Hello, thanks for this great site. A very useful tool to choose sets and see what others sets we can "almost" build. The evolution with using onlys parts list will be really great too ...

Just like me ... bienvenue à bord ;)

Somebody have already done the swashplate : http://www.eurobricks.com/forum/index.php?showtopic=64073&view=findpost&p=1156736

Hello i think it is a very interesting challenge. I fly RC helicopters and know very well what produces lift. You need to make blades with a particular profile. The real problem is to stay "light" as much as possible and "rigid". I think i will try to make a blade on LDD ... The blade shape of lego technic is quite good but it is not wide enough. The next problem will be the rotor in the boom, it should also generate tranversal lift to stabilize the helicopter. Whitout rear rotor it will twist around the main rotor due to the counter torque generated by the main blades. One solution is to make a "coaxial" helicopter with two rotor "counter" rotating, like those helicopters mini toys. Or with two separated rotors always "counter" rotating like the well known shinook helicopter. The last problem will be to move the helicopter with "cyclic" commands, that would be a really hard work with lego. Yous should make what we call a "swashplate" to command the "pitch" of the blades. But a double counter rotating rotor helicopter should almost "lift off ground" ... i think its possible. With a rotor sized as the 8068 box ( Rescue helicopter ), the main rotor should run at almost 3000 rpm to generate lift, that is really fast for a lego structure ...

Hello my name is Daniel and i played legos when i was 10 in 1985. I didn't have lots of legos, but i enjoyed every little boxes i had. My brothers offered me two boxes of legos this christmas and i restarted playing "again" with legos ... I surfed on the net about legos and i fell here. I discovered LDD, really amazing soft ... I started modeling the 8070 Super Car box. The hot rod version is almost 85% done ... see attached file. Thanks for this great site/forum.
