Hobbyking just came with new large multirotor brushless motors.

 9235-100kv , that spins 30" props on 12S and capable of lifing 11kg each.

And for sure , these are cheap again, 1/3 of Tiger motor 10kg level, U11 motors.

Hobbyking selling needed props too..

nice find, had not seen these... looks like we will see some serious innovation in motors, especially costs during the next several months

Certainly puts the cost of a true heavy lift copter more in reach.

It will be very interesting to see how well these function in actual service.

Nice gear.  I wonder how the efficiency compares.  Might have to do some ecalcing!

Comment by Quadzimodo on August 28, 2014 at 1:42pm

Hugo - U8 100KVs with 29x9.5s on 6S is the most efficient configuration I have ever modeled (using ecalc, not real world).  I would not be surprised if this is as good as it gets at the moment.

Is that really a question Hugo ;-)

These motors can compete U11s for heavy lifting, but can not meet efficiency of U8s.

These are actually Hengli 9235-100kv Motors , which are rebranded , cloned as Turnigy.

here are few links :

I have all these motors with me, will post results when I get some time to test their efficiency.

Anybody got any links to multicopters that use this size of equipment? No interest in buying one,  but I sure am curious.

Steadidrone's QU4D X uses U8s
Comment by Mike T on August 28, 2014 at 5:27pm

honestly who is going to spent $160+ on motors with no prop data? Basically have NO Idea how these are going to perform. what other "serious" motor manufacturer does not list the prop data? honestly......

Comment by Tipu on August 28, 2014 at 6:52pm

@ Mike T

what actually you mean from prop data ?

if you are referring to performance data (current vs thrust) then y

ou must carefully read hobbyking and goodluckbuy link before comenting .

both pages have performance data.
