I picked up a couple of GP Cubs (20 size) from a club member that both have Futaba MCR-4A receivers with speed control built in running speed 500 motors. I would like to teach my kids on these electric.

I ground ran the one ready to fly with a supplied 8 cell nicad 1700 mah pack and the supplied 9x6 prop that dumped the battery real quick. I cycled the battery a few times and I'm only getting 1300 mah. I used the same battery with a 8x5 prop and seems to run longer without dumping prematurely.

I would like to buy new batteries and wanted insight on what I should get.

The Futaba online instructions indicate a 7 cell max pack.

Can I run LiPo's?
Can I run a 3 Cell LiPo?
How big (1800, 2200 mah) should I run?

If I stick with NiCad, or NiMh, what do you suggest?

Any suggestions on prop size?

I may try to fly with the old 8 cell pack and the 8x5 tomorrow, I have some 6 cell packs (from RC cars) that I tried that dump very quickly so wont be using them.

Your quick help would be greatly appreciated.

Thanks
Eric

We'll with no responses and nothing in history on this RX certifying it's good for more than 7 cells especially the 11+ volts of a 3 cell LiPo, I chose a 2 cell 2200 maH LiPo so that I'm safe at 7.4 volts and lighter than a NiMh.

Was too windy to test fly yesterday and was too busy today.

Maybe I'll wait to test fly when the new LiPos come - will keep you updated.
