Should we have to flight develop and modify a kit that is sold for beginners by a large scale manufacturer.
This failure has really shaken my respect for Graupner quality.
I'm sure most experienced jet modelers can stop this happening by either injecting foam or resealing the door areas, as long as they know it can happen !!!!
Iam a reasonable jet pilot with hundreds of flights behind me, I doubt a beginner would have saved this aircraft, and these are the people this kit is being marketed to
