The rascal is cheaper as well But i think i would still have to go for the NT18T. The rascal is too big Shame it doesnt come with a started box. £74 is awy too much.

o rite. How do you know if you need one?

Hi, Ive just seen the Xray NT18, they look good fun. What are small cars like to drive/tune? Also can you still get small nitro cars these days and how much would they be? Thanks

I think im missing that then How do you tell if you need one as the engine runs? Can you buy them?

Hi, Ive just taken the engine head off to give it a clean. Is there suppposed to be a metal/paper or some other ring between the head and the engine on the hyper 7? Thanks

Yeah white springs are good. Another thing i have done which really helped the handling when on tarmac is replaced the shock oil, i could'nt afford the big bore shocks so i just brought some 40W shock oil and replaced the standard stuff and it now handles 100% better. A very cheap upgrade but would definatly recommend.

LOL i didnt know nitrotek was that bad they didnt know what the needles are called. If it bogs down so much when you accelerate from a stand still you cant get it going then yes i would lean the lsn very slightly justt to help. But don tune the lsn first. I had to do this. when the hyper is factory settngs i have to help it start by giving it a push just until the engine can pull the car and then its ok..

Cool, i thought it might be, i might try slightly leaning the lsn and richening the HSN. I may also drill holes in and the stick some fine mesh wire on the insed to stop any big pieces of rubbish getting in. I think the tnk only lasts about 5 mins, will time it next time im out.

Hi, I have finally got the hyper 7 with the .21 egine out today and stayed out until it was properly tuned and im just wondering if i can double check some things now. There is a good trail all the time when the throttle is applied, but the temperature is 120C/248f is this a bit hot? Should i drill a few holes in the front window as without the shell on it runs about 90C but with it on it goes up, would you say it goes up because its running a bit lean or becaue the shell is stopping air getting to the engine to cool it down? Before i left i cleared the engine and held the fuel line between the tank and the car, it then ran for 6 seconds, this shows its a bit rich doesnt it? Last question, how long should a tank of fuel last when racing? Thanks

Thanks mine current one touches the shell but wondered if it would hurt. Whats the difference betwen these three http://modelsport.co.uk/?CallFunction=ShowSpecification&ItemID=25296 http://modelsport.co.uk/?CallFunction=ShowSpecification&ItemID=23017 and http://modelsport.co.uk/?CallFunction=ShowSpecification&ItemID=23017 apart from

I would try replacing the fuel tubes if you always getting air in them, its either them or the fuel tank but its prob the fuel lines. Have you done anything to break the engine in yet? You shouldnt be running at full throttle if you havnt. You prob will break it. Have you reset your failsafe? I think mine is still a bit tight at tdc. What hapens when it cuts out? Does the revs rise or anything? Or does it just bog down with fuel?

May sound a stupid question but you not just giving it full throttle are you? When mines on the factory setting i literatly have to touh the throttle vary gently otherwise it bogs down, most of the times i had to give it a little push. That will be the low speed. And the high speed may be too lean if you have turned it loads and the unburnt fuel is just when your using low speed.

Whats this like http://www.modelsport.co.uk/?CallFunction=ShowSpecification&ItemID=33955 ? How much better/worse is the gv one http://www.modelsport.co.uk/?CallFunction=ShowSpecification&ItemID=33957 Thanks

Yup they are great, theres a vid somewhere of someeone driving one of a massive cliff and it only broke 1 shock or something.

Thanks for the replys. I have looked at this, does it fit under you shell with room between the air filter and the shell itself as i had to buy a replacement air filter foam and that sticks out a little bit and the shell now constantly touches the air filter.
