I am presently at Jodhpur on my annual leave and have spent over a week.... about a week more to go. Purchased my Hitec Aurora 9 radio and some Balsa and the best propellers one can buy. Got my 8x6, 9x4, 9x6 and 10x6 nylon propellers.
These propellers are half the cost of generally available propellers in the market and excellent to use. Also available in Glass Filled Nylon versions for Glow Plug engines. I have used them for many many decades....... well been using these since early 1980s and I prefer these propellers over any other propellers. SHarma's being the pioneer of Aeromodelling in India have been suppliers of aeromodelling good since late 70s or even before.
Well I recommend these for all model flying. They are also available in 12x6 size.
