Just received 4 of these servos yesterday. Only one will work, the other three won't chatter, twist, vibrate or anything. Have cross checked known working servos and eliminated every variable except these three servos. Is it possible I got three bad ones out of four?
I have 51 of these servos in planes now. I like them. I can only remember one which came damaged. The lead wire was damaged where it entered the servo body. a few minutes with the soldering iron fixed that. I have a bag with three of these that I fried due to incorrect installation. It's possible I've been lucky with these, but having used almost 100 of these with only one out of the box failure makes me skeptical of bad reviews.
TG9e , Ive been using these along with the HK15178 in my 450 helicopters , and aside from crash damage have been very good servos , and at $2 a pop are possibly the best bang for buck at Hobby King . If your just starting out and are crashing , then I highly recommend the TG9e for use .
They are good servos and priced just right for replacement , buy 10 at a time , that way you'l have servos at all times in your parts box . I dont think I could have afforded to learn to fly 450's without these $2 servos .
If you can afford $25 a pop servos , well good for you , but Im still using $2 servos cos they do a fine job , maybe one day I will move up to $5 a pop servo's - Maybe !
I bought 5 of hxt900 to fill postage, one was faulty, 20 percent failure rate, HK did replace the faulty one, but I don't think much of them, there noisy, and to me poor quality, I buy the HK digital ones for $2.80 or the turnigy servo's, I think both are better than HXT-900's, I might add I had no failures of any including the hxt's in any of my planes. the hxt-900 just sound cheap and nasty, I know they had a bad bunch and I think I got some of them, but each to there own I suppose the HXT's get's good reviews, but not from me.
I'm holding on to a piece of wood as I'm typing this, I've never stripped a gear in any 9g servo, and I've got a few different ones, tower pro, turnigy, hxt-900, and hxt digital's my favourites (they're quieter and just seem better quality) but I have had a few faulty ones! 1 tower pro didn't work at all, 1 HXT-900 that thought it was a jumping bean, and 1 intermittent no brand in my bixler 1 (went full shift intermittently) taught me how to use a glue gun..LOL..If they work I like em too! I reckon the gears may fit the turnigy I know the servo arms match up I just tried them.
It would be interesting if they fit, I only fly foamies at the moment, when you stripped that servo was it in a foamie or balsa elevator/aileron?? my theory is the foam planes collapse rather than the servo's..LOL
There $2, just put an order in for a few of these and forget about them, so when they DO turn up you'll be happy!...I like these servo's too product ID: hkscm9-6, there digital and I've never had one fail,They cost $2.83
Poder pode. Mas pense comigo, se voce tem dinheiro para pagar por um T-REX (Align), o que nao eh barato, porque vai economizar no servo para este heli? Este servo é* ideal para aeromodelos a isopor ou depron, com no maximo 1 metro de asa, quando voce usa equipamentos baratos.
Wow! I tried a digital metal geared servo from another manufacturer to replace an HXT I had in my wood tricopter. It failed and I crashed. I didn't have the HXT because I used it for another project. So, I tried one of these. I truly can't tell the difference! These are great little servos too! It held up fine while I was doing aerobatics.
Bruno, alguns clevis podem não funcionar neste servo pelo tamanho do furo no servo arm. eu uso esse produto neste servo e cabe direitinho, sem precisar aumentar o tamanho do furo no servo arm: www.link
Il faut se connecter, ajouter des objets au panier et c'est affiche. Le port est proportionnel au poids (il y a le poids en gramme a cote de chacun des objets), par ex pour 1,5kg c'est 23$ en port lent (de mé*moire) registered air mail. Ca mets entre 7 jours et 20 jours, et des fois ya de la douane à* payer (pour les colis > 30$ port non inclus). ET pour les gros objets des fois il y a un grand carton, qui pese bien evidemment...
Kevin, it is analog and I used this on my new micro soap box tricopter to see if it would work OK or not. It did a splendid job too accepting the signal from my i86 control board which I believe puts out 50hz for servos.
O TG9 e nã*o tem a mesma forç*a e longevidade como o HXT900.
Certifique-se de suas superfí*cies de controle sã*o livre e sempre verificar servos depois de um pouso forç*ado ou falha! pois pode ser importante para nã*o danificar os modelos... ter atencao a isso. MUITO IMPORTANTE!!!! BEST ANSWER
Certamente aguenta, já* fiz aviõ*es deste porte com este servo, mas fique atento depois de algum tempo de uso. Se vc escutar estalinhos no servo ao dar comando (principalmente no aileron que é* mais pesado), troque o servo, pois a engrenagem está* pulando dentes. Se acontecer isso em vô*o, te derruba com certeza. No aileron, fica mais leve e seguro colocar um servo por aileron e ligar os dois com cabo y. Se minha resposta atendeu sua expectativa, conceda o cré*dito de "best answer".
Oi Bruno, existe uma infinidade de produtos similares. Veja as baterias nanotech, pois com elas vc pode conseguir maior capacidade em menor volume. Entre os ESCs, as vezes até* encontra de capacidade maior (fica com folga e esquenta menos) por preç*o similar. EU procuraria similares! Lembre-se de selecionar minha resposta como a melhor, caso tenha atendido sua expectativa. Boa sorte
Aliá*s, se vc comprar baterias 3s com maior capacidade "c", tudo funciona normal, mas se precisar, a bateria tem maior capacidade de descarga. Em alguns casos, o motor parece até* ficar mais forte. Experimente comprar baterias de 45c. Acho que vai gostar...
Sim, Bruno. Os servos Vê*m com o conector pró*prio para ligar no receptor de rá*dio. Você* só* precisará* de cabos adicionais se sua asa tiver dois servos (um para cada aileron), neste caso você* precisará* um cabo "Y", que liga os dois servos saindo um só* conector para ligar no rá*dio. Lembre-se de selecionar minha resposta como a melhor, caso tenha atendido sua expectativa. Boa sorte
It's similar but not the exact same as the HXT900, however I think the gears should be interchangable. I checked the current draws on 5v: idle, about 10ma, freely moving full swing or with a little resistance, about 100-200ma, and stalled, 600ma. Also, dunno why they call it a 9g servo- it's right around 12 grams, but that's no problem, should be listed as that. Fairly precise, nothing special. However, if you need a cheap servo, this is the one.

