1/4 Spit InstGot it fitted in a /4 scale Spit. Weight @ 15kilos. Using a Jeti Spin 200. Has double power connections, so easy to connect 12S 2PTested on a 24 X 12 prop,gives over 6000rpm on the ground. This is as powerful as an 80cc 3W inline twin petrol. Current is about 125A max

Finally got mine delivered... YIKES! Is this thing huge! It also came with a unique prop adapter not shown in pic... (different than that shown in pic). This will go in my Patty Wagstaff 1/4 scale... should fly it like a rocket! :)

This is a powerful motor for the price, but there are some things you should know. The bearings say China right on them, not Japan. The shaft will try to pull out when you tighten your prop. This puts massive load on the rear bearing and it will fail (explode). I thought I had mine running without binding and it still blew up the rear bearing. That bearing is a size I couldn't find for less than $50, so I will make it fit a larger one.

If anyone has an idea how to get the stator off the bearing tube, I'd love to know it! I want to rewind it, but haven't been able to get it apart so far.

Forgot to mention I ran 14s with Jeti spin200 controller. It was really nice before the bearing problem. Super smooth and easily flew a 42% Nemesis pylon racer.

If you have access to a lathe, you can make a spacer to slip over the shaft between the front and rear bearings, this will tke the axial load off the bearings and solve the bearing problem. I measured my motor and I needed to make a spacer that was 57mm long. This is an obvious design flaw that Turnigy should pick up on and correct on future motors to prevent premature bearing failures.

Has anyone had issues with the 12MM prop nutt? Mine appears to be the wrong threat pitch and i cannot seem to find a replacement at the HW store. M12 with a 1.75 pitch does not work... Seems to be a 2.0 pitch but I cannot find a 12M 2.0. Help?

G'day mate, mine is very tight, the only nut that fits is the one that it came with, you'll need a M12 x 1.75 metric die nut to run down the thread.

does anybody know the sizes of the motor length, height?

systemspecialis (67 points) 7/25/2009
Got mine today. I have had some good successes with all sizes of Turnigy Motors (only one duffer).
Compared with the 80-85, this motor is assembled quite differently. The outer casing, as you can see, is secured with a number of countersunk screws around each end. This allows the prop to load against a most massive rear bearing, about 2" in diameter. The 80-85, when the prop is tightened compresses the rotary drum against the front motor bearing, causing it to bind. (in other words, **** design!)
I think that Turnigy have finally realised that some of us put large propellors on their motors, and tighten them up with a spanner!
This one is going into a 1/4scale 35 pound Spitfire, using at least 12S.2P battery pack. I may even go 14S,if the motor will stand it.
I think Jeti Spin 200 is the reliable way to go

Which speed controller do you recommend for these motors?

I have a Jeti Spin 200 for mine. HC, IMHO, don't really have a suitable unit to do justice to this motor. I have only been able to run a quick test of my setup (to go in a 1/4 scale Spitfire)so I cant say anything except it performs as expected. A full test will be made when I get the right prop

Could anyone tell me the dimensions on the HXT80-100-A,,,over all length? The big 7000 watt motor. I am interested in putting it in a PT-19 26 lbs or so

Reply:

somo (2 points);
The body with silver collar (on the threaded end) is 119mm long, the external 12mm threaded shaft is 42mm long, and the plain shaft end is 40mm long (this end on the one I have, has a 5mm thread in this end)... hope this helps

7kW is equivalent to 9.1 HP. That would scoot a bicycle along quite nicely.

Voltage or volt E or V = 48.0 volts (V)
Amperage or current I = 145.8 amperes(A)
Resistivity or resistance R = 0.329 ohms ()
Wattage or power P = 7000 watts (W)
I don't think the resistance of this motor is 17 ohms. At 48v, It takes 145 Amps to push the .329 ohms to 7000 Watts. At 48 Volts with 17 ohms gives you 135.5 Watts and 2.82 amp draw.

HXT 80-100-A 180Kv

Ronny terBeek

WOW !
Gas to electric conversion on a 34% 100cc size Katana.

12S 2P 5000Mah lipo
100A HV turnigy sentilon esc
prop 25" x 10" xoar wood prop (biggest prop I could fit given the ground clearence)
25lbs to 30lbs auw (to be confirmed)

The electric conversion turned out about 1 to 2 lbs lighter than the original petrol (gas) setup when I weighed the components.

Motor simply bolted straight onto existing motor box.
The whole Install took just 30 minutes for motor, esc, batteries.
The original gas setup took me over 20 hours.

Hover at one click over half throttle !

get 2 x 5 minutes mixed flying on one set batteries leaving 32% in the packs.

Flys MUCH better than the original gas setup, and sounds just incredible.
I swear it sounds like a P51 going overhead with supercharger.

Pleased with my first prop selection havn't bothered even trying other props yet because it goes so well.

8 flights last weekend, all very very enjoyable, motor 60 degrees C on the bearing case after a hard fly.

My conclusion from this experiment is that gas to electric conversions get way cheaper and out perform the larger you go.

Brilliant motor.

