Hi there, June 2022.. time flies!

In September 2021 we demonstrated that R2HOME was possible, with a commercial RC paraglider wing, a P only controller quickly tuned, a wobbly drogchute, cheap servos and a not very reliable software.   

It took about 1 year to transform this prototype into the real system, with a faster wing designed specially for R2HOME, a clean and reliable software. Precision servos and a nicely tuned PID controller. We're also on the third iteration of the onboard computer. 

The result of this work is this video: 

The next step (and I know I've been saying this multiples times already) is obviously higher altitude flights. But this time we're really ready. Like really. 

I've also been working with Lucie Herter, a design student at ECAL in Switzerland on a super nice foam shell designed exactly for higher altitude flights where we have to fight low temperatures. Here is a sneak peek of one of the early test we did with it :)

I'll keep you updated as soon as I have more to share!
