Hi All
I agree with what Ehab says I think that it is very prudent to test fly the airplanes and stress them beyond what you would normally see during flying.
We have a team of volunteers in Hawaii that works with Eric of Airpac Models to test fly all of our new stuff. I almost have the Skymaster 1/6 F-16 ready to test here as an example. Many people just don't hear about what we do here because we just don't bother posting every little thing that we do. Most of us have full time jobs to pay for the jet stuff and we just get to darn busy between the building and work

. Our main goal it to make sure that the things that Airpac sells are safe within reason, of course we cannot afford to test to destruction so we try to push it as much as we can with the aircraft. If there are some big problems we usually find them. There have been several design changes to Jets that Airpac sells due to issues we found during our testing. Other dealers that sell the same kits as us also were involved in testing, Ali from the UK, Morne from South Africa.
We also do low speed flying testing, stall behavior, hi AOA behavior, CG optimization. You can do a reasonable amount of testing for low cost I agree.
In all its a lot of work for us here but we get to fly some cool jets, and it's sure great to get a new jet every couple of months! Having said all of this, we have not gotten an F-4 to test yet, or the L-39. I’m waiting like the rest of you to get ours!
Nice to see you on RCU again Ehab!
