How do you straighten a fuselage on a Edge 540

Hey fellas,

Need some expertise in kit building. I'm putting together a Radical Edge 540 and the fuselage is warped about 5 degrees to the left. I didn't really notice till after I painted it with magic markers. I'm sure it will affect flight, so can I put a little water on the right side and put it between some books or something? It's warped from the cockpit to the nose.

how about spraying some water and then using a sealing iron to heat flatten it?

I would spray water on it and then weight it down while it dries. I've never tried the iron method, that might work. Some people also recommend using Windex instead of water.

You say it's bent to the left. In that case, you'll want to put the water on left side because you want that side to expand. I'd actually just soak both sides.

The reason they say Windex is because of the ammonia. You can get the same reasults using ammonia and water. Ammonia will soften the fibers in the wood and make it easier to bend.

So if it's bent to the left then soak the left side? That will make it expand? I'll give it a try.

Yep. The idea with wetting one side only is that the balsa will absorb the water and expand. If it's curved to the left and you wet the left side, the left side will expand and force the tip and tail to move to the right, thus straightening it out.

thanks for the suggestions. I'll give it a try.
