DJI WKM, and MK flight controllers.

FWIW, I have been unable to validate test data provided by Tiger Motors with the MT4008. Current flyer is using APC 13x6.5 props (which seem to be a bit small) on 4s5000 packs. At 2.5kg 2500ma burned in 7min flight. At 3.5kg, 5000ma burned in 8 min. At 5.5kg, 5500ma burned in 3min.

I also do UAV fixed and rotary simulated and real-time airframe and flight controller testing for various customers, design and build multirotor and fixed wing AP/AV and UAS aircraft, and manufacture custom multicopters for AP/AV.

WetHex XL flight

Here are two flights with the WetHex XL.

This was the first flight at 2.5kg.

http://www.youtube.com/watch?v=_zwAgaVqpJI

And this was a test flight where 2 of the motors stalled resulting in a flip and crash. No damage. (strong frame) Cause of stall suspected to be ESC timing. The issue repeated once on different motors. Changed timing to High and there was no re-occurance. Have recently changed back to medium timing to try to repeat problem.

MT4008 motor stall (2 min 14 sec)
