Does anybody have some info on those Cox production engines available everywhere for around $9.00 each? Are they Nost legal? They’ve got this big ol’ funky vent tube coming up off the backplate. Please, Please, does anyone have some tips on seting up a fuel system for these guys. I would really like to run them with a bit of pressure, but don’t know if this works with a reed valve. Maybe a low pressure balloon set-up?
Any help would be greatly appreciated.