The only con I can find is to make sure to tighten and maybe locktite motor grub nuts before the prop goes on.
I think I pulled the shaft through a little. I felt the motor tighten up as I tightened the prop nut down.
The shaft is still pulled a little, but it goes so well, I wont bother pulling it apart.

Intended for 85" Yak. Probable AUW 14lbs. Don't need power of previous reviewer so started tests with 20" props. Real figures below that I took standing in a snow storm. That's committment. Enjoy.

First test on 10S and APC 20.5x12 EW prop.

33.99 Volts
61.2 Amps
2135 Watts
5520 Rpm
15lbs 11oz Thrust

Second test on 12S and APC 20.5x12 EW prop.

ATTENTION !!!!!
PLEASE BE AWARE THAT IF YOU DO NOT ATTEMPT TO RUN THIS MOTOR UNLESS YOU INSTALL A SET SCRE IN THE OUTER CASING THAT ATTACHES TO THE MAIN BELL HOUSING. IF YOU DON'T THE OUTER CASING WILL LOOSEN AND CAUSE THE MOTOR TO LOCK AGAINST THE REAR STATIONARY HOUSING. I FOUND THIS OUT THE HARD WAY. AFTER LOCKTIGHTING THE THREADS AND PLACING A SET SCREW IN THE HOUSING IT WILL NOT HAPPEN AGAIN. I NOW HAVE 200 + FLIGHTS ON THE MOTOR.

Problems

Dominic Mitchell

Purchased two of these motors. Good performance for 5-10 short gentle flights (no 3D or aggressive aeros) but then motor seized due to bearing issue. Tried second motor and it got very hot and was tight after cooled down. Similar problems encountered by other users.

This motor is just as big as it is powerful.. It came in earlier today, and went right into my blackjack 55" catamaran... Powered by my PolyQuest 12S1P 5000 mAh 25C, makes a beautiful combo.. This thing is HUGE!!! I will definately purchase more of these for my 1/5th scale land vehicles.. Great Job HobbyCity..!!

Ein unglaublicher Motor, der bei mir zun�chst einen 38ccm TC Zenoah Benzin-Motor ersetzt.
Testeinsatz in meiner 2,1 m Schleppmaschine mit 11 Lipos (Zippy 4500er) und Propeller 20 x 10 und 100A Sentilon Regler(ich taste mich vorsichtig an die Leistungsgrenzen).
Ich werde mit Sicherheit einen zweiten Motor f�r meine 2,8 m Tony Clark Piper kaufen.Bin bisher noch nie von Hobbycity entt�uscht worden!

Deans plugs with a serial y lead will make the esc squeal.

Use 5.5mm + bullit plugs on battery to esc. This also negates the need for a serial y harness.

Super soft start on esc.

Well done HC for a great affordable motor.

Perfect combo on 12s Zippy-R, Sentilon 100A ESC, and 20x12 prop. Why go Hacker or Plettenburg when you can spend a fraction of what they cost. Watch my maiden flight and please leave a comment. http://uk.youtube.com/watch?v=ia20AaEjFg8

I am bench testing before installing into NZ corsair. Check yours screws before using! Outer housing screws were tight but the 2 set scews were not neither were the 4 screws on the back of the motor. Loctite blue and tightened. Running a 24x10 zinger, batt. 2(4500mah life 6s2p) with ESC Turnigy Monster 2000. Wow this motor produces a lot of thrust. Continuing to bench test motor at 1/8, 1/4, 1/2, 3/4, full for 5mins each to see if bearing fails.

The current version of the 80-100 is very different and addresses all the issues I had with the old one. The type with screws around the outer casing is a far superior design:
Rear bearing is very large, almost the full diameter of the can.
No longer uses tiny circlip for retaining the shaft.
Quality and quantity of adhesive retaining the magnets improved.
Four bolt gas style prop adapter, no tightening torque transferred to the bearings.

I will test this motor with Spin-200
in the next week.

Installed this motor in my 30% Yak 54, need 12S lipo as opposed to 10s and 23 x 8 or 24 x 8 prop. Draw is 70amps. Motor is huge and looks well built. Electric is the way....

Joachim Manner

My monster :-)
I will mount it into a 2.4m Yak54 with about 9.5kg of weight.
Powerded by 12s 6000mAh LiPos and a Sentilon 100A. The prop size will be adapted to 90A. First run will be with a 24x8 prop.
I hope this combination will be like the calculated numbers. I want to get out a thrust of approx. 15kg. This should be possible.
As soon as I get more information, I will post it here.
I like hobbycity :-)

This motor is a deal you can not beat. I just flew a 30 lb 42% scale Nemesis F1 racer with it.
Pulled 120 amps on 12s but was flown on 13s 8000mah pack.
Jeti Spin 200 controller which ran it so well that it was cold when I landed.
18 x 18 carbon racing prop.
The motor came back at 160F but I think I can improve that with some cooling ducts. Awesome!

1st flite 24 x 10 prop. Took off 1/2 stik & wow!! More than enough power to hover. I landed to check everything over, motor was hard to turn by hand and seems to have tightened up. May exchange for new unit. Never did go full power yet. Awesome!!!
