Ground testing my new 50% cub in preparation for maiden flight
lost all communication to plane.
After checking radio batteries etc. I put a voltmeter on output leads
from regulator to find that only 2.25 volts was coming in to
power expander. What happened and why. More alarming is both leads
read the same why no redundancy? This is a brand new super regulator.

Hi Bob,
The SuperReg is not a redundant regulator, it supports redundant batteries but it has only one regulator. I am not sure why you are getting 2.25V. Also, if this is really a SuperReg and not a TurboReg you should not be using it on a 50% cub. I will not know what is wrong until I see the regulator. Can you send it back to our Tempe address? I will address it right away.
