Eclipson Model C - build log

#1
After flying my Simple Cub for the last month, I wanted something more. As I've been 3D printing a lot lately, I decided to give the Eclipson Model C a go, as it's such a magnificent plane that reminds me of Draco!

First of all: while it prints fantastic, the winding on this ColorFabb LW-PLA is the worst I've ever come across...


First trial:


Working on the fuselage:









Almost everything printed:


Glueing:





First layers of spraypaint. This LW-PLA is an absolute joy to paint. No primer needed, it sticks great, masking tape comes off easily. The only downside is that masking tape doesn't stick as well as I'd like.




This is where we're at currently. She's got a landing gear, servo's are mounted, paint job is complete and she's fully assembled. The only thing that's missing is my motor, prop and the magnets for the wingtips/front hatch.





I must say so far it's been going a LOT better then I expected. Even on my heavily modified Ender 3 (different hotend, direct drive, ...) the GCode files from Eclipson still work great!

I've been able to spot 2 smaller issues so far. The first is that I've apparently glued on the final tail section with a very slight twist, which means my elevators are slightly angled compared to the main wing.
I'm going to see how she flies, because I'm not really looking forward to cutting that entire section off and glueing it on again...

The second is that because I wanted to get printing done I was impatient and removed some of the pieces of the wing off the heated print bed too fast, causing them to warp apparently. So there's a bit of a gap between the center section and the first section the right. I've filled it with CA, so I'm not expecting this to be a problem.

Very nice job! I've thought about 3D printing a plane but it looks like it would take days to print. I have a mostly stock Ender 3.
I'm with you on that filament. Probably the worst I've seen. I can't believe they sold it like that. I finally stumbled onto the best filament I've used yet. Got it from Amazon. Enotepad filament. Wound beautifully and prints even better. After I tried the first roll of red I bought a roll of black and grey. I've got plenty of filament on hand so printing a plane is no problem. It's just the amount of time it might take. Seeing yours makes me want to give it a shot.

Actual printing time for this plane is around 48 hours, but the largest part is under 7H, so you can print this daytime only in less then a week.

This lightweight PLA was poorly wound, but ColorFabb is the only producer as far as I know and it's a fantastic material! You can't compare it with regular PLA, this stuff is more like paper/foam than plastic...

I had built the Model A (free download) with regular PLA but after several good flights it crashed during a hand launch. I was planing to simply build another Model A but this time with the LW-PLA but decided to buy the files and build the Model C. I did noticed that its more difficult to remove the brim on LW-PLA and it leaves a ragged edge so I might try to print with a skirt instead providing of course the part adheres to the bed.

I use the standard gcodes provided by Eclipson for this one on my heavily modded (direct drive, other hotend, custom firmware, ...) Ender 3. Even though I have quite a bit of 3D printing experience as a hobbyist, I found it hard to beat their provided gcodes.

I've meanwhile printed the entire plane, crashed it into a signpost, cut out a wing section and fuselage section, reprinted those and glued them back in and then had a BEC overheat causing the plane to nosedive into a million pieces. So I've even printed a complete 2nd plane by now, and it's every bit as amazing as the previous one :)

By using painters tape I was able to use a skirt instead of a brim. I also changed the initial layer height from 0.2 to 0.3 to compensate. On another note I am having problems finding the small magnets as Banggood does not ship this item to the US and Amazon no longer have them in stock.

Well, if you can handle 8 weeks for shipping: https://www.amazon.com/dp/B07KP2XLYY/?tag=lstir-20

I bought my magnets on aliexpress, took months to arrive. Meanwhile I had bought another set on amazon (Germany). They're supposed to be the same size, but those I bought on amazon are roughly 1mm wider and 1mm thicker and have a LOT more holding power, a bit too much really.

But hey, at least I now have 30+ spares :)
