Help!
What do you think about NEU Motors ?

Hi,

This is a general question, they're not cheap. What about quality? Ball bearings? Rotor? Thanks

Great motors! I have many small and one large one. All work great!

Neu motors are great motors. The only complaints I have are that it takes roughly two months from time of order to get one and the two times I have ordered motors both motors were configured incorrectly. One was sent without a gearbox and the other was sent with the wrong ratio in the gearbox. The one with the wrong ratio ended up being fine since I ordered a 5.3:1 and received a 6.7:1. It is in an electric glider so I just run a larger prop which is probably better anyways.

If it only took three to four weeks to get them I would have more of them.

How do they compare to less expensive motors in terms of performance and quality? Can you get the same bang for the buck elsewhere?

While I've never owned one, it's my understanding that Neu motors are the Lexus of eletric motors. They are all hand-wound and you get a snotload of power out of them. Someone correct me if I'm wrong of course.

Wonderful motors. I run well over 2200 watts through a 1515 series motor and am very happy with it. The motors are well liked by the high performance crowd.

With respect to "are they worth it." If you need to run a top efficiency motor then yes. You can push more watts through a good motor than a poor one since it is more efficient and thereby converts less of the energy into heat. It is the heat that will eventually kill whatever motor you are running. a 75% efficient motor will turn 25% of input energy to heat. A 90% efficient motor will convert 10% of it into heat. You are obviously much better off with the 90% efficient motor in applications where heat will be a factor.

I use them in a competition LMR gliders. My unlimited is running 6500 watts in a 1512 and holding up. Just spit the yoke off after it broke in half, but the motors are great.

Wonderfully efficient and gobs of power for the sizes. I have a fistful of them from 1105s to 1910 ORKs and all are top notch performers. Steve wouldn't use them if they weren't the best. He can't afford not to if he wants to win at F5b. Most of that group use Neus, btw.

So Neu's are great but if you had to settle for next best, what might it be?

It really depends on the application, you know. If you want to pack 1500 watts of power into the smallest and lightest motor you may need the Neu or something comparable, cost no object. Those F5B (hotliner) models are an example - but these are the extreme machines of RC flying. Competition LMR gliders are also extreme performance machines and need extreme performance motors.

But at the other end of the spectrum, old-fashioned freeflight models modified for RC and electric power will fly very nicely with 50% efficient brushed motors that can be bought for a couple of bucks apiece, or 65% efficient cheap no-name brushless motors. Yes, you'll be turning a third of the battery power into heat in the motor, but you may not care if the cheap motor gives you the performance and flight times you care about.

Hyperion and Scorpion motors (now the same, as Scorpion makes the Hyperion motors) are quite good, as Bob said. Hackers are good too. Also MP Jet's (hard to find in the USA). Many people are fans of the AXI motors as well.

Beware of most of the other brands of outrunners sold in the USA, including the ones with big brand names behind them - the ones I've investigated have all been no better than the cheap Turnigy motors, while costing two to three times as much. Total waste of money. Might as well use the Turnigy and pocket the difference in price.

I have aerobatic models with Scorpions and Hyperions and Hackers in them. I have lower performance models with cheap-n-nasty Turnigy motors in them, which perform quite adequately in those models.

However most Turnigy inrunners are terrible. Bad bearings, poor windings, horrible efficiency. Better to pay a bit more money and get a HET or ARC.

agree with the above post -

if you are competing to win you will need either Neu, Plettenberg, Kontronik, German Hacker (inrunner) or Lehner - any of these motors will put you into the top rankings provided your piloting skills are good enough

Your next tier down are the likes of Hyperion-Scorpion, Axi, Cyclone, Arc, HET etc.

after that you have Hobbycity

Bear in mind that Hobbycity will sell you a very usable working brushless motor with ca. 65 or 70% eff. for 12 or 15 bucks ... for "lo-fi" sport applications this is plenty good

The Hyperions and Scorpions aren't that much better in eff. although they are definitely better and more consistent in quality (bearing quality, manuf. tolerances, shaft strength, accuracy of Kv etc.)

these will cost you 3 times as much as the Turnigy Hobbycity stuff

and the top of the line German or American stuff will cost you 2 or 3 times as much again ie easily between 6 and 9 times as much as the Hobbycity stuff.

its your money you decide... the Turnigy stuff absolutely works fine... you just won't win any competitions with it

bb

PS MicroDan are great little outruners - pricey but worth it - however they have a very limited range

So what about ESCs?

So what about ESCs? Can you rank them in the same manner?
