Charging Battery
I want to know how long is the charging time for the charger that comes with the Aero Hawk Heli. Can I buy a nice 15 minute charger with a current limiter and charge the small battery pack?
Thanks!
Thanks!

What is the Mah rating of the charger you have?
Fast charging these small Ni-mh's kills them real quick.
The charger you got with the kit is probably 300Mah??? this should charge in about 1 and half hours....

If you have extra $$$, get a good "high frequency trickle" fast charger. Ussually the charger included on the kit is a linear type charger which makes a shorter battery life.
Common trickle/pulse chargers are around 50Hz to 100Hz and a good charger is 1Khz to 2Khz range.
It's like this.
Linear charging provides a better punch but drains faster (and easily kills the battery) while pulse charging provides a longer usage of battery with somewhat lesser punch.
A high frequency compensates the punch and the "life" of a battery.
Please do note that if you intend to do fast charging, you have to provide a good dissipation of heat generated by the battery (a blower in front of the battery will do).
I'm not an expert but this is what I learned on the surface R/C. I may not answer your question but just want to share some info.
