Jon Seals Modded Chassis

[Wacker 2]

Ok, following on from my thread about my Phat Bodies Bodyshell, people have requested that I show details of my modified X6 chassis.

So here goes.

I wanted to run saddle lipos, and not stick lipo from left to right - so I started by dremmelling out some of the interior webbing:



Its actually the webbing that remains that acts as the battery tray and as you can see from the next pic it gave great space for lead plate to be installed as weight - but I could actually put it wherever I wanted, I am still currently playing around with weight distribution at the moment:



I then needed to make a battery strap to hold the new batteries down. I had a sheet of fibreglass so i have used this for now but am in the process of getting a better carbon fibre brace made, which will actually have 4 posts and 4 thumbscrews at each corner of the cells:







However, as you can now see I have very little room for the radio gear (speedo and receiver) so rather than taking out more of the interior webbing, I made a plate to sit just above the webbing and behind the servo. I know this will raise the weight of the electrics up higher, but not a massive problem as they dont weigh very much. Luckily I found some posts (I think from an old 1/12th i used to have) that were the exact height of the webbing, and were threaded at each end. These were screwed into the existing holes in the X6 squared chassis for the back servo mounting:





Bolt the plate on:





... and I now have space for the radio gear. All nice and neat - I know you cant see as the radio gear is not installed (had to take it out to race my 1/12th at the weekend) but the motor wires run along the left hand side of the chassis next to the side of the lipos, meaning I have no wires going over the batteries and getting in the way. I will also be redesigning the radio gear plate in carbon fibre.

What do you think???

Thanks for looking, Jon

you can't polish a terd

you should of bought a master smacker from eric

As much as i realise the modding youve done is excellent job. But wouldnt it be easier to sell your saddles and buy a stick type like i did. You would also be left with a lot more room for radio to sit. Just seems a lot of wasted space down the sides.

I actually managed to fit my saddles in by just cutting the clear shrink off.

I believe the new 09 TP saddles actually fit straight in the X6 and X6^2 chassis end to end

More central weight can only be a good thing, I like this. Try and get some photos of the electronics installed

Master Smacker???

A Master Smacker is the Business!

Eric will be able to sort you out

Sorry, a bit off-topic, but I'm confused by the mention of the following weight transfer theory - "just that they will inherently have less grip due to less weight being moved to the outside wheel."

Unless I've completely forgotton all I ever learned about physics and vehicle dynamincs, the above statement seems a bit backwards to me

We all know that lateral grip increases with more vertical tyre load, but this doesn't occur in a linear fashion, but rather along a non-linear curve.

So, in reality, as body-roll occurs, the rate of increase of vertical load of the outside tyre is less than the rate of decrease of vertical load of the inside tyre, therefore resulting in a net loss of grip.

back to the master smacker subject ive been running one there really balanced. ive been putting extra weight in mine im using an extra 2kg at the front which consists of an old money tin i found full of broken master smacker wishbones and schumacer dogbones . and at the rear ive put in 3kg which consists of an old toaster and kettle .

I'm no motorsport engineer, I am merely passing on my knowledge of what I have tried and tested with my own X-6. If these conclusions do not agree with your text book then personally I'm not all that bothered, I often find that what 'should' work doesn't always, so I prefer to test things out in the real world, it's far more fun that way
