Good luck to you fella, better than spending money on video games, drink and smoking.

It makes you very employable, having the skills to do something like this.

yes its alot of money, but what else could give you a bigger smile on your face :)

It nice to have something to do when doing test. All work just gets you stressed a little fun in there relaxes you.

Watching

 

 

What has age got to do with spending a lot of money? At least he's spending it on something he enjoys and will probably learn a lot from building it. AT least he's not spending his money on Booze, fags and drugs like me ( I'm joking ..just booze and fags!)

 

 Gotta be one of the best statements i've read on this forum.

 

 

Good luck buddy!

The torque values seem low, although it makes my head hurt trying to scale them for the car?  I'm guessing due the the final drive ratio.  Is it not better to gear for a more realistic top speed and have the torque to accelerate before you run out of road and to combat air resistance?

just thought i would let you guys now that i might be changing the car to a 2wd design with a solid rear axle as i think i am going to have some problems with running a stretched mi4, this is why designing a car can take so long :lol:  back to sketch up it is

car is almost out of the design phase and should be going into the part making stage at the end of august, a few things have changed on the car like the steering set up and the axle setup but changing these things have saved me a lot of money and time
