required battery
3 cell Lipo battery
11.1v
max capacity- 1300-2000 mah
weight-120g

but i used 1250mah...slightly lower than required..
hope this will work fine in future

You did not say what prop you used.
See this. From emaxmodel.com

A few suggestions from an old timer, if you don't mind:
- Avoid sms language (it is against forum rules)
- try to give all info in one post, not piecemeal. Don't expect your readers to hunt up and down.

thanks for your advice sir, i'll keep that in mind. I'm a beginner and learning from you all
the propellor is 9" or 10" theoretically...the thing is i don't know how to measure it

Just measure from tip to tip (dia)
Look closely at the hub and on the front of the blade near the hub. Usually something will be printed/embossed there. Like 9060, 1047 etc.
