Sorry about the link thing…didn’t realize that. people can search the names I posted for the links if they want.
The Kicas kit is for the Vitorazzi Moster 185, which is one of the most common motors (at least in the US). I fly with an EOS 150, which is similar in power, but higher revving. practically ALL these motors use a version of the walbro 37 carb.
Electrical power is a major hurdle. Very few paramotor motors have a generator system built in.The KICAS kit used a 3 phase permanent magnet brushless motor pushed up against the belt drive that goes from the crank to the prop. This has to be sized correctly to not over power the regulator attached to it. There was also a battery in the system, as at idle, the clutch prevents the prop from spinning.
I am planning on experimenting with a wind generator system. Aircraft spruce sells something like it for small airplanes that do not have an electrical system, but it is a little overkill for paramotors. Basically it is a 3 phase permanent magnet motor connected to a regulator with a prop on it and the airspeed spins the motor. This makes it easy to vary the power output as you just adjust the pitch or diameter of the prop… Some wind power regulators will also electrically brake the prop when the battery it is attached to is full, so that helps to not over power it.
