Hey if the elevator works as it did before the break, with that popsicle stick it'll be fine.
There's no magic trick here. You're using your ingenuity same as I do. Foam or popsicle sticks or skewers... Whatever works. No sweat.
I crashed my first plane so much and repaired it so much it was more glue and bamboo skewers than FB by the time I retired it! Darn thing still flew like a champ but it was crooked and crumply all over.
Maybe I should make a new one one of these days.
