Algodoo

at first i thought "meh"

but i played the whole thing and it is actually really impressive, if not a bit slow! 4/5

Impressive, that is really good but you could attach it to better-looking body

I gonna fix the problems on verson 2

I dont make it faster beckause it can be to fast for the track,bad englis

I've seen this design many times before, but this one is pretty good. If you want it to go faster without any problems on the obstacles, add a second set of motor hinges that go faster and have different controls. It lets you go fast on the flat parts and still be able to go slow for the steep parts.

Frank I dont understand how you mean draw a piktchure so i can see

very impessive 4/5

easy to make
