Kuchepetsa thupi ndi chinthu chofunikira kwambiri pakupanga ndi kupanga ndege, komwe kungapangitse ndege zankhondo kukhala zolimba kwambiri pakuwuluka ndikuwongolera kuchuluka kwamafuta mu ndege zapagulu. Koma ngati makulidwe a zigawo zooneka ngati mbale pa ndegeyo ndi yoonda kwambiri, idzakumana ndi mavuto osakwanira mphamvu ndi kuuma. Poyerekeza ndi kuwonjezera mafelemu othandizira, kuwonjezera zinthu zopepuka komanso zolimba za masangweji pakati pa zigawo ziwiri za mapanelo zimatha kupititsa patsogolo mphamvu yonyamula katundu popanda kuwonjezera kulemera.

Chosanjikiza cha matabwa opepuka kapena thovu pachimake cha pulasitiki chimadzazidwa pakati pa khungu ndi mkati ndi kunja kwa khungu lopangidwa ndi utomoni wagalasi wopangidwa ndi epoxy resin (pulasitiki yolimbitsa magalasi). Mitengo yopepuka inalinso imodzi mwazinthu zakale kwambiri zamasangweji zomwe zimagwiritsidwa ntchito mundege, monga ndege zodziwika bwino zamatabwa pankhondo yachiwiri yapadziko lonse - Bomba la British Mosquito Bomber, lomwe linapangidwa ndi plywood yokhala ndi zigawo ziwiri zamitengo ya birch pakati pa matabwa opepuka.

M'makampani amakono oyendetsa ndege, zida zoyambira zomwe zimagwiritsidwa ntchito zimaphatikizapo kapangidwe ka zisa ndi mapulasitiki a thovu. Chisa chooneka ngati chofooka chimatha kupirira kuphwanyidwa kwa magalimoto olemera chifukwa chisa chokhazikika ngati gululi chimalepheretsa kupindika, zomwe ndi zofanana ndi mfundo yakuti makatoni a malata amakhala ndi mphamvu zopondereza.

Aluminiyamu ndiye chitsulo chomwe chimagwiritsidwa ntchito kwambiri mundege, kotero ndikwachilengedwe kugwiritsa ntchito kapangidwe kamene kamakhala ndi mapanelo a aluminiyamu aloyi ndi masangweji a aluminiyamu zisa.
