THANKS

Tater, this is really not much different than a built up wing having strength issues with retracts installed. the weakest area of most wing structures, most will agree, is in the retract are PROVIDED that there have been no mods or strengthening work done. Iam currently building a TF.60 P-47 and the bays around the retracts didnt look strong enough for me so Iused some spray foam in those bays after sealing them off to help add strength. Ihave no experience with park flyers and none with foam so Iam sure that a guy with knowledge in that area will have some encouraging words. if you cut away an area of a wing like that, its bound to give up some strength.. sometimes its nearly insignificant.. other times it can compromise the structure if you did some major surgery.. I wouldnt think you would have significant issues if you go that route.. just my 2 cents..

I have not seen anyone flying these with retracts.  If you don't like the fixed gear, just put the skid plates on it and hand toss it.  It flies like a dream, don't ruin that by adding a bunch of weight.  Plus you have to add a retract servo...yada yada yada.  When you start carving that wing out, it should be fairly obvious that you are removing structural material.  The wing must support up to 5 or 6 times the weight of the entire aircraft once airborne and you start putting it into high G maneuvers.
Good luck.

I personally don't think WWII warbirds fly that well to begin with. You really begin to notice the heavy wing loading after flying a nice, low wing loaded plane like a Stik or 3D bird. Adding retracts will only make it worse. If you are looking for that clean look with gear up, go with a P51BL from Parkzone. It'd designed to belly land and is reinforced in the proper areas from the factory. You just hand launch and your away. It's lots of fun, nice, and moderately quick for a little foamy.

PS....retracts are a major pain the butt IMO. You will always be messing with them.

ok look i just wanna know if the wing will break not how much of a pain retracts are

thanks

The Parkzone Corsair is designed to be a low-cost lightweight replication of the gull winged WWII fighter. They wanted to keep the plane lightweight and simple so that it was easy to use and therefore would appeal to a larger range of people in the hobby. One of the ways that they achieve this is build a simple lightweight foam wing structure. In bigger replications of the Corsair the wing will consist of a built up structure that supports the weight of the plane and also allows for retracts to be used as the structure of the wing will absorb the weight and pounding the wing will take. The Parkzone Corsair doesn't come with retracts because the foam of the wing needs to be one-piece in order to keep it lightweight and still support the flying weight of the plane.

Now does this mean you can't cut into the wing and install retracts? Not at all. It's your plane and if you want to cut the wing and put retracts into it the by all means do so. But one of the goals of the Beginner's Forum here on RCU is to help educate new people in the hobby with the problems they may face in situations such as this. And that is what these people here are doing. They are simply trying it let you know there are likely to be problems with what you want to do. Yes, you can cut the wing and install a set of retracts. However, as I said above the entire piece of foam is the structure of the wing, and when you start cutting into that foam you will be weakening the structure of the wing which could very easily cause it to break. Yes, you can add material and reinforce the wing to help keep it from breaking. But everything that you add is going to add weight to the plane. And add in the weight of the retracts and you could add enough weight that could very easily make the plane difficult to fly. Warbirds normally have a high wing loading (meaning the amount of weight that the wing supports), and that usually scales down to models. When you add weight it can add bad handling characteristics to the plane. Another thing to think about is also the fact that the wing is very thin to start with. Even experienced modelers would have a hard time accurately cutting the wing to install retracts, and a cut in the wrong place could very well ruin the wing to where it would be un-flyable.

As I said above, nobody is telling you that you can't do this. I'm sure there may be people out there that have added retracts to this plane, so it's very possible that it can be done. All I am saying is that the members of this forum are simply trying to outline the hazards of what you want to do in order to educate you so you can make the decision to do this based on all the information on this issue. But ignoring the warnings and fishing around for the answer you "want" to hear isn't going to change the fact of the matter that this may be something that just might not work out the way you wish it to. Regardless of what you may think right now, the members of this forum want to see you succeed. Many of the more experienced members here are some of the best modelers and pilots in the hobby today and they are here because they like to see and help new people get started in this hobby. Many times new people will get a bad piece of info that could cause them problems, and the experienced members of this forum are here to help point out things that could cause problems with what they are trying to do.

Hope this helps

Odds are it WILL break! Now move on to one designed for retracts.

RE: will the wing really break???!!!!!
 

No, it will not break. You should do it, and video the maiden and post on you tube please.
And it will look nice, and it won't add any weight, and you will find a perfect place to add the retract servo right in the middle of the wing, and cutting out for that won't make it any weaker either.
I think that is really what you were wanting to hear.</p>

RE: will the wing really break???!!!!!
 

Nice sarcasm, my fellow Texan.

To the OP, a lot of that depends on how you fly. If you're a good lander and you don't get out in gusty winds and do a lot of jerky maneuvers, then you won't put much stress on the wing. But if you fly it like most of these foamies get flown (hard) then your chances aren't so good.

RE: will the wing really break???!!!!!
 

ok i guess it would be a better idea to just put the included skid plates on the plane

RE: will the wing really break???!!!!!
 

I just want to show you why I said what I did. Keeping in mind that a Corsair has to fold the gear rearward, here is what the cross section would look like:

RE: will the wing really break???!!!!!
 

wow that would make the wing really weak and sorry for acting like a 3 year old asking for advise than not taking it

RE: will the wing really break???!!!!!
 

Don't sweat it. We all were beginners at one time and every one of us had ideas of what we wanted to do, some good and some bad. The important thing is that you are asking questions and listening. I hope you enjoy your Corsair.

Ditto!
