off topic but , i would say avoid the"protaitone" kits found on ebay . yes they are really cheap but ... look into it before you hit buy now as the two i dealt with had a lot of errors , no documentation and a lot of other folks ran into many issues with this companys kits .
yes you can get them to work , but in my case they shipped wrong components , no instructions , some of the parts would not fit , the wiring diagram photo i found on ebay was wrong , so yes they are a great deal , can be made to work but be aware , there is no instructions and there will be errors , wrong stuff , cheap junk etc . although the chassis / paint job was very nice and once i figured it all out , it works well but i wasnt ready for all that and it really irked me how the seller kept stalling and treated me very rudely .
i expected to quickly assemble this when it ended up consuming a lot more frustrating time so the second kit is just sitting there till i can figure out all the errors and pull a proper bomb . number two was shipped with a whole different set of headaches .
