Retractable propeller - in the nose - designed by Eugenio Pagliano and adapted by Paul Friez on the glider (Swift)

For those that don't know adding weight to a modern fiberglass glider is a preferred flying experience for experience pilots it gives the glider legs and makes it more enjoyable the sink rate is hardly affected with a modern glider

[@JaleelJohanson62]

Nice piece of engineering there!

[@skylarkman2000]

Amazing idea .

[@OnerousEthic]

Sheesh! RC? I want this in real life!

[@ctuna2011]

they already have ones that are conformal once they stop spinning.

[@jean-emmanuelpons5011]

Super Paul!!! Vais essayer ce système sur le cyclique de mon 412!!!

[@lesp315]

This is brilliant! Congratulation!

[@BrianPhillipsRC]

very cool!

[@asterix1936]

...un bellissimo progetto....

[@KennethWhiteakaruckusbringa]

would it be possible to have some sort of clutch system where the propeller drive motor does the extension and retraction fwd then reverse while clutch is disengaged and when its engaged it turns the prop ?

[@TheSoaringChannel]

That's freaking slick lol

[@brucebaxter6923]

Very nice. What’s the max speed the blades still fold at?

[@gregcaspn]

Must of worked on the reaper progecto

[@laurencefavis6839]

what controller are you using for forward and reverse of the lead screw motor? thanks

[@SkylineatME]

it sounds like a "a 10 Thunderbold"

[@RoboTekno]

Are the extra ounces in the prop retract mechanism weight worth the loss in drag or is this purely a cosmetic upgrade? Great work nonetheless.

[@leifvejby8023]

Absolutely worth the extra weight!

[@RoboTekno]

***** So it's mainly meant as a cosmetic upgrade, correct?

[@leifvejby8023]

No, the drag reduction is absolutely worth the extra weight. And most gliders need some weight at the front anyway.

[@RoboTekno]

***** Gotcha

[@JohnSmith-nh9pm]

fucking awsome !!

[@bashougardy]

Bonjour! I have problems with the prop that gets in unbalance when startup. Do you have information of how both props should open at the same time?? thank you for your reply. Seb

[@PaulFriez]

bashougardy The propellers must have the same point of rest. This is to be adjusted on the support of aluminum propeller

[@bashougardy]

Paul F Must it be very loose? My propellors move because of the wind. I must tighten the bolts on alu propholder I guess.. Thank you for your reply!

[@PaulFriez]

bashougardy Bonjour Au repos les hélices doivent avoir exactement le même point de repli. Au besoin mettre du scotch mousse (genre double face épais) . sinon il faut s'inspirer de ça : www.dr-martin-thoma.com/mediapool/140/1409981/data/Propmechanismus.JPG mais je ne l ai pas réalisé . Paul

[@markdam]

Why so noisy?

[@johnnyllooddte3415]

??? if its in the nose its backwards

[@RWHITT]

Clever stuff :-)

[@BabaBaba-cb8jm]

ow very nice

[@fredericborloo1910]

Jaw on floor!

[@jackson1231970]

super !!!

[@sufysprojects2689]

Slightly over-engineered😂😂
