There can be issues with the video tx "swamping" the flight control rx's in your model. It should not affect other users, but you could have a problem with your model since the power output of the video system is higher than the power output of the flight control system, and it's in close proximity to the flight control rx's.

Follow the manufacturer's install recommendation closely especially with regard to clearance between components and do some extensisve range checks. If you're using the Spektrum/JR system, make sure you have an rx which is Flight Log capable and track those numbers.

We have one club member who likes to play with the airborne video systems, but he went with a 900MHz video system expressly for the possible interference issues.
