Question on horizonal stab balancing
Quick question guys
Working on my F-15,,,, I shut down the power and one of the stabs drops down. Thus the trailing edge is heavier.
Is this a consern??
I am running a 154 oz servos on the elevators.
I took the stab out and thought of static balancing it and it would take better than 2 oz's of weight to make it level.
Again.... is this a consern??
Thanks guys

Thanks guys........
I think I will just leave it the way it is.
2 OZ's in the leading edge of the stabilizer is a lot.
I really hate to cut a hole in the inside of the stabilizer to install lead weights.
Thanks again

RE: Question on horizonal stab balancing
Hi,
It's just as important to know which F-15 it is. If it's properly designed, the stab should be tail heavy. When properly designed, the only benefit to static balance less wear on linkage. It's an oft-debated issue...

RE: Question on horizonal stab balancing
Although I don’t have years of experience in flying jets I must admit I cant see the logic in not balancing the stabs.
I see a servo would have to work a lot harder to keep the stab in the centre position if the stab is not balanced.
I believe that with larger stabs especially they should be balanced. I have also noticed that sometimes servos struggle to keep stab at centre if stab not balanced and will flutter a little on the ground, which this would also flutter a little in the air. Although during flight I could not seeor notice the aircraft fluttering I believe that there would be unnecessary strain on the servo.
This is just my belief from what I have seen and think and im open in hearing other peoples opinions.
In saying this I have balanced the stabs on my MIg-29. For those watching theput together tread (build tread) I will update in the next few weeks
