Good monday endless, just reporting from the weekends adventure.
It all started with a calm friday evening and there were a couple of bored engineering students in the student goverend electronics lab.
Three hours and a couple of beers later this magnificent beast was created.

So far i have only used an old 5A 18s turnigy pack, but the final pack is 20s. As far as topspeed goes i have no mesurement of that yet.
The drivetrain sure works fine exept hitting lvc due to the old tiny pack, but i would be very suprised if i manage to bust the controler after last nights...
Tweaked the belt tensioner and now there is no skipping. Sence there are no more skipping it will do burnouts like a charm :lol:
It might not be the fastest but good enough to give people the "grin" (and grown men giggeling like little girls), and confusing limited competent cameramen...
It is alive.
Finished building the new beltensioner yesterday, so i took it on the obligatory testdrive in ducktape-mode. works fine exept that i seem to get it to cog over at full power.
And it does great donuts on gravel. 8)
Pictures comming soon.
burner77 I must say that i love the idea to get in to a market just too compete with a company that have failed to deliver what they promised.

Ps. Same reason for why Lamborghini started...
