Anyone looking to really push this motor should look at the 42-50-650 SK.
It uses about 10-15amps less (about60-65) than the 42-50-700 on 5S 14 x 8.5 apc. I have been running this motor with great success and have built three other planes for friends with the same power set-up. Remember to fly with common sence and not keep the motor pinned , remember to give it a break to cool down the odd time. I fly at 1/2 to 2/3 throttle with full throttle uplines and get 10-12 min.

I always run with my throttle trimmed up alittle bit to keep the motor running, giving quick throttle response from start with no stutter. . No problem after that. Over 70 flight on 5s 5000 at about 1260 watts. Nice motor

Just got this motor, set it all up (with a Hextronik HXT80 and a Zippy 2200 4S 14.8v). opening up the throttle a bit causes it to run rough and vibrate for a short time, until throttle is increased (say up past 25%), then it runs smoothly. This ONLY happens on start up, and for a short period... Anyone have any ideas? Thanks!

tried all 3 settings (I believe it should be the 12 pole and for outrunner motors setting. Brake is off, cutoff is soft... After reading about loose magnets, could this be the problem of roughness/vibration on startup? Thanks!

Wasn't the motor at all, it was the esc that was faulty. motor runs great with new ESC...

I purchased this motor and it ran well during ground tests.Prior to the first flight,during a engine runup, 4 magnets came loose inside the motor causing a screaching noise. I have shippped it back to hobbycity for a replacement(RMA #7985-290367)... it was almost a total waste since the shipping was nearly as much as the cost of the motor! It would have been nice if hobbycity could accept a e-mail photo to verify the Defect instead of me having to spend the money to ship it back only to realize the motor is truly defective. I will report back when the new motor arrives...we shall see!

What would be a good ESC (that also powers Servos) for this motor?

One of our four threw magnets tonight just running up on the ground.
ALL THREE of our larger 50-65's threw their magnets and are now useless paperweights. definitely a problem with some of these motors.

Hi, Peter from Australia, i purchased three of these motors, two of them did the same as David (4/21/09) motors seized due to magnets coming loose. Not game to use the third one, but all other products I have purchased, no problems at all and all at a fantastic price.

Hi Peter,
I originally tried to glue the magnets per Dragevo's recommendations, but after the repair, the motor was still inoperative. Some other customer rebuilt his loose magnets and they subsequently came loose again! So I packed mine up and returned it to Hobby King for replacement under warranty. All my other Turnigy brushless outrunner motors have never given me any trouble so the loose magnets may be limited to the 4250-700 motor.

I suggest medium CA, clean bell & magnets with thinner or equiv. - before installing. To find the correct space you need to know the bell-circumference & the width of all the magnets combined. Next, subtract 'magnet-width number' from circumference number. Then, divide this number by # of gaps/space. Use a piece of ply, sheet metal etc, of the correct thickness - to keep the distance while the glue cures. If in doubt, post a Q in the forum - I or someone else will help you further. GL. : )

Thanks for your reply. I do have two questions however:
1. What grade of CYA glue (instant/medium/heavy)should I use?
2. How do I install the magnets with the correct equal space
between them (overcome their attraction to each other)

My Turnigy C4250-700 ran fine for about 2 flights and then died. Disassembly revealed that all the magnets were loose. Same story in other discussion so
it appears that this is a quality control issue. Although it is still under warranty, the cost of returning it is high enough that I would like to repair it by reinstalling the magnets. What is the procedure for doing this and what adhesive should be used? Appreciate any advice.

Very dissapointed. On 4s Hex 4000mah with Turnigy 60A ESC, only generates 368 Watts at 23.6 Amps with a 11*6JXF Wooden Prop. Flew my 40 size trainer well for 5 flights at average flight time of 8 min. During sixth flight during take off the motor siezed completely and loosened a number of magnets. Obviously a problem with either the workmanship or quality of the glue used. Note sure if it is worth sending back to Hobby King due to shipping charge

I recently bought 3 of these motors and had the same problem with 2 of them: they just seized. they were replaced by unitedhobbies but it cost me 2x $8.00 of postage... Nevertheless, I have equiped 3 planes with the 42-50 700kv and they are normally very good. I run them with 4400mah 4s, 60a esc and 13x8 props with average flying time of 18 minutes and around 580 watts.

