Aileron Assembly

The Aileron assembly is pretty easy to put together, so I will highlight some tips during my assembly and suggestions provided by other builders.

Evan Brunye has a very detailed and helpful video on the assemble of the part

2.4 Sling TSi Wing - Aileron 

 Here is another highly detailed blog on the assembly of the right aileron

Sara's Sling Build log

Parts were cleaned and prepped using my established procedures for cleaning and treating components prior to assembly.

 I like the symmetry of laying out all of the left hand and right hand side components before and after cleaning and prep.

 


 Parts are well labeled and make it easy to complete hardware inventory prior to assembly.

TIP

  • Each part has a part number, that is until the plastic has been removed and due to their similarity it becomes difficult to re-identify later.
  • I started writing the build document reference number instead of the full part number as the P/N are typically not referenced after the cover sheet. You can use pencil or Sharpie to label the parts for identification purposes.

This is most useful when there is a delay between prep and final assembly as was in my case.

 
 
Parts fully prepped and rib #5 & #7 have their bolt plate doubler and AN4 anchor nut plat installed.


TIPS

  • Make sure you complete the dimple process BEFORE you rivet the aileron hinge brackets because you will not have enough room for the dimple die and you will have to remove multiple rivets.
  • I believe some builders with extra dimple die sets ground some of them down so they would fit in tight spaces.
NOTES
Save yourself some pain and suffering and dimple before hand, trust me. 😉

I had a bit of trouble dimpling the skins because at the time I didn't have the extended neck for my rivet squeezer.
 
*I opted not to purchase a large dimple press because the quick build kit requires minimal dimpling.
 
I did purchase a few sets of these for tight spaces and they work reasonably well but not recommend for dimpling the entire skin.

Ideally go with the tools below, they worked much better though a bit harder to used on the sheet metal and will be useful throughout the build.



 
TIP
  • As suggest leave the end-cap rib #1 off until you have inserted the counter-balance.

  • When you are ready to pull the rivets for the those near the hinge brackets, you will find that the riveter won't fit. I used a specialty tool from ATS that has been invaluable for close quarters locations.

Completion notes

I completed most of the riveting omitting the leading edge rivets until I completed alignment on the wing.

I was missing the left and right aileron balance tubes, as these were back ordered.

Propeller Installation

It was finally time to install the propeller on the engine, this has been a long time coming.       The blades are unpacked one a time and i...
