Hello,
I've just converted my Oxalys to 170CDi power.. After a near miss earlier this summer, I've been more aware of the current drain of each flight!
On my Oxalys, I've had a few different set-ups regarding engine/servos.
Currently I'm using JR DS8355 for ailerons/rudder/elevator and a small JR Digi on throttle. I've connected the CDi-unit directly into the RX through a digi-switch.
RX-battery is a Graupner LiFe 1100mAh.

Last time I was out testing, I had 3 flights of approx.8min each. This drained a total of approx.800mAh from the battery! (I charged 800mAh after flying). I thought this was a bit "scary", and a real wake-up call!..
But the major question is: Is it normal? (Using approx.270mAh/flight). If so, I'll have to invest i a slightly larger RX-battery...
(Yes, I know electro is using less than 100mAh/flight, but I'm not there yet!).

As a comparison, using JR DS8401-servos and YS170, I avaraged 110mAh/fligth.

Any thoughts?
