ady Posted February 29, 2012 Author Share Posted February 29, 2012 my very latest project , a gentle spool up to make sure nought hit , its two rex 600 bolted together , i have tried to hover this but didn`t have correct yaw , the electronics are being sorted , more soon , ady Quote Link to comment Share on other sites More sharing options...
Highlander Posted February 29, 2012 Share Posted February 29, 2012 A very good go at a difficult subject, though too wide too work in a scale fuselage. For yaw control you will need to set a 720 ( or similar) to work the cyclic channels of both heads an exact amount . Best of luck, Cheers, James Edited By Highlander on 29/02/2012 22:50:58 Quote Link to comment Share on other sites More sharing options...
ady Posted March 1, 2012 Author Share Posted March 1, 2012 hello , thanks chap , am awaiting three csm cyclocks to help me on my way Quote Link to comment Share on other sites More sharing options...
Highlander Posted March 1, 2012 Share Posted March 1, 2012 I tried to programme the parameters just for fun this morning but they defeated me. The full size uses differential collective and cyclic together for yaw control with collective reversed below 10% pitch and a curious dead band between 15% and 25% percent while the mechanical mixer changes direction. As your rotors are further apart than scale you may get away with just differential cyclic which would make it a bit easier and you would not have the roll coupling that comes with the differential collective. The design is very stable in the hover but has a tendency to try and pitch down during transition if one is a bit gash on the controls. Watching with interest, Cheers, James Quote Link to comment Share on other sites More sharing options...

ady Posted March 1, 2012 Author Share Posted March 1, 2012 hi james , i build these projects not as scale , but just to try n get to fly , and most of all , enjoy . as with my first tandems , they have a tendancy to pitch down at the back when coming out of a quick circuit , and as no doubt i`ll find some different flying habits of this one too , which is what i like to do , i also try not to cut any parts up as i may go on to try something else later on . thanks for trying different parameters today , once my cyclocs arrive , i`ll get fiddling and post my findings . i`m looking forward just to hovering this one , as to me its different , thanks ady Quote Link to comment Share on other sites More sharing options...
Anthony Billings Posted June 29, 2012 Share Posted June 29, 2012 Reminds me of the Russian (I believe) heli used for carrying logs away, the heli is supposed to be very stable. Quote Link to comment Share on other sites More sharing options...
