Posted September 16, 20213 yr Hi all, I'm happy to present my newest MOC, a propeller plane with realistic controls. This is the list of functions: Working rudder Working ailerons Working elevator Openable canopy Freely spinning propeller Steering rear wheel It is a medium sized build at 707 parts. The dimensions are as follows: length: 30 cm / 11" width: 33 cm / 13" height: 10 cm / 4" The working controls are the main part of the plane. This is an overview of the mechanisms:Propeller plane controls by Jerry LEGO Creations, on Flickr The yellow parts control the elevator, the yellow the ailerons and the magenta parts are for the rudder. The way the ailerons and elevator work are not too complex. By moving the yoke forwards and backwards, the rearmost connector also moves. This connector is connected to the elevator. The ailerons are connected to the yoke via a set of gears. The most interesting part of these 2 mechanisms, is the CV joint. This joint allows the axle to move in and out easily, while transferring the rotation to the gears. The way the rudder works is a bit more complex. Here is a render showing the different parts of that mechanism:details pedals by Jerry LEGO Creations, on Flickr The yellow parts are the pedals. When you push a pedal forwards, it also pushes a purple liftarm forwards. To this liftarm a rubber band is attached at the bushes. The rubber band makes the rudder return to centre. The purple liftarm is blocked from moving backwards (towards the seat) by the dark green parts. This is done to make sure that both rubber bands don't cancel each other out. The movement from the pedals is transferred to the light blue liftarms. These are in turn attached to the lime parts. The lime 3L liftarm rotates about the pin in the middle. It is also the link between both pedals. The lime green thin liftarms are connected to an axle which finally rotates the rudder. Renders showing the mechanisms in action can be seen at 1:19 in the video.

September 16, 20213 yr Wow, great functionality and very impressive presentation! Those animations of the render really help to understand how it all works. Great work!
September 16, 20213 yr I'm not a plane person usually, but the amount of work that's gone into those mechanisms is amazing! Great job on 'em.
September 16, 20213 yr Well done, fantastic functionality with only 700 parts, it's on my build list!

I knew it was possible to make make the controls work, but to make them fit in a plane this size was a whole new (but fun) challenge. 16 minutes ago, Pattspatt said: Wow, great functionality and very impressive presentation!

Glad to hear you liked the render, I figured that would be the best way to present them 2 minutes ago, Maaboo35 said: I'm not a plane person usually, but the amount of work that's gone into those mechanisms is amazing!

September 16, 20213 yr Superb job on the mechanisms! I quite like the minimalist canopy, too - the two twisted flex axles manage to evoke the shape nicely.

Hahah thanks, no need to pay for this one though 1 hour ago, PassengerJet said: This is fantastic truly! Like @Maaboo35 said, I'll take is as high praise! 19 minutes ago, Hrafn said: Superb job on the mechanisms!

I'm also quite happy with the canopy, more than this would probably have been too much
