Needs more power!
I have studied the photo at length. Hours and hours. After some deep technical discussions with the photographer, I believe I am ready to summarize the shortcomings in your approach.
1. You don't have the transmitter in your hands. I would grab it and try pushing the stick on the left hand side forward. I have tried this and sometimes it works and the airplane takes off.
2. I would try putting some wheels on the bottom. Align them with the airframe though. I tried putting the wheels on the other way and it didn't work worth a darn. Putting them on the top doesn't work either. I chalk it up to experience.
But Mark. Above all, you really shouldn't even try to take one of these babies off unless you are already an experienced full-scale pilot. In rare cases, people who have ridden as a passenger in a jet aircraft like me are able to tackle such an advanced aircraft but I am the exception, not the rule.
In any event, I hope I have been able to help in some small way.
