We recommend that this is the maximum size/weight combination for the Jetworks parkjets that :-
a) Have space to house it.
b) Have a larger wing area.
Remember – Foam Parkjets are fragile and adding heavy EDF systems can overstress the airframes. They need faster launches and landings.
To give maximum performance whilst keeping weight low George Worley at 4-max (UK) has put together a special EDF / ESC / Battery Combination together to suit this plane.
