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 - Body.
Made up of the main body, which is a box you put the ‘stick’ through. Space either side for receiver and ESC. One uses 3mm rods glued in holes to support these, the deeper one has a printed base and so a larger space for electronics.
There is a groove at the rear for an aerial from the receiver, if it has two, so they can be at 90 degrees.
The body lid sits on top and you can attach any wing to it, it can be held by threaded bar or elastic bands. There are dihedral blocks to allow wings to be fitted to it.
Basically put the body on the ‘stick’ and attach your wing(s) to the lid(s) and play around as you like. In part inspired by Flite Test sticking a KF airfoil on a plane, made me think of swappable wings and this idea kicked off.
The Body Lid has a servo slot so you can use one servo in the centre to control both ailerons.
The Lid can be attached using the Body Lid Thumbscrew, and cowling, if required. This is just a thumbscrew with a nut glued inside it that takes a 4mm threaded bar.
For the brave the body can be turned ‘upside down' allowing a low wing option. Just means fitting the wings using dihedral blocks but the other way, then maybe foam to cover the centre and land on ?
