Many of the HV servos I use have an input voltage that ranges from 6.0-7.4V. So, you don't have to change out any servos. You just get less torque. On a pattern plane the full voltage and torque from an HV servo is not needed. Trust me.. regulated voltage from a Powerbox switch to an HV servo works great. I have a 2M patternship with that setup.

I order a New backup system yesterday so when it arrives I will give that a try.

Which connector was bad?

the connector from the esc to the RX , I took a Close look and found all off them bad .
How this happend I dont know maybe they have been like this from the beginning, it has always been a bit to short so I change it and got it a bit longer

Nope I think the signal and maybe one off the other ...lost Power (motor) and RX feed from the bec , luckely i had the backup Power from a smal lipo so I landed outside the field the plane flew again today,,,so no big damage.

The 500 mAh pack is strictly for backup and the RC system is normally operating on the propulsion power pack in both cases. In the case of the HV system the 2S LiPo is being charged by the motor pack. In the LV system you will need to charge the 2S LiPo periodically depending how much time you use it to test and tune with it.

Just wondering if you're still using this configuration (i.e., using a 2S lipo directly in parallel with the Mezon BEC). In my helicopter fleet, I use Kontronik Kosmik and Jive Pro ESCs which are specifically designed to have a 2S lipo placed in parallel with the BEC output. However, the JETI user's manual for the Mezon ESCs doesn't make mention of using a lipo in parallel with the BEC and I would assume some ESCs could be damaged by using them in that configuration.
