C-130 build from Cargotrans kit / GWS reincarnation

Lookin' good, can't wait to see it in the air.

And glued with some wheels, noticed the stickers for the front windows were reversed so now it looks better. Next steps motors and hooking up servos when they come.

That looks fantastic! Great work. That was the original plan for mine before I copped out and sprayed it gray...

Good intuition on the servos, I agree the 9g's are over-specc'd for the wings, I downsized mine too.

one last thing I did I forgot to mention, I added some carbon fiber strip glued in edge-wise almost all the way to the wing tips, the amount of unsupported foam worried me, especially in a slightly heavier build like this.

You can see I did 2 but that's because the first was a .5x3mm strip that didn't add enough stiffness, the second was a .6x5mm strip that did the trick.

You may be fine without it, I just wanted to be extra sure.

Again, very impressive, much more detailed than my monotone paint job. I'm curious in particular how you did the front red section, that red band is a complicated shape to "unwrap" and cut for. It looks like you did a better job with the detail decals too, I tried to go off pics online but it wound up a bit wonky.

Here's the rest of the 3D bits I made up for mine, you may be interested in the ESC mount: https://www.thingiverse.com/thing:7202238

I also made a NACA-style duct to cool the ESC since there's no airflow path otherwise. I'm not *too* worried, but it's basically inside an insulated styrofoam cooler so some airflow won't hurt.

Barely sticks out from the fuselage.

Ducts look good, will add them. Thanks for sharing them parts - I'm still impressed by your modelling of the nacelles, above my skill level! and the motors fit perfectly. Was just going to send it and hope (also with the flappy wings) but will find some carbon for them haha

For the Nose covering I made it a bit thinner than scale and wrapped it in the position it fit best - was just a rectangle. I usually low temp iron vinyl on at 175F/50C afterwards to remove wrinkles as it shrinks slighly - this also sticks it to EPO foam well. I was surprised how well it worked, just vinyl I had lying around.

Thanks, those nacelles are the most complicated shape I've attempted yet - I did them in Google SketchUp and my process is messy, but it's a good program for this kind of thing because you can dial in shapes by arbitrarily selecting and moving clusters of points as necessary, which is harder to do in more formal CAD programs.

I rely a lot on mashing 2 simpler shapes together and deleting the excess faces to accomplish Boolean shaping operations. It's interesting to "see" how the world is shaped by CAD operations now, you can start to boil everything down into a handful of blocks and cylinders combined with a few warp and bend operations.

The vinyl looks great, I was considering red monokote because I've previously succeeded in ironing that onto foam at low temp but it seemed risky over such a large area.

I've made waterslide decals with my home printer and some specialty paper before, I bet you could whip up a coast guard decal pretty easily.

So, she's flown. Better than expected and huge power on the 3s. If it was a 3d model it would be hovering on 3/4 throttle, but it cruises around nicely at about 35-40%. Onto the next build. Thanks for those files (and research) Tudordewolf, all worked as it should have.

Nice job! Its a monster!!!

Glad to hear she flew well.

Excellent work!

I just finished patching mine up and it's ready for its 3S maiden.

I'm very pleased to hear the whole power system works together so well, I spent a long time plugging different motor / prop / battery combinations into the calculators to find something light, efficient, and powerful, that wouldn't blow up its motors. Those 4 blade props look fantastic & scale-accurate.

I'm also touched to see my nacelles on another plane, I feel like that doubles the value of the time I put in designing them, that they wound up in 2 builds so far instead of just one.

Here is it flying in wind on 3s - mostly under 1/2 throttle. Really impressed by it.
