Recomiendo a los aeromodelistas que practican Racer F1 si compran este motor , que desmonte el rotor y aseguren las bobinas del estator con barniz dielectrico para bobinados (secado en estufa o secado al aire) , es la forma de asegurar que no les pase lo que me paso a mi

Despues de montar este motor sobre mi Invictus , al cuarto vuelo empezo el motor a efectuar ruidos extrañ*os (cuatro vuelos en dos meses) parandose el motor en vuelo. al desmontar el motor se comprueba que los hilos del estator se han salido de las bobinas y el rotor se ha blocado al pillar los hilos de las bobinas. Se comprueba la falta de barniz en las bobinas , con las vibraciones normales del motor (este motor con lipo 3S gira a 15.400 rpm ) las espiras se salen de su alojamiento ,destruyendo ell motor. El fabricante debe tener en cuenta que un poco de barniz en las bobinas las inmovilizan y aseguran que las espiras del bobinado no se salgan de su alojamiento , 0,2$ aseguran un motor ok. Espero que esto sirva para mejorar el producto

Just bought one for my pulse 15e. 70amp esc HK.3s 5000mah35c battery. 12x8apc prop. Pulls 63 amps 759 watts WOT. Checking with my 4 cells next. Without a doubt kills my buds even at 3/4 lead I will beat them down! Super fast! Only buy if you like to go FAST!!! Switching to 10x10 and 8x8 next readings too.

Second test 4s3700c65, 10x10prop, pulls 84amps 1259 watts wot. Beyond Fast! Motor is not rated for this don't use with 4s. 10x10 with 3s5100c50, 52amps 650 watts, works great. 8x8 was good numbers with 4s 68 amps 750 watts wot, but not enough prop for plane to fly right. next props 10x8,11x8,12x8.

10x7 apc prop, 4s3700c65, pulls 68 amps 1050 watts. Crazy fast pulse 15e! 12x4 apc prop, 4s3700c65 pulls 68 amps 1000 watts. night visionaire unlimited 3d! 12x8 apc prop, 4s3700c65 pulls 90 amps 1350 watts. Do Not Even Try! Way beyond limits!

this motor was designed specificly for the NMPRA EF1 racing class although other props can be used the 8X8 on 4s is what it was designed around.

I dont understand this is a 930w Motor and HK only suggests 8by 8 prop that can only give 560W? Come on HK do some work!

In this specific situation the max power is achieved with the same size propeller but there a lot of difference between using 3S or 4S battery

this motor was designed specificly for the NMPRA EF1 racing class although other props can be used the 8X8 on 4s is what it was designed around. that's why its only 560w due to the restrictions on the racing class

Dear all, I am very happy with this motor. We did a comparison with two other official approved EF1 motors. They all three had exact the same performance only this motor cost the half the price!!

just got two of the Generation 2 motors and was at the EF1 race at Old Julian Airport last weekend. I had not mounted or tested these motors but, a friends motor died in his racer and we took one of the new motors and put it in his Wagner Solution and it preformed very well for the 8 races it flew. I plan on putting the other one in my Shoestring and hopefully they will have more of these motors available soon. The only thing they could do better is to increase the bullet connectors size from 3.5mm to 4.0mm. The silicon insulation on the motor wires and the small flutes on the back of the motor case to keep the wires separated is a good quality touch.

WELL I HAVE ORDERED 2 OF THESE for the invictus planes , along with yep 80 amp escs . they are a very smooth running motor , combined with the nano tech 2650 mah 30-70c 4s batteries they pull 1038 watts peak and settle at about 61 amps 960 watts with the rec 8x8 apc props . seem well balanced with no resonance on any throttle position .

I don't know where these guys get their prop data from...mine benched 50A with apc8x8 using 3300 4s 40C turnigy lipo. run thru a plush 60 esc. I tried to get close to the max amp level of 65 with a 5S 2700mah nanotech. at 80 percent throttle I saw 63 amps and shut it down. after only 2 small bursts on the bench, right out of the box, there was a little bearing play on the motor. other than that, it looks very beefy. can is 38mm diameter.

finally got it installed in my NMPRA pogo and test flew. was less than impressed with the stardard ef1 setup 4cell 65C nano, plush60, and 8x8 APC prop it only pulls 49-50 amps 720watts at WOT. my model is 3.3lbs all up. this motor is rated to 65A on paper. im thinking about putting a 5 cell 2700mah and see what happens. im feeling fearless with a separate ubec powering my rx and servos, hehe.
