Landing Gear Complete
Gear Doors are all Done
I finished manufacturing the inside of the lower gear doors, riveted, painted, and installed them. I must say it is satisfying to see something you devised years ago fall back together and work first pop.
Next is to hook up and the gear and cycle it properly (after I get the gear door sequencer working correctly), and make any fine tuning required to the fit of the doors.
Not much more to say on this really. I'll let the pictures tell the story...
It just came to me when I wasn't thinking about it yesterday, that I had not wired up the gear sequencer correctly. Instead of running the receiver to the unit, and which then connects to the air value servo and the two gear door servos, I think I just ran a Y harness to both the unit and the air valve servo. I didn't have time to check this, but this may be the source of the unit not working as it used to... I goes it had been a long time since I used it last. Fingers crossed for that one!

Wow! I've always been s sucker for a nice set of legs!
On a side note I am so excited for you that this is almost finished up, but also a bit sad. I've been silently following this from just about the beginning, and am going to miss seeing your updates. I guess you are going to have to start another awesome build to fill the void

Thanks guys! And don't worry Matt, there are plenty of places in the queue. The next will most likely be a 190D9.
Just to feel a sense of achievement, I thought I would revisit my 'to do' list...
1. Make the rear canopy attachment and install
2. Glue the canopy on
3. Make the landing light and install
4. Make the wing tip navigation light interiors and install, plus glue on the wingtip lenses
5. Get a new motor shaft adapter from Truturn. I found out mine has the wrong thread!
6. Make insides of lower gear doors
7. Make insides of middle gear doors
8. Attach gear doors to struts
9. Attach inner gear doors
10. Make trim tab actuators for ailerons
11. Final coat of paint for ailerons
12. Attach ailerons and hook up servos
13. Put on cowl checking that motor is centred
14. Paint tips of prop yellow
15. Paint prop hub yellow
16. Make tail navigation light
17. Work out how to open the battery hatch and make solution
18. Weather the wing etc
19. Make and install the guns
20. Get new 6S 5000maH batteries
22. Find a place to actually fly this thing!
23. Pray hard to a god I don't believe in
GREY = done!
I have to add this to the list too...
25. Fix bloody gear door sequencer! - FIXED!
We are slowly getting there!

I used them on all my retract birds. They are programmable via USB using a script. If you want it I can send you the script for my mustang and can modify it for timings etc
Plus they are half the price and smaller of the one you have

Wow man... just perfect
you make me sick

the lines look perfect on the gear doors..... great work

awesome, reminds me of the fiddly gear doors and gear well (same color green!) on a plastic f-84 model I never finished, and yours actually move!

A Little Good News
We Have Working Gear Doors
On a thesis writing break, I popped down and had another look at the gear door sequencer. I noticed that the LED was not on sometimes. Turns out it was a simple case of dodgy wiring on the part of the manufacturer. The signal in wire from the receiver is soldered directly to the board. They basically stripped too much insulation from the wires, meaning they could bend about and touch each other, shorting out the unit. Pulling the wires taught and separating them, then hitting the area with hot glue solved the problem...
I will post a video of the final doors working when I get time to assemble the plane again. I am thinking of replacing the door servos with some stronger digital servos to stop the buzzing... I think I have some laying around somewhere.
Thanks very much for all of the great comments guys...

Here is the video I promised of the gear doors in action. I still need to fiddle with the door throws and build a stop for the inner doors so they don't close too far (as you'll see in the video). I will make the doors open a lot more so they are more vertical. A simple adjustment of the sequencer unit when I get some time...
A Little More Weathering
I also did the exhaust stains on the fuse and inner gear doors, and cordite stains on the wing while I had the plane together. I used Tamiya smoke. A tricky paint. It seems to get a lot darker as it dries. It is semi-clear so you think you have put a lot less on than you actually have. Oh well, it is what it is!
I also put the prop on (with its fancy new yellow tips) for eye candy...
