This is my first model that is using EDF or Electric Ducted Fan. I choose the C variant of F-35 aircraft, mainly because it has bigger wing, I wanted to make sure that it will have enough wingloading to fly. In this model I also share with you couple new things beside by using EDF alone. I share how to make a clear canopy and using servo driven retractable landing gear. The landing gear was bought from Banggood for about 10 dollars a long time ago. What I learned by using EDF is, it's pretty expensive if compare with pusher prop and will fly in a shorter time. I only have effectively 2,5 minutes to fly the jet, the rest is prepare for landing. You have to use 4S 2200mah with minimum 60C discharge rate, otherwise you will have a damaged battery after the first flight. Also EDF models need a decent paved and long runway. If you can access one, EDF jet is amazing.
