Great! But the design…. Could be more durable. One of the MKII’s broke after only a few sessions. Never dropped, but must have knocked against something somehow. Already bought one to replace it.

This upgrade is a must. DominatorHD

Took me a min to get these because I wasn’t sure they would make a difference but boy do they. I swapped the top right and front right ports internally like Bardwell said.


Didn’t use them du to a problem with the system.Had to sent them back to Rotor Riot.

Hello Claude,

I went over your returned items yesterday and the only issue i found was the VTX for the Avatar you had was dead. I went ahead and updated the goggles and the New Avatar system to the latest released firmware and bound them together for you. Everything is shipping back out today ready to go. If you have any other questions you can reach us at Support@RotorRiot.com
