      Here's what I've decided to do: No welding involved. The gear uses 25x25 steel tubes bolted together, with NAPA shock absorber...

      Another quick question: would using a 50mm OD steel tube be stronger/weaker than a 50mm square tube of same wall thickness? A square...

      Thanks for the link, addaon. So, using rubber shock bushings, I can dispense with the bungees. Neat. Also, if I drilled a 5mm hole...

      Question: What stops the HM14 axel from moving laterally? I can't see any retaining mechanism or bracket in the photo. I've gone in...

      Hi guys, I asked for advice and suggestions, because I value input from folks more knowledgeable than I. So thank you for your input...

      Not sure if this comment is helpful, but it might be, so here goes. When I've been working through my design, I've found that it's...

      And why not something in betwin? like the first Fleas, one, (or two) simple axle(s) , 4130 tubes, sandows, and big low pressure...

      ...and it keeps the scaffolding out of the way of the pilot's legs (which are outside the fuselage).

      What about this? 25mm square tubing flush with the sides of the fuselage, obviating the need for cross-braces. The axle is an airfoil...

      Hi. I'm still agonising over the gear. My preference would be for taildragger gear, but one of my local advisors has strongly...

      The wing folding mechanism has also gone through a number of changes, but I think I've nailed it. I'm currently printing the prototypes...
