Richard Harris Posted December 5, 2021 Author Share Posted December 5, 2021 A single driven blade is more efficient, at the moment the only efficient thing I'm achieving is breaking props! Not wanting to give up easily though Quote Link to comment Share on other sites More sharing options...
Paul De Tourtoulon Posted December 5, 2021 Share Posted December 5, 2021 Breaking props, are you getting it into the air ?, My average was to brake one blade every three flights, so I just made my own,,, Quote Link to comment Share on other sites More sharing options...

I couldnt get it to spin fast enough to start with adding more negative incidence with each attempt. Once it did spin up it was getting into autorotation and a hand launch saw a fast descent. The blade used was a weighted Panther type so it may be a case of lengthening the span to give the extra lift needed. Quote Link to comment Share on other sites More sharing options...

Richard Harris Posted February 4, 2022 Author Share Posted February 4, 2022 (edited) As promised a bit of an update, it's looking like the Gyroo could possibly make the May edition, though this would be the earliest. When I get solid confirmation of I can make up a list of materials/ electrics needed if this will help? On a side note there may be a 3D printed version available to compliment it, the prototype is in early development by a fellow Gyronut , early signs indicate that it flies equally as well as its wooden brother. I have a second model on the building board, I am thinking of making a 2 blade conversion. If there is interest in this I can scribble all the info down and make a set of drawings to compliment, just let me know? I think we may be able to upload PDF's to the new forum?

Outrunner Posted February 4, 2022 Share Posted February 4, 2022 Looking forward to seeing this one in print Rich, I need another simple to build gyro to keep learning on. Also interested in the 2 blade conversion as it must be the ideal model to experiment with 2 blades being nice and light and simple. Quote Link to comment Share on other sites More sharing options...

Richard Harris Posted February 11, 2022 Author Share Posted February 11, 2022 I have now submitted the parts drawing to Sarik Hobbies CAD man so hopefully there is a possibility of a part kit to compliment the Gyroo. Have also made a start on the 2 blade conversion, from experiments in the past I have found that a 2 blade set up needs to have a blade length about 20% extra to that of its 3 blade counterpart. For the Gyroo I will start at 600mm long and see how that works out, blanks are glued together and require profiling over the weekend. The anti strike plate goes on the bottom and is made from 2mm aluminium as it is all I had, on top of this is fibre glass plate to which the blades are bolted to. The larger holes in the alloy plate are clearance holes for the blade mount bolts and nuts, this allows the FG plate to flex up. I will get these parts finished before redesigning the back end to give me the extra clearance needed for 2 blades. Rich Quote Link to comment Share on other sites More sharing options...

Matty, 2 blades are more efficient, cheaper and there are less to break! They also sound better Cons are they are trickier to set up than 3 blades being more sensitive if not tackled correctly. Kind of going from a high winged trainer to a low wing aerobat. Quote Link to comment Share on other sites More sharing options...

Stephen Jones Posted April 2, 2022 Share Posted April 2, 2022 Thanks Richard, Been a while since I built this one and have been asked if I could build one for one or two of these for our club mates. ??

MattyB Posted April 4, 2022 Share Posted April 4, 2022 Looking forward to picking up a copy of RCM&E and grabbing the bits from Coolwinds, though in reality this is more likely to be a winter build (other projects are in front of it in the queue).

My understanding is that Barnes & Noble bookstores stock the USA's version of RCM&E (cannot remember its name off the top of my head), easiest thing to do is to drop the magazine an email for the up to date info you require.
