Electric aircraft with folding wings

It takes 2 minutes to fold the wings of that small electric aircraft. Aircraft characteristics: The plane as you see it on these photos weighs 97k with 20k of ballast in the front to prevent it from tipping backward when the wings are folded. This ballast will be made with batteries. Some parts are too heavy but others not enough. The aluminum cabin must be reinforced and also the landing gear which is not rigid enough. With 10k more batteries, ie 30k in total, plus controls I hope to be less than 120k, which would make a total weight of around 200 / 210k, ie a wing load of 40k / m2 Characteristics: Length Wing span: chord: Wing area Weight (expected): 120k Wing load: 40k / m2 Engines: Rotex REX 50 25KW, or Geiger HPD 20 25KW with a 130/140cm prop. (135cm on the prototype) The towing tests were only done in a field and at low speed, I don't know what it is like on the road. The landing gear does not seem stiff enough and the wheels are mis
