HXT900 Replacement Gear Set

 MayhemNKMC 293 points

These are replacment gears for the Hextronic HTX-900, although they may fit the turnigy servo just fine, its not what they are for.

Epic winning!

Because they may not pass the quality laws in Europe

especially as they are now black, why are they selling these when they have cone back to white on the servos themselves after customer pressure, just got a set delivered 23/4/2013 in black.

thanks arjen ! many thanks i already ordered 6 of them

 tractor 127 points

mine are the white ones, I have bought over 20 sets and never had a problem. I will probably buy 10 more this year. I abuse these servos realy realy bad, but change the gears and they are ready to go again. I have been told that the black gears are stronger but I have not had the chance to test them out yet.

 Mar11 2113 points

Can i only buy the upper gear? Not the whole set? :-)

 tractor 127 points

No. They are laid out as they go in the servo except lower left is turned over. When placing an order I scroll down to the freight options and see how much I have left before going up the next price increment then add these (5 grams) and other light items to get the most from my shipping money. I use the ems option because it seems to get here much faster.

 Mar11 2113 points

I did the samething...but now i ordered an extra 6

 tractor 127 points

oops, the lower left gear is not turned over, my bad.

 MayhemNKMC 293 points

They probably will be soon, I imagine they are just selling out their existing stock.

 Waiora_protuner 31 points

Old stock perhaps?

 whiskey29 79 points

Are you sure new ones are carbon? The look like black pastiche instead.

 HellyFlyer 1257 points

Old stock go for these better than the carbon ones

 NewToHobbyKing 7072 points

Guys settle down!!! Look at the price. These are cheap gears, for a cheap fix. You can find Carbon Fiber gears else where. Tare!

 Mar11 2113 points

guys so which are the better the white or the black oneas ?
thanks !

 Napstr 707 points

As the original gears are plastic and seem to be quite hardy so most applications don't need the metal gears I don't see them coming up with a replacement metal gear set anytime soon.

 Kiwi_fulla 275 points

The plastic gears are useless after a crash.... metal is much better and reliable and less susceptible to wear and sloppiness

 David 2 points

They dont sell any metal gears of that type of servo but u can always ask at the support center just maybe there is one set out there that we dont know of

 HellyFlyer 1257 points

nope not for HXT900

 HoverTime 34 points

I would just upgrade to the D05010MG 5.7g / .61kg / .07sec Digital Metal for 6.99 it's a lot better. I also used the HXT900 and the gears are just not hard enough now I ended up ordering the D05010MG and the delivery time drives me nuts. But they are good for spares.

 SammyC 81 points

They are supposed to be identical servos, so yes

 ChrisD1972 7 points

ok, thanks. Will order a few sets when they get stock and give them a try.

 SammyC 81 points

 SammyC 81 points

Already Answered

 HellyFlyer 1257 points

Yes these are great although I have never used them as the orignal never strip LOL

 MetalCowboy 81 points

Was there a question?
I´ve used a couple of these, first one after my son dropped the airplane "ass-down" in the floor stripping the gear.
Took me 5 hours to fix the aircraft and 5 minutes to replace the gears.

Good set but routing change of control linkage is better way how to avoid the gear damage. In many cases the linkage is lead at bottom of wing {especially on airplanes with wings at the bottom of fuselage}. Hard landing can cause the contact of the linkage with earth/concrete/hard grass and breakage teeth of gears. I resolved that by routing linkages on upper side of wing (it concerns mainly ailerons, sometimes flaps). It does not look very originally but you can avoid the servos malfunction.

aconselho a compra para reposição, nunca se sabe a hora certa da troca.

 norbique 459 points

i got some of these, and recently I stripped one set after a blowover on my boat. The replacement gears fit nicely and it's very easy to change. Very good value. Highly recommended.

 Mariusz 12 points

gears very well made, fits perfectly replace

 asanado 17 points

Good and cheap

 munsaf 293 points

yes but this gears is not completely fit in tg9 servo if you fit these gears on tg9 your screws is not complitly tiet if you lose your screw the servo is working well but these gears also completely fit in tg9e servo

 HellyFlyer 1257 points

no these gears will not work well this servo as you can't completely tighten the servo box which is very dangerous for the model

 hobbybest 1 points

this replacement gear set is for HXT900 servos.I think that this gears may not completely fit Turnigy TG9 servo.

