thanks for the info. Guess i need to do some research on charging these with a non eflite charger. I am pretty sure my charger will want separate balance and power.

edit: Ha OK got my head out of the sand. I see in the picture he just took the ground and last voltage lead (the 7.2v one) and made a discharge cable out of it. easy enough!

I don't think anyone will already have suitable batteries as this heli is a new size. Almost everyone will want at least a one extra battery, if not several. It was a really nice touch selling the mCP-X with two batteries.

No need to mod the battery. That wiring is in the ProgressiveRC parallel charging cable. I use this with my TP610 and Turnigy 2x200w chargers. Works great. One lead on the battery is all you need for the 2S UMX's.

Does anyone know if they use the centre-tap wire (3.7V) to, say, power the receiver or the full 5-in-1 board or is it just used for balancing?

If they do, you will need to sort the balance and power leads carefully if changing connectors.

That would be a first in their UM line of 2S boards. I run lots of batteries with no center tap in the power plug in Sbachs, Strykers and Beasts. I also doubt they'd set a power scheme up that would unbalance a pack. But I don't know for sure.

Looks like it is necessary to take off the canopy to replace battery. Very annoying for me.

I was thinking the same thing last night,, But realized no more problem finding just the right size battery to slide into the battery tray.. So I'll make the trade off for this one. Just makes it more like the big boys now...

Also harder easier to adjust cg for said batteries. And going along with what Bob said, it cleans up the undercarriage and makes the thing look more like a helicopter and less like a toy.

Actually it makes it harder to get the right CG if you like to use larger batteries as it's forward now and not under the mast.. But I think it will handle the range of batteries I have in mind.. And lots of room between the gear legs to hang some big ones if needed...
