Default RE: Skymaster Viper ..... unexplained crash??

As any pilot who has practiced accelerated stalls in a full sized airplane would know, you roll the airplane to a 60 degree bank and pull hard on the elevator. You will feel the buffet. When you release the back pressure the buffet stops and you can fly the airplane away from the stall.

Unfortunately In a model we are not given that second chance as we have no warning of the impending stall. It's over very quick.

I have been flying all kinds of models for many years, three months ago I had my maiden flight on my SM L-39.
Plane flew perfect for two minutes. In a tight bank which I thought was not to slow, I pulled on the elevator to tighten the turn (I set elevator throws to factory specs). It was over very fast. As someone said in a previous post, I stood there in amazement not understanding what could have happened. an Accelerated stall is what happened. Full fuel, 33 lb airplane, 68" wing, to slow, to much elevator in the turn. BAM! Over very quick, was for me.

If possible, keep them light guy's.
