Hi
Please give me some advise
I have a bit of a dilemma I have a 90 size pattern plane with a one piece elevator using a joiner which I stuffed up when gluing in as the two halves are 1.5mm ( 60thou”) out of being square.
Now for the questions
1. Do I just mix out the non tracking (how ?) with Futaba 10 g
2.Do I cut the joiner and fit a extra servo to the tail ?
3. Do I add trim tabs to the elevator trailing edges to even them up ?
4. Something else I have not mentioned ?

Thanking you for your advise in advance.

Cut the joiner and add a servo is the only way for the airplane to be "true" at all speeds.

Is the joiner metal or wood?

Get your heat gun and heat up the areas where the joiner attaches to the ele. Halves. Then use equal force on each ele but in opposite directions. Be sure you apply the pressure to the entire ele and not just one spot on the ele. Continue heating the glue area with the force applied and when they look to be level with each other let it cool and use books or something to continue holding the halve equal to one another.

This method works for small corrections and seems to work well. I have done this several times and had good results each time. I would try this first because you don't have to add weight to the plane, you don't have to butcher up your joiner, and is easy to do.

The joiner is composite of some sort it is a pale yellow colour sandwich material joiner.
I will try heating and see if that works first as suggested

Thanking you

+1. Heat and twist, let cool, repeat if it's not sraight.
