HOW MUCH LONGER WILL THE LiPo last over the Ni-MH under non-agressive flight ??

I bot a Walkera 22D - came with a Ni-MH 650mAh 9.6V 8cell battery and related charger (OUTPUT: DC 15V 300mA)
The manual says Ni-MH will last 3-6 min depending on the type of flight.

Thanks in advance.

p.s. I can give you a link to my heli package if that helps.

If you don't change any set-up it would last over twice as long. You may find having to use more throttle though to get same speed. If the speeds were matched, then it would be less than twice as long.

yeah, basically up to 200%. Here is an example though. On my blade cpp I get 11 min and 30 sec out of an 800mAh pack and 15 min even out of a 1250mAh pack, when I should theoretically be getting really close to 18 min of flight time because it has an average draw of 4 amps on the 800mAh pack. The main thing though is the bigger battery weighs 35g more than the smaller battery, so it takes pretty close to 5 amps (if I remember right, 4.8A), so it doesn't last as long and the motor gets alot warmer.

I dunno what your NiMh pack weighs compared to the lipo compared to the AUW of your heli, but you're probably looking at 70% or so additional flight time.

The other thing to consider though is you are dropping from almost a 3s lipo voltage range to a 2s lipo that starts at 8.4v instead of the approx 10.4v on the NiMH. You might consider throwing an extra heatsink or two on each motor and going up to a 3s lipo.
