i already have this engine, all is good, but if the plane in position Nose up or down, engine going off, what can i do? all setting is good, and still off again,, i use prop MA 11X6, thanks
So how many time does a customer go to Live Cs just to be told that they do not handle that. Sure if it is a complaint it need to go to the Zen Desk. If it is about parts then you have a Product Specialist. But what about that stuff were they are just NEW and do not know how to "TURN it ON" or "Plug it In" or "Set it Up". I know myself that I contact Live Cs, and while they are great, I seem as if they have 4 or 5 things going on.
So what I am thinking is a open chat were Members can chat to Member. Like a chat page. Many members hang out her any way. It is so bad when you try to help and get blamed for taking 10 cents. It is so difficult when your a Newbie, now they cannot reply. This way members can deal with a issue in the real time.
So please consider. Yes payment. Members would have to offer the time for free. At the end of a chat a member could vote on best help as he does now or it could run in conjunction with the Q and A you now run with a option to go live on an Issue! [:D]

Still performing OK with the 46 muffler and pressure fitting and NO pump??
Still going well but starting to miss a little at full throttle. Don't know why.
NGH GT9 is not a good engin. The carb will not close all the way.The pump is a joke. I gave the engin to a frind who runs YS. He put a nitro carb on it with a glow plug. I have four other gas engins. Save your money.
Robert this is not the place for this. There is a review section so such comments. This engine is very cheap. So you get what you pay for. If you got a real bad one why not let HobbyKing know through the Zen Desk.
Nao tenho o que reclamar desse motor. Muito bom. Seguindo as instrucoes de montagem, disposicao das pecas e tipo e quantidade de oleo, funciona perfeitamente. Nao fiz adaptacao para pressurizar. Utilizei a bomba dele. Funcionou perfeitamente. Mangueiras no limite. Nao tive trabalho com ele. Muito bacana
Presado Zilton
Voce eh um dos poucos que ELOGIAM esse motor.
A maioria "desce o pau nele".
Serah que voce teve a sorte de pegar um fora de serie"?
Nada pessoal contra voce, pelo contrario parabenizo pessoas como voce que esclarecem para nos brasileiros as duvidas sobre esses produtos CHINESES. Um abraç*o.
Alberizio, vejo muita gente "descendo o pau nele" e vejo que muitos inventam coisas na montagem! Como mudar o escapamento p um de motor glow, furar o motor p colocar niple p pressurizar e nao usar a bomba pq supostamente essa nao presta, etc... Seguinte: eu segui a montagem como dizia o manual. Inclusive a altura e distancia da bomba do carburador, mangueiras sem muitas voltas, apenas o necessario. Quantidade de oleo e o tipo de oleo. Mandei email p o fabricante e o mesmo confirmou (50 ml de oleo p 1 litro de gas e oleo sintetico). Teve gente que veio me dizer, PRA QUE TANTO OLEO???? TEM QUE AMACIAR COM MINERAL!! Entao meu caro as vezes inventamos dmais e esqcemos que se tem um manual nao custa segui-lo. Esses foruns sao muito bons p trocar experiencias. Caso queira contato ziltonk hotmai. Abraco
Zilton, parabens pela resposta. Infelizmente nesse hobby (principalmente os brazucas) tem muito palpiteiro.... gente que se diz mais entendido do que o proprio fabricante. Ja vi cada coisa..... Sao poucos os que leem, estudam e procuram se modernizar. Os "pilotos" simplesmente sabem. kkkkkk
É* por ai Novato. Tambem ja vi muita coisa q...KKKKKK! Tenho amigo q comprou mudou umas coisas como falei e ta reclamando do motor ate hoje. Fica dizendo q o meu foi o unico q viu prestar! Rsrsr. Pq sera? Abraco
Nao tenho o que reclamar desse motor. Muito bom. Seguindo as instrucoes de montagem, disposicao das pecas e tipo e quantidade de oleo, funciona perfeitamente. Nao tive trabalho com ele.
Ok!
Obrigado pela resposta.
Quando testar o motor, farei questã*o de postar minhas impressõ*es sobre o seu funcionamento, eis que quem compra é* sabedor dos comentá*rios a respeito do mesmo, conforme postei no meu primeiro comentá*rio.
De ante mã*o, digo que nã*o estou arrependido de ter comprado, eis que ainda nã*o tive dissabores com ele.
Na verdade, estou precisando de um motor 15cc ou 20cc para meu novo projeto.
Uma abraç*o Eder e obrigado a todos que sadiamente participaram do meu post.
Bom dia e bons voos!
Eder,
Obrigado pela proposta indecorosa, mais nã*o tenho a mí*nima necessidade de vendê*-lo por preç*o de banana. Melhor deixá*-lo na caixa, pois quem sabe um dia faç*o algumas experiê*ncias com ele.
