Tiger 120 weight issues
I need some suggestions on removing some of the wieght from the tail of my Tiger 120.
I built it light (or I tried to build it light) and added nothing at all to increase the tail weight, but I need over a pound of nose weight to reach the CG, and it still flys slightly tail heavy.
Here is what I did in the build:
1. I used a Sullivan tail wheel gear (lighter than the rig that Goldberg had in the ARF) and a smaller, light-weight tail wheel.
2. I used only one elevator servo and used light-weight Sullivan Carbon Composite control rods for the elevator.
3. I used vinyl coated kevlar pull-pull cables for the rudder instead of the metal cable provided.
4. I used light-weight carbon gear for both the rudder and elevator horns.
5. I am running an OS 1.20AX engine with an APC 15-10 pattern prop.
I used the original hardware for the vertical stab supports, but I have a plan to remove that metal and replace it with the vinyl coated kevlar and vinyl tubes with nylon attachment 'hardware' (remove the metal eye bolts and replace them with vinyl tubes through the vert stab, horizontal stab and attach underneath with the nylon 'hardware').
Other than that, I don't really have any more ideas on how to remove some of that weight other than removing covering and chopping wood from the horizontal and vertical stabs, but I really don't like that idea, but may have to if it comes down to that.
Ideas would be greatly appreciated.
DS.
