Hi Felipe, This motor doesn't hold up well with a 3S LiPo. The 10.5VDC rating puts it just under the range for 3S. I had one that I tried to run on a 3S and it smoked with no warning. It was running fine one minute and then completely burned out in just a few seconds. It does run well on 2S and gives almost 450g thrust. If you're looking for a powerful 3S motor around 25g, have a look at the HK 2614 (PRODUCT ID: HK2614-2000). Cheers, EA!
Ok guys I gathered a litlle data. I put in my review, but I see it didnt post. I really like this motor. I use 2cell set ups on all my park fly planes. On airscrew 6.5x4 prop 200 grams thrust. APC 6x4 100 grams thrust. 6x5.5 170 grams thrust. APC 7x5 280 grams thrust. APC 7X4 SF, 300 grams thrust. APC 8x3.8SF 350 grams thrust. These are the only props I got to test so far, I might try more. But for such a light motor and 2 cells only, I think thats quite respectable. It pushes my scratch build 345 gram FT FunBat very well. Maybe with 3 cell and 7x4 ....7x5 slow fly prop, it might be close to 450, 500 grams? The 3mm shaft has not bent after several hits, I do have it as a pusher.but I have broken 1 prop already, and no damage. Great motor! !
Hi Buddy, Thanks for providing some solid data. It's a big help for the people trying to decide on which motor to pick for a new plane. I would avoid trying to get more power by going to 3S, as they tend to overheat and burn out very easily on 3S. Just play around with different props until you find the best combination. Cheers, EA!
By the way, it flies great in my miniskywalker with just the 1550kv version at 6x4. I get almost unlimited verticals. So i think it'll be a winner for the 2050. But the this motor is probably a rewired version of 1550 so it'll get hotter..
Hi Cristian, It wouldn't be simple to reverse the shaft on this motor because of the little circlip you see in the photo at the end of the shaft. With the reversed shaft you won't have a circlip groove in that location to hold the motor together. You would be better off buying a similar motor already configured the way you want it. Cheers, EA!
Hey christian, I just ordered this motor. What I do to reverse motor shafts is , just take a dremel or a file and make a flat spot about 2mm from shaft end. Take grub screw and clip off,then push the shaft until the flat spot lines up with the grubscrew hole. Reinstall grubscrew, reinstall the little washer by where the clip came off and instead of the clip install this 3mm collar (hobbyking #016-00302x10) to hold it in place. Now its reversed, and didnt have to take the motor apart, just that simple. Hope this helps.
Hi Polycapman, You could use this on the scratch build f-22 and it would have enough power to fly the plane, but it wouldn't be extremely fast. If you're a beginner/intermediate pilot it would be fast enough. Use a 6x4 or 6x5 prop with a prop-saver. The f-22 doesn't have landing gear, so you want the prop to be able to "give" if it catches the ground on landing. Cheers, EA!
Hi Polycapman, This motor could work on the Radjet, but it's a lower kV than the stock motor that comes on the plane. You would have to use a slightly longer prop and a bigger ESC than the ones that come with the plane. This motor could work on the Parkjet, but you would need a longer prop as the kV is lower than the motor that come with the plane. Cheers, EA!
Hi Sean, This motor will fly the wing okay, but it won't be screaming fast. The 550g thrust spec shown above is in someone's dreams. I have yet to see more than 400g-450g having tried various props on this motor. You might to have a look at the HK D2822/14-1450kv (PRODUCT ID: D2822-141450). Combined with a 3S LiPo, it has been bullet-proof for me. It has heaps of power and takes bounce after bounce without failing. It weighs more than this motor, but the additional power is worth it. Cheers, EA!
Hi Sean, Thanks for the credit. For some reason I thought your question was asking about a motor for a flying wing. If it's for a 3D plane, it's even more important that you have plenty of thrust. The general rule is you want thrust equal to twice the weight so that plane will hover at 1/2 throttle. Either of the 2 motors I mentioned will work fine. Cheers, EA!
Hi laika, This motor is nowhere close to having the power you need for a 500g park jet, as the max thrust I've been able to get from this motor is around 450g. The general rule for aerobatics is you want a motor with at least 50 percent more thrust than your model weight for any serious aerobatics, especially verticals. 3D flyers usually want double thrust to weight ratio. Cheers, EA!
Nope, it would make the parkjet fly very scale like. This motor can generate around 350g of thrust on 3S, 7x4 prop. That is the best setup you can get with this motor, otherwise it will burn out (had that happen with a 8x4 prop_
