RC India

I am glad that we have people even in India who love RC I started to think its way out of my reach i am a student and though it a may seem a bit high coming from a beginner i actually prefer design my own models rather than buying but being a student i dont have enough freedom and cant accumulate enough cash  :banghead: so i rather downloaded Motocalc and RC CAD to design new planes but I didnt got full vesion so i wanna ask if there r any similar softwares whose full version i can download for free? and can anyone give me idea to make a rc aircraft using unused stuffs



THANK YOU