Tenta a sorte, compre um e veja quanto irá* pagar de imposto, verá* se valeu a pena desvalorizar minha peç*a que te ofereci por 450,00 com o frete por minha conta.
Um abraç*o e nã*o iremos fazer negó*cio.
Olá* Pessoal
A maioria desce o pau nesse motor mas na hora de revender...
Vá* entender.
Se realmente nã*o presta, tambem nã*o vale nada.
Most buyers criticize this engine until they try to resel it by a high price.
If it is not good it is worth nothing.
Eu nã*o estou aqui para "tentar a sorte". Estamos falando de negó*cios e oportunidades. Se nã*o for bom para ambas as partes, nã*o vou me estressar por isso.
These are good little engines but have the pump that really isn't reliable. The fix is simple. 1. Disconnect the pump completely. 2. take the fuel directly to the carby from you tank. 3.Throw away the muffler. 4. attach a Thunder Tiger 46 muffler (it fits perfectly). 5. Attach the breather tube to the new muffler for back pressure into the fuel tank. 6. Set the high end about one turn from zero. 7 set the throttle only a little above idle and it should fire. (NOTE PETROL ENGINES SHOULD BE STARTED JUST ABOVE IDLE ONLY) If not increase the high ONE CLICK AT A TIME. To get perfect performance you may have to lean off the low end A LITTLE.
Worked for me......GOOD LUCK
Starting to miss a little at full throttle. A friend of mine has had no success with this solution. Don't know why, but will let you know when we work it out.
Depois de ouvir tanta gente falar mal, comprei e fiz funcionar muito bem. Um excelente motor. O segredo esta em deixar tudo nivelado e diminuir o má*ximo de mangueira. Depois é* preciso amaciar o motor com 1/4 de ó*leo 2t, com gasolina de aviã*o ou podium. Amaciei usando dois litros de combustí*vel com a agulha bem aberta. Sinceramente o motor é* muito bom. Felicidades
Nã*o foi preciso. Basta reduzir ao má*ximo as mangueiras, e amaciar em bancada. Muito bom o motor até* o momento. Assim quero conseguir mais resultados irei postar.
abraç*o
I have 2 of tham and they are not worth the money. They are not working properly.One was ok but when I have tried to increase rpm he just stop,and it's very hard to start them.
motor muito bom, porem seus componentes* carburador e bomba nã*om funciona direito é* preciso fazer alguns acertos, caso contrario nã*o é* possivel utilizar o motor!!! o fabricante terá* que rever molhorias nas peç*as que acompanham este motor, ou perderã*o muitas vendas!!!
Yes ,sure need a few things to do:No need to use that little pump they provide.Make the engine's connection like the glow as you know from the past.Do not use the exhaust they provide,use a glow engine's size 46 but remember to take out the inside diafram.Don't play very much with the low rpm setting screw.Remember that the hi rpm needle adjustment must be less than a full turn,gasoline runs differently than glow fuel.And finally let free in the air the engine pressure tubing....Good luck.
This petrol engine is not working properly stop idling. Full throttle operation seems normal ls / hs set up as the instructions set screws. However, the throttle stop is low. Can you help me

I have this engine installed on the Hobbyking 0.46 Decathlon it fits right in into any plane that needs a 0.46 or 0.50 plane. It can turn a 11x6 prop at 11,000 RPM. The good thing is that a a OS 46 exhaust will fit perfectly on the exhaust of this engine. the only challanges with this engine is getting it tuned. since there are a few issues with the carb and pump system. you can view my maiden vid on youtube. search "Hobbyking Decathlon with NGH 9cc maiden "

Nao ouvi falar bem deste motor mais comprei para fazer um teste em um Reactor que esta com um motor ASP61. A minha intencao é ter só um tipo de combustivel. Hoje eu tenho aeromodelo com motor 2t, 4t e gas, entao quero ir para a pista com um combustivel só. Depois eu posto dados sobre o motor e mais informaçoes.
Not heard much more bought this engine to test this in a Reactor with a motor ASP61. My intention is to have only one type of fuel. Today I have with model airplane engine 2t, 4t and gas, so I go to the track with a fuel only. After I post data on the engine and further information.
le dimenzioni sono quelle di classe 40 cosi come la potenza, bisogna considerare però un discreto aumento di peso e soprattutto alla necessita dello spazio per la bobina. In compenso la benzina verde (ancora per poco) costa meno del metanolo.
