your not going to lose money
the price of those crappy radios dont inflate the cost of the rtr that much. they dont cost ofna that much.

i kow you wont get full price for it but if you look at the current auctions on ebay for the "crappy" rtr radio for the mbx pro, the guy is getting almost $70 for that crappy radio and crappy servos.
just minus what you do get for it from the price of the rtr and use that omney towards after market stuff.
you prolly already have a radio so use what you get for the rtr radio and deduct it from the cost of the buggy

dont tell me you cant just ressell the crappt rtr stuff....proof is right there....sure you wont get full retail for it, but they dont add full retail to the price of buggy.

this debate will go on forever. unless they start making kits this is your only option.
