Here is my take on this... For what it's worth.

1. I spend hundreds of hours building a "scale" plane (warbird or civilian). When the 3Der's are hovering out past the runway that is not a problem to fly around them. Where I have had & seen problems is when they are entering and exiting the hover. I have seen three near misses between a "scale flying" plane and a large 3D aircraft just this year. I for one do not wish to risk my planes and investment of time and money in that manor so I choose NOT to fly a events where large 3D flying is allowed unless the flying is segregated.

2. Most 3D pilots are very skilled but they are expecting other pilots of other types of flying to be just as comfortable with their maneuvering as they are. This is just not the case. It is a totally different type of aircraft and flying it is quite a bit different.
3Der's NEED to understand that.

3. This IS an issue for all fliers. I do not want to see ANYONE limited in their style of flying but I think this issue needs to be addressed by the AMA. I am a big fan of less is more but I only see two alternatives. The first is to segregate the events into separate events. The second is to segregate the flying into separate times (this is what most CD's are trying now). Will some success but not always.

We all enjoy this hobby but we have to mutually respect each other's skills and limitations. There are always going to be individuals that ruin it for everyone at these events. The secret is to be sure a let the CD know what is going on ASAP. If they do not resolve it. Speak to the person yourself!

Fire away!
