I have built some airplanes. But I m not able to build or make one perfect landing gear for those. I need to hand launch them. And so landing becomes a very hard task without landing gear. I m Indian. In india landing gear are very costly not talking about retractable a normal landing gear. That itself costs a price of a ready made plane. It's very cheap on flute test website. But Indians selling for a very high price tag. So trying to find a way around for this problem. Thank you... Please help me.
