Hustler 58,
Don't know if the otherJWM teams are full time jobbers of scale jets. What about David Shulman on TEAMUSA? The JWM rules don't specify any job requirements for the entries, only model weights of 13.5 Kg and 20 Kg for the 2 classes flown. ARF's are acceptable as well as hired builders. Check the rules at www.ijmc and details of the 16 country teams at the 10th JWM link within that site. Incidentally, the proper name is "Jet World Masters" not "World Jet Masters" - a very common mistake even by former competitors.
