Transmission - Spiral Bevel Gear Set:

Re: Safety Factors used in helicopters:

FORM: Gear - Bevel (spiral) - Horsepower (Hamilton)
	The Pitch appears to be Module 4. The tooth count is 9 and 45. The face width is slightly over 1". The gear has an overall diameter of 7". The circular pitch is approximately 0.5" on the circumference. Dennis Fetters said that this gear set is used on the 1 and 2 seater. Their literature mentions a 2:1 or a 1.2:1 safety factor (depending on how you read it).

A sheet of literature says; "The main transmission contains a set of ground spiral bevel ring and pinion gears, designed and manufactured specifically for the Mini-500. The gears are designed to give 2,000 hours of use with a safety factor of 1.2"

Revolution lists their engines at 67-80 hp for the 1 seat and 138 hp for the 2 seat. The lines below are therefor their theoretical Service (safety) Factors based on the Hamilton calculations above;

	1 seat Talon	2 seat Voyager
Durability SF	0.61	0.33
Strength SF	0.71	0.38
