What is the allowable engine weight on an Horizon Aircraft?
 A Midwest 2 rotor now owned by Diamond Aircraft is 100 HP and weighs
 about 110 pounds. Contact them for price and availability.

 Hi Charles,

 I have used Rotorway RW-100 water cooled aircraft engine that is 100 HP.
 It's all crated and ready to go.  It was going to be used on a VariEze

but

 I am building a long EZ and it needs a bigger engine.  Make you a good

deal.

What does it weigh Richard?

Paul Lamar


According to my paper work, 178 lbs with starter.  I never got a starter.

Also isn't that HP rating at some high RPM say 3500 to 4000? You will need
a gear box in a case like that. Additional weight.

100hp at 3000RPM, it has the same size prop flange as the O-200.

Richard, I know a fellow who ran this engine on his Varieze. 
He said the 100 HP rating of the Rotorway engine was very
optimistic and it really put out closer to 80 HP. He based this on many comparisons 
of his aircraft to O-200 powered aircraft.
