Thank you sir, the manual had been amended by my US friend, and now on the website, please attent the Fuel-delivery-system is a key for GT9, GT9 is almost a .56 glow engine, the system solved the issue for fuel transition, nitro fuel is always more viscosity than petrol, Walbro can make the gas engine running well but no small size, so now there is no good way to solve this, the NGH fuel-delivery-system solve it. but please learn how to use the System firstly.
it seems expensive for replace glow engine with a smaller gas engine, so I think the dealers want to give a best price now, NGH never sell to everyone who can pay to protect the partnership. I think the partnership is good will be better to all customers. it is most important and never for Quick-Cash.
All questions will be replied in the future, with no worries for using NGH, but pardon me for my poor Chinese-English.

Seems great but I cant see fuel pump for it.NGH met problems without feed pump on such a glow style carb.So I guess Fox owners will also need this pump too.

Why would gas engines absolutely need a pump?

I dont know but I surely know that NGH has met problems without that pump and they have to design such a pump because there is no such small walbro type carb suitable to small engines.

Without the pump, the carb throat has to be much smaller to get enough vacuum to draw fuel. With the pump and the bigger carb throat means more power. I have an old OS 61 pumped and the carb that goes with it is about 1/3 bigger then the stock carb.
PS You can also set the fuel tank much further back as you aren't concerned with poor fuel draw.

Sir, you are right, another reason is the different viscosity with nitro and petrol, in fact, it is so difficult to do with countless fails, it seems the Fuel-delivery-system solved its problem.

I tried to buy a Fox .50. in Oct this year. Their reply was the engine is backordered and may be quite a while before it is in stock. I have not heard anything else even though my reply to them was to ship as soon as available.
The Fox .50 sounds like a ghost engine. Does anybody ACTUALLY have one?

Ngh 9


I bought one from HiModel.

Looks nice. All necessary bits included, even a spiral plastic ignition HT lead protector.

Will post some pics of what you get 'out of the box' in a couple of days.

Will run on week-end, weather permitting.

Instructions omit reference to the Rc Excel ignition unit but I have used sparky's before so it is no big deal. Beginners could be baffled though.
