Hey all... Savio here just wanting to share 3 simple mods you can do to your Prime. There are two subtle changes you can do, and another that would require attaining parts for - or making them on your own if you have the means! I did these back in April of 2010... I'll keep this short and sweet with just pics for now. Cut a notch into the shoulder matching the profile of the arm stem for the air filter: See how it fits? And the notch helps to keep the shoulder pad extended out! And to better match the sternum of Prime as seen in the movie, with a cutting wheel, or if you are good with blades anyway... Lastly... the wheel mounts on Prime's hips have been replaced with sliding ones allowing the wheels to slide up where they need to be: Final look: Thanks for checking this out!
