Volitation double horse advice

[purplenut]

Hi
I have bought one of these helis for my Son for his birthday just to start off with.
It all works but it seemed not to have enough power to take off, so i ordered a new Lipo and tested this last night, but still not enough power.
All it does is go round in circles.
I would really appreciate some advice on this as i keep letting him down:thumbdown:
Thanks
Leon

One of the main motors is weak. It's a common problem.
I'm assuming it's an older 9053 with brushed motors, rather than the (much) more expensive brushless one?

Yes looks like the one, i will buy the motors and see if that works.
Thanks for the advice and link.
