89" SkyWing Laser 260 V2 Assembly Thread

[anaign]

Thanks for the link @anaign - from the looks of it, this product is similar to a product here I'm looking into HTPLA from Proto-Pasta in the USA, it requires annealing to crystallize the plastic to create a more heat resilient product. Anything using a higher temp filament will require substantial upgrades to the printer.

Sorry I haven't posted the baffles yet, kinda resisting posting it for free for everyone. I have yet to receive a "tip" from any upload I've ever created which makes me wonder why I do it other than just being a nice guy.

Hi Nick,
I understand you, sorry I just made a Thingivers account and sent you a PayPal donation for the Air Dams 89 SkyWing Laser Tunnel. Thank you for this fit perfectly, see picture in the attachment.
If you send the "baffles" to me exclusively aigner.a@a1.net I will send another PayPal donation.
regards
Andreas

That is very kind of you Andreas. Pictures alone give me joy!

Another photo dump. Mounted the canister! Woot woot! Not sure why, but my jungle green canister mounts bring me bountiful joy.

Lapped the 2:1 flange mounts lightly, surface prepped with isopropyl, light smear of copper RTV, longer bolts with nordlocks and some more copper RTV on the clean threads as my thread locker.

marked the location of the Teflon coupler to both inputs so I would maintain a gap in between the two for expansion. Heated the Teflon up with a heat gun to help the knurling seal into the Teflon and then put the clamps on.

As for the canister mounts, they were put in place with some clear RTV and clamped down to cure. This way I will be able to remove them if I ever wanted to down the road.

I had a former in the back that was having a bad hair day, so I spruced it up! Literally.... with spruce that was painted and epoxied to it. LOL

Oh I do love some good Progress!!

Beautiful job brother. Looks awesome. And yes, that Jungle Green is a nice color. Especially for a rattle can.

Thanks Mike! Krylon Fusion is good stuff. Super easy to work with.

@anaign I have not forgotten about the baffles. I’ve been busy with other things and just now finished my mesh errors that were driving me nuts. I also added some info to the baffles to signify what they are designed for and by whom (me!).

next I need to reprint and see how it turned out. Hopefully it’s not the last thing you have to do to the plane!

edit: still minor mesh fixes.

Screwed my air dams in place with a bit of clear silicone and clamped them in place. Let it sit overnight and took the clamps off.

One thing that bugged me with my 91ARS is the flex in the fuel tank tray when strapped down. So I put a piece of spruce down underneath to give it a bit of rigidity and epoxied it in place.

Attached my Futaba temp telemetry sensors the the back side of the cylinder wall.

used a piece of silicone fuel tubing to act as a tensioner by pulling it towards the cylinder with some twine thus pushing the sensor against the cylinder. I added some copper RTV to just behind the sensor before pulling it in. Note that I intentionally did not add any to the sensor itself so it doesn’t act like an insulator. Once in place I added a tiny bit more RTV to help secure everything nicely and cleaned it up with Q-Tips.

Skipped over talking about to e throttle servo. I used a ProModeler DS305CLHV for this. I actually had one bad from stock, so that one was sent back. Just so happened to have another one and it’s just fine. Wierd.

I used dubro 2-56 ballinks for 4-40 rods with a Secraft rod. The GP76 throttle arm is for a 2mm so I just oversized it slightly.
Instead of using a mechanical curve, I went with a linear curve. This means the butterfly and the throttle were at the midpoint when setup. At 100% end points the butterfly hits each stop. It takes some tinkering to get it right, but it’s getting the most linear movement from the servo.

Posted my Baffles on Thingiverse! Now anyone who has a printer can download and make my design for themselves! (Here ya go @anaign !)

My only request is that you send/post pics of your printed part to me/here/thingiverse so I can see them in use to bring me some joy. If you are beyond ecstatic that you're not paying someone $40-60 for a set of custom 3DP baffles, feel free to send me a paypal tip for what ever amount you have set in your heart - No demands here. If you'd like a set printed in PLA - I can make that happen for you. If you'd like to make them for someone else, I'd ask you contact me first as the creative copyright claim is non-commercial use.

The updates I've made to the original green baffles that I made include lettering, thinned and cleaned up CAD, small hexagonal tapered and extruded indentations on the inner flange to act like small barbs for the glue. All of this resulted in a faster print time by an overall 30 min. The downside is during that process the walls are not completely even and you'll see some strange indentations. . . it's not your printer... its my doing. The baffles come in at 1.45oz combined.

When you install them, note that the fiberglass cowling when molded creates some irregularities eg: fiber lay up that sticks up higher as well as excess resin. You'll need to trim that stuff down a bit. The other thing to note, is you'll want a bit of clearance from the cylinder fins, as PLA, PTEG, ABS, HTPLA will all warp if heated at some point above 200F - especially considering how thin these are. I'm not sure how much clearance is needed at this time. Print with 100% infill. Green PLA is KCamel, Blue Winter HTPLA is Proto-Pasta.
