I think the motors are fine by the fact i can occasionally get the front motor to go right and stay right until i switch it off.
I'm sure the motors are fine; like I said - you can keep the chassis, and maybe in the future use it for something else (with separate h-bridges - like a motor shield or two).

I have learnt a lot, i have certainly made some mistakes I won't do again. Like when i cut the wires i left way too much exposed at the bottom when welding.
Yeah - you only want to expose the wire needed and no more; the insulation should be right next to the solder point when you are done (also note: welding is a different process from soldering, and forms of welding - most spot welding - are used in the electronics industry; mainly for making battery packs).

I think the truck was emetec. I will probably try to get the same one although it was on sale in the new year. I think im not ready to buy the $400 one yet, so i might buy another el cheapo one in case i destroy it again.
You've never said where you are located at (country) - but if you live in the States, or have a good selection of thrift stores nearby - check there first. Nearly every weekend I go to Goodwill stores and scrounge for junk; I almost always walk away with 2 or 3 "junk" R/C cars (I think I even have a few emetec's - but mostly New Bright) that have no transmitter; I only pay a max of $5.00 USD for most of them (some of the larger ones I might pay $10.00 for - I did once find an MGA Tarantula (look it up) for $25.00 - that was more than worth it).
Why do I buy them? Well - I have a plan that I am veeeery slooowly executing...

That said it has been a lot of fun, and for the short period i was controlling it from my ipad was very exciting. For now I am going to work on getting the sensors to show up on my ipad and go buy another one tomorrow.
Well, you learned a lot and had some fun! Good for you! Making mistakes is how we learn; sometimes those mistakes can be very expensive (sometimes, they can be fatal - but I doubt this will be the case with a small robot). In this instance though, you lost a minor bit of kit (and I still urge you to check over the Arduino - just to be sure; hook up an LED with a resistor, and check the digital I/O pins for operation - particularly the ones you used for the experiment; the main reason to test this is because if there is damage, you want to fix that too - because otherwise, you'll be trying to build something with a bad system, and you won't know whether the bug is the Arduino, the wiring, or the program - you need "known goods").
Good luck with your next attempt!
