Nano Talon wing mounting parts - no dihedral, flat wing

These are parts for the Nano Talon FPV plane, they replace the 'stock' plastic parts for mounting the wing. This will take out the dihedral from the stock setup and mount the wing halves so the wing is flat. It's intended for using with a flight controller, and should remove any self righting characteristics from the plane, or inherent stability on the roll axis. This is desirable with a flight controller, so it doesn't need to fight (or work against) the self righting in the stock design. At least that's the theory, I have yet to test fly this. Once I do, I'll post a video here with the results.

Included are the two plastic pieces which are glued into the sides of the fuselage, a center joiner for the spars that mounts to the plywood plate in the fuselage, and some wedges for leveling the stock aileron linkage pieces. Also included is a replacement control horn for the stock aileron linkage, I broke one of mine while working on these parts and needed a replacement. You shouldn't need it unless you're as clumsy as I was... lol You'll need four wedges, two fit under each of the aileron linkage parts. It will be obvious once you pull the plastic pieces from the foam fuselage.

I printed all these parts in PETG (black Novamaker) on an Anet A8. I had to carefully adjust the clearance a few times to get the spars to fit snug enough not to move, yet still slide in and out easy enough so the wings are still removable. You may need to tweak the square holes depending how close your printer's calibration is to mine. Mine is decent, but may not be perfect. You'll also need to trim a bit of foam from the bottom of the top hatch which covers these parts, since it's molded to match the stock parts that sit a little lower in the center than this configuration does. I suggest not trimming any foam from the wing roots until everything else is done and finished, then adjust the fit as necessary. I trimmed a bit of foam from mine early on in this 'project' and ended up removing more than I needed. My wings still fit fine, but it would have been a little cleaner had I removed less foam there.

The wings clip into the side pieces rather firmly, and may be a little tough to remove them at first. I ended up shaving a little plastic off the point inside the hole that the catches 'hook' onto so they were a little easier to remove. I considered adjusting the model, but decided to leave it as is. I'd rather have a more positive engagement that you can adjust to your liking, than end up with one that doesn't latch in place securely enough. ;)

I will leave this marked as a work in progress until I've test flown the plane, though all the parts do fit great. If you print the parts and do a flat wing conversion, please post your results, I'd love to hear about it! Enjoy!

I've had quite a few requests from people without access to a printer for these parts. I've added them to Shapeways as an option. The side plates and middle joiner piece are there. The little wedges were priced rather high for what they are, and would need the points cut off for Shapeways to be able to print them, so I left just the main parts. The wedges should be super easy to make from just about any scrap material you have around. ;) https://www.shapeways.com/shops/bonafidepirate

Update 7-13-2018: Test flight done, it works! Here's a video: https://www.youtube.com/watch?v=ld9OA-ziLEU

Update 7-14-2018: Added two more files for the side wing mounts that go into the fuselage, these have an extra wall around the outside to give some area to glue into the fuselage if you've damaged the foam when removing the stock parts. Put the pieces in place on side of the fuselage and trace around the, then cut the foam out to glue these in. Please note that I haven not printed or tested these, I just made them at the request of someone else. I see no reason the won't work, but consider them "experimental" anyway. ;) Make sure to get the aligned properly in the fuse, if possible use the slots that remain in the foam if it's not damaged too bad. It's important to have these positioned in the fuselage properly to keep the wing straight and aligned with the rest of the plane.

Update 7-17-2018: I changed up the center joiner piece a bit to add some "cups" on the end that will fit over the side plates. These serve two purposes. One, they will keep the joiner piece lined up with the side plates, making it easier to insert the wings/spars into the fuselage. They also give you the option of gluing the parts together once everything is in place, for a much more rigid center structure. If you chose to glue it in, make sure the wing fits and everything lines up first, then REMOVE the wings before gluing it with thin CA or similar. You definitely don't want the wing in place until the glue has ample time to cure fully, or you could end up with a permanently mounted wing!

Print Settings

Printer:

Anet A8

Rafts:

No

Supports:

No

Resolution:

0.2

Infill:

50%

Notes:

I sliced all these parts in Simplify3D, and printed them at 0.2mm layer height. I used a 0.4mm nozzle and printed with a 0.4mm line width. I used a relatively high infill (50% rectilinear) for strength in the joiner piece, and also 3 walls, 3 top and bottom layers. The rest of the parts are rather thin and will fill in completely for the most part.

You should not need supports for any of the parts, although the joiner piece will have to bridge over the top of the hole for the spars. I've added an extra 0.1mm clearance to account for some sagging there and it worked great on my printer. If you have issues with that, try printing with support in there, but it may be difficult to push the support out. Your call!
