First to say is this is made up of various sets of parts, body, tail, wing etc. I have put links to the other parts on here at the bottom of this writeup. Use part, all (or none) as you see fit.
This paragraph is on all sets of parts to explain what they are part of.
This is all part of an idea I had to make a modular plane based on being able to assemble different wings / tails based on a 25mm round or 22mm square tube 'stick' body. Ideal for anyone wanting to play with different configurations. Based on the idea of a 'stick' plane being an actual stick. I used 25mm plastic conduit but CF tubes would be lighter.
Each one has a PDF file with photos to help visualise things plus more info and instructions. I used 3mm and 4mm threaded bar a lot, you could glue CF rods but I liked the idea of just unbolting to replace any damage. Adds weight but not a massive amount. Some of the photos may be slightly different to the STLs as they evolved a bit.
This makes the plane in the photos, Wingspan 110cm, Length 90cm, Front of wing to Prop centre 20cm, Wing trailing edge to front of tail 32cm. All sizes are not fixed, just recommended averages. CG is about 1/3 from leading edge of the wing but make it closer just in case, again play around, this is meant to be a chassis for whatever you want to do. Weights are Wing 365g and rest of the plane with motor, servos, nose weight and undercarriage (basically as in photos) 650g. Battery is extra, weight is with PVC conduit 'stick' CF would be a bit lighter.
If I make any changes / updates in future I will add them here. If you modify or upgrade any parts (feel free) just link them back to here.
Updates – None.
So, this is the - Motor.
This has various options to attach a motor to a Stick.
These are a means of attaching a motor with a lightweight holder, this has 3mm threaded bar through the holes and allows small adjustments to motor angle using the nuts, see photos as to what this looks like. Other holder has the 3mm bar glued into it, in case anyone prefers this look. Drill them to bolt through the Stick, I used 3mm threaded bar for this.
The threaded bar attaching the motor allows the thrust angle to be played with. For demo purposes you could set it in the wrong direction and see what happens. Then move to the correct angle. Should be good for teaching, hands on, what happens if it is wrong.
A vernier gauge will give the correct angle (triangle calculator). For example right thrust will be the two threads on the right slightly less than the left. Should give very fine adjustment.
There is also an experimental EDF holder, not even printed it yet, that would attach to the Body Lid or anything else. The base can be fitted and the two parts glued together. Just an idea but worth putting here. Again saw a Flite test plane with something like this on top so thought this would be a neat idea, and no prop to break.
