Hello!. I have thousand of vintage hop-ups all new in package. Ebay is to much work to list this amount, So I thought maybe someone here would be interested. I have parts for most every rc from the 80's. Like CRP, MIP, MRP, RCH, Parma, Pro-line, Bo-Link, Trinity, Thorp - Dirtburners, And Many Many More. You can either pick through the list or buy everything for 10k. All parts are listed at
