Engine Cowls done
Oooooo. Nice! Can't wait for this.
How the heck did you print that in 1 hours 18 minutes??
The river and panel detail is great! Congrats!

:) An hour for 1... just put them all on the plate for a pic.

Didn't design it... only printed it. Designed by Troy McMillan.
Full nacelle, made up of the wing attachment section, the motor housing, and the motor cowl.
Looks really nice!
Pratt & Whitney Engines done.
I think I've decided to do a yellow fuselage. It's not scale... but I can't see scale in the air. Yellow I can see.
The second pic shows have the attachment area for the retract and the steering servo recess.
Looks awesome Davey.
Largest part of the wing... probably the longest print time... 11 hours.
Build in support for where the Nacelle and Retract goes. Really excellent design for a tear away section that allows the rest of the wing to print properly.
Fuselage 2 with Fuselage 1 also showing the steering servo and front retract.
Full fuselage done... just taped together to get a sense of the size of this thing. It's big.
Wow!
Looks pretty amazing Dave. I am happy to see we both seem to keep our workspaces with about the same amount of stuff everywhere. Makes me feel more normal.
Windows on
Front Landing Gear installed
Battery Hatch installed
Battery and RX Tray installed
Tail done
Looks amazing!
Dave,
An incredible project. The sound should be awesome.
Any decision on the power.... other than "motors with enough power"? ;)
I will buy a ticket to watch the maiden flight.

Four SunnySky 2212 1400KV motors with a 30A ESC each.
2 x 2200mAh 4S.
3-blade Master Airscrew 8x6 props. CW and CCW.
1 battery will drive the outside motors and the other battery will drive the inside motors.
Bit of a cool pic... inside the fuselage.
This is a rally great build, Dave and an amazing model. Wow!
Wing done. 1.8m. 6ft. Now... for the electronics.
Looking great Dave!
I'm curious, after printing do you epoxy or cover at all?
No epoxy or covering... it usually adds too much weight. You can't do anything that involves heat, either.
I usually print in the colours I want... in the colours I can see while flying. If printed in white or gray, then the control surfaces, wings tips, etc, will be orange or red... something to make it pop in the air.
Others have used epoxy or fiberglass, mainly for strength, but the printed weight is essentially the flying weight, so they end up with a much heavier plane.
Decals and paint are usually applied. I've got a doors and windows decals that's going on.
Motors ready to go in. I'm using SunnySky 2212 1400Kv. I managed to find CW prop adapters so I've got 2 CCW and 2 CW.
The inside of the motor mount is printed to fit 3mm nuts. I hope things will not get too warm, but just in case, the motor mounts are printed with PETG rather than PLA. PETG is a bit more heat resistant than PLA.
You never fail until you stop trying.
Reminds me of:
"It's not how many times you fall, it's how many times you get back up."
Cop: "That's not how roadside sobriety tests work."
Nacelles installed.
ESC wires pulled... whew!
How many times did you cut yourself on the PLA?
Never happened. Stuck my finger on a wire yesterday... but no PLA issues.
Installing the motors.
There is a Motor Mount Tool that gets installed on the motor and motor mount.
CA is applied onto the motor mount and, holding the tool, the motor mount is slid into the nacelle. Remove the motor mount tool and the motor is positioned correctly.
This ensures the exact same depth for each motor and makes sure the prop adapter is sitting 3.5mm in front of the engine cowl. Brilliant.
On the Cowls, the bottom magnets are installed reverse polarity to the top magnets so the cowls can't be attached upside down.
Motors installed
Great project Dave! That's a huge print. Looking forward to seeing it at the field.
The wing is complete... landing gear in, servos in, control horns on, everything centred and locked down.
RX attached, motors running, gear working, wires Y'd, rates set. The wires will need some bundling to make things easy to assemble.
Last 2 parts installed... the wing mount blocks. The fuselage is bolted to the wing mount blocks with 3 3mm x 40mm machine screws... 2 at the front, 1 at the back.
It seemed to me that this wouldn't be strong enough until I realized that it's the wing that is flying... and it's simply carrying a light fuselage.
Doors and windows decals are next... but... that's it... it's done. First nice day I'll install the wing onto the fuselage in the garage or on the driveway and taxi around a bit.
fantastic Job Davey, Looks great
Fuselage with decals. I'm not really one for decals and authenticity. I put stuff on more so I can see it than for scale... but these really do add a certain something.
Really nice Davey. Its going to be amazing to see fly.
Not sure if you saw this guy's video about his DC-6 build and fly.

Yes, couldn't have built it without the video.
That will be epic!
