I also just saw that century is offering a retractable tailwheel? Anyone know anything about it?



ziggy99 -> RE: Hits and Misses of H-9 Corsair (12/20/2003 2:31:40 PM)

What makes the Century Retracts woth $230? What is included with them and what else will I have to buy to get them working?

I have never used air retracts before so any and all info is greatly appreciated!

Thanks,
Mike

Please check my post on the new Corsair. I have a real concern for the construction of the front end of this model. While setting the needle valve at full throttle on mine, the firewall came off the plane. Imagine 11,000 rpm Saito loose. Busted the plane up real well. Nobody was hurt thank god. But a real safety problem that needs to be addressed. You could see where there were glue voids on the on the firewall. Parts have been sent back to Horizon. I truly hope John gets a look at those parts. Horizon is willing to give me a new Kit. However, I don't trust the design at this point. If John tells me they have done something to reinforce the front end, and fix the production problem, I would take another one. This one is a real safety issue.
Search jtwillie to find my post.

Everything is included with Century Jet Retracts. However, you will need to get a variable air control valve to slow down the retract operation. Otherwise, the wheels will get slammed into the wing before they have a chance to rotate completely.

Can anyone tell me how the stock landing gear on the Corsair hold up on a smooth paved runway without rocks at the over run I am talking about 1000 feet. I am going to convert the Corsair to electric with about the same or actually more power than a Saito 100. I will even be able to drive a 3 blade prop and get the same performance without too much of a weight penalty. Robart makes a decent variable speed retract valve, I will probably buy the air Century Jet Retracts and install them before I fly the plane.
Thanks Joe

PS: JT I will read your posting now.



LDM -> RE: Hits and Misses of H-9 Corsair (12/20/2003 10:31:20 PM)

Viper , I just got the plane and the stock gear and set up is first class. However I have had century in the past and i figured why invest 40 to 60 in a goo dretract servo ? I forked out the full$230 for the new century and they will be here on Tuesday . I fly off of Grass and pavemnet and expect no problem . I will keep you posted , i am not allowwed to work on the plane until after xmas because its from Santa . I was luckey to get to open it but had to close it back up after inspection .



viper21 -> RE: Hits and Misses of H-9 Corsair (12/20/2003 10:47:52 PM)

Wow thanks LDM, I am going to buy mine after Christmas and I have decided to pop for the CJ retracts and 3/8 struts because I want something with a little Cush. I am going to do the electric conversion with a motor thats brushless and geared and will swing a 14x10 3 blade prop or even larger and will swing an 18x10 APC 2 blade prop [:D] I am going to have enough power to take off and go vertical and the new Lithium Polymer batteries I will use will give me 30 minutes of flight time on one charge. But I still cant help but want to install a 91 Surpass in it. I am putting a new 91 Surpass II with a Pump in my NIB Original EZ ARF Dago Red that has the original NIP Supra Mechanical retracts the good ones with the aluminum blocks, no play at all and no longer made. Its going to haul ass. And next year I am getting a 150 P51 and installing a Saito 2.0 V Twin.[:D][:D] Maybe I will convert a 60 size Mustang to electric. See I fly both but most of my electrics are brushless powered Jets and are fast. I also have some small brushless power prop planes but nothing about 40 size with retracts. I have two EDF Jets with retracts and flaps that I am building. But I think the Corsair should get a Pumper Surpass II also what do you think?
Thanks VIper

PS: You have awesome self control by not starting the Corsair. That's how I get into these dilemmas and also having too many planes[;)]



Hellcat716 -> RE: Hangar 9 60 size corsair arf (12/20/2003 10:50:46 PM)

I would recommend the next time you but any ARF that you spend some time on strengthing the firewall. Every ARF I purchase, I spend the time doing this and I have never had a firewall problem. With all the information that has been on this forum, I am surprised that you have not heard of this recommendation. The Hangar 9 P-51 and AT-6 Texan have all had this happen to them and I have both and have not had any problems with either of them. Even though they say you can fly these planes in fifteen to twenty hours of work, I spend at least fifty hours to get them in the condition I feel that they will be ready and SAFE to fly. Remember you are the pilot in command and the responsibility is in your hands.
It says in the front of the manuel if the buyer is not prepared to accept the liability associated with the use of this product, the buyer is advised to return this kit immediatley in new and unused condition to the place of purchase.



LDM -> RE: Hangar 9 60 size corsair arf (12/21/2003 1:56:20 AM)

hey Viper your arsenal of planes sounds great . On engines i am going to make everyone cringe on this comment. I have used magnum engines for the past five years , I tried them on simple cost reason only.To my surprise the quality and relaiabilty have been great , many modelers fall into the marketing traps of the mags . All you see is OS in engines, Robart in retracts , Futaba in Radios(recently JR) . If you stray outside the line you will find HITec is great , Magnum is great and cheap, Century is best and reasonable . So for my H9corsair its a magnum 91, Bob Divey interior, full bodied pilot by Offers and Gentleman, may even paint it the three tone version of Existing Blue, White , and light Blue .panle lines and one flat spary cote to dull it up . Viper your choice of engines is also great and you cant go wrong with the pumper surpass II. I am curious on your electric conversion . I was going to convert a Sportsman Spit with a Jeti engine and Batteries . Total cost of the engine and speed control was about $250 . Not including the batteries. In FLY RC they did a conversion with a Hacker and Hecells , the batteries alone were $375 a piece -wow is that high -but they did fly a 12lb plane . I woudl love to try electric WW2 but the conversions seen so costly , any advice , keep me posted . I am also working on a p40 that is why i have the patience to not open the h9

Ok, I now know everything come with them, but what makes the worth $230? Will they hold up to the pounding of grass? Will I have to buy the struts seperate?

Please supply more info.

rcalbuquerque -> RE: Hits and Misses of H-9 Corsair (12/21/2003 4:36:37 PM)

I have put 12 flights on my Hanger 9 Corsair and so far the landing gear is holding up very well.All of my landings have been pretty smooth with an couple of bouncy landings also.I did dead stick once which resulted in over shooting the runway and rolling out in a dirt field about 60 ft with no damage. I am running a YS120SF which is about 33 oz motor and 16oz fuel tank.I also reinforced the firewall with epoxy.This plane fly's excellent and lands great with no bad habbits. I would love to install the Century retracts but have over spent on rc gear this year and will have to wait.I feel that these retracts will hold up but time will tell .Great airplane



skate5290 -> RE: Hits and Misses of H-9 Corsair (12/21/2003 7:08:05 PM)

is the corsair easy to fly because i am a beginner just about to get off of using my trainer. sounds like the corsair is a very nice plane.



Ilikebipes -> RE: Hits and Misses of H-9 Corsair (12/21/2003 9:56:58 PM)

skate5290;
I strongly urge you to master at least one low wing aircraft with speeds comparable to a super sportster first. In the meantime, you could purchase the corsair, assemble it, and fly it with an instructer untill proficient.


Would anyone be willing to get me one for Christmas this year?[:D]



rcalbuquerque -> RE: Hits and Misses of H-9 Corsair (12/21/2003 10:12:13 PM)

6 more flights on the Corsair today and everything is holding up wel. This plane is very easy to fly with no bad habbits. Just make sure balance the model correctly or she could be a handful.This plane is very fast also so I would'nt recommend it as a second plane. She also needs lots of rudder on take off.I love this plane and recommend it to anyone who wants to get into scale warbirds. Just becareful to read all the posts on assembly of this plane because there are problems with the instructions.Other than that its a fast build. I had mine ready to fly in under 2 weeks.....Lou



tophat -> RE: Hits and Misses of H-9 Corsair (12/21/2003 11:26:37 PM)

I agree fly's great but you need a lot of right rudder on takeoff and watch for crosswind it realy exagerates the torque.
Im using the saito 100 with a 14x7 3 blade.I also recomend that you doudle check the bushing on the rudder\tailweel wire good.
It has a realy small set screw and evan though I made a flat spot and used locktight as indicated I didn't get it tight enough the 1st time and it came loose after my secound landing.
Good thing I caught it before my 3rd takeoff or it could of easly jammed the rudder.Great plane[:D]



BenWlson -> RE: Hits and Misses of H-9 Corsair (12/24/2003 4:01:42 PM)

I've seen now that a few people have flown finally flown this plane... but with all the concern about the landing gear, how do they hold up on the grass??.... I fly off a fairly rough field.



rcalbuquerque -> RE: Hits and Misses of H-9 Corsair (12/24/2003 4:17:23 PM)

It would depend on the grass and how rough it is . I would fly this plane off or grass if it was golf course smooth but no way on a rough field.I have 18 flights on this Corsair with one mishap.The set screw for the wheel collar that rotates the gear came lose and the gear collapsed on take off .Minor damage to cowl. this gear will hold up for how long I don't know my plan is to go with it till I break it then upgrade to whatever is the strongest. So far it works great!



AQ500 -> RE: Hits and Misses of H-9 Corsair (12/24/2003 8:03:05 PM)

I am probably going to buy one this Saturday. The thing that scares me the most is the wing structure. From the pictures I can't see a continuous spar. Has anyone taken a closer look at it? There looks to be one right by the retract, but without a bottom chord which would severly weaken it. I would hate to see my $700 investment come down with only one wing.



rcalbuquerque -> RE: Hits and Misses of H-9 Corsair (12/24/2003 9:46:27 PM)

Don't worry about the wing it will hold up its plenty strong.I have a YS120 in my plane and it fly's at over 100mph and my wing is holding up fine. Just be sure to watch out for the rudder installation and take your time setting up the retract install. 20 flights



rcalbuquerque -> RE: Hits and Misses of H-9 Corsair (12/24/2003 11:39:37 PM)

What engine are you planning to install? I over power every plane I build I guess I just want to go fast and my field is at 6000ft .I fly the Corsair around mosty at half throttle and it still hauls and will go straight up out of sight.



viper21 -> RE: Hits and Misses of H-9 Corsair (12/25/2003 2:34:08 AM)

I am getting my Corsair after the first of the year and I am also getting the new Centjury Jet retracts. I think they will work out better than the mechanicals. Dont get me wrong I love mechanical retracts if they are good quality like the original Supra Retracts I am installing into my EZ Dago Red and will use CJM working strut oleos. Once their set up correctly they always work. But I just doubt the rotating retracts in the Corsair are of the same quality. So I will install the CJM retracts from the very start of building my plane so I dont need to mess with any modifications I might need to make after its built. I will take pictures and post them. I will get the plane the first week of January I am not sure when I will my landing gear. I am also deciding whether I want to make the plane electric or if I want to install a good 91 four stroke[:D][:D]

LDM -> RE: Hits and Misses of H-9 Corsair (12/25/2003 1:03:42 PM)

Viper , as promised I woudl update .Ok xmas day just opened the kit -simply stateded (less the excitement )its nothing but first class -worth much more the the $254 paid !
I purchased the century jet custome made gear and I have to say I dont know if they were needed.The layout of the included gear was well thought out , should be simple to hook up so its all a metter of opinion .

One thing , absolutely reinforce the inside firewall with expoxey and Fiberglass, not a critisum but a comliment to how light and clean this plane is built .I read one negative post on a weak firewall but its obvious that its built light and needs a $10 modifacation .Otherwise the opportunity to make this kit go from super to magnifiagnet is endless.

I have to finish my Sportsman P40 bash and then I am jumping right in on the H9.
On a final note the CJ retarcst arrived, nothing but quality , heavy duty and well planned.
Good luck , if you can tell me how to post pictures I will. I plan on adding a custome paint job to the H9 corsair , whit and light blue and original dark blue covering .



AQ500 -> RE: Hits and Misses of H-9 Corsair (12/25/2003 4:50:37 PM)

Thanks rcalbuquerque.

I am planning on installing the Saito 120. The fields I fly at are between 4200 and 7200 feet and hot during the summer. I have had the chance to fly the H9 P-51 up here with a 91 on the nose and I felt it was a bit gutless. (For the record my GP 40 size Extra 300 has a Saito 91 on it, it is powered just right.) I have always wondered how my planes would fly down near sea level on a cool day. I envy the coastal dwellers!

I stopped by the LHS yesterday and they have one in stock. If it is there tommorrow when they open, it will be mine. I will start to build it in a couple of weeks after I finish the Lancairs I'm working on. The engine will probably have to be a tax return day present.

I'm glad I got to this thread, a bunch of good tips. I'm going to start off with the stock retracts and hope for the best. All of the fields I fly off of have a nice paved or compacted runway.

If you plan to go with the official tri-color scheme, then you might want to pick up some reference material on the Corsair. There is nothing worst than spending all the time repainting the plane using the wrong colors.

The tri-color scheme consists of:

1) Flat Sea Blue (FS 35042) on the upper surfaces.
2) Flat Intermediate Blue (FS 35164) on the vertical surfaces and under the outer wing panels.
3) Flat Insignia White (FS 37875) on the undersurfaces of the fuselage and the center wing section.

Testors has all of these colors in their Model Master Enamel line.



WacoOne -> RE: Hits and Misses of H-9 Corsair (12/26/2003 12:50:10 AM)

I found a weak spot in the gear on mine today. On a slightly bouncy landing, the plastic tab broke off on the gear operating rod that is connected to the bellcrank in the wing. This was only the second landing and it was not hard enough to break anything under normal circumstances. I will say that the gear did not collapse even though it was unlocked after the tab broke off, saving any damage to the plane. I was able to replace the tab with a nylon one from an aileron torque rod and the gear is back operating again. This makes me glad that I put the plastic wheel wells on with small screws instead of gluing them on.

I'm using an OS 91 four stroke w/pump and a 14-6 Zinger and can take off at half throttle. The plane flies like a sport plane but mine has a tendency to dive if it gets too slow on landing. I have to keep some power on until the flare. This may be because it is a tad nose heavy. I just got a 14-7 and a 13-8 3-blade prop and I'm going to try both.

I fly off smooth pavement but I don't have a high opinion of the gear on this plane. But I'll have to think long and hard before I double the price of the plane with the Century Jet retracts.

Bill
