Help! Piper L-4 Grasshoper Master Series

[otto54]

Hello, I am in the process of designing a Piper L-4, I have taken a papermodel as a reference since it is quite simple to change the design and adapt it to foamboard
I hope you can help me finish the project or even help you in the design of your airplanes.

you dont show the parts thats needed, skins, internal rear, eg. Thats what interesting, and just need adjustment at formers approx. How to "pick" together paper parts aint so interesting, as that plans here are.

Of course these are, they could be simplified

there you got it... Remove anything that dont have with internal structure, and fuselage/wing skins to do.. You can forget rolled paper as wingbraces, landing gear , wheels as here,eg. I would forgot interior too, and rather used that space for battery/electronics.

im not into such plane at moment, my planned builds on next 3 planes are already set, but yes, ive used paper model plans before to make a foamboard RC flyer. Mainly the skin "sections" with formers (formers resized to use 5mm foamboard around). Internals i used build batterybox, (perhaps FT powerpod in some), and "spar" all way to rear rudder.

go to this thread : https://forum.flitetest.com/index.p...ying-a-new-source-of-inspiration.65659/page-2
down at site, there you see one have put out papermodel plans for a Ki-44.... and see what i comment, then you know whats point of interest to keep.

i dont see the reason why should make a angled froward part on that rear spars. Easier to make fromer placement if not, + if your main tailfin is into the spar as one part, it will be easier to get it stiffer, If not, close to need fillets to hold it best possible vertical. (can glue it to a spar thoug) If your building big, such that the tailfin is gonna get a few layers, then it needs glued to a stabile part.
