Hi, before we get too far along on the jet stuff;
first you can slow the blade in the exaust side down but 2 things happen, 1
efficiency goes  to heck in a hurry and the exaust/rotor blade temperature
skyrockets. The higher velocity exaust will eat the rotor blades in very
short order. Jet engines exaust temp has to be watched carefully, otherwise
overheating will destroy the engine in seconds...cul brian f.
