Which motor do you have in your plane Chetanv23? NiMh are only used in brushed motor applications mainly because they can't supply the power required by unbrushed motors. I've never heard of C ratings for NimH batteries. I doubt they'd be able to supply 10c.
The market is flooded with very poor quality NiMh from China. I'm not sure of India's market but here in Australia there are people selling cheap and nasty copies of name brand batteries. If you do buy them, try to deal with a reputable seller and stick to names you know such as Panasonic or Sony etc. They cost more but believe me there's nothing worse than trying to get some of those Chinese batteries to work.
I was given two planes which had Nicads for power. I removed them and swapped the motor and ESC. The planes more than doubled the time they'd stay in the air.
