Actually 182 flaps ARE fowler flaps. Having lots of hours in the real Skylane, I can tell you that they are indeed fowler. The flaps extend back then down, not simply hinged 90 degrees like conventional flaps.

Back on this fowler subject ?
speed20,
You are correct that the flaps do move a bit backward as they deploy.
It is due to the method they are hinged and thus are slotted flaps.
You have your choice of words and others have theirs.
Ask yourself if the wing surface areas is increased when the 182 flaps are deployed.
You may find the proper answer.
Beyond about 40 degrees the flaps become more air brakes than the normal use of flaps.

Again I fully agree with TomCrump.
Beside the definition of Fowler Flaps which involves an increase in wing area as well as a rotation to increase the downward deflection of the air flow. we should consider the definition of "unwanted intrusion".
For some people an unwanted intrusion is any posting that is not in full agreement with their own understanding or selection of words to refer to a specific condition.
In aviation circles there is a definite difference between 'slotted flaps' and 'fowler flaps'.
Incidentally 'fowler flaps' are nearly always also slotted but reference to 'slotted flaps' are not 'fowler flaps' as referred to by professionnals in the aviation fields.
The nomenclature in our hobby is not an important matter.
The appearance, the scale look for some hobbyists, and the flight performance that results is what really counts.

I hope to finish sheeting the fuse this week then time to finish the top of the wings. Before i get there i could use some input.
I would really like to make the ailerons controlled by an RDS system. I was going to get all components from http://www.irfmachineworks.com/g2rds/
Can anyone comment on if this a good idea or bad idea? Also what would you think the servo requirements would be? I think the RDS would look great since the rest of the linkages are already hidden.

The aileron drag equalization setup, if any, would also be most interesting.
I am following this thread with great attention.

I have been e-mailing back and for with Walt from I.R.F Machine Works. He answered a few questions for me
1.) Its not necessary to have the pocket centered laterally in the Aileron. I explained that the plans servo hatches (and where they are currently built) are on the inside portion of the aileron. I was worried that having the pocket at that location would not be good.
2.) I didn't know what servo to choose. He said that the same torque or less is needed for the RDS system compared to traditional linkages.
3.) He recommended the 30 degree bend HD wipers. He said they could be installed either perpendicular to the aileron or at a 30 degree angle. I know I can do a perpendicular installation but need to check if cutting through ribs would be needed for a 30 degree install.
He was very quick in his replies and I will be ordering the components shortly

I got a chance to work on my TF 182 for the first time in 6 months this weekend. I extended the turtleback over the instrument panel I had cut too short even after measuring 3 times. And I finally shaped the leading edge of my flaps so I can move ahead on the wing center section modifications.

I would say something tacky about your picture comment if I wasn't guilty of doing the same to you! So... If you look closely in the first picture you can see where I filled the seam and in the second picture you can see the shape I sanded and planed down for the leading edge of the flap. It took me a minute to realize the drill guide made a great pattern to get the shap right. I plan on forming fiberglass around the flap leading edge to make a liner for the wing where the flap mounts. Much like a certain forum does with carbon fiber.

Thanks! It was surprising easy. I also carved the Hoerner wing tips shown on the plan they were easier than I expected too. They look so much better than regular wingtips. I think a lot of shaping balsa is just a matter of picking the right density of wood and jumping in with both feet and not over thinking it or worrying about the outcome. A lot of guys psych themselves out on carving. I will admit I did cut an extra set of wingtip blanks in case I screwed them up.

Next up for me, hopefully this weekend, is finishing the center wing section modification followed by some blending on the fin in front of the vertical stab and installing the wing bolts.

I am going to start filling and sanding the fuse this weekend. I could use some input on how to blend the sheeting with the tail cone and cowl. I have a fiberglass cowl and tail cone and i am going to glass the plane as well.
There is a small area were i will need to build up the cowl because sanding the sheeting down to the cowl would be way to much. Any suggestions on how to do this?

I decided to try Bondo which worked out well. I was able to blend the cowl to the fuse with very little material. I am going to do the same with the tail cone then post some pictures

You got more done then I did I ended up ding honey dos and babysitting. Still my grandson is a blast! He loves it when grandpa gets on the floor to play with him. I'm hoping to get him interested in RC when he gets a little older. He's only 15 months right now.

Question on this build. I like tail draggers much better than trikes. I like how they can land on runways that are not in the best of conditions by just using some large tundra style tires. I also think it looks much more stylish. Besides real men fly tail draggers! ;-) I know they make a full scale conversion so is it feasible to think it could be done on the model? Is there a formula to determine the location of the front gear or would copying from the full scale conversion sufficient? If so, it looks to be lined up with the leading edge with about half the wheel past the leading edge of the wing. Also, would you build it so you can switch back to trike gear? I dont think the weight would be much more. At least not enough to make a difference flying. I also was looking for a gas engine that will power this bird nicely as well as fit under the cowl with minimal to no cutting? Id like it to have more power than needed but not so much that the weight of the motor starts to give it bad tendencys.

My 182 project is still on hold but I did pop for the Fiberglass Specialties fiberglass cowling and tailcone as my own Christmas present. The plastic cowl and cone in the kit didn't cut it. I'm planning my winter build to finish the 182 after I complete my DR.1.
