I have 3 chassis that have some problems & one boy without a soldering iron (me)

1 27 mhz zipzap chassis (doesn't steer one way)
1 49 mhz chassis (also doesn't steer one way
1 27 mhz chassis (doesn't work, dunno whats wrong)

PLEASE don't post rude remarks like "buy a soldering iron" or "you should learn how to solder" because I have no $$ whatsoever (waiting paitiently & diligentally til I turn 14 when I can apply for a job & by then all the jobs will be filled & I'll have to wait to turn 15 ) I'm interested in a complete 27 mhz zipzap chassis (don't need motor but EVERYTHING else, even body IF you can or a complete 27 mhz MICROSIZER OR BIT-CHAR-G BRAND ONLY!!! chassis. Chassis needs EVERYTHING exept motor & body. Thank you (I will trade more than non-working 1 chassis for a complete WORKING chassis)
