Hybrid Savage Bushwacker
Right after I saw Localfiends 8th post with the Cub picture, I went searching, found the Zlin Savage Bobber.
The FT Bushwacker flies 3D almost like the Turbo Beaver from twisted hobbies.

I wanted this airplane but not out of those materials the beaver was made from or the light power system...TCBeaver and Bushwacker look very similar, but, the FTBushwacker is a much better choice.
To help build light but not with foam board, I found a way this might be done with the light dowels and a little light ply which is almost a gram per square inch. 1/8x12x48 Lite Ply 538.5grams per 576sqr.inches.
Good stuff and it's $10 / sheet on Amazon.
Here's a pic of a Savage Bobber sim to post 8, a combo in proportion of Bushwacker and Bobber where I shortened the cab height. The only paneling would be the front sides and bottom same size as FT Bushwacker planning for wing chord of 7inches also. These are the real panel dimensions.
The inside stick detail and seats are not right, yet. But I like the open frame of the Bobber. I'll just paint them red or black.
If the plane picture missing the stick detail is not shrunk by the system, then, it is the same full size as the FT Bushwacker, the tail is just a littler smaller.
I'm trying real hard to make this work less than 24oz so this plane can 3D hover with the 70gram Suppo 2217/7 1250kv "Beef" motor. This will give about 37oz thrust with a gws 9x5 dd at 11.1v
If this does not work, comes out too heavy, there is a really super motor at Altitude Hobbies for just $23, 2814/6 1400kv a 100gram motor will give 68oz thrust with an APCe 9x6 on 3s.
Wish I had bought this motor first, it would make it easy on us if our planes get a little heavy.
Finally after looking more closely at the cut down profile, I restored it to the same height as the original FT Bushwacker and it may look better, this is it with a ruler too. The tail might be made bigger and the wood panel pattern is for both 7" or 8" chord wings. The drawing came with an 8" prop but you can see there is plenty of clearance for anything.
This might 3D really good with a fattened s5020 or NACA 20 airfoil. You can use Profili to generate airfoil patterns. Now I think I'm ready to cut wood.
Now here is some fun if you have ever used Real Flight Sim and put special airfoils on a funfly plane, then you have seen the fatter foils hold you in the air real easy, you can easily fly inverted without any dihedral.
The s5020 most resembles the foil FT makes with their DTFB wings.
NACA 16 is used on the Sig Somethin Extra 48" stunt plane, and that fatter NACA 20 might really fly slow and would give lots of controlled flight, no tip stalling. Thin wings stall first.
Feel I made a mistake recommending s5020 after seeing how thin it was. Look at this Clark Y 15 produced in Profili, fatter foils resist tip stall to a much greater degree. This looks much closer to the pattern the flat bottom lifting foils, cargo planes, Cubs, FT uses.
Notice the Bushwacker foil looks like this. Skinny foils tipstall, fat ones don't. The symmetrical foil will not produce Bernouli lift but will give the 3D performance you like and this fat Clark foil might come close, it will produce great lift. You could use either one of these fat ones probably without any dihedral, a straight wing.
I was thinking after making the Savage Bushwacker fuse, of making a wing with a lifting foil just about like the Clark Y 15. Playing with Real Flight Sim and a fun fly plane changing the airfoils and other attributes on planes really tells you a lot concerning changes you make and the foils behaviour.
I was wanting 3D performance and something that would make lift and float, I live in south Tx where we have thermals but flat land.
A big fat NACA 16, if you want strictly 3D, would let you put the plane exactly where you want it, the air grips it better, won't stall, wish you could try this on a sim and see "PropSpinner" constant chord would not bother this at all it's just not like a Spitfire with the thin elipse wing shape given to the tip stall. Now you try a NACA 20, that one should be extreme and slow. See the E flite Edge 540, the foil looks like a NACA 16.
