Scale constant speed variable pitch 4-blade prop for 60size RC airplane

[Rollover0105]

That is amazing! I hope you will market your invention. If you do decide to offer it for sale, please advertise where it could be purchased here. Great job!

Impressive piece of engineering.

To jest temat który bierze mnie przy kolejnych Orlikach które buduję .

Is there an English translation to the forum. I sort of can't read polish :P

[RysiuMal]

@pilotboy84: I'm working on it. In few days I will put all the materials on my website rysium.com. For now you can use google translator from Polish to English.

I cant find this project on the alexrc site. Can you help me?

[RysiuMal]

Youtube does not allow links so i have to describe it: On the forum AlexRc (WIRTUALNY KLUB MODELARZY RC) follow the path: Forum Index -> Rozne -> Projekt smigla o zmiennym skoku - oska z dziura ?

look for threads started by RysiuM.

[cropduster502]

That looks really promissing. Since you have no commercial plans, do you have drawings or detail pictures available?

[RysiuMal]

There is a whole thread on Polish forum AlexRc with detail pictures and even simple plans. However they are no for commercial use.

awesome stuff!

[xKmotx]

OMG! This is completely awesome!! :) You should market this for sale.

I don't mix hobby with business ;-)))

Teraz tylko budować ORLIKA lub TUCANO

Subscribed. I'm curious to see how it will perform on the airplane in flight. Very cool stuff!

[mborja47]

Haha I was just being a smart ass. Still, It's really cool how you machined the hub parts and layed up the blades yourself. Can't wait to see this system on the airplane!

[RysiuMal]

Technically you are right. But in practice it works 90% like constant speed: Throttle controls the power delivered to the prop, and ch-8 know sets the rpm. The pitch is not adjusting itself when prop is unloading in the air, so this part is a miss - however in the real life it will my be no big difference. Replacing TX mixers with on-board power controller will change this setup to true "constant speed". One day maybe ... :-))

[mborja47]

Well technically it's not a "constant speed" propeller. A constant speed prop would be able to self adjust the pitch for altitude and flight attitude within a certain range depending on the position of the prop rpm control. This is more of a "variable pitch" or "adjustable pitch" system. Really cool work though! I was just thinking the other day how someone would do this with an electric RC plane. Great job, man.

Even the sound is REALLY nice!
