I'm at the stage of installing the oil coolers (plastic part) in the TF Corsair 60 and find that they were not included in the box. Not wanting to pay $12 for two little plastic parts, I'm resigned to carving them out of some balsa.

At step 34 it says that a lot of wood needs to be carved out of the wing to fit these plastic parts in. Not having these parts leaves me wondering just what shape the underlying wing needs to be to accept a carved oil cooler.

Can anyone give me some guidance? Maybe photoshop this location indicating what the shape should be? Or close to it?



Thanks for any help.

dont be cheap get the correct parts so you get a good looking and scale shape

There's that to consider too [:@]

Are you building a 'red box' Corsair? They did not have the molded coolers.

If you look at scale 3 view drawings of the Corsair from above, you should notice that the coolers are recessed into the wing. At 1/8 scale, they should be about 1/4" back. This is nearly impossible with the Top Flite Corsair wings, as you would need to remove much of the leading edge 'spar'.
BUT, I DO attempt to move mine back some, by sanding the inside of the coolers (on a flat sanding surface) so thet I nearly sand thtru the 'vents'. That allows the cooller to be mounted farther aft, so that I can get at least SOME recess.

Hi Voyager,

I don't know if this helps or not as I'm not at the point of installing my air coolers yet and I'm making substantial modifications to the internal shape and the LE design to accept them. This may give you a basic feel for the shape. As far as I can tell, the major balsa removal will be shaving back the sheeting and LE to get the flanges of the plastic part to recess flush with the wing surface. For those that may be wondering, I replaced the balsa LE Triplers with 1/8 Lite Ply allowing me to cut out the recess for the vents. If I need more strength, I may add a strip or two of carbon fiber tape later in the build, but I think it is going to be fine as pictured. Still in the very rough phases here, so apologies for the unpolished bits. Let me know if there are other angles that would be helpful to you.

These may help you as you draw your profiles for your carved bits.

Thanks for the hints folks but it was a stupid idea on my part.

Trying to cut slots out of balsa is well, it's crappy. As you slice through it, the piece is so small, it fragments and looks terrible.

I'm not going to try slicing wood to get them to look good. They just won't.

If you call them and tell them they were not in the box they will send them to you for free. I accidentally cracked my canopy and told the girl I did. I was going to pay for another one and she told me that she would just send a new one to me free. They are real nice people and want your continued business.

EUREKA !

Good thing I'm married to a wonderful girl. I've spent 2 hours searching for those things and she comes down and HERE THEY ARE SWEETIE ! [sm=bananahead.gif]

Boy are they big. I see the lines where they are to be cut but still......

Thanks for taking the time to help me. I can now use the pics/ideas posted here to help me get them setup more scale-like.

Len,

Glad you found the parts. I'd have sent you the 12$ to get them LOL

You need to remove a TREE'S worth of balsa to get them to fit properly. Go slow and keep checking the fit.


Happy New Year to all

I've cut them to the lines and have tried to fit them b4 the trimming. It does seem an awful lot has to be cut away. It's going to be a slow process (as you suggest).

voyager_663rd

OK. Got one done but I don't know if it can be done better. Here's a pic of it in "final position" (just held down).

Question: is that as good as I can expect (and the gap being filled with filler) or should it be "tighter"???

That's about the point I Stopped and then I used some 1/8th balsa to insert there and sand to shape. Can't even tell once it matches up to the fuselage after the wing installation,....

Had to hack away quite a bit of wood for mine,... more that I thought initially.

voyager_663rd

And that's what puzzled me about this "chopping". My experience was not much at all had to be cut away. The biggest concern I had was getting the edges flush with the sheeting. With only 1/16" to work with as it is, I went through in a couple of places.

Can't see how you can get a rounded piece of plastic to fit over the flat l.e. when the sheeting needs to be cut back too.

Thanks for the tip to leave it as it is now and just fill it in/bevel it off.
