Actually PLA sands very well to a smooth finish, I know, I've done it in this plane.
I have considered using Nylon but it won't work, many parts on the plane need to be glued together (using epoxy) and that would be impossible with Nylon; I don't know about HIPS, does it work with glues? (I suppose it does, being polystyrene)

I just did a quick search on HIPS and the thing that is most interesting to me is that is 20% lighter than PLA, that would be a huge advantage for a plane, in the case of the Nomad it would automatically reduce the weight by 80 grams, from 650 to 570. So I'm going to give it a try to use it in final prints, I still prefer PLA for the development, it prints so easy without a heatbead (no time wasted in cooling down after print) and with no fumes.

Today I did the maiden flight, not too shabby but I need to tweak the controls to make it less responsive to the commands.

I have to compile all the parts and upload them to Thingiverse to replace the ones now there, there have been many design changes. It's a large number of parts, and some are tricky to print so I will also upload the G-Code so anyone can see what were the printing settings for each part.
The landing was not that hard, fast but smooth, nothing was broken; but the second time I over controlled the plane and it crashed on its nose cracking it, so now I'm printing a new one. On the positive side nothing else broke even thoug it was a pretty hard impact, so I'm satisfied with the strenght of the parts.

I just uploaded the STL files to print the plane, plus an OBJ format file with the original meshes so that anyone can play with them.
Nomad UAV Mk.I
I'm going to write a bill of materials tomorrow with all the necessary R/C gear for the plane.

I compiled the list of materials for the plane, I got everything from HobbyKing.com, but the list can be used as a reference to get equivalent parts from other stores:
-Elevon servos: Turnigy TSS-10HM Digital Micro Servo X2
-Flaperon servos: D05010MG 5.7g / .61kg / .07sec Digital Metal Gear Micro Servo X2
-Motor: hexTronik 24gram Brushless Outrunner 1300kv
-ESC: Turnigy AE-25A Brushless ESC
-R/C receiver: OrangeRx Open LRS 433MHz 9Ch Receiver
-Elevon servo pushrod link: Ball and roller link 4.8x2x18mm (10pcs/set) & Threaded Ends M2xL20mm
-Flaperon clevis: Nylon Snap-Click style clevis for 1mm rod
-8x4 propeller (PRODUCT ID: H8011A )
-M3 nylon screws and nuts.
-3mm outer diameter nylon pushrods.
-1mm steel wire for elevon and flaperon linkages.
-8mm and 3mm diamter carbon fiber tube for wing and tail spars, 1,5mm diamter carbon fiber rod for control surface hinges.
-Glass Fiber Cloth 450x1000mm 48g/m2 to reinforce the inside of the fuselage nose section.

No battery? Maybe the parts list is missing the little solar panel that powers everything?
