Hitec is very good and low price with repairs. They offered to replace the rear case on my 9 year old Eclipse 7 for $15 including return shipping. Contact them at
www.HitecRcd.com and tell them your problem.
On mine the part of the case fell apart where the handle mounts. Someone at the field told me cases do not like glow fuel and after lots of years they get weakened.
