i have spent countless hours browsing the german ttt sites including thorsten's
i had stumbled into bit's and moded them as much as i could. i got into my mini z for a while and forgot about my bit's.

then i got my overland and started talking to my new friend overlander

and remembered thorsten's and other sites for the ttt's. that's how, as overlander said, this thread began.
i got some prices for those who are new to the thead or just curious as to what costs are involved. these are approximates and not exact.
faller car system starter set - $50
roco miinitanks 470 man 4x4 - $8
gwsr-4pt reciever - $22
gws pico servo - $20
batteries - $2-5 each (has anyone priced an assembled 4pack)
gwt-4a transmitter - $30
gws cn12-b2 motor - can't find price. would the motor from the faller car work?
add cost of brass parts - screws, nuts and washers are expensive.
add cost of soldering supplies - rather cheap
add cost of burns, cuts, cursing in frustration, wife complaining your spending to much time on it, you little kids trying to use you as a jungle gym as your trying to assemble a size 80 brass screw-nut and washer and other trials and tribulation.
all you have to do is look at overlander's, killer's and thorsten's work to know it's worth it.
