And did we mention the wings fold up so you can store it in your garage? Want to build your own? [John] still sells the plans. But don’t jump into this without testing the water first — the frame is entirely hand-welded and he estimates it takes between 4,000 and 5,000 hours ...
While it does look like a helicopter mated with an airplane, it’s actually a bit different. The rotor isn’t normally powered at all. However, it does turn in forward flight and generates about half the lift the plane needs. That explains the stubby wings. The topside rotor has small ...
The first thing to learn in float flying is how to taxi. Without a water rudder, it may be difficult to turn a model on the water, especially when the wind is blowing. It always helps to hold the control stick back so that the elevator is fully up. Small blasts of throttle should b...
Professor and department head for the School of Aeronautics and Astronautics at Purdue University Bill Crossley answers questions about airplanes and aerospace engineering from Twitter. How do airplane wings generate the necessary amount of lift to achie
The Lock BottombyFold ‘N Fly– This airplane is fairly easy to make and throws really nicely! You can also get creative with adjusting the wings to change how it flies. #5 Loop De Loop Paper Airplane Loop De Loop Paper AirplanebyJuniors Art and DIY– The harder you throw this one, ...
This shape makes the parachute act like a wing (see How Airplanes Work for a description of wings). Instead of coming straight down like you would with a round parachute, you actually glide in with a ram-air chute. You also have a lot of control with a ram-air chute. You have two ...
Copied the settings (diff all) from inav 7.1.2 and pasted them into inav 8.0 RC3. In navigation modes the plane flies unstably. https://youtu.be/n69w9CDaM8Q (OSD is a little out of sync) There is no SD card on board. Maybe I configured s...
→ The lift produced by a Frisbee as it flies through the air is similar to the lift generated by an airplane’s wings. The perfect throw helps the disc push air downward without generating too much drag. In return, air pushes the Frisbee back up, generating additional lift. In 2005, re...
Wu says he never flies without travel insurance — so that if something happens, and he loses his belongings in an evacuation, he won’t be out of pocket. And both Thomas and Galea stress that choosing your airline wisely is also key. ...
