    Ideal Weight distribution

    Hi, Let's suppose I know the wing load and total weight of a plane Is there a way to calculate or find out the ideal weights of the individual parts of the plane like fuselage and wing? Or with other words: What is the ideal weight distribution?

    Wing weight

    Hi, I was just wondering whether there are some rules for how heavy an airplane wing must be at least and at most relative to the whole airplane weight in order for it to fly? Thanks in advance

Engine filled with oil (5 quarts) and coolant (6 quarts 50/50 water/glycol). No prop. Gear legs mounted. 370 pounds on digital bathroom scale...

    Wing design for lightest possible wing

I'm thinking that the spars would be according to Jim Marske's designs: composite web or sandwich web, with the caps being made from...

If it is braced, the brace will attach to wing only 3.5 ft from the fuselage leaving a full 9 ft hanging out there. 4.6ft wide. gross weight plane 580lbs. Trying for 6G max load...

    Choosing wood over aluminium worth it?

    I've found wonderful resources on a future project I'd like to start early on, an ultralight glider. As things go, the plans for aircraft of this type are usually aluminium tubing and bolted joints (nothing welded or made of machined metal). Would it first off be possible to replace all...
