Jeroen Ottens Posted August 4, 2012 Posted August 4, 2012 Hi, Half a year ago I designed a counter rotating rotor mechanism for a helicopter. Having solved that puzzle I lacked the ambition to really turn it into a working helicopter. But with the 9396 on the market now there might be others interested so I thought I'd make some pictures of the mechanism and post it here. More detailed photos can be found on my flickr page. If there are any questions or requests for more detailed pictures I'm happy to help out. Leg godt, Jeroen Ottens Quote
Kisvakond Posted August 4, 2012 Posted August 4, 2012 (edited) OMG!!! I wanted it soo badly for ages in a smaller "volume" like this! NICE slim! You know: as you managed to built a smaller coaxial rotor >> you are able build things like the Ka-52 now: I really like this amination: ..and Jernej's great helicopter from 2010 too: Edited August 4, 2012 by Kisvakond Quote
Zerobricks Posted August 4, 2012 Posted August 4, 2012 Good work with using the all bricks and all. Now you just need a model to install it in! Quote
DLuders Posted August 4, 2012 Posted August 4, 2012 Interesting! Have you tried attaching a motor to it? Quote
Jeroen Ottens Posted August 4, 2012 Author Posted August 4, 2012 (edited) DLuders: Interesting! Have you tried attaching a motor to it? Yes I did. I used a PF XL motor and drove it with a train controller to increase the speed slowly to a reasonably high speed. It is quite a sight, it still amazes me to see the rotors rotate against each other :) Jeroen OMG!!! I wanted it soo badly for ages in a smaller "volume" like this! NICE slim! Thanks, it turned out rather compact indeed :) Edited August 4, 2012 by Jeroen Ottens Quote
KEvron Posted August 4, 2012 Posted August 4, 2012 (edited) sleek, economical and efficient design. that's some tasty engineering. KEvron Edited August 4, 2012 by KEvron Quote
Tamas Juhasz Posted August 4, 2012 Posted August 4, 2012 Very clever design, nice work. I hope we will see it in a helicopter. Quote
Thirdwigg Posted August 8, 2012 Posted August 8, 2012 This is a great design. One day when I have some ambition, I will need to build a helicopter for this rotor setup. Very well done. Right now my ambitions are a little overwhelmed. Quote
Lighti Posted September 18, 2015 Posted September 18, 2015 sorry for digging out this old thread @ Jeroen Ottens: what functions provides your design? Having seen the design of Sheepo for his kamov I would like to compare these 2 Quote
Jeroen Ottens Posted September 19, 2015 Author Posted September 19, 2015 This version had only the cyclic control. But the version below also has collective control: Quote
