3D model description
The Angry Hornet
This is another collaborative build between RonStG and myself, taking inspiration from some of the most popular foamie wings on the market we came up with this fully printed design. The Angry Hornet is a 600mm wingspan flying wing with differential thrust and Elevon operation. The majority of the body has been designed for easy assembly without glue, including dove tail slide on wings and connection blocks between the fuse sections that are secured via 2mm screws, this insures that parts are easily replaced if anything gets broken and it's something we really wanted to focus on for "no stress" flying.
The entire body of the plane features a custom made infill structure that is inlaid into the parts using .3mf files. These .3mf files are made specifically for version 4.13 of Cura and are not compatible with 5.xx+ versions of Cura because of the way these versions interpret parts upon loading. These are prepared for you in the release package along with detailed print instructions for each individual piece on the plane, they include setting tweaks and support blockers ect. as well as integrating the custom infill structures properly. It is highly recommended that you use these instead of the included .stl files... Follow the instructions and it will be hard to mess anything up. The wings are designed to take 2 different types of servos, either 9g servos or 2.9 gram linear servos from spectrum.
The 5 main body pieces weigh in around (264 grams of plastic) using polymaker pre-foamed LW-PLA...
I used regular PLA for most of the other small pieces.
Final weight (with all electronics installed) should be between 700gram-800gram
Recommended equipment: motors 1806 2300kv, battery 1500mah3s-2200mah3s, 2x 9g servo or 2x 2.9g spektrum linear servo. 2x 30 amp small drone esc, 1x small 5v bec unit, radio capable of elevon mixing and differential thrust mixing. 2mm screw assortment, 3mm screw assortment (these can be found cheap on amazon), small rubber bands for landing gear shock assembly, 5mmx3mm craft magnets for covers and battery holder, we used the 8 blade 4 inch props from HQProp. they offer way more thrust then we needed, could have probably used a 5inch with lower blade count but these just looked way better. :P
Update 6/24/2023: After a few nose down crashes, we found that the nose tends to break on impact in the receiver compartment area. Easy enough to replace the whole nose via the connection block but it still means you have to print a new nose after a rough crash, we decided to try to prevent this event in the future, I've added our solution into the downloads. Its a 2 piece nose section reinforced with 2 walls in the area of concern with a tip that is designed to shear off on impact using only magnets to attach the tip. the magnets used are the same magnets used for the covers so you should have them available already. This tip can be made from any material such as tpu for extra durability and depending on how much nose weight you need to balance out the craft you can print the tip at different densities to assist in the balance.
Note: In order to print the infill after the walls I have added the infill into the Tip piece via a support blocker, to modify the pattern or density click on the support block and alter these variables from the per part model settings on the left side menu above support blocker option.

Full instructions included with package. This is for use with .4mm nozzles only and requires at least 250mm of diagonal print bed area and Cura version 4.13.
