Will thin tyres cos our engine to over heat?? If it does ..... why??? Does our engine need to work very hard when the tyres are getting thinner?? Is this the cos of engine overheating?
Actually your engine will be lighter and feel more powerful when your tyres wear down
Also your car will be slower due to the decrease diameter of the tyre, so you will have to throttle more to make up for this decrease in speed and hence the engine will rev more, over-rev and overheats.
i notice a lots of people tune the high speed needle when the car is on the stand. This is not recommended, as this will over rev the engine and in-accurate. the best way is to tune the engine on the track itself.

Once I get those ball park needle settings, I test it on track and tune the HSN further to see if at the longest straights if the engine can hit the high note easy. Once I get that, I tune the LSN so that I get the hardest launch from standstill. But usually, I don't tune the LSN to a lot leaner as I like it to be a little rich on the low end, just enough so that the engine does not flame out. I let the gearing and clutch setup handle the car's pickup. This is because, on a high speed run when the engine is starved from lubrication at high rpm, you will want the engine to immediately get some lubrication when the throttle closes and when the engine goes back to idling.
Of course, all this must take into account the engine temperature limitations

First, you need to watch the car and more importantly, listen to the engine on the longest straights

Having full tank or near empty can affect the amt of fuel reaching the carb; best to tune for mid-point.

hahahh
Guys, what i meant by gears r actually the stuffs needed to play rc n the market price, say how much is a set of wheels, what kind of tools needed to setup the car etc, how much is a set of batteries, what type of things to look out for.

Also best to have only 1/2 tank of fuel in tank when tuning.

Ummm, never thought of that. But then again, most cars should not have any tank problems be it full or half tank or near empty... except maybe an NTC3

This is a tip a got from some GURUs around JB. I believe can be used on any cars
We should not tighten our fuel tank to the car too tightly. We should secure the tanks just at the right tightness so there is a little free play in our tanks.
What i know is this will prevent the fuel tank from over vibration and cos bubbles forming inside the fuel tank. This in turn will cos insufficient fuel into the carb and in the end ..... engine overheating

True! Adding o-rings to the screws on the fuel tanks can overcome this problems. This o-rings will work by absorbing alot of vibration cos by the car. It is not 100% effective, but at least it is better then nothing

If you do not have o-rings available you can use the fuel tube i.e cut few pieces about 2-3 mm each and install it accordingly
thanks
