I'm curious now. Do you make any of the money back on it? I remember going to little R/C races down at the local Hobby Stop when I was 10 or so and I think they competed for prizes.
Found a rc nitro truck wasnt even 1:5 scale on ebay selling for close to $3000. If i were to pay that much for a RC car it better be big enough for me to ride on to drive to work
