I purchased a Nitrotek car from my son for christmas and it failed straight out the box. The servo or reciever caught fire, it went back to them not once but 3 times for repair. Nitrotek promised to replace it with a new unit but instead they sent the same piece of crap right back to my door again without touching it. It cost me nearly 30 quid in curior fees and 3 months later it still dident run properly. Is it just me or has others had problems with these Nitrotek models? I actualy purchased a reasonably good one from them with lots alluminium parts. In my book Nitrotek = disapointment.