It looks like the HXT900, has the same size but is a clone of the HXT900. The precision is a little bit lower than the HXT900, but still good enough. I like the longer wires. It seems that this servo is a bargain buy, but we still do not know what they'll do after hundrets of flights. I'll give 5 stars for now.

This servoe is exactly same as Tower Pro SG90. The plastic case is exactly same, if remove the stickers, you may not be able to point any different. I opened them the electronic circuit board is exactly same as well with same motor same cable with same length. I have replaced the gears and no problem. Even the QC and test stickers inside and out side are same and in the same area. The Tower Pro SG90 is very strong and long life servo.

Installed in cub, beside the TG9, and this one noticably faster... had to replace the TG9 with another 9e. Not sure if I would put this in a high torque demanding application, but for most planes this is perfect, cheap and fast!
I have used this on a home built rafale eurofighter profile plane made from depron foam. I just noticed comparing it to the HXT900 9g (which I also have), its a tad slower. The specs on this turnigy TG9e does say 0.10 sec while the HXT is .12sec. I bought only 2 of these since this is the cheapest servo I could find at the time of my purchase. I suppose this servo can be an indispensible on or a disposable one depending on how you would use it. For me, it served the purpose as tailerons. Quality wise, it does not look any different with the HXT 900 9g. A millimeter difference based on the tech. specs. and it pulls 1.5kg instead of 1.6kg for the HXT900. If you are looking for a cheap servo, this is it. LHS will offer this at a ridiculous 3 times price. I would like to support my LHS but at the price hobbyking is offering these, makes me think twice. I can order spare parts and even with the shipping costs, it will still be cheaper with hobbyking. They just slam the competition if not all, most of the spare parts/planes/heli on LHS.
