How do you align two wing halves of an arf airplane?

Did you check the balance?

Hi Vic,

So did you get your plane back after it disappeared into the clouds? Or did you have to buy another?

I love the World Models MachII. I've had two of them, one is still alive! They are cheap and they flight great.

Anyway, below is an image from the manual of my SU-31 ARF manual. It shows you how to measure the distance from the trailing edge to the tail feathers when aligning the wing.

Is this the info your looking for?

Unless you are WAY off, there is no reason why you can't trim your plane to fly correctly. It may not fly true (perfectly straight), if the distances are off a little bit... But you still should be able to fly them.

It sounds like your plane could have been tail heavy if it continued to climb out of control. Be sure to balance your RC plane as this is very important!

Assembling World Models MachII
by: Vic

I was assembling world models machII low wing arf plane and i did what you have said but after gluing the two wing halves then I test fly the plane it swerve to the left and i corrected it with right aileron it was ok.

But the plane continue to goes up very fast and the plane got lost in the clouds.

Matt how do I align the leading edge and the trailing edge? Do i have to measure the right and left leading and trailing edges height?

Maybe you could shed son\me light to my problems.

Thanks vic

Wing Joiner
by: Wing Jointer

Hi Victor,

There is a wing joiner that sets the dihedral and helps lock the two wings halves together.

This wing joiner helps to keep the wing aligned. You also have to make sure the ends of the wing are aligned properly, face to face, with no gap.

Keeping the wing supported while the epoxy glue cures is probably the most tricky part of joining the wing together. Some times you have to get creative in how you support the wing in a manner that will keep the alignment true while the clue dries.

Does this answer your question?

Do you have a specific ARF you are assembling?
