Default First test of my prototype

X7, i did the math

I've been working on a new idea, and today i could finally test it on the track.
X6 is a wonderful car, but we can't stop the development, right?

I'm just hating saddle packs, and refuse to use 'em, but wanted to change the layout on the car. I noticed the difference already on the first lap, it jumps much better, and is much quicker around tight turns then the original. My fastest lap with the squared is 28,0, with the X7 i did a 27,64. It's a bit more difficult to drive, the rear is more loose, and demands more of the driver. But with more tests and setups it might be more forgiving.
This is just a quick build prototype to test the idea, and I will make a carbon fibre chassis later.
This is the beast:

that looks alot better than the saddle pack i think your on the money with this i think this is what X factory should bring out and not the saddle pack
good work!!!
try running greens springs on the rear with NO 1 pistons that should help with a more planted rear!!!!!
second hole out from the inside of tower and out side hole on the arm you may find its got to much grip on the rear now and 30w oil allround!!!

I didn't play around with the setup, i used the same as on the X6 to compare.

The idea was just to test this one a few laps, but i think i will run it on the next race

Nice. Just wondering why you've mounted the speed controller and receiver on the same side of the chassis. Is it to counter balance the weight of the motor?

Simple reason, the cable between RX and ESC was to short
But after i mounted it, i saw, just like you, that it compensate the motor weight.

Nice job I think the Team C / Ansmann mid is going to allow the stick battery to go either way but I'd have to have another look to be sure, I was just converting mine when they announced the new chassis so now I'm just waiting for the parts instead (lazy)

Still waiting for parts for the carbon version.

Small progress. I'm still playing around and having fun with my new milling mashine.

If that's Proline Calibers try going out with them turned the other way around, and you'll get a lot more forward bite!

Nice work! Keep in mind though that the Schumacher Cougar SV already takes stickpacks along the centerline of the chassis!

(for those who want a car like that without all the modification work...)

Razer, when are you gonna try it??? Put that vintage XXX-CR on the shelf now and go for it!

No offence, I'm sure your project/mod will be great! Just trying to say it's not really a new idea as there is a mid motor car for sale already with this battery layout

I saw from the Euros that some french guys have also been running a custom made car with mid motor and a stickpack along the center, with great success it seemed.

Does the Cougar SV have the same wheelbase as the X-6, S2 etc? (is it longer?) Looks like your proto is quite a bit longer, how much vs. standard?

Say what you like, but the solution from Schuey as to the steering servo looks smart!

I've never said it was a new idea.

Mine is 9mm longer then standard, and about the same wheelbase as a RB5, the only car i've compared it to. The real version will be shorter.

According to owners the Cougar steering is a pain in the *ss to work with.

I own a cougar sv and the steering is verry easy to work with and i like the fact you dont need to use a silly low profile servo ..

What's wrong with low profile servos? IMHO you'd have to be stupid to still buy regular size servos these days...

Hottuna: Nice job man, I know the guys who race the french car and I had the chance to try it, it's very very good indeed.
