v2 Quick Change gearbox with extra spring and motor

just pulled this out of a like new replica.  i shimmed, radiused and greased it then re-assembled.  it runs very smooth now!  there was zero wear on any parts, i looks brand new inside.  it chrono'd at 1.1 joules before cleaning, but in case the fps went up from a slightly better air seal, another spring is included.  it has small tamiya connector, but if you would like a deans i can put one on for free.  this has a quick spring change guide in the rear so changing the spring is extremely easy.  shipping in holland is a flat rate 7.25 paid by the buyer.
