I received my WH SU-26 a few weeks ago just after Tom got the last shipment in, and I am very pleased with the quality and workmanship. The price is right and I think the factory did a good job on mine overall.

I'm taking a little extra time assembling as I also compete in RC Combat and more recently Pylon Racing and had a couple contests to get ready for.

Here are two issues I found that others may benefit from sharing;

1.Landing gear attatchment- As others have noted the gear don't seem to fit quite right and I noticed one person re-drilled mounting holes and was very upset. I had the same problem but took a different approach. The problem on mine is the way the plywood fuse sides extend slightly below the plywood bolt plate on either side. That's right where the bend of the gear before it exits the fuse side is. When mounting holes in plywood are aligned with tapped holes in gear, the radius of the bend in gear is jacked up on that lip of ply that sticks below ply mount plate.

If you continue to insert the gear about 1/4" further into the fuse it clears the lip of ply and settles up against the mount plate. Unfortunately by then, the tapped holes in gear are nowhere to be seen from above having moved completely off the holes in ply plate.

A.)Of course one obvious fix would be to run a long drill bit down thru the fuse and the holes in ply plate to drill and tap new mounting spots in the gear. (Cursing optional)

B.)One other possible fix would be to dremel or cut away that little lip of ply where it interferes with proper gear seating, but that looked like it would require an enlargement of the slot the gear go into to work through, and repair afterward. (More cursing optional)

C.) So I settled for this fix which worked for me; using material of a thickness that matched the lip of ply that causes the problem (aprox 1/8") , I used 1/8" HDPE plastic and cut a spacer plate for each gear and marked and drilled bolt clearance holes through it and tacked it to the gear with 3M77 adhesive spray after test fitting to insure clearance and alignment.

This required enlarging the slot in the fuse the gears goes into slightly, which looks fine considering, and the plane will sit 1/8" taller. It seemed the least invasive fix, and if anyone wants pics, I'll dismount one side to show you what I did. It's pretty simple.

2.Elevator servo location in the new 87" batch that I received seems much lower than the pics of other planes in this build which show the servo high enough to have it's arm pointing down. You'll see from my pic the low location of servo cutout required me to put arm on pointing up. I was worried this would be a problem at first. The geometry seemed wrong. When the control horn on the elevator travels forward and pivots up (during down elevator command), the arm on the servo is going forward and pivoting down, a conflict when extreme throw is used.

I figured before I started whining and complaining I'd at least get it rigged up and try it out. Even though the geometry seems wrong and I think would be better if both servo arm and elevator horn were pointing in and pivoting in the same direction, this setup still looks like it allows for lots of throw before it hits the point of going beyond proper extension into binding. I should have taken pic of full up and down throw for you to see what I mean. Let me know if anyone needs to see that, be happy to oblidge.

The other tip to pass along and my question; I had previously noticed comments about the two Horizontal stab locations, and having chosen the rear position made what I think to be an erroneous assumption that the rear tail servo position is for the rear stab location. After cutting it out and seeing how close that is to the elevator I chose to open the front servo location which appeard both higher and just far enough in front of elevator to allow a better linkage moment. It seemed like the up servo arm down control horn situation would be even worse when coupled much shorter so I installed mine in the front spot.

Is the rear servo location for dual rudder servos? If you put elevator servos there it looked like they would be in the way of pull-pull rudder cables. So choose wisely before cutting the covering away or you'll be patching it like me! Ultracoat "True Red" seems to be a near perfect match.

Tom, you might want to put the SU-26 instruction addendum in your download section along with the general assembly download. Mine actually came with no printed instructions and I had to get the Sukhoi addendum from someone on these build threads. Thanks.