 JoeHeli 85 points

Yes they will fit it and the tower pro SG90

 Lanell 193 points

some parts may fit.

 GeniolocoSinCura 89 points

con este conjunto de engranajes se pueden reparar los servos esky digital, pero por el costo, usted podría intentar comprar un juego de esto para tratar de reparar el servo

 HellyFlyer 1257 points

Yes it does.

 PeTroK 12 points

I never tried, but is so cheap that is possible to buy and if it don't fits on the servo, just let and save it for another different servo.

 RAFABIANCHINI 30 points

Yes, are the same.

 tommo85 142 points

From what I have read others say in the forum some time ago, the HXT900 and TG9e, are exactly the same servo. Except the TG9e didn't last as long under stress test. Apart from that, they are physically identical. So yes, this gear set should work in a TG9e servo

 Pedro G. 184 points

yes, its fit perfectly

 Harri_s 29 points

Yes it does. I have used these gears on TG9e. They are exact fit.

 Serzhant 56 points

Yes, are the same

 Tony Kwan 4 points

I think not the same as TG9e .....

 Vasco 12 points

perfect thanks HK

 Shura 122 points

Yes, are the same

 Adri-Gja 11 points

yes, you can use without problems

 David 46 points

Did someone let a talking parrot loose in here?

 Azami 2 points

Which is thru? Can fix at TG9e servo or not? Some say yes, but some says no.

 Harri_s 29 points

Yes you can. I have done it several times on my HK450GT cyclic servos. These gears fit tg9e.

 dju29 28 points

buyed some of this and its very usefull

 Kenneth Ablack 220 points

Excellent price for these gears and even more excellent price for the HXT 900 servos. These gears will ensure that yout HXT 900 servos are around for a very long time.

 Kenneth Ablack 220 points

Excellent replacement gears and excellent price too!!!

 richard 5 points

good buy great for those servos whos been in a heli crash

 David 46 points

"BUYED" ???

 fats flyer 104 points

It's cheaper than buying a new servo.
Also , look on the bright side, you'll gain a bit more experience knowing how to fix the servo.
Also, while you have it open, you can reset the servo gears to how you want them so you can zero the trims on your transmitter

 cdis2 91 points

Still cheap as though, and cheaper than a new servo...

 bthanse 168 points

It is very cheap. Try bying servo gears to Futaba or other known brand.

 Rick_BRZ_RJ_CG 48 points

Tip: I've recovered three HXT900 with one kit because each HXT900 broke a different gear. Good luck! Good flights!

 David 46 points

He's right: 25c maybe!

 Egg Man 27 points

You can also fit Hextronic MG-14 or Turnigy MG-90S) metal gears in the HXT900. You need to also swap the top cap from the "doner" servo to the HXT900 because of the ball bearing on the output shaft.

 stgram12 48 points

What do you mean by saying the whole set?
This is only the 4 pieces for the gear set!

 Rick_BRZ_RJ_CG 48 points

In this set there are only four gears of the HXT900 servo, but, i've recovered three HXT900 with this set because each HXT900 broke a different gear. Good luck! Good flights!

 Magule 15 points

Im needing this anwer too...

 fats flyer 104 points

yes ,same servo,different branding

 Harri_s 29 points

Also fits TG9e.

 munsaf 293 points

yes but this gears is not completely fit in tg9 servo if you fit these gears on tg9 your screws is not complitly tiet if you lose your screw the servo is working well but these gears also completely fit in tg9e servo

 Beaufighter 1808 points

Use a drill press or some other kind of vise (a vise and some small washers usually works). Plastic gears don't take heat very well, so pressing by force is the only way. Do not use servo if you have some binding like you say you have, the servo may be taking more amps than it can handle (and more than your BEC can supply, causing RX to stop working)

 Burnaby 529 points

Put in top gear as far as it'll go, then turn upside down onto flat surface and push straight down till the gear either goes in or breaks. If it breaks likely a mfr defeat in which case better to throw away a 3.50 part then risk a crash.

 Burnaby 529 points

Also make sure the spindle is clean, then add bit of gear grease before inserting, then push real hard.
