Description

Par 2: Following your statement about the apparent lack of power of the Wyvern fitted with the Python, I have turned up your report G.109, and would remind you that the conclusions in paragraph 5 are as follows: The maximum static thrust for each machine is: Wyvern 1 Eagle engine 8,750 lb Wyvern 2 Clyde engine 7,500 lb Wyvern 3 Python engine 9,400 lb Nevertheless, I appreciate that there are questions dealing with power, vibration, starting etc., which must be discussed with representatives of your company as quickly as possible
