Will the use of the 18T pulley correct the Over drive condition by increasing the rear drive ?

RCPNAMA
First of all: When using the 18t front pulley you need to use the 21t on the front shaft and the 22t on the 2speed shaft. Putting 2 22t pulleys on will probablt not fit!

Using more rear drive will make the car looser out of the corners. Increased rear overdrive will make the rear tires want to constantly overtake the front.

So if your only problem is oversteer out of the corner you could try running more front overdrive. That way the front tires will pull more and stabilise the car.

Usually though it is best to have close to 1:1 drive. That will be best for tire wear and make on and off throttle handling more equal.

Consider this: using more front drive to cure on throttle oversteer will very likely creat off throttle oversteer, because when you lift off the front tires will want to slow more than the rear making the car dive more and thus oversteer into the corner. (this can be cured when using the middle one way option).

Using the 18t is beneficial to equalise tire wear, and will make the car more predictable. Use the side pulleys as mentioned above with a 3mm split.

Hope this clarifies your questions

Hi guys,
I want to measure the temperature of my engine. To get the accurate temperature reading I need to know the emission rate of the cooling head. I got Mega ZX12 DSII engine. What is the emission rate of the cooling head.
Thanks,
oze

Dreddlox, I would not go that heavy on the front diff for tracks around here. 10000 and lower will do. Most tracks in the tri state area have very sharp and quick turns. You want to make that front diff to slow and give you turning.

Hi,

can anyone please tell me the size of the screws that come with the optional 803175 bracket radio plate support? Is there a part number for them?
I ruined two of them and I can't find the replacement in any hardware store.

Thanks

I do not know the answer on your question because I do not have this part. Blackarrow still has got two screws. Why do not you measure the size of those screws and let rccobra know. I am sure these are pretty common metric screws, probably M4 x 10, or so.

It looks to me like 3.5x8mm flat head. Serpent #1277. I hope that works.
