Our High Altitude Balloon (HAB) project aims to return the electronics on board a HAB autonomously. Traditionally, weather and HAB's return electronics safely to the ground via parachute, but this…Continue

Pure glider on ArduPlane?

Started Aug 17 0 Replies

I'm new to Arduplane, but is it possible to have an aircraft be a pure glider (no motor)? How would I set it up to work this way? I'll be sending a high altitude balloon up to film the eclipse this…Continue

Wiring issues?

Started Aug 15 0 Replies

So, my motors do not get any signal at all. They just "beep" to signify no signal being received. If i hook them up to my receiver they can calibrate, work, etc just fine.Currently I have the…Continue

"More or less, Tarik.  Delta wings have the advantage of vortex lift (Google it) so they potentially suffer less from low Re effects which could help expanding their useful AoA envelope, plus they are nice and stiff for a given wing area. In…"

"I was under the impression that roll and pitch would operate like torque. Put the control surfaces further out from the pivot point and you have more authority. Increase the surface area, and you would increase your force or pressure acting at that…"

"You definitely could! The Sr-71's flown pretty high, and a bunch of airplanes have flown above 100,000 feet. Just increase control surface area + airspeed, and at some point you'd definitely be able to control the aircraft.  It isnt…"

"I disagree that you can't fly at 100k feet.  IMO you can if you get your aerodynamics right but the flight envelope shrinks a lot"

"I would've loved this years ago. You guys have a number for the price yet? I'm guessing this is going to be quite pricey though right? FLIR cameras themselves are expensive to begin with. "

Our High Altitude Balloon (HAB) project aims to return the electronics on board a weather balloon autonomously instead of drifting away on a parachute. My Project Log series aims to provide short sweet and to the point updates to said project. Heres the most recent one:

Heres some background:
