Hey or Hello Im new to this post just bought my first GP Corsair . I have a couple Parkzones P-51,Spitfire Im a WARBIRD FANSo this is my first ARF I have read a couple pages of this post and it sounds like this plane is a great plane it also has alot of strength issues.The rear stab has anybody thought of taking the monokote off and reinforce with a flat piece of carbon and then redo the monokote?The monokote job on this plane sucks I dont have that much knowledge about this stuff but when I opened my box I was shocked at the POOR QUALITY OF MONOKOTE JOB [:@]I was thinking of stripping whole plane and doing it myself and that way also I could reinfoce what needs to be done and put landing gear on this bird.And I was going to put the O.S .25 on it or maybe Electric. Anybody done a electric conversion of this plane and if so what did you put in plane?Im not going to go CRAZY with this bird like some on this post"And I dont mean that in a bad way" Im new to flyn so I want to take it easy for awhile and then maybe speed things up.

Deadroman, in the video your engine is too rich. Also if you are having a snapping problem, add nose weight or shift something forward. These little scale aircraft do not require a lot of elevator travel and I believe anything over 1\4" is too much.

Yeah, that will do it too. Hope she flies better after the fix. I lost a servo in midair the other day. The left aileron went out, but fortunately stopped in a relative neutral position. It took a second to figure out why the roll rate suddenly sucked! Made a successful landing. Just have to order some fine Hobbico servo gears.

With the inverted .25, how high is the tank in relation to the carb center? Any problems with this? I just watched a video of this and it looks like too much fun!
Thanks

With it inverted, the tank sits quite a bit above the carb. Doesn't cause any problems as long as you tune it with the plane right way up. The fuel will siphon if you leave it sitting with a full tank. I just keep it inverted until I'm ready to start it. Yeah, the combat corsair is a ball to fly, but you have to be on your toes. It flys fast and is very responsive, even on fairly low rates. Just make sure you are using good quality servos, preferably with metal gears, especially for the ailerons. For the money, it's a lot of bang for buck. A ball bearing 25 is all the engine you need.

WMB,
Yes to the previous reply. I have to start the engine a little nose high, but once it's running it's fine. I'm running a OS .25 and it really scoots. It'll even be able to handle those dreaded Great Fallsian winds! I spent 5 years up there, living at Malmstrom.

And a couple of other things - it's worthwhile doing the rudder mod as long as you haven't glused in ther vert stab yet. Just cut out a rudder from the stab. cut vertically from the rear point where the vert stab is glued in (that will make sense to anyone who has a gp combat corsair). I did the ruddr mod and found it well worhtwhile.

the servo mount plate and pushrod tubes are pre-installed and the pushrod wire is supplied with the kit. This plane can be launched and flown by 1 person - just be ready to get back on the sticks as soon as you've thrown it. Mine always takes a dive towards the dirt straight after launching, but then it is away flyin.

Have fun with it. I'm sure you will unless you crash it first

wow guys. It is really a coincidence that I happen to own both A corsair and mustang great planes combat planes. Are you ready for this... I just purchased the corsair, used and the guy shoehorned an os46 in this corsair. any thoughts. Its obviously nose heavy, but beyond that I just know how fast my mustang is with the osfx25 on it. will this corsair even fly???? The reason I even consider leaving the 46 in, is because he did a great install job. it has a pitts muffler that points neatly out the bottom. He swears hes flown it and claims, " you never use more than half throttle" please avise. thanks in advance!!! Ivo

well guys, Im too new to even have a humble opinion yet but no one even answered my post... no sweat. I guess if thats some kind of initiation im game???I will just keep posting like a ghostwriter. Anyway, I flew the heck out of my 025 size mustang this weekend, and so far I love it. I guess ill wait till I master the speed of it before I try my great planes corsair with the 046 os max on it.

Hey Ivo. Welcome aboard. I'm glad to see you've got a couple of planes that are many peoples favourites. The mustang and corsair. And these 1/12 renditions are at the top of the heap. Forget .40 sized ones (despite what you have mounted) these GP ARFs are just sooo cool. I am in love with my corsair. My wife gets jealous.

Way back in this thread there is a guy who put either a 40 or 46 in a combat corsair. But never really went on to explain how insane it was. I'd be keen to hear. I fly mine with an ASP .25 and its crazy fast. But I got about 4 oz of lead in the nose to balance it. I've been wondering if this weight might be put to better use in more engine capacity. Let me know how your corsair flies with the .46. I'd be keen to know. Remember, there is always the throttle stick. You can turn your .46 into a .25 simply by pulling back on that stick.

Just make sure you got good metal geared servos all round and take note of all the advice in this thread about protecting the aileron servos on landing. I'll preach again about moving the aileron servos on the corsair from underneath the wing to the top of the wing. By doing this, it means that you can actually have a second flight on the same day no matter how smooth your first belly-landing is. Those servos sticking out the bottom of the wing WILL strip the plastic gear. Unless you belly it into a tarmac runway. Then they 'MAY' strip.

Have fun with those planes. Any chance of a pic of the .46 stuffed into the corsair cowl?

To post pics, first hit the 'reply button in the top right corner of the previous post (i.e - don't use the quick reply box at the bottom of the screen) A new window will open up and you type your reply. In the lower left corner of this window is a link that says 'click here to upload images and files'. Click on this. Another window will pop up and let you select images from your hard drive. Select the image you want and click 'upload'. It's pretty self explanatory from there.
This is a pic of mine. Shes a bit more battle scarred now.

I wrote a long time ago in this thread about putting an OS46 in my combat corsair . My first one flew like a dream , but it took awhile to get the take offs down , really nasty snap roll to the left on takeoff . I will describe our fix later . My first corsair went in when I dunb thumbed it while flying about 4 feet over a barbed wire fence . My bad , not the airplanes fault . My second corsair is still curently flying great . It also has an OS46 in it. I usually fly flat out the whole flight . Seems the spectators really enjoy the speed , and so do I . These planes are surprisingly tough. Make sure that you build the plane bearing in mind that you are pushing the envelope . When you over power as previously mentioned metal gears in your servos are a necessity . I also remove the covering on the stabizer and laminate 1/16 plywood and then recover , before I install it in the plane . I fly at a grass field and have had many , many flights with both planes and have never had a problem with the servos mounted under the wings. I understand landing on a hard surface is a different situation . I have never had to put weight in the nose , probably because of the larger engine . I also install a larger fuel tank . My buddy has an OS32 in his corsair and is also extreemly fast . The size of the engine has never been a problem for either of us . Like the previous post said if you don't want to go fast , throtle back . OK the take off fix. we have found that by holding the plane at a 45 degree angle and a slight tip to the right , full throttle and a good push , we have had so far 100 percent good take offs . B/4 we have had moderate luck with other methods , but in our case this is the best . I don't know if this is necessary on a plane with a 25 or smaller engine , as all the corsairs I have seen fly in our area have at least a 32 in them .

wow, corvett that makes me want to keep this 46 osmax in my corsair. I have a mustang with a 025 in it and have held off either flying or removing the big engine. You see it is wintertime in rockford and dont get to fly much outside..... this really gives me hope. thanks ivo

Looks like a tidy installation. 3 bladed prop looks cool too!
What muffler set up are you using?

thanks for the kind words, but as i told you guys i purchased the corsair with 46 engine already installed. It does have a really cool pitts type muffler and just two little tubes stick out the bottom to really set off the job! I will send a picture or two from bottom vue to show the exh. ivo

Just out of curiosity, why would someone even need to put anything bigger than a .25 FX in there? These planes are so lite that they fly so fast as it is. They literally fly out of you hands with an OS .25FX and a bisson pitts muffler spinning a MA 9x4 at about 17000 rpm, and you can do continous loops until you run out of of fuel. We've clocked coro versions of these at close to 80 mph, and they are heavier birds as well.

In combat (aside from the fact that you cant fly them in 2610 with a .46) you'll find that any added speed is actually a setback, as you'll find youself constantly overshooting your prey. You'll end up flying at half throttle 90% of the time. Great for evading cuts, but you wont rack up any more with the added speed.

So having said that, at $40 more per engine, and no net advantage, to what ends would you wanna fly with a .46?