Hi Oliver, Don't worry, I'm not stalking you. You just happen to be posting questions on motors I've recently purchased, so your questions pop up automatically. Regarding your question, this is not a good choice for the Bixler2, as it just doesn't produce quite enough thrust and it is too short to fit properly. The Bixler2 would fly with this motor, but wouldn't have enough thrust for aerobatic capability. The great thing about the Bixler and Bixler2 is that you can learn to fly as a complete novice and then move on to basic aerobatics. Cheers, EA
Hi all, I bought this baby, I will use it with mini skywalker with a 6x4 pusher propeller. I am mostly interested in slow flying in a small field as the field options are limited around here. I am in a dilemma, should I use a 2S battery or 3S battery. I know with 2S it will be slower. Any advise is appreciated. Best, eertan
Hi Ertan, Go with the 2S option, as these motors fry in a blink if you run a 3S and push full throttle. You'll get better slow-fly performance and reliability with a 2S and something like a 8x4 prop. Cheers, EA
Hi, I'm thinking about using this motor with a two cell 2200mah and a 7035 prop for the hobbyking trainer kit, IDOL. Its got an 890mm wingspan, and will weigh about 450g ready to fly. Will it be to much power for a small trainer???
With a 3S lipo this motor c20 2050kv can produce ~400g of thrust with a 7 by 4 prop. But it gets burning hot after 30 sec of full throttle. With a 2S it produces around 300g of thrust, doesn't get that hot. This should be enough for your trainer, maybe a bit under powered (I prefer 1:1 thrust to weight ratios at minimal!)
Hi mate! That setup sounds fine! The 5x3 doesn't pull that many amps on full throttle anyways... I would recommend using 22 AWG servo wires for connecting the motor to the ESC, that way you can take the wings off for transport... These are the wires I use: PRODUCT ID: AM-2004-45 Good luck! Anything else just ask!
With various combinations of 2s and 3s batteries plus apc 7x5 and 8x4 props I am getting only about half the typical thrust I see in the many reviews. I am using a HK 18 amp esc. Even using 8x4 and 3s, drawing 13 amps for just long enough to get a reading, thrust is only 370 grams. What could be the problem???
Hi. The recommended propeller for max performance with this motor is the 7035 (GWS). With it and a 3s battery you would get the max performance out of it. Which is (according to the products specs) 552 g. The problem is with the props you're using, only with the recommended one will you get the most out of it.
Hi Louis! I have this motor for my mini skywalker, I use a 5x3 prop and a 3mm prop saver. They are both available from HobbyKing! If you are going to be flying fpv with the mini skywalker I would recommend a Turnigy 1000mah 3cell, if you are not flying fpv, get a slightly heavier 1300mah 3cell ... Hope I have helped mate :D
Hi pal, thanks! That's very informative. I still left with some TGS5x5 props, do you think I can fly with that? Likely I won't be fitting FPV, just too heavy for that little thing. Just normal maiden flying weekend. What's your experience in flying this walker? Was it fast, easy to fly and control? Any flying tips for me? My setup will soon be done... Hope I can fly like a bird. Cheers.
Hi again! I haven't gotten around to the maiden flight with mine yet- just too windy in Scotland :D But I have seen many people fly these with the C20's and tonnes of FPV gear and have an absolute blast, so don't be afraid to put some FPV equipment on it :) If the prop fits without s****ing the fuselage you should be fine... -Al
you can, but the plane should weigh around 200-350g only.

They got the prop right but the cell count wrong. Efficiency is poor 3S (<70pcnt) but jumps to 80pcnt 2S: 12,303 rpm @ 7.52 volts & 7.37 amps. Kv is too high for 8040 HD and efficiency suffers. 3S is good with 5043 prop. Numbers okay for the motor weight.

Use this motor in my F-22, Depron scratch build. And works ok. Measured the power draw with the recommended propeller and this was a little high power draw, in static. Used the wats-up meter. But the motor runs good, and have to see how long it lasts with the recommended propeller. No vibrations in the motor.

I use this motor on my homemade depron racer. It is turned by the TURNIGY Plush 12amp on Zippy-H 1200mAh 3s battery and APC 4.54.1 propeller. The setup is drawing 11.2Amp static but the motor comes down only slight warm after flight. I am experiencing sync loss sometimes with this setup because of the ESC/Motor combination, but havent tried with other ESCs. The shaft is a bit soft material.
