Freewing Mig-21 + Kingtech turbina

moj sedmi mlazni neka bude malo drugačiji... naš dragi Mig

Izrada spremnika za gorivo metodom printanja na 3D stroju te geliranja u epoxyu,
samo što ovaj ima rupu u sredini za ramenjaču, zašto bi bilo jednostavno

veliki izračuni za održati styro čitavim pri tim temperaturama

ista površina krila kao puno teži T-45 (5.2 vs 3.6 kg)
pogon od preko 1:1 ( 4.5 kg mlaza)

CG je 27.5cm kada je pun goriva, pri kraju tanka(30%) je 28cm, a ako se podigne nos na slijetanju onda se to malo goriva prelije u sam kraj tanka i onda je CG 29cm.

kočnice će trebati da ga se zaustavi na slijetanju jer turbina na leru gura kao EDF na 1/3 gasa koji svi spuste na 0 kada slete.

još ima posla spriejda oko ugradnje elektronike i RC opreme...

Ja nebi riskirao lose slijetanje po takvom vjetru. To si vjerojatno letio ovaj vikend.

Shema je super jer se i izbliza a pogotovo izdaleka i jos pri tim malim brzinama jako dobro vidi koja je gornja strana a koja donja.
