Hi Cliff...

Cant comment on the 'World' arf as i havent seen it, but my buddy and i are finishing a pair of Kyosho F4U's and they are a pretty nice little plane. I will send some pics up soon.
The only thing to mention, inspect the box before you buy, as there is a run that has differing outboard wing colors from the gel coat. Other than that, they look sweet...

Good luck

I'm currently putting the Kyosho Corsair together. It is a great looking plane. The fiberglass fuselage and the cowl are gorgeous. The cowl itself is about 6-1/4" in diameter at the front, so a nice engine that can swing a large prop will be needed. I am mounting a YS FZ63 four stroke inverted in mine.

You should consider the GiantScalePlanes
Corsair. Despite the not all good reputation of GSP,
this one is an exception. I've seen quite a lot
at my field and they owners are all happy with it.

Thanks guy! Please keep the info and pics coming. I hadn't considered the Kyosho F4U. I checked it out on the Kyosho site. Good looking plane.

Richard L., got any pics of your YS installed? I'm gonna go with a 4 stroke. I love the sound and power.

You guys do have retracts, right? If so which ones are you using and do they handle a grass runway OK?

Thanks again,
Cliff

The Kyosho Corsair ARF without a doubt has the most accurate/ scale finish of ANY Corsair ARF currently available. It depicts a U.S.S. Bunker Hill based F4U-1D, circa 1945. The newest generation of Kyosho ARFs are also relatively lightweight for their size.
The one to avoid is the Great Planes Corsair ARF. They are of an older generation of ARFs which featured printed foamboard over wood wood construction with "matching plastic trim'. First off, the plastic trim color does not match the printed foamboard very well, but the finish is not an accurate/ scale one anyways, so the result is somewhat ugly and not very scale. Second, this type of constructione resulted in a heavy airframe, which was usually tail heavy besides.
These (Great Planse) ARF Corsairs typically weigh in at over 8 lbs RTF, which is heavy for the size. The Kyosho version, which is about the same size, will weigh in at least 1 lb and probably closer to 2 lbs lighter.
I can't tell you much about the other ARF Corsairs, except that every one I have ever seen lacks an accurate/ scale finish.

I do like the Bunker Hill scheme the best. I'm putting Hobbico 90° rotating retracts on mine. All my warbirds have retracts, and I fly off a grass runway.

I've also heard good things about the 60-size KMP Corsair, which does come with pneumatic retracts. Check it out: http://www.kmp.ca/esm/products/f4ucorsair.htm

Ah, "Marine's Dream". There is currently a full scale version of this one, hitting the airshow scene. I had not seen this ARF until now. As far as scale accuracy, looks good except for the white stripes: Never seen them on any Corsair, let alone "Marine's Dream". Can't see the underside, and whether it is white or not as the real ones are (fuselage, stab/ elevator, and center wing section underside should be white).
Very nice, scale looking cowl, I'll have to look into this one. Leave the white stripes off and it could be the new (scale finish) champ.

Yea...looks good, and is quite cheap....here anyway...

Richard...

Finally! someone else is building one of these Kyosho ships. Mine and my buddies are all but finished and due for a runup this weekend. I changed a few small things on her that i will detail with pix soon, but need to know where you have balanced yours (if you are up that far) as per this thread...

Look forward to your comments!

Hey guys, I've got one of these too. I've flown it 4 or 5 times and am having a heck of a time landing it. It either drops like a rock or floats on approach, otherwise it takes off and flys pretty well. I have a Saito 91 on it. A couple other points are :1. It likes to tip over on taxi, had retracts on initially then put fixed gear on to get used to the plane...had to bend them forward so that the axle was slightly in front of leading edge to solve taxi problem. It's also very rudder sensitive while the tailwheel is on the ground during takeoff. 2. Don't over do it with the elevator throws. Second loop I attempted ended in violent spin at the bottom (barely saved) oldtimers at my field said I had too much elevator throw and high speed stalled it.

I love the power of the 91, using a Master Airscrew 14-7 3blade. I started with the C/G at 100mm dry. I am now at 85mm and think I may be a little to far forward. It seems slightly more stable at speed but didn't seem to help the landings. Some of this is probably my lack of experience with scale aircraft, my first. I am not a novice however as I fly a Hanger 9 super stick with a Dubb Jett 50 without any problems even in moderate wind. Any feedback would be great as I would like to tame this beautiful bird.

I too have one of the Kyosho Corsairs. Hope you enjoy yours as much.

Saw the pic of your engine mounting. If I could suggest, cut or relieve the outside edges of the wood cowl mounting plate between its 4 mounting screws (4 cuts about 2 inches x .25 inches). This will allow more air to pass through the cowl. When you place the cowl in position, you can see what i mean. It's almost air-tight around the complete circumference of this wood plate.

I cured an overheating problem with the inverted OS-70 4-stroke mounted in mine.

F4U Corsair ARF?
 

JoeMamma, I will try your suggestion if the engine gets too hot. Note that I deviated from the instruction manual when I mounted the wooden ring. The flat side of the ring was mounted away from the fuselage so heat will be able to escape through the four slots between the ring and the fuselage. I will cut out the bottom of the cowl to allow more heat to escape.

