Leonardo + Quadcopter

thingiverse

This was a project from the NCC Fab Lab class. In this class, we took a group of students and put them through their paces to teach them basic CAD, 3D printing, laser cutting, vinyl plotting, etc. Leonardo is a + style 450 quadcopter that uses a + configuration to make it easier for first-time builders/fliers to visualize the flight system in relation to the airframe. As built, Leonardo has enough power and stability to do a fair amount of lifting. There are many ways this design could be improved, and we encourage everyone to do so on their own. Our course was not about building the best and most awesome quadcopter but rather using various processes to create something. I'm posting the files here for students to access replacement parts and show off their efforts, design changes, successes, and failures. Print Settings Printer Brand: Stratasys Printer: uPrint SE Supports: Yes How I Designed This As time allows, I'll post more information about the process. For now, take a look at the BOM to see all the parts purchased for building quadcopters in class. The airframe is made from Baltic Birch plywood and has been designed as a modular unit where arms can be replaced individually if they become damaged in a crash. However, this design allows the airframe to have a bit of flex. Gluing the arms to the hubs using Titebond III wood glue will make the airframe much more rigid. If you choose to do this, keep in mind that in the event of a crash, the entire airframe may need to be replaced. The landing gear were 3D printed on a U-Print using standard support material and ABS for the model material. You could use PLA without any issue if needed. There are two different files for the landing gear, one is longer than the other. Other than that, there are no real differences. I prefer the longer ones for basic flight as they help keep the props out of taller grass at the flying field. These could be made much longer to facilitate a belly camera or other attachment if needed. The flight control is an Open Pilot CC3D setup using Open Pilot's ground control software.
