you can click on the yellow box w/ FAXON CONVERSIONS in it found on the HOME page here or also TRACK48 SHOP page. I sent you a price list with available kits to your e-mail. Thanks
Quarter-kit.com does a conversion for the Hobby Boss. I did the Faxon M4A2 version and it works just fine - just carefully sand the bottom of the hull at a straight angle.
