Center section flaps As with the flaps, elevator and rudder, just grease up the hinges, open up the hinge slots and epoxy these pieces together. For the aileron servos I used the Hyperion Atlas DS 095 wing servos. I like these because they are fully programmable, thin, and lightweight and have a nice mounting scheme. There are several plywood mounts that fit these servos with a little trimming. Just be sure and glue these mounts with epoxy. I even went further and added some thickened epoxy fillets.
Also be sure and rough up the area that these will be glued to.
My build step:
1) Make sure you trial fit the torque rods. Mine were a snug fit on one side so I cleaned this up my using a round file to allow the torque rods to pivot freely.
2) When I trial fitted everything I notice that there is not enough travel to fully deploy the flaps due to the small opening for the T-connector. To fix this I slotted the opening on both sides. This allowed for more travel and I was able to get the full movement on the flaps
3) Slip the T-connector into the slot
4) Slide in the torque rods. Position the T-connector all the war towards the rear of the wing, level the torque rods then tighten the setscrews on the T-connector.
5) Trial fit the hinges in the flap and the wing center section. With a pencil mark the location of the hinges. As stated above glue hinges in a similar manner.
6) Glue the hinges on the flaps first. I opened my slots slightly with an Exacto knife so the epoxy wouldn’t get all squeezed out. Be sure and grease the pivot points on the hinge.
7) I applied a little grease to the flap leading edge where the hinges were to keep the epoxy from sticking in case the flaps moved down and made contact with the Epxoy. (See yellow marks)
Outer wing flaps and aileronsHere's my build steps:
1) Glue aileron and flap hinges similar to the above steps used for the flaps. When gluing the hinges into the wing, to make sure there was no binding between the flaps, ailerons and wing edges, I slipped several old plastic hotel cards between the pieces.
2) Next is mounting the aileron. Similar to the rudder I used thin wing servos. For the aileron servos I used Hyperion Atlas DS 095 wing servos again. Similar to the rudders I again used the provided plywood servo mounts, these mounts do require a little trimming to get the servos to fit. Again be sure and rough the surfaces to make sure there is a good mounting surface
3) Outer flap servo mounting. For the outer flaps I used the Hitec HS-7115th wing servo’s. These come with their own mounts. Unfortunately I also modified these slightly. One on the right is the unmodified while the one on the left shows what I cut off to make it fit better.
Be sure and rough the surface.
4) Once the servos are glued I marked a line perpendicular to the training edge of the wing from the servo arm to the flap and aileron.
I them made a mark where the servo horn will be mounted.
5) A small pilot hole was drilled making sure that the hole was perpendicular to the surface. This was then followed with a bigger hole and the servo horn screwed in place. The servo horns have bearings so there is no binding at all on these
One thing that I didn’t like was the bright chrome look of the servo horn and opposite side mounting washer. The plane has a nice camouflage paint scheme so these chrome pieces really stand out.
To fix this a trip to the hobby store was made and some matching paint was found. While the paint wasn’t a perfect match it was close enough that it looks good from a little distance.

Green and Gray are: Model Master Enamel paints
Brown is: Model Master Acrylic (Hobby store was out of the Tan enamel color so this was the next closet one)
