The paper airplane is more than a piece of folded paper that glides and turns before hitting the ground--its a classic part of growing up. We all made them, some that worked well and others that tanked immediately after takeoff.
Theyre a low-tech fixture in a high-tech world, so when inventor and pilot Shai Goitein created a module that turns the classic paper airplane into a Bluetooth-enabled smart phone-controlled paper airplane, he risked stomping on nostalgia.
But the PowerUp 3.0 is so simple to understand that instead of messing with a classic theyve brought renewed interest to the paper airplane, and just in time before every kid gives up their notepads for an iPad.

Are you sure they were well-meaning? LOL!
I would suggest that depends on your definition of efficiency.
One definition would be the extent to which a system provides for the wants and needs of those it serves. For that definition the one-lamp approach isn’t efficient at all, as one lamp type simply cannot meet diverse needs.
I don’t have a smart phone. But now I want one.
“I would suggest that depends on your definition of efficiency.”
You are 100% correct, sir. 99% of the world’s arguments could be quickly disposed of if the parties involved would first agree on the definition of the terms they use.
You’re gonna want one, right?
Any one see any logical reason why the electronics would not work this way?
(not the power for the electric motors- the controller circuts)
The controllers would be switching more current for the increased power moters - and are most probably not rated for this. Depending on how the control is done, one might be able to simply add a couple of components in the control output that would switch the increased current.
In addition, the actual control circuitry is designed for the mechanical lags/etc of that small airframe. Make things bigger, and things might not work so well.
The above is vastly simplified, but one never knows. You can always try. Don’t spend too many bucks and stand far back when you fire it up.
Good luck.
my goal is to build one man-sized (capable of lifting at least 300 pounds.
Does anyone know of a good tiny gas or other-fueld engine that would only have to run at constand speed?
I wanted to use one to re-charge the batteries while it was flying
I was thinking the same thing. This has potential well beyond the paper airplane. Need to find the code signals the app sends and design a receiver for a much bigger vehicle.
Too true!
You didn’t build that. Someone else made that happen
Perfect! LOL!
I would think your new electric motors would need to have very low tolerances for voltage regulation. If not you are going to have a hell of a time controlling flight.
