Hi,Excellent work!
I have some 5.1 and 5.7v reg already by hand i will use ... good it was the same type then!
The battery-pack in the Integral is placed rear aft for CG reasons, and not so easy to reach .. i guess if i use Li-po, it should be removed when Charging !? ( safety reasons, and access to the balance-plug)
The backup is no problem to use Li-Po, cause i can put it in and accessable position.

The two battery, two switch, two regulator approach with two cables into the receiver is probably the safest approach. In pattern planes where weight is so important, I use a single two cell Li-Poly 900mAh pack and a Jaccio Perfect switch harness that serves as a solid state switch and a voltage regulator. I have never had or heard of a sudden catastrophic failure in a Lithium-Ion cell or a failure of a solid state switch in a model airplane and we've been flying them for close to ten years. In my electric powered planes I use about 50 mah per flight so I could use a smaller pack. I have always charged my Lithium packs in the plane.
By the way my wife's name is Jacci O and hence the name.
Meeky, I would be wary of a 3.5 amp BEC. Especially in a glow powered plane with digital servos. You can draw one Amp without any servo movement. I'd like to know how they behave when the current exceeds 3.5 Amps. I've heard the folks flying 2.4gHz receivers having major problems with voltage drop outs with BECs.
