Thanks for the confirmation. I guess you could turn in and thread the plastic ball joints deeper when you use a longer turnbuckle.

Yes. Side belt dictates the car's rolling friction. Set it as loose as you possibly can.

just curious about my side belt slacking so easily. It's still new...i mean after 10 tanks only...it already showing slack is it normal? im using Max.thanks.
The belt slaking is normal. I believe when I installed it first, I had to use the furtherst setting as it was already tight. The looser the side belt, the better rolling friction the car gets.

Default max engine

Hey D what glow plug are you using in your mova max? I am using a nova rossi C5TF the weather is warm to cool and we use 16% nitro, it is just that i have tried the clutch mod and the settings and my car is still very slow on accelration, iam now worried that i have damaged the engine and which was caused by using wrong glow plug or running it too lean

Well, I'm back in Germany and will have to look through all these postings now, to see what is worth adding to the FAQ
Found a nice 2106 Engine waiting for my 710 from the nice guys from www.the-border.com Just need two servos now and I'll be up-and-running

Ummm, on mine, I found that there is no problem. It fits fine. I thought they were the same measurements as the original...

Open up the engine and check the top of the piston or the button head to see that it's surface is not sandblasted.

You could also look at the condition of the plug. Look at the plug coil to see if the coil is distorted. If it is and you're blowing plugs every now and then, it could be that your engine has too much compression. Look in depth engine tuning tips, look no further than Dennis Richey's site.

Proceed to tune your engine from rich to lean.

Try to pinch the fuel line going into the carb as close as possible. Your engine should not die immediately. If it does, then too lean. If it takes a long time to die, then you're too rich.

When the engine is cold, can you turn the flywheel easily or do you still feel the resistance?

I'll cut and paste a posting I did on the NovaMax engine thread;

If I need to tune the engine to race, what I do is best to set the LSN to 4 turns out and HSN to 6 turns out. I do this on most engines. Idle screw is set such that the slide carb is having about 1 mm hole opening when closed. You need to keep throttling to keep the engine running. Set the LSN to lean it till the engine idle RPM goes up a little and then back out a little till the idle remains constant. That should be the ball park LSN setting. Now tune the HSN till you get the engine revving to the highest RPM very easily. Then back out / richen the HSN a little. Test it on track to fine tune.

If the idle is dropping, lean the LSN a little bit more. Hope that helps.

Well that was those nice guys at pro8 who were able to supply me the Hudy tyre truer at such a good price
I'm pretty interested to see how well this engine runs
May be difficult to run this week - rain forcast the whole week but, as I say the 710 still needs its servos, so it'd be the 705 I'd be testing this week - this time with four wheel driver

Hey thanks for the info D but i think i have my worst fears confirmed after removing the head the top of the piston is very black and rough the bottom of the glow plug the filament seems to have melted to the bottom of the plug! is this a dead engine?

Does not sound good. You can clean the TOP of the piston ONLY with a very mild metal polish. Replace the plug. Check the compression with the method I told you about last time. Then repost back here.

Remember last time when I told you that it should never be slow on acceleration? Well it should not be. Pull into the pits and richen the motor or you WILL kill the motor.
