I flew mine before doing any painting, weathering, or detailing, then added that after I had it dialed in. I also added a smoke system you'll see in the video.

I have about a dozen flights on mine now and the Saito FG-90 is running perfectly. This is the first time I've used one of these engines and I was a bit skeptical about the reliability, but it runs very well.

So far the stock gear and controller are working well with no issues. I replaced the springs in the struts and removed the super sticky grease and they work pretty smoothly now. I'm using the gear controller to sequence the doors, but that took some time until I figured out that the gear wires have to be reverse polarity to make the sequence work correctly.

Here are a couple photos showing the detailing. A friend made the air intakes and did the weathering, he is very talented.

The last thing I've done is add the numbers. I still want to add guns in the wings.

Here are some photos of the reinforcements I added. The plates in the gear wells are glued with Hysol along with the screws.

Nice job, I have probably 300 flights on my H9 Corsair with that engine, it's been running like a swiss watch

Default Flap hinges 3 different sizes, what goes where?

I have tallest hinges on largest flap but had to mix medium and shortest on other 2 flaps to get trailing edges and front side gaps to wing all even. Have the rest of you had to stagger hinge sizes also?
please email response

Any updates? Has anyone else flown his? Has Top Rc done any new real improvements on the wing design? I have not yet been able to fly mine, but a friend that made my wing mod on his did a few weeks ago, flight was not very long, so he did not push the machine, but had a less than perfect landing that would have definitely broken the original wing, his had no issues, so far it would appear the mod performs as needed to correct the design flaws, we’ll see…

I did the center section mods on mine very much like jlorenco did to his . The plane flew fantastic , but on the last flight the lower part of the right strut folded on run out after touch down and dug in . The plane nosed over ever so slowly but hit the top of the rudder and verticle stab and broke the tail section . The tail is repairable but its going to take some work to get it back together. The lower leg of the strut has very thin wall so be warned to those using the TopRC landing gear. I will be going back with Robart gear after I repair the damaged tail .

Question on engine thrust offset:

The instructions say to "maintain" 2.5 degrees right thrust and down thrust. A rough check seems to show there is no thrust offset in the firewall - it's zero/zero. How is everyone installing their engines - adding right and down thrust manually or just bolting to the firewall as is and going with that?

Thanks--

Bryan

I added spacers behind the engine standoffs on mine to get some offset. I didnít use the full 2.5 degrees but closer to 2 degrees and it flies straight without any noticeable change in trim with changes in power settings.

Cool, thanks.

Did you add down thrust also, or just right thrust?

I added both, closer to 1.5 degrees, because 2.5 looked like a lot.

Good luck with your build and post some photos if you have a chance. Just flew mine last week after a rather long hanger stay and this plane is one of my favorite warbirds. Flies so well (for a Corsair anyway) and looks very scale in the air. The biggest recommendation I can make is to keep it light!

I enjoyed your flight videos and pictures. That's a nice looking and flying Corsair. Motivating! Did you add guns yet? I'd like to see how you did that. Also, where did you mount your smoke oil tank?

I'm working on a couple of "light" things. First, I did cut the wing open from the bottom and added a full depth ply spar between the existing so called spars. That added weight, but a good mod I think.

My biggest attempt at lightening was moving the elevator servos up to the plywood tray in the forward fuselage. Metal gear servos are about 2 oz each. So that's 4 oz not in the tail now. At about a 4:1 ratio that's 16 oz that won't be needed in the nose. I'm sure it won't work out exactly that good, but it can't hurt. I changed to a lighter tailwheel that saved about an ounce also.

Still working on it so we'll see how it turns out.

I havenít added the guns yet, I got side tracked with some other projects but itís on the list. My smoke oil and fuel tanks sit side by side in the fuselage under the forward end of the wing. The Saito R90 just sips the fuel so I didnít need a very large fuel tank.

I think thatís a good move to get the elevator servos out of the tail. I used small but powerful mini servos in the tail for the same reason and didnít need to add any weight to the nose, but I did push the engine as far forward as possible while keeping a reasonable gap between the cowl and fuselage.

Do any of you have a pic of the radio install. Receiver, tank, batteries and such. I see the wing has a cut out that looks like some stuff could be put there as well.

Here is my setup. The batteries sit on the tray in the front. Fuel and smoke oil tanks are under the radio equipment tray where the wing has the thinned section.

Tons of room, it's much easier to load up than some planes. Here's how mine looks.
