I flew the Cermark MB339 prototype at the best of the west . I let Bill Fly it although as some of you know it had elevator problems and Bill time was cut short. He did a remarkable job saving the plane. Although there were many " experts" on hand to give their opinion, only a few things are for sure after I* had time to clean up and inspect the damage. 1. The elevator servo was failed pst the full up position. 2. The right stab stub spars were sheared off at the side of the fusalage. there were no marks of any kind to indicat they came off at impact, 3. Two elevator hinges were torn and two were pulled out ( possibly improper4 installation on my part) 4. The spring steel 4-40 solder clevis was not attached to the elevator torque rod.
The good news is the airplane hase been repaired and I flew it at El Toro in the Scale contest in the fun scale division. ( Thanks Larry!) I had a great time during the contest and the plane flew very well. The performance with the Jet Cat P80 is great. The changes I have made are include withthe production kits. A 6mm carbon spar has been included for the stabilzer. I am useing springair retracts with 3/16 wire struts ( a little stiff ) and I'm using a Tamjet pipe with no bypass. Bypass is included with the kit for those whe like bypass ducts. I think all of you who are reciving your kits will have fun with this easy to fly model.
Good Flying, Mike