As far as cell counts, I've gotten 70 or more flights with mine running on 5 cell with an 11x8 prop, 41 amps, 710 watts. Granted, I bought mine back when it was labeled under the HXT name, but it's the same motor. I tested mine under no load with a tach & came up with that it was actually 670KV. I've pushed it pretty hard & haven't had a failure yet. I have tried a 6 cell combination with it using a 10x7 prop, (38 amps, 790 watts) but I'm pretty sure the bearings didn't like the really high RPM that it was producing, it made a unpleasant sound. With a 10x8 on 6 cell it was in the range of getting hot enough that you could start to smell the windings in the motor.
Personally I ignore the watt ratings of the motor, & just pay attention to the max amps it can handle. Amps are amps whether you're pushing 720 watts on 5 cell or 800 watts on 6 cell.

Yes Frank. It will be:
1) Original rotor-side adaptor + X-mount + bolts set
***********hobbycity****/hobbycity/store/uh_viewItem.asp?idProduct=7078&Product_Name=TURNIGY__42-XX_series_Spare_accessory_pack
2) Stator-side adaptor

***********hobbycity****/hobbycity/store/uh_viewItem.asp?idProduct=5673&Product_Name=Shaft_adapter_to_suit_5.0mm_motor_shaft_(collet)
But remember - in #1) set, four black bolts are trash. We allways must to replace them with straight ones. Moreover, it is very advisable to trim bolt-head-hollows in the adaptors body to flat bottoms and slightly expand their diameters for bolt-heads.

Doug, I've run mine on a 13 x 6 and 4s (3250 mah) and after a few seconds the readings on my e-logger were 15v, 36.5A and 8,900 rpm. So pretty close to the quoted max efficiency current. I'd rate the motor more equivalent to a 52-60 four stroke than a 32 two stroke.

Hi, Peter from Australia, i am using this motor in both an Ultra Stik and Diamonte with a 3s 4900, 13x6.5 prop pulling 35 amps and the Ultra Stik goes vertical - good combo

I have been running one in my Yak with a 5s 5000mah producing 1260 watts at 70 amps peak (static) Keep in mind that your values will change in the air and reduce by about 10-15%.
This motor pulls my Yak around for 10 min with SICK verticle. Gauranteed no BS. Flyer88

Although I'm only giving it 4 stars, it really deserves 5 stars for value. Overall quality is quite good. However, mine started making bad noises after a few flights. I discovered that the grub screw holding the end bell to the shaft was loose and the whole thing was wobbling slightly. After retightening the screw and applying locktite, it was fine. I have bought two other Hextronik motors (both larger than this one) and removed the screws and applied locktite to them too.
Efficiency measures in the low 80% range running on 4s LiPoly (Emeter). Pulls 39 amps spinning a 13x6.5 APC E prop.
Plenty of power for .40 sized glow conversions of around 4 to 5 pounds.

This engine gives me full satisfaction, i have to place it in a "Mentor" of "Multiplex" with this battery: ZIPPY 4400mAh 4S1P 15C.
It s a good choice for this trainer plane, power in sufficiency, and appreciable flight time (from 20 to 30 min)
with a propeller APC 13x8 the current is approximately 30 A. At this rate, the engine practically does not heat.
Until now i am delighted by this choice.

This motor is a very good investment, It can run on trainer (Magister), sport plane (Lancair and sailplane (Cularis). Here is my database with 3 and 4S lipo (timing medium).

Quickly settling down to:
52 amps
960 watts
10200 rpm
Very Powerful Motor!!!!

Very nice motor with a lot of pull. I am running it in a 64" wingspan TDM PT-20. The plane weighs approx. 6,6 pounds with a 4S2P 4400mAh battery.
Together with an APC 14" x 7" E and a Hextronix 60A ESC the system draws 38A initial going back to ~34A after awhile.
Pulls the plane around with authority, wide loops from level flight are no problem. 70% throttle gives scale flight.
Motor and ESC stay cool even while fully enclosed in the cowl and only small airstream for cooling. Will try it with a 12" x 8" APC E and 5S2P 4400mAh soon. Should hold up very well.
Very good motor for the money!

