How do you make rc helicopters?? I have made rc aircrafts and want to try making rc helicopters....

Hope you are asking for Helis and not Quads.

Building Helis are quite different from Fixed wings. And much more complex (completely my opinion)

You can start reading threads from http://www.rcindia.org/helis/

RCBazaar sells a kit called Hiller Hove you can follow the series of videos in you tube https://www.youtube.com/watch?v=qJVO95Lswdw&list=PLB74AA54D70E1125A&ab_channel=RcBazaar

Though I found the kit is not good at all (again completely my opinion) but building techniques are almost same for all type of kits apart from Flybar or Flybar less systems diffrences.

One word of caution....spares for helis are very hard to find in India these days.

Thanks and yeah I am specifically asking for hellis and not quads 😅
