Foam F-35 Learns to Hover

With affordable RC {hardware}, tough motors, and high-capacity battery packs, getting one thing to fly hasn’t ever been more straightforward. It additionally is helping that, whether or not you’re into fixed-wing craft or multirotors, there’s quite a lot of knowledge and prior artwork floating round on-line that you’ll be able to use to jumpstart your individual construct. However in terms of homebrew vertical take-off and touchdown (VTOL) planes, issues are slightly trickier.(*15*)

Fortunately for us, (*4*)[Nicholas Rehm] has made all of the plans and data essential to copy his implausible RC F-35 to be had for any person who desires to experiment with those slightly area of interest fliers. Although it was once a normal park flier, the construct can be value a detailed glance due to the vectored thrust motors that give it out of the ordinary maneuverability and a best pace within the neighboorhood of 120 KPH (80 MPH). However with the flick of a transfer, the aircraft transitions right into a tricopter-like flight mode that permits it to land and takeoff vertically.(*15*)

(*3*)(*1*)How does it paintings? The downward going through motor simply at the back of the “cockpit” lifts up the entrance of the froth flier and tilts left and proper to supply yaw keep an eye on, whilst the two motors at the again tilt down to boost up the rear of the airplane. Aviation buffs within the target audience might acknowledge this as being somewhat just about how the real F-35B hovers, despite the fact that on the actual jet fighter, downward thrust underneath the wings is generated by way of redirected turbine exhaust fairly than devoted motors, and yaw keep an eye on is supplied by way of swiveling the engine’s nozzle fairly than the entrance carry fan.(*15*)

Getting the aircraft to takeoff vertically was once one factor, however with the ability to transition from a hover into ahead flight was once slightly any other. To make this aerial transformation imaginable [Nicholas] in reality needed to write his personal flight controller tool, which he calls dRehmFlight. The GPLv3 code runs at the Teensy 4.0 and makes use of the average GY-521 MPU6050 gyroscope/accelerometer, so that you don’t want to get any customized forums spun up simply to offer it a take a look at pressure(*13*) flight. Within the video under he walks thru configuring the tool for VTOL operation by way of defining how each and every keep an eye on floor and motor is to reply to keep an eye on enter given the these days decided on flight mode.(*15*)

It almost certainly gained’t marvel you to listen to that this isn’t the primary time [Nicholas] has experimented with peculiar flying machines. Closing 12 months we coated his RC Starship, which controlled to stay the “abdominal flop” touchdown even ahead of SpaceX controlled to get the actual existence model down in one piece.(*15*)
