Howard,
Below is your original post about the stab problem .
My name name is Howard.I bought a rare bear 90 size had a stabliser seperation which was a manufacture problem.they said it was my fault and it wasn;t my fault. i would sure like to know what that means on real.it happend on the second flight at around half throttle at level flight.there were seven instructors at are fly in when the plan crashed.they looked it all over and come to the same conclusion. manufacture problem. i sent pictures and the rear section of plane. this was going on over a month.well they said they would send me a new plane for there cost which would be not much less then I payed for the plane. well I guess won;t ever buy from ace hobby & thunder tiger again. take Heed.

And here is Steve's (Ace Hobby Distributors) response.
The Rare Bear tail must be built correctly to have the required strength. If the tubes that hold the horizontal stab are not installed correctly, it will fail. When we here at Ace Hobby Distributors inspected Howard's crashed Rare Bear, we found the longer tube had been pushed through the third rib on one side breaking it. The tube was therefore about 3/8 inch to short on the other side. This allowed the stab to flex and finally break. The Rare Bear we have built is still flying and flying well, as are many others. Ours is somewhat over powered with a TT 120 2c, but this was done to test the airframe at greater power levels than needed to fly the plane.
As long as the kit is built properly, it should fly well.

As I already mentioned in a previous post, both carbon fiber tubes for the horizontal stab in my RB kit were too long and required minor trimming for a perfect fit. Based on the autopsy reports you were not careful enough when fitting these tubes and damaged the internal structure of the horizontal stab which subsequently lead to an in flight failure of the horizontal stab.
Time to put it to rest.
