@danny,
The 3.6 Volt is the problem, and why many F3AX models use power expanders.
When 8 heavy digital servos beat a model around in the sky when 3D-ing then they draw such an amount of power that the voltage comes down, . Just add a data logger and you will see what I am talking about. Even if you use a 5Cell pack with a low internal resistance (so it resonds quick to a powerdraw) You'll see the Voltage drop to about 2 - 2.5 V for a short moment. This will cause the receiver to stop working and possibly go into failsafe mode.

Also the receivers normally are not build to handle great power consumptions. You have the change that they will "burn".

Safety is first, specially flying 40% monsters. The insurance is also giving us a hard time when something happens and one hasn't taken all possible precautions.

But I do agrree to keep everything simple. That is why I was so pleased with the ACT receivers. The are also programmable (so you son't need match boxes) and can handle the power and dual receiver option.
I was looking doing the same with Spectrum receivers.
