Started on my Extra 300lx tonight and when the stabs are inserted in the fuse there is a 1/8 or better gap at the rear of it between the stab and the fuse on both sides, and the right side alignment dowel is loose fitting. The hole in the fuse is too big so I can move the incidence of the stab about 1/8 up and down.
I was also missing the manual, anyone have it online so I can download it? I didn't see it on their site.

Anyone else have these problems?

There should be a manual on the wildhare site. The Extra's and Edge's have the same sequence so it should be on the download portion.

Thanks, I didn't realize the manual was the same for the edge thats why I didn't see it.

Still have the stab problem though.

I would check the spar tube length. I had a similiar problem with a set wings from a different model. Slide the tube into each stab separately and make some pencil marks on the tube were they bottom out. Now reassemble on the fuselage. If the stabs are making it to the marks you made but you still have a gap, shorten the spar tube just slightly more that the total gap. Use a tubing cutter to make a clean cut without distorting the shape of the tube. I took about 1/4" off of my wing spar if I remember correctly.

Whats causes this problem is two things: either the spar is slightly to long, or more than likely, there a gob of glue that seeped into the end of the tube socket during assembly.

Hope this solves you problem...

Na thats not the problem. I can put just one side in and it doesn't fit flush.
plus the hole for the alignment dowel is too big so The incidence will be off. Anyone know what it should be? 0 everything or ?

Incidence for everything on the plane should be zero. It's not uncommon to have to adjust the stab incidences a little. The set screws for the stabs will hold it all in place once you have the incidence correct, if it needs adjusted. Most never take the stabs off once they have been installed, so it's no big deal. Use the top edges of the canopy hatch opening for an incidence reference. Look at it this way, you won't have to open up the holes to adjust the incidence. Look at all the time and work you saved.

If the gap doesn't want to go away, it still won't hurt the flight traits at all. Check the stab tube again, though, I had to shorten two of mine about 1/4" too.

It isnt the tube length, I can have the tube stick out 2" and put the stab on and it still has the large gap, I wont fly it with that large of gap as it is ugly and not the best thing to do. It is the angle of the tube itself that is incorrect, I may just bend it backwards a little bit.

From the pics it looks like the insert in the stab might be a little off. I would speak to tom personaly about that one.

I was plannig on calling tomorrow.

Yes, do call.

This is not an incidence problem. To me it looks like the fuse is off center. put the wing tube in and the stab tube and measure them center to center ( EQUAL ON BOTH SIDES ) and measure from the tip of the wing tube to the tip of the stab tube. if they are not equal. your fuse is not center.

put both tubes in and measured from the outside of tail one straight up to the wing one, it is 1/8" off on the right side.

I have a 1/16 gap between mine and the lenght from the wing tube to tip is a 1/16 off, but it dosnt affect flite performance. I left it alone thinking it will loosen up a little after a few flights, and it fit better as time went on. Mine were very tight when installing and after a little pushing on they came together. Yours has a pretty big gap have you talked to Tom yet about a solution?

After talking with Tom I decided it was easier to fix it rather than have new parts sent. I sanded the inside of the wing tube on the stabs and that seemed to get rid of most of the gap. I may still bend the tube slightly also.

Bend the tube. [>:] What kind of a repair is that

Boy I just ordered a 540 today. Hope i dont have to go thur this.................Infact i wont

FYI, I offered to send replacement parts, and I also recommended against bending the tube. He felt it was faster and simpler to do the repair himself.

Seems to me, and I am not the most experienced builder here, but bending the tube may induce unforseen issues with incidence..

Its not going to be bent up and down, only backwards a little bit so incidences wouldn't be changed. I was also told that it would be fine to bend it as long as I didn't plan on removing the stabs often. Im sure with the small amount though they could still be removed.

It wont really be bent, more like massaged as it wont take much, in fact they fit OK now, But I don't want the stress on the ply tabs from the bolts pulling it in constantly thats why I want to remove some pressure from them.

I was talked into doing the repair myself really, Which I agreed would be faster.
