Great replica, has been used a handfull of times.  I tuned it up just to fix the weak spots. 
Gears have been shimmed and short stroked.
Simple mosfet added to protect the trigger contacts.
Added a maple leaf macaron yellow to give it some range
 Everything works as it should
I have plenty of replicas so this can go.  I am not looking for a trade, money talks.  Feel free to give a realistic offer.
450 takes it, shipping included (its big and heavy so it wont be cheap)
