Hi there,

You wont think of me much after you read this...[:@] but I just have to ask!!!!!

I just glued the fin to the fuse of an Extra 300 and the fin came out a bit to the right - not 90 degr' to the body.

Now its only slightly off, maybe 1 deg or so... but its glued with epoxy so I don't think I can remove it without destroying the lot.
I think the only way to fix this problem is to tear it out ... or to cut it off and remake the piece and ... well you know...do it right

Is this a big problem or can I leave it be....???
I looked at it with the rudder on the fin and the rudder's bottom is 3mm' to the left from the center line - but it does not reach the right end of the fuse'...

I really don't have any clue on what the he*l I should do here

Please help me on this guys...

Thanks

Sometimes, you can use your heat gun to soften and release the epoxy.

It's a big problem if you want to fly precision aerobatics and have the skill or want to develop them with this plane. It won't ever trim perfectly, but it will fly and 90% of all R/C pilots in the world probably wouldn't be able to tell the difference.

But you can fix it easily enough. Either cut it off, sand the fuselage and build a new fin or try using heat. Problem with heat is you may melt the covering trying to soften the epoxy. Also, if you do heat the epoxy enough to soften it then you might destroy it's strength, so you should probably heat it enough to remove the fin, sand off as much epoxy as possible and glue it on with fresh glue. A toothpick or three to give it more strength might be a good idea if there's still a lot of the old epoxy that you can't remove.

It has to be 90 degrees to your elevator and 90 degrees to your wing. Can you adjust the latter two more easily? Its all just relative.

The other option is to add balsa sheeting or sticks to the fin sides and then sand the whole lot true. Is it an ARF? Have you covered it yet?

I would just put pressure on it until you hear the joint crack. Then fill what little gap there will be with epoxy, and make sure it stays straight.

I would fly it as is,if the fin then presents a problem then I would add flying wires or tail braces to align everything.You might be surprised to know how many are flying that are off more than yours.
