Good evening,
I'm designing a small personal ultralight and I'm wondering what size wheels are usually run. What actually interest is what the smallest possible wheels are for a lightweight project like this. I'm designing a retractable wheel setup with very limited space. The aircraft would be launched and recovered strictly from a paved airfield, not a grass runway. I was hoping for something (wheel and tire) smaller than 3" in width and 8" in diameter. Also requires brakes, however small; stall speed should be around 50 knots and a maximum ramp weight of about 850lbs. I figure it shouldn't be too hard to control with a 5000' runway. I've scoured the internet and haven't been able to find anything of the sorts - closest I've found is a 4.10/3.50x5 which has a 10" dimeter??
