While working with the flaps I didn't like their simplicity:





So I decided to add some details:

Finished product, not fully to scale but for semi scale model it looks better then before - I think...

Wow! Your Zero looks awesome Darod!
I pulled the trigger and gonna order the Zero myself this week. You’re Zero will be a great inspiration to mine.

Still undecided if I have to order the 2 or 3 blade spinner. I’m gonna use a Saito FG90R3 and due to “noise restrictions” on our field, I’m leaning towards a 3 blade prop. I read that the Biela 22x12x3 “semi scale” seems to be the perfect combo? Any thoughts on 2 blade props noise versus performance?

Landing gear clamshell door test:


Next step is some painting and weathering to the underside.

Great work! I like what you’ve done with the gear doors.

Thanks!
I hope it will work during the flight. My concern is weight of strut with the wheel - 460g. With additional load from clamshell door spring and wind force it will be hard work for my retracts - Electron Evo 40.

Slight weathering, I wish to add more dirt but for sure Saito will do...​​​​​​​

Excellent job on the Zero. Not many of us have the patience to add all those rivets and details. I thought mine was over the top...yours is on top of the top.
REMEMBER: "The plane comes 95% complete" Ha, ha, ha!

It looks like you added engine baffles. They should be 60% back from the front of the heat sink.
I can't tell from the photo. Did you open up the cowl flaps a bit? Also a must for extra exit air.
I would add heat telemetry. Nice to monitor while flying. Should be around 220F when cruising around. Over 250F is heading towards over-heating.
I would add RPM telemetry. 6600 rpm is the sweet spot for sport and scale flying. If you push the engine, you won't see a significant speed increase.
Did your Saito get any of the Ray English mods?

Hello, I have been in this hobby for 30 years and it is the first time that I have been releasing the FG-90R3 engine, the ignition burned. It started to smoke and now it smells like burning.I want to know if anyone had this problem

Hi and thanks for your appraisal. In fact all what I've done so far is thanks to you....
When I saw your plane first time in this thread I went speachless. Then I knew this model is worth to make all those extras to achieve such a scale look. Thanks buddy...
I did cowl flaps operable with 2 servos , so can be opened widely to allow air flow. I have also telemetry with temp sensor attached to top cylinder, rpm sensor too. Thanks to you input regarding temp. I will monitor situation to avoid overheatng my Saito. I don' have Ray English mods. I don't think that those are required at the moment. I like scale flying so top speed is not what I'm aiming for. I'll adjust H needle to make carburator setting as rich as possible giving still enough power to fly. I hope to make maiden flight in June. I'm working at sea now so spending 3 months on board will be enough time to make some progress with cockpit.

Good luck at sea. I built a box for my cockpit. Wonder if you could take the cockpit with you while deployed.
Engine should be fine without the Ray English mods. Baffles and opening up the cowl flaps should keep you running great in the air.
Can't wait to see it fly.

I hope it will fly as good as yours. Especially during last Scale Masters it was very scale flying, take off and landing beautiful.
How do you find landings? Is it a challenge to make 3 point landing with this model? All movies I saw so far there are landings on main wheels mostly
I wonder if this is because of high wing loading of this plane.

3-point landings. So much depends on the plane. Most RC warbirds I've seen land on the mains. You need to be super skilled to land a heavy rc warbird in 3 points.
I did a little research. (I'm no expert) It seems 3 points were used in short runway situations. During the last few feet the plane gently stalls onto the three wheels. The warbird is still flying when landing on mains only. Carrier planes like the zero and corsair appear to stall onto the deck in a 3 point profile with the tailhook catching the wire. This is probably why carrier pilots are some of the best flyers.
I'm building a TopRC FW 190. Found an interesting interview with a German pilot from WW2 who flew this plane. He said they ALWAYS landed in 3 point. It was a sign of great skill. Mains only was looked down-upon. Gotta love those Germans.

Thanks for your reply.
It looks that model will stall too while on angle for 3 points landing shortly before touch down, hopefully not much before.....
Let's see, it has to go to the air first...
Best regards.

Thanks! The only problem is the magnetic compass deviation...more then 10deg to the East.
I have to make compensation😂
