First look at these monsters coming soon!
My dream of an airbot-hammock might just come true after all...
Here is the request for input on developing a new line of motors "tailored for UAV applications"

Double the amount, you forgot batteries. Such setup will not fly with a single 5000s/4/6s. Actual Ferdinand setup (97 minutes) contains batteries costing same as the rest of hardware (less electronics).
Anyway, is an futile exercise, simulation shows the results will be disappointing.
With 4x8s 5000mAh, weighting 4.5kg packs alone, and total 10kg AUW such setup will not be even able to take-off.
With 4x12s 5000mAh, weighting 6.6kg packs alone, total 12kg AUW will fly under half hour. And have capabilities for 4kg payload, which is lame, 6kg beer box was lifted with much less setup.
Thanks for that great thread Andy, it will be very interesting to see wha he gets out of those Tmotors.
8 of those motors at $280.00 = $2240.00 and 4 pairs of props at $390.00 a pair = 1560.00 = $3800.00 just for the motors and props, I can't even afford to build a quad with them - like to though.
Might try the HobbyKing or RCTimer ones, but does anybody other than Tmotor make props that actually fit them?
Props appear to be $320.00 to $390.00 a pair as well, although all are out of stock at Helidirect.
From 750 to 940 watts for the motors, look really nicely made (more like bicycle brushless).
With those 29" T-Motor CF props it would certainly make a very impressive looking if expensive QuadCopter.
Actually that could be right, might have missed a few decimal points.
1800watts and 20KG of thrust now that would be significant and about right for a 28" propeller.
Could probably fly an ultralight with one or two of them.
Good catch, Gary.
I only noted the price, as that was my major question when I first saw these. They have got to handle more than 180 watts, look at all that copper!
Hi Tobias,
That thrust and power consumption seems extremely light for that size of motor.
Their 4014 is 750 watts and can manage 3.2KG of thrust and is tiny in comparison to this motor.
I would expect something more like 1500-3000 watts and 10KG+ of thrust from something this size.
At 2 KG thrust it seems like it would barely be able to lift itself.
Tobias,
Sweet! Please share your results.
Very naiv promo, but see 1:16

I thnik "e-volo 200" *is not* supercritical design =)
F1P further thought especially true of Quadcopters.
For super critical systems any failure = total failure.
"Weakest link in the chain".
And, Robert, yes, recovery is NOT one of multicopters strong points.
Although a good case could be made for an Octocopter with dual systems each capable of operating 4 opposed motors in quadcopter fashion allowing that ample power / thrust could be generated to at least control descent.
Or a duodeca copter with 3 systems for that matter.
