I am a dealer for RS ULTRA, a great Canadian company that makes awesome flying gear, but they do not make the two stroke motors that are supplied with the paramotors.
It is either RS ULTRA or the dealer that will import the two stroke motor and mount it into RS ULTRA paramotor frame.
I import and support Vittorazi two stroke motors and I also support the Miniplane two stroke motor TOP 80 bacause these are motors I sell.
So if you own some other two stroke motor – I can’t help you with parts. You have to go directly to your motor manufacturer.
