but not sure why the need to have hot exhaust blowing on tailboom constantly....?

This is inherent flaw in my opinion.  Poor design.  Many other ways to configure exhaust stack to where it does not try to melt a critical part of the airframe off everytime you hit the start switch.

Just bad engineering.

Blow that $#!t off to the side far away from my tboom please, thank you.

Worse than the Dictator with his incessant need to have a "pointy" rocket.

Try again Nadal!
