Dean,
I'm coming into Electrics from a different direction of Electric Ducted Fans. In these, most people seem to be not using seperate reciever battery packs, but using a UBEC to step down the voltage from the Li-poly to power the receiver. Any reason you guys are not doing this in pattern.

I think that the addition of 1-2 oz of weight to a 10.5 lb model for the security of an independant airborne power setup is good cause for most to run separate Rx packs.
I have heard of a number of UBEC and other BEC failures when ran with high input voltages like we have (42V).
Beyond that, there are very few BEC's (that I have seen anyways!) that have high current ratings....with 5-6 digital servos on board the BEC needs to be able to supply 5A+ on occasion...many are only rated to 1.5-3A.
