It's doable. I posted something very similar where a dirt bike can become amphibious or airborne depending on how you reconfigure its parts, but the liability issues of being the company to build the first one are prohibitively harsh, so you'll just have to build one and then play with it while we try to go-fund-me your bail money. |

It could include a ballistic parachute and airbags |
|
| |
Also, even if you can only take off and land from airfields, the fact that you can drive it there and drive it away means you save on the expense of hangar fees. |
|

Another thing - small aircraft often suffer from the problem of low wing-loading, which makes them susceptible to being easily buffeted and even flipped over by small winds / turbulence (Plenty of youtube videos showing this.) The solution is to keep the wing size down in order to increase the wing loading - and that works well for this compact form factor design. |

Do you need a pilots license to ride this dirt bike? |
|
| |
Hey - I just thought of a name! |
|
| |
We'll call it the Flike / Flyke.
(One will be American spelling, the other British.) |
|
| |
@2 fries shy of a happy meal: License? Meh, depends on which country you're in. |
|
| |
3-wheels-and-a-lot-bigger looks more expensive and more drag-prone. Flike 2-wheeler looks to be a more manageable size to keep costs down. |
|
| |
I'm imagining empty unladen weight to be ~450-500 kg approx. |
|
| |
For engine, I was thinking of a wankel rotary, which gives better power-to-weight as well as lesser vibration, compared to reciprocating piston engine. But I'm open to better suggestions. |
|
| |
Well, maybe if a lot of carbon fiber was creatively used, then weight could be brought down to 400kg. A light aircraft engine like Rotax 912 comes to just over 55kg weight. |
|
| |
One issue with engines is that the powerplant needs of a motorcycle / ground vehicle are different from those of an aircraft. An aircraft engine should have a highly optimized and narrow powerband, while a motorcycle engine is going to need a somewhat wider power band. |
|
| |
Sail planes land on one wheel all the time. One or two wheels is what many classical models have always had. |
|
| |
Front wheel of Flike would have to be kept in a straight position during landing/takeoff - but that would also be a requirement for high speed ground driving. |
|
| |
You could link the front wheel to the rudder with a self-stabilising feedback mechanism. |
|
| |
Yeah, I was thinking about the rudder, but forgot. It's hard to imagine where the rudder is supposed to emerge from when converting to aircraft mode. |
|
| |
Another idea I had was to make the Flike into a quad-copter like the JetsonOne. Somehow the rotors would have to swivel out from the vehicle to convert it into aircraft mode. Quad-copter just uses differential thrust for steering. |
