DeAgostini's Nitro Racer

***Yes,thats OS No.3,a very popular plug,add this to the above list,sometimes plugs get damaged and the elements squash due to excess fuel in the head,although they still glo they are only working to half capacity,also remember that the life of a glo-plug is between 3-4 hours running time if you are lucky,hot jolts can finish them off in seconds,after this the plugs can break down badly and cause starting problems due to corrosion on the element wire etc,treat them as expensive consumables,some people hang onto glo plugs like a miser ! so just because the plug is new it may still be faulty,always carry a few spares anyway,try another plug.

Also during the run in period,plugs are working extra hard and sometimes blow just like a lightbulb does,ping.

Having said that the manufacturers could easily make a strong sturdy plug that would last for years,but that would be bad for business.

As you can guess my business once revolved around glow engines with the flying school etc and quite often we used to burn a gallon of fuel a day on operations,you get to know the ins and outs pretty quickly when you have a pupil waiting to fly,and the engine will not start ?

the glow plug is brand new which came with the engine.it has "OS A3" written on it

ht eonly times you should remove the plug is if you flood the engine or it dies removing it and putting it back in will give you a crap seal cos when its tighted from new it squishes the washer to make a seal

and heating the block up only losens the piston and liner when they are new beacuse it is still tight

also for the car engines if you can try not to use model technics fuel as its crap

good fuel to go for is tornado but there is a few others like o donnels which is good also

my local model shop actually sell tornado fuel aswell so will purchase some of that instead then..thanks

[Guest]

Keep some spare your localy model shop if there into cars will know the correct one to buy.

[Guest]

for a .12 engine you want to use a medium/hot or a hot plug

ie the a3 or os8

[Guest]

thanks all again for your advice and tips...I upgraded my glow plugs to hot F7,s and my fuel to 16% and the car is running great now...i have been to the school carpark next door and have been coasting it round there,but after a few figure of eights and a bit of four wheel drifting one of the front wheels came away.I have noticed that the drive shaft has come away from the wheel shaft and has caused the screw in the front hub to break through...not happy with that so deagostini will be getting a phone call on monday,and i will see if they will replace those parts.

[Guest]

do you mean the axel has burst through the hub/knuckle ?

get some piccies up of it

[Guest]

will do phoenix,when i get back from work

after 70?

Hi I’m from South Africa and I’m building the Hachette nitro monster truck.

Can any one tell me what issues come after 70 and are it necessary to buy them or can I stop at no 70?

[dynamite25]

You don't need to get the extra issues 71 to 87 to build the truck there just to convert it to the V2 model of the truck so you can stop at issue 70 and build the truck as V1,and with the extra issues you get extra ballraces for front and rear hubs/two speed gearbox/alloy front hubs and blue anodized metal parts to replace the plastic centre braces and some other things.

[Guest]

hmmmmmm two speed gearbox!!! :-) maybe i should....

thanx alot!

I found another problem with my motor. The idling is fine but a soon as it revs up to a 1/4 of its power it cuts out. What can the problem be? I’ve checked the clutch and for any leaks but couldn’t find any thing wrong?

[Guest]

Not knowing this particular engine but looking at this from a general engineering point of view it sounds like fuel starvation. If it works fins at tickover it is obviously getting some fuel through but not enough for higher revs.

Check out fuel filters, kinks in fuel pipes, tank breather, etc...etc...

[Guest]

I am just wondering is it possible to fit a Kyosho GS15R (with touch start adaption) in to the car that came with the Nitro Racer Magazines. As my pull start is slipping when I am pulling it. and I want to replace the engine.

I found this engine on this page

Hi Mole and Welcome to the Forums,

The GS15 should go straight into the Nitro Racer No problem as the crankcase is essentially the same size as the GX12 engines. (I have both engines)

The main concern on the one you are looking at, is to make sure that the exhaust would clear the touch starter...as it has been designed by Kyosho it probably will but I would still check it out. It should fit onto the chassis ok (I have a spare chassis here so I have checked that bit out) If you can find a store near you with one of these engines in why not take your car there and check it out just to make sure.

If it was me I would go for it as I can always do modifications if they were needed.

Pull starts for the GX12 engine are cheap enough to replace new too !!

Regards.......Mark

[Guest]

The engine I was looking at was more than I was willing to spend so. What is involved in fitting a pull start on GX12 engine? And does it have to be a pull start. Can it be roto start or any other kind? I have looked on the internet and can’t find a back plate for the GX12 engine.
