Well, after seeing how well this Cox .049 r/c engine works, I then start planning a model airplane for it.

Hola Mauricio!!!….. Your finely tuned .049 will be a great match for the Citabria….The plan appears to be an enlarged version that was originally free flight and you will add your own structure method?….Looking forward to another of your finely crafted builds…Very Happy

Thanks guys for joining me!
well, I was thinking about ribs or Styrofoam for the wing, yes, no...finally I'm going to build a foam wing, the ribs are ruled out, the reason is that I will have a very firm and even wing, in turn for previous experiences, I can make it very light, so I go that way.
In the first photo you can see the profile of what could have been the type of ribs, but in the photo that I leave here, you can see the pair of profile sheets that I will use to cut the foam.
I'm excited about this project friends!

Looks like a good plan Mauricio!…. I have tried to make foam wings in the past with a hot wire cutter but with less than best results…. I look forward to seeing your procedure Popcorn

Dear Roberto, I will do a step by step of foam cutting then...you will see.
In the meantime, I just received a Cox .09 and a Cox .010 from a friend, I'll take a break with the Citabria and tell the story of the engines here:

So, modify the Wen-Mac .049 motor and it is ready to use.
The Wen-Mac .049 and the Cox .049 will share this aircraft model, it is also possible that some more engines will be used on this aircraft.
The idea is to do it without a fairing, so that you can fit engines without major modifications.
I began to cut the wings out of foam, since the profile is biconvex, which means doing some acrobatics too!....
