C172 Mix lever
This page is split into three main sections:
The ultimate printer I can recommend is the Bamboo Labs X1 carbon with AMS if you have deep pockets. ($1200). It's a massive leap forward in 3D printing, with excellent quality and impressive speeds. Its pretty much press print and go as the software and hardware do the calibration before each print. This printer will not manage the larger parts and you are going to need the CREALITY CR10 v3, which is my second choice of printer.
This design was a real challenge from the start. The main aim was to allow for micro-adjustment and rapid lever adjustment. This would allow the unit to operate like a real aircraft. Hidden in the centre section is a screw thread in which a 3mm ball bearing runs. The lever can be operated in course adjustment by pushing the end button. For fine adjustment, the knob is turned clockwise or anticlockwise. This build will require metal rods and tubes, which can not be 3d printed. Check out the parts guide.
