Duralite and Gyro 601

[SKYBLUE]

Hi guys,
Im using the 4000mah duralite with a fail safe 5.1v regulator. After hooking up everything and turning on the power switch, my 601 Gyro screen shows 4.8v. I hooked the same regulator to a friends heli and his 601 screen shows 4.8 too. I know the gyro should be reading 5.1v but its not, so I thought that the regulator was bad so I called up Duralite. The Duralite staff went through my set up with me and made sure that everything was hooked up correctly. He told me to hook the digital battery checker (Futaba BR-2000) to the output line of the regulator to check the outputed voltage. The battery checker screen shows 5.1v, so we know the regulator is working correctly. But why is my 601 and my friends 601 screen showing the voltage at 4.8v? Does anyone know why or have experience with this? Should I exchange for another regulator or am I fine flying the duralite system as it is? Inputs are appreciated, thanks guys.

Skyblue, as long as your voltage on the 601 amp isn't less than 4.8, your regulator output is at 5.1, and your pack reads approx 7.6ish with a full charge and a 1amp load you should be fine to fly. As I'm sure you know just don't go below 6.9v with a 1amp load. Also make sure your using the black lead and not the yellow when doing a load test. The yellow should only be used for charging.

All of the set-ups I've seen using 4000mah packs, 5.1v regs, HD switch(not Duralite) and the GY601 including my own systems read 4.89-4.99 on the 601amp and 5.1 on the regulator output. Yes there is something that is drawing it down about a tenth of a volt but I wouldn't say that it isn't normal.

Call Duralite and Jack will take care of you if you feel the need to have them replaced but I'm not sure that your 601amp will read any differently.