I have this motor and the HXT 60 amp speed control in a 4 star 40.
5S A123 pack and a 12x8 APC prop.
34 amps static 520 watts 8300 rpm
Fies the plane extremely well for 9-10 minutes. Not even warm after a flight.
Great combination for 40 size conversions at about the same initial price as a glow setup.
I plan on getting a couple more of these setups.

I bought this motor for my Fliton Andrew Jesky Extra. The plane came out to about 3 lbs. and this motor pulls over 600 constant watts with an APC 14x7E. With nearly a 2.1 power to weight ratio, you can imagine the amount of vertical achieved here. I’m using an LM Loong MAX 2250 4S and a 60amp Speed control.
I highly recommend this motor. It’s smooth, quiet and barely gets warm after a run.

I'm very happy with this motor. Most people are running it with 5 or 6 cells, but I use 3 cells and a big prop on a 3lb (1.5kg) 3D plane - the 57" BladeXL. This give huge amounts of thrust at fairly low speed.
13x8 - 10.7v, 23.7A (253W)
15x8 - 10.2v, 31.9A (325W)
16x8 - 9.75v, 37.6A (366W)
The diameter of the bolt-on shaft is 8mm - you need to drill out APC props a little for this.

| Nicely crafted motor. Excellent finish and fit. Has a 35x20 stator like the TP3520 and almost the same KV but weighs 42 grams less. I ran it up to 7600 rpm with a 12x6 APCE with four Emoli cells and it drew 27 amps. I will be trying five cells as soon as a bigger ESC is freed up. I think that will be the sweet spot.

I had one with debonded magnets. Cam apart during testing , thought I fixed it with epoxy but they came apart in flight. Landed the plane safely.
ordered two more just in case of problem again, but I don't think so. This is my first problem with TGY Motors. 4s4000 on a 14 x 7 turns 665input watts. Good performance.

| I just experienced a 4250-700 motor failure due to loose magnets. Was running up at full throttle to test amperage draw with a 11-6 Master Airscrew prop. and noted a 30-35 amp reading on my Wattmeter. Normally, it reads about 15-20 amps at full throttle. Motor was hot and after cooling off would not run at all. Disassembly revealed all the magnets were separated from the rotating housing. Tried rebonding them with CYA to no avail. Trashed motor.

| My motor looks different than the one pictured. It looks nice but it is Purple and chrome. The motor does NOT weight 195 grams. It weights 220grams and 260gm with the backing plate and prop nuts. I tryed 13.65E prop using a 4 cell 3650 ma Tanic pack and 60 amp speed control. The motor made 440 watts with only a 33 amp draw. Everything was just slightly warm. Not bad but no were near the 720 watts claimed? I will try a 14x7 or step up to a 5 cell but all of this will add more weight and I have to watch the ground clearence now. This is the 3rd motor I bought from UH. Only 1 has really shined. Cheaper is not always better.

Die Motoren dieser Serie kann ich nur empfehlen. Habe mittlerweile verschiedene Grössen in Betrieb ... sehr präziser Rundlauf ... ordentlich gewickelt .. etc. !!
Nicht nur für den Preis klasse Qualität ... selbst bei doppeltem Preis wäre dieser Motor noch sein Geld Wert !!
... also kaufen !!!

| Wow, thats about all I can say. Wow. Seriously. I set this motor up on my Hyperion Extra 260 40e, with the Turnigy Sent. 60 esc and 12/8 prop, on 4s (polyquest) 3300. AUW 1875g complete with HXT 42g MG servos. I showed the motor and built model off to some freinds and I am sure they are going to buy. The complete setup, ready to fly (not including radio) was just over $250. Unbelivable to get performance like this for that price! wow and woooo hooo!!!

I haven't had a chance to set this up to test amp draw and everything yet, but first impressions from looking the motor over are very good. It appears very nicely made. The windings look pretty well done and the finish is pretty nice.
I did chuck it up in my drill press and measured the kv to be 684, so it's pretty close to the listed value. The weight is higher than listed on the site though. The motor alone weighs 217g, the prop adapter/spinner weighs 24g, and the X mount and screws weighs 13g. So all together that's 254g, quite a bit more than the 195g listed on the website.
