Hi! I'm currently running a Vx.18 in my HSP all alloy (almost) build. I want to get a bit more power/speed, due to the gearbox design I can't simply add a dual clutch/gearing. So I was wondering if I could swap in a .21 or bigger engine without too much issue? Do I need a special mount convertor? And could I use my old engine Carb, which is rotary? I've noticed most blocks of .21 or bigger use the push pull design carbs.
