I just downloaded the manual here

but did not found the explanations you are mentioning on the french or english version.
The idea to use a DPSI Micro DualBat 5.9V/7.2V or a POWERBOX™ ELECTRONIC SWITCH with one 450 Mah RX batt and 2 cells from the 10S packs looks great.
Due to the bad weather, I can't do some inflight test, so hope somebody will give it a try pretty soon
