Hey.
I hope you can help me!
I just bought the new little PNP 2,4GHz Walkera 4#3B V2 Brushless Heli with standard lipo 3,7V 400mah batteries.
It's a totaly new model with brushless motor just arrived from HongKong (EHIROBO.com)
After take-off with fully charged batteries the power is only about 50% and after only 10sec. it's only about 30% or so.
It can fly only about 5-10cm. of the ground.
I'm not an expert in electrics, but the chargingprocedure is pretty simple with a green light when it's fully charged.
I've tried with two different batteries but the result is the same. NO POWER.[:@]
On Youtube it seems to have lots of power.
Please help me I need some advise.
