I've been designing a square tube ultralight and have been having a hard time figuring out how to create a light and cost effective main landing gear.
I've settled on two ways that might work, the first is tubing with a central 'welded mount that the tubing fits in, with a cross wire for bracing (similar to challenger - see purple piece on drawing). The second is flat spring aluminum that bolts into a cross mounted piece of tubing.
Any thoughts on what might work better or is there another method that might work better?
Thanks for any suggestions!
