It seems your model is way too overpowered for its small size. Try going for a lighter motor with a lower thrust. Your model is as it is much smaller than the actual plans. And also try using a 2S setup for the same.

The full scale one was designed to be used with a CD-Rom Motor. So you should scale down accordingly.

Low flight times. I don't think the structure is designed for such loads etc.
