Thinking of buying one for my MT2, but they come without chargers.
What charger do u think they use for the above?
Can show me a picture of the charger? And where to get?
Budget below $30
Wall charger preferred. :D

The hump pack will be 6V. Any 6V AC to DC adapter will do. Just make sure it's ard 100mA current so you dun overcharge your batt. Charging will take 10 to 12hrs. If you get higher current ones, you'll have to watch the timing carefully.

Since your rotor start uses a 6-cell pack, which translate to 7.2V, yes, you can use the charger. How many amps is your charger output?

Er....I was looking for the output amp. :rolleyes:
Anyway, since it's originally used to charge the 6-pack, should have decent amp. Yah, can charge the rotor starter batt pack. If there's no auto cutoff, you've gotta watch the time.

The hump back pack is a 5-cells and that translate to 5 X 1.2V = 6.0V.

As I recall, you quote err.. there is a compartment to charge 8 'AA' batteries and a female connector for the 7.2v 6 cell batt.
So where you get the 6.0V for the hump Rx battery from? :rifle Use the 7.2V output to charge your 6.0V? :rolleyes:

Actually can still use your 6-cell charger to charge your 5-cell batt, but got to do it manually. Connect a voltmeter across the battery and when your cell reach around 7.5-8.0V, switch off your charger. If you do not have a voltmeter, switch it off when it is hot say around 40 degC. But of-course the charging quality is not as good as a delta-peak charger.

Get a cheap delta peak charger like Hitec CG-340 and power it up with your PC. Rotor selling for S$70 or less.
