Hello folks. Thought I’d share this - it’s a simple EDF jet made from 6mm foam (sold for home insulation). As I’m in the UK that’s the best build material I can get hold of currently. Decent foamboard is very hard to find…
The design steals ideas from a few places - notably looking at Ben Harber’s jet designs, and also Jetworks online planes. Those things are beautiful (take a look at the ones ShadeyB has done - he does the build videos on YT and posts on these forums) but take a lot of work to build. I decided to design something similar but much easier to build that I could use to get used to flying these things, then once it’s had one too many crashes graduate to a Jetworks scale beauty!
Design is basically a box with a flat plate wing, and some minimal concessions to aerodynamic reality and a bit of “scale” shape. Currently it’s flying off 3s and it’s easy to handle - and easy to hand launch. Next steps are to add some cheater holes to increase the fan throughput and upgrade to a 4s battery.
Quite pleased with how well it turned out considering how basic it is!
A few build photos below to give you the idea of how it goes together.
Fan is a QX-Motor 64mm with a 3800kv motor. Servos are cheap 9g metal geared. Very cheap 60A ESC and currently 2200 3s battery. Flight times about 3 and a half minutes of not very aggressive flying.
