hi J,

yeah, those are the Silverlit X-Twins, the original version of what AirHogs now calls the AeroAce (silverlit was the original manufacturer of them, the SpinMasters bought the right to sell them under the Airhogs AeroAce name). i bought the X-Twin Biplane and MonoWing versions on ebay before AirHogs was selling them in the US (except for a few states). they're virtually identicle planes, just differant paint jobs. i dont know if Silverlit is updating the RXs and TXs like Airhogs is, they havent had the x-twins on their site for a long long time.

schuh007,
do you mean using both cells at the same time in your AA? if so, then yes you can, but i would suggest wiring them in parallel. if you put the two cells in series, the RX and motors would be getting 7.4volts, and though the RX might be able to handle that, i'm sure those little 6mm motors wouldnt last for more than a few flights.
