Multirotor motors around $15

Tried the NTMs, but using the reverse shaft mount was just not good. The quality control is very bad and I get vibration whenever I fly. I still do not know how to reverse the motor on the NTMs- if anyone has instructions I would appreciate it. I'm outgrowing the DT750s and would like to try some other 750 kV motors that aren't ridiculously expensive $30 each. Any suggestions?

@ Mike, dtm and git: Thanks for the suggestion- I will try to find them although I might have to prop down (11*4.7) with 750 kv atm if I do end up using those motors.

Multor: I'm referring to the direction of the shaft, not the way it's spinning. Thanks for the advice anyway.

4s was overkill for my application since I am running 1147 props. Thanks for the tip though.

Ken sells these at quadroufo. Use them on the quads I don't want to spend a ton of money in but still lift about 1.2kg on 3s. They are similar to rctimer so you may get a bad one every now and then but for $12 each and here in the states I don't know of anything cheaper.

I have 4 NTMs but never tried it.

And I guess I vote for sunnysky too. If you're gonna buy those sunnyskys, DO NOT buy from goodluckbuy. Go to HiModel.com instead.

Yes some motors you can reverse the shaft I have the sunnysky motors 980KV with out a shaft sticking out either side just using the bolt on prop adapter. much better then the clamp kind IMO you can also get the same motor with a shaft and you can place it sticking out the top or bottom

Did he have to dremel his own C-clip slot?

No, AFAIK nothing like drill, dremel or sort of. He said he just 'removed the C-clip and put it back'.

Yes a lot of the motors will have a set screw on the drum side and the shaft will have 2 slits for the c clip so that you can reverse it...
