Nano Talon wing mounting parts - no dihedral, flat wing

thingiverse

Want to buy an updated Nano Talon with the wings already flat? Check this out - http://bit.ly/2HU6FbP. These parts are for the Nano Talon FPV plane and replace the stock plastic parts for mounting the wing, removing dihedral from the setup and mounting the wing halves so they're flat. It's intended for use with a flight controller and should eliminate self-righting characteristics or inherent stability on the roll axis. This is desirable with a flight controller, as it doesn't need to fight against self-righting in the stock design. The parts included are two plastic pieces 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. A replacement control horn for the stock aileron linkage is also included, as I broke one while working on these parts. You'll need four wedges, two 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 and 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 easily so the wings are removable. You may need to tweak the square holes depending on 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 early on and ended up removing more than I needed. My wings still fit fine, but it would have been cleaner had I removed less foam there. The wings clip into the side pieces rather firmly and may be a little tough to remove at first. I ended up shaving a little plastic off the point inside the hole that the catches hook onto so they were easier to remove. I considered adjusting the model but decided to leave it as is, as 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'll 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 these parts and do a flat wing conversion, please post your results - I'd love to hear about it! I've had quite a few requests from people without access to a printer for these parts, so I've added them to Shapeways as an option. The side plates and middle joiner piece are there, but 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. The wedges should be super easy to make from just about any scrap material you have around. You can find these parts on my shop at https://www.shapeways.com/shops/bonafidepirate. Update: I've added two more files for the side wing mounts that go into the fuselage, which 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. Make sure to get them aligned properly in the fuse and consider using the slots that remain in the foam if it's not damaged too bad. Update: I changed up the center joiner piece a bit to add some cups on the end that will fit over the side plates, keeping the joiner piece lined up with the side plates and 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 choose 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...
