Hi,

Yes I use the Powerbox digiswitch to power both the Futaba 608 receiver and airborne pack (2 of 9151, 1 x 9650 and 2 x 9150 servos) and the CDi unit in my Axiome. Takes about 250 mAh per 20 oz flight (2 1/2 P11 schedules) using 25% nitro 10% SLV oil with needle 7/8 turns out. For competition flights I use ThunderPower 730 mAh 2S packs with starting voltage 8.3V (opencircuit) and finishing voltage 7.9 V. Easily enough. For practice I also use these plus bigger packs.

Hope this helps

Keith
