When I did mine, I used the inner ailerons as flaps, and built barn door ailerons.

I used a Super Cub cowl made for the Sig 1/6 scale kit, by Fiberglass Specialties.

I'm trying to decide how long the flaps should be...so far all I've been able to come up with is using the Eflite 25e Cub as an example. It's flaps are 60% of the total available control surface area. (ailerons 15 5/8'", flaps 10 3/8")

On my CG Cub the total available control surface area is 28 1/2"...so using 60% gives me -

Ailerons: 17"
Flaps: 11 1/2"

Anyone with any suggestions? Comments?
For my build on this Build Log I made my flaps 9" long and the Ailerons about 19-1/4" long, but I have not yet made my maiden flight. As soon as I make my first few flights I will post a response of my findings. Also, I found that I was not happy with the CG cowl and I might check into the 1/6 scale super cub cowl.

That would be fantastic! I have not cut mine yet so I can still make changes. I'm looking for STOL type take offs and landings....

I ordered a Super Cub cowl from FS last week - I can post a photo of it when it arrives if anyone is interested.

Just received the cowl in the mail...here are some photos. It looks very nice but I'll have to figure a way to blend the sides into the fuse on the sides - the top and bottom fit well. It was $25.00 plus $16.00 shipping.

No need to blend, that looks about right. Check some pics of super cubs...there is a bit of a space between the fuse and the cowl on the real thing.

So, how are you going to join those two different shapes?

Ah. A vent bulge which must accommodate the larger engine.

Nice photo - thanks. After viewing it I guess I'll make a small filler block to support the cowl where it's the widest and leave the rest open for cooling.

Anyone have an idea for creating the round gizmo on the front bottom of the cowl?

I'm going to mimic the four fasteners on the bottom side with small drops of carpenters glue.

Round protrusion on cowl

Go to a craft store like Micheals and they should sell small diameter wooden balls. Just buy the appropriate size and then cut and sand to size, then simple glue into place.

Maiden Flight

Well I made my first maiden flight today on the completed Cub. The first few seconds of the flight were quite stressful, wow! The plane required trimming on all three control surfaces. The initial take off revealed a plane that was rolling left, diving and turning left, plus it was the first use of my new Futaba 14SG radio. But after I calmed down and trimmed out the plane, the rest of the flight was quite good. I flew for 6 minutes on 5S 4400 Sky Lipo battery and upon landing the lowest cell was at 3.93 volts. I was only able to get in one flight, but I learned a lot about the plane. The low rates I adjusted per the Goldberg recommendations and made an educated guess at the high rates. The high rates will need to be increased and I also need to mix in some down elevator with the flaps. Once I get the plane fine tuned I will post my finial settings here. By the way, this plane really is quite the floater and the E-Flite Super Cub 25e landing gear that I installed worked flawless (highly recommend).