I don't think this Corsair will be as bad as the Kyosho Bf109 during taxi. The CG for the 109 is only 76-mm or 3" from the leading edge, but I can taxi it and land it just fine on a grass field. I started out with a warbird and have been flying warbirds ever since, so I'm certain this Corsair won't be a surprise. Check out my gallery for my other warbirds.

Hi Guys...
Well my F4U is ready to roll... engine runup is scheduled for this weekend all going well.
Where did you balance yours?
The instructions say 90 - 110mm from the leading edge. I picked 90mm to be on the safe side until i am used to her, and have her trimmed up, but the problem is where along the Wing?
First attempt was at the wing break (approx where the scale fold is) and she came out wildly tail heavy. Bear in mind i have put an ASP .61 with Pitts muffler on a ship rated for .40 to .46)...
That cant be right.
Second Attempt was halfway along the ailerons, 90mm back from the LE and required 1/2oz to sit just nose low.
Where did you balance yours? and how does she fly? I dont want to find out at the crash site of a tail heavy warbird....
Cheers!

Always balance the plane with the CG measured from the leading edge of the wing right next to the fuselage.

F4U Corsair ARF?
 

Rich...

All my planes to date have had straight LE's so this has never been an issue. The manual shows the aileron in the balance diagram so technically its out there, but with the sweep etc...

(Once an engineering draughtsman, always.... :)

Give that a go tonight...

Balance
 

Goose,

Hope you found my comments above...I'm measuring on the inboard side of the radiator housing on bottom of wing. Make sure the wind is calm on first flight unless you're an expert flyer. As I said above, I'm not novice but certainly not expert and this is my first scale plane, warbird to boot with a full scale history of being hard to land... Also my instructions say 90-100mm and mine balanced tail heavy with a 91 4 stroke. To get it to 85mm I added 2oz prop nut and 1oz stick on to bottom of firewall and battery under fuel tank. Good luck!

SNJ, where can I check these (Graupner Corsairs) out? I didn't see them at the Hobby Lobby web-site. I hope it doesn't come with those white stripes installed, and the underside needs to be painted white, but very scale looking otherwise.

Joemamma, tell us how it fly's...

just go to graupner.com and press 2003 news.


There are som PDF files on all their new stuff.... mustangs, edge, corsair, GeeBee....lots of new stuff and stuff

RichardL,
How did you stop the retracts from twisting when down and locked? I can't seem to tighten the ball joint collar tight enough. I'm thinking of drilling and pinning or soldering the collar in place.

F4U Corsair ARF?
 

RichardL...

No doubt you have seen the drama i have had with Hobbico retracts, a lot of mucking around and re-engineering to make them work.
To stop the twist once down and the impending nose-over, lengthen the rotation link 3 or 4 turns. Fiddling with the length of the link appears to fix the problem, and also reduces the play in the main block.

Good luck

leadstk, I have posted in another thread on how to make the Hobbico retracts work. Basically, you must remove the strut from the base unit and file a flat spot for the ball join collar. Then you must adjust the length of the anti-torque link so that there is no binding in both the up-lock and the down-lock positions. When the link is at the correct length, the retract will not twist when in the locked down position.

Richard L. :

Nice set of warbirds at your "Gallery".

I rechecked your picture of the wood mounting plate. Now I see how you did it.

leadstk :

This is actually my second Kyo. Corsair. I dorked the first one last year (dumb thumbs) and busted up the 'glass fuse pretty good.

I purchased a new fuse and rebuilt the original plane during the past winter.

Flying it is great. It even has that infamous Corsair "tail waggle". Don't know what causes it.

You are "dead on" correct about the high-speed stall when applying too much up elevator at high-speed. I almost lost mine on the first flight due to excessive elevator throw.

I also fly on a grass field. To prevent nose-overs on take offs, I slowly apply throttle while holding in about 50% up elevator. This 50% up elevator is held until building up just enough ground speed. I then slowly release the elevator to neutral, watch the tail rise and continue to apply full throttle to build up more ground speed. Pull in a little up elevator and she's in the air. For whatever reason (probably the short front-to-rear wheel base), my rudder is also very sensitive on the ground. I'll need to try more experimentation with "dual-rates".

I had no luck with the Hobbico retracts on grass (too much slop and high maintenence). I removed them and installed the fixed mains. Like you did, I also bent the main gear forward about an inch.

Landing is a little tricky with this aircraft on a grass field. Especially if the grass is a little bit tall.

To prevent nose-overs, I bring mine in slightly "hot" and slowly lower engine speed as soon as the main wheels touch the ground. I don't chop the throttle. As it slows down, start pulling in a little up elevator to hold the tail down. Just remember not to pull in up elevator until she slows down. It's a little tricky to learn, but I take off and land all my taildraggers this way. Seeem's ta werk fer mee !

Like yours, I'm also using a Master Airscrew 3-blade prop (can't remember the diameter/pitch......believe it's a 13 x 8). It's mounted to an inverted OS-70 4-stroke using an ElectroDynamics On-Board Glow System. I have a couple of .60-size Mustangs with the same OS 70's using 2-blade props, and discovered a large loss of torque using the 3-blade on the Corsair. I just COULDN'T put a 2-blade on a Corsair. I spent two nights on that 3-blade prop just to add some scale realism (paint, Hamilton markings, etc.).
