Prettiest hangar queens I have ever seen.
Like most RC flyers I have a hanger full of aircraft ready to fly, all classic and pattern ships. The Kwik Fli III has been flown many flights and the Tiporare is in the queue to get flown soon.

We were on the road all last week so I was unable to work on the Cold Duck until today. Last week I glued 1/8” X 1/16” bass wood strips on the trailing edge of the 1 ½” wide aileron stock from a Howard Engineering Kwik Fli III kit. The aileron stock was carefully aligned for centering and temporally rubber glued to the trailing edge of the wing and rough shaped with a razor plane. Today, I finished shaping the ailerons using 1 ½ ' long board with 50 grit sandpaper glued to it and another smaller block with 150 grit and followed up with 220 grit.
The next step will be cutting the root and tip pieces off each aileron and then shaping the leading edge of the aileron. On the original Cold Duck the ailerons extended to the tip of the wing but on this build the ailerons will stop about 1” from the 1” wide wing tip block.

I cut the ailerons to length and glued the 1” wide rough cut wing tip blocks on. The ailerons stop 1” short of the tip block. A 1” piece of the aileron tip is glued to the tip bock and the trailing edge of the wing. The leading edge of the ailerons are not shaped yet.

The RJL K.61 power plants arrived! I’ve often thought about the buying some K.61s after MECOA started manufacturing them and I wasn’t disapointed. The workmenship and fit and finish is excelent. The cankcase mounting area is 39 mm wide like the majority of the clasic 61s (Veco and K&B 61, Webra Blackhead, HP) but the engine is longer at 98 mm. The K.61 hoursepower is advertized at 1.8 and the engine only whighs 17.5 oz. That makes the RJL more than two ounces lighter than my silver case Irvine 61s.

The wing roots were sanded to set the wing dihedral. The original had 1” under each wing tip. I reduced the dihedral to about 5/8” under each tip so the top of the wing surface has a very slight dihedral angle of about 1/16” at each tip. The wing roots were coated with 30 minute epoxy and the wing taped tightly together with masking tape.
