Give your RV-12 the finishing touch with a Tip Kit. Cover the unfinished ends and give your plane the look it deserves.

Default Aerodynamic benefit?

Today I worked on the stabilator tips which I purchased from Clint.
I am quite impressed how nicely the tips fit to the contour of the stabilator ends.
However, on the bottom side near the trailing edge some additional work will be required for a perfect fit. Sanding will not be sufficient, it's more that the tips needs to be squeezed a bit together in the last 2 inches towards the trailing edge.

I also haven't drilled the mounting holes yet into the stabilator ribs, so I still have the option wether to finally install the tips or not. The additional weight including J-nuts and fasteners is 2lb and 3oz which is not quite zero and it is a long arm from CG.

What I am wondering is the aerodynamic effect to them, if there is one at all.
So I am looking forward for some opinions of you, the aerodynamic experts out there. Dou you think the tips are for any good in terms of aerodynamic efficiency.

Thanks a lot.

No aerodynamic expert here. I think they look great, doubt whether they will add any speed, and had the same fit issue you found. I eventually decided not to install them because I wasn't comfortable with the not-insignificant extra weight on the all-flying stab. However, there are lots of people happily flying with them, so maybe I was worried about nothing. Wouldn't be the first time, and they do look nice.

If I calculated correctly, 2.2 pounds added to the stabilator will have the same
affect on aircraft balance as 4.6 pounds in the baggage compartment.
That affect can be mitigated by eating a few more $100 hamburgers.

Good thinking Joe, but then I might be forced to reduce my fuel load to compensate for the total load increase, and not be able to get home from the last hamburger stop.

How accurate are your scales for the empty weight calculation? Look at the error margin in the original CG calculation and see if this is noise level.
