Lee,

Might also be useful when flying indoors, but I've found spoilerons to be better for that. For the Mossie, I programmed a 3-way switch with 15 degrees of spoilerons, none, or 15 degrees of flaperons. The flaperons made it much more difficult to fly slowly. They made the plane very prone to tip-stalls, and low-speed aileron authority was pretty much non-existent. In contrast, the spoilerons very noticeably extend the lower end of the flight-envelope. They allow for great roll-control at very low speeds & at high angles-of-attack. They dramatically improved low-speed maneuverability. I use the spoilerons when flying in tight quarters, like when we only get one indoor soccer court at our winter flying spot.

If I remember correctly, someone extended the leading-edge of the wing of the UM Sukhoi to slow it down for flying in cramped quarters indoors. Might be an option for your backyard flying.

It saw extremely tail heavy I added the dime and 7 lead shot to hit the CG.the stock prop has plenty of power to fly indoors. it was a little fast for the gym. I then dropped in 30 degrees of flaps . Just what to docter orderd. with the extra drag it slowed down . I added 10% down ele trim to keep the nose down .I'm useing a DX6i transmitter.

The Hate! there were 3 other Corsairs there they ALL looked the same. But it flies so well I decided to repair the crash damage and repaint. I decided on the AU-1 1956 version . Yes I know that all the AU-1 went to the Marines. BUT I have a photo of 4 AU-1s setting on the ramp with NAVY painted on the aft fuse.

WOW!!!! That is nice looking!!! I really like the exhaust!! That looks GREAT!!! Glad you didn't rip into her! Wish you could paint my full-size PZ Corsair in that scheme..... even the Ottumwa is cool lookin! Gotta sport where you're from!!

The flaps were done with the Tx .the linkage rod was moved to the 2nd hole closest to the control horn pivit point.

the flaps let me fly in a smaller space .As with everything to do with flight there is a trade off . I don't think I'll be going to many loops with a 40 foot ceiling. because of the increased drag you have got to use a little more power . this cuts down on your flight time. you let the nose rise and you stall quickly.

Ottumwa Naval Air Station closed in 1946 A lot of navy pilots started there

Deflecting the ailerons up instead of down will allow for slower flight and it will be more stable and easier to fly.

When the tips are deflected down, they can stall before the root, and the plane fall off to one side or the other. With the tips up, the wing root will always stall before the tips.

The plane will fly with a higher AOA, which produces more lift and Drag.

normally I would agree 100% but my corsair shows no sign of wanting to tip stall ! it might be a combination of the undercambered wing and the wing tip dihedral.

I do most of my flying in town and this is my second biggest fear, next to having the plane go out of control and hurt somebody. There have been a few close calls with stray dogs and one of these days...

Did you see it coming? I got a fair bit of practice at hand-catching planes this winter, when the snow was really deep and I didn't want the electronics to get wet. I figure it might be a good option for that day when a dog comes out of nowhere and there is only one thing on his "mind".

With my Champ at the park, I found it easy to fly low and let the dogs chase it across the park and then hurry back after I've worn them out. Put a little high speed distance between them and your landing.

Looks great, Paul. You may have seen this one:

I think it looks great as well, but I like yours even more.

I've been thinking that Parkzone would do well to offer some alternative paint schemes for many of their planes.

Awe man, after all that you've done to get her in the air. Not sure if I'd rather have a crash or have the dog eat it??? Sorry to hear 'bout that. Hopefully you'll be too busy flying the Carbon Cub SS (or MiG?) to keep your mind off the Corsair???

Yeah, I want the carbon cub, but I was told "no more planes" today, so I think the carbon cub is gonna have to wait.

that corsair was flying so nice to, it went where you pointed it, was very predictable, the power off glide couldn't have been more perfect.

I just couldn't outrun the dog, no matter how hard I tried, that dog is one fast SOB, I flew the plane to the far end of the field, did a 180 degree turn, and flew it back as fast is it's little motor would haul it, and it just wasn't fast enough, the dog was literally under it the entire way.

yup, I'm really disappointed plus I'm told I spent to much already so I can't have another one, so I guess I'm just gonna have to rebuild this one again.

on the bright side, I learned a few things during the previous re-build, so for the third time around, it oughta come out dang near perfect, even better then before.

That just breaks my heart to see a plane in that condition

I ran into that situation once with a really fast dog. There were some kids who tried chasing the dog and calling it off but it was so determined. Then luckily it's master came out of a house and called him away with the voice of authority. If that ever happens again, and it's too fast to hand-catch, other options might be parking it on a roof or in a tree.

...or flying it out over a busy street, assuming it's not your dog.

Just kidding. Who would think of such a horrible thing...?
