pulling the wing and engine

The engine on the Curtis pusher is an OX-5 V-8
Originally the First Curtis airplanes offered a 4 cylinder and 8cylinder engine.  The Rheims Racers winner of the Bennet cup in France in August of 1909 was powered by a V-8.  Other planes that were sold to the public had a lower powered 4.
This engine was built for the Army in 1919 .  It has 90 HP and ticks over at 1,400 rpm. 
In ordered to remove we had to pull the top wing and hoist the engine out.

Note the position of the pilots seat. It was inches in front of the radiator and engine.  The exhaust ports were next to the pilots head .  It must have been deafening .
