Grasshopper MK3

Auto Credit Based on WinsWings's Pusher Aircraft Challenge [CLOSED]

So a month ago, while bored at school, I decided to make a new plane from scratch. I decided that it was to be as light as possible, with excellent visibility and a very low stall speed. Just for fun, I decided that it would also be a pusher-prop design. So I built it - the Grasshoper MK1. After sitting dormant for a couple of weeks, I saw WinsWings' competition. As I hadn't shared my design yet, I thought it would be cool to enter into the competition. So I updated the design a little - I added a far more ergonomic cockpit, increased the cockpit visibility, changed the gear to a tricycle layout and made the gear semi-retractible. The resulting aircraft, the Mark 3 (we don't talk about the Mark 2) is pretty much exactly as my original design wanted. It flies very well, is controllable at all speeds and very nice to fly, although the roll rate is subpar. I particularly like how the gear partially retracts to make the aircraft more aerodynamic. Anyway, that's all. This isn't a very serious entry into the competition, I just thought it would be nice to have a reason to share a cool plane I've been working on. Have fun!
