The X6 65% Rule, remember that?

[Danosborne6661]

I've owned the Cougar since it's release, I run it indoors on a mix surface track of Carpet and polished floor. The cougar always works pretty well on a high-bite track but I've found as soon as you hit a slippy area it no way near works as well as my X6/B4 have.

When you look at the cougar it does have an awful amount of weight up front. With the servo being mounted really far forward and people running a stick pack battery. For this reason I converted my car to run saddle packs which is the opposite to what most Cougar drivers use, now from when I ran the X6 I learnt the weight you place through-out a 2WD car is crucial so I thought I would work out what the ratios were.



With my newly saddle pack converted car and added weight (Not all the weight as pictured above) to the rear it was still only hitting 59% of the weight at the rear, I was amazed by this as I am running a lot more weight to the rear then a lot of you guys are so I dread to think what sort of weight ratios you lot are running!

Anyways I've added even MORE weight on and around my saddle pack to recreate the 64/65% rear weight ratio which is so perfect on the X6, here is what I am now running

Front - 602g
Rear - 1055g
Total - 1657g

64% Rear ratio, 36% Front

So I chucked the car on the track and instantly it is MILES better, even on shot tyres the car is much more balanced and chuck-able. Generally, what I am trying to say is the 65% X6 rule still applies for the Cougar and my question really is how the F&%$ are you lot running with so much weight up front?!

Here's a pic so you can really see how much weight I am running around my 4400mah Vampire pack to achieve the desired X6 weight of 64% on the rear which makes it feel like the car it should be

Glad you found a way to get the car to handle how you like it.

How did you work out the weight distribution percentages? Would like to do that on my xxx

Cheers

Weight you add around the lipo will also add a portion of it to the front %. try to add weight under the motor area, around the gearbox, etc... But try to keep it as central as possible (for example the weight to the sides of your lipo's is not the best option)

Adding weight further back, for example 20gr, will maybe be like adding 60gr under your lipo (regarding weight % on the rear wheels). I'm just guessing numbers but you get the point. Ideally the weight should not go further than the line of your driveshafts.

Also try a smaller spur so your motor will shift back, this has an even bigger effect than shifting with static weights. (motor shift of 2mm has massive effect on handling).

Way too much time on your hands!

I could of told you a few ways to get more rear end without going for the fat boy saddle conversion!!!

The 65% rule will only work on the X6 when the cells lay across the chassi in stick formation. Now alot of people have gone saddle formation in there X6 (as I have)and like you have with the cougar, the car works better with no weight under the batteries. I have weight in the front bulkhead and under the speedo and thats it maybe the math has changed.

Trishbits rear weight for in front of motor
Trishbits 4degree rear brass block
2.0 rear springs (you could always use the 1.6 if you want to be silly)
Bigger rear wing
Ghea 6 hole rear pistons
27.5 losi oil (I use this indoors currently and upto 35.0w on higher grip)
Alloy gearbox housings
Few 5-10gram weights on back of gearbox housing
Inner on rear mount
Test different anti squat settings
Alloy rear spring cups

If you have too much steering loose some from the front end by adjusting it accordingly to calm the rear end down

Depends if your looking for more side bite on power or off?

Adjust speedo to lowest punch setting
Reduce the steering curve on your tranny
Reduce the throttle curve on the tranny

Too tired now to think of more but there is a few more than likely ive forgot
