You can pick it up at a local hobby shop. It is spring wire. Good luck with your build!

Hey Big J and Big J. Love your channel and wit! Started your twin rotor autogyro today. Never played with foam board. Been a balsa guy all my young life. But i tell you what. I love this foam!

Balsa is still cool, looks nicer in the end :)

I'm more of a balsa guy myself, even if I've only built two desk top models.

Nice challenge. I notice wing struts on the red one. Did I miss that in the video?

Josh Bixler on June 20, 2012
The red twirl had struts installed due to its heavier weght. We simply ran fiberglass rod from the vertical pylon to the fuselage. The plans also show a strut detail that can be used.

Thanks and Happy building

what kind of receiver do you use on the red twirl?

That was a really good tip about using a drill and sandpaper to create a round hub. To slightly improve on it I'd suggest bringing the sanding block to the rotating hub very slowly to allow the sandpaper to remove only the high-points first without hitting the lower spots. If you quickly apply harder pressure on it the sanding block will go after the high points as well as lower points.

Hey guys. This is going to be my first scratch build!!!! I am very excited. I was wondering if i could use a park 480 motor that I have laying around for the red version. If not do you guys have an alternative motor that I could use for the red that is available in the US warehouse? As I said before this is my first scratch build so when I go onto the hobby king website and see all the different motors I really have no idea where to even start. Thanks in advance!

The origonal plans do not include any doublers. I would like to build the twin twirl as per the plans Josh is using, after surching for them, was unable to find and download any. Is there a seperate set of plans that were made for Josh's plans?

What receiver do you need to fly this plane

Are there plans available that include the "doublers" (those extra parts used to add 2 extra layers to the frame to reinforce it)?

Thanks a lot for the guide!!
