 I AM BUILDING A LARGE 8-10 PASSENGER PLANE

 AND WOULD LIKE TO HAVE AN ENGINE

 OF 600-800 HP

 AFTER READING YOUR WORK IT LOOKS TO ME

 THAT THIS WILL NOT BE TO DIFFICULT

 HOWEVER I DO NOT HAVE UNLIMITED TIME TO DO ALL THE

 RESEARCH NEEDED IS THERE A FIRE WALL FORWARD COMPANY

 I CAN BUY A ROTARY PACKAGE FROM?

 BEST REGARDS

 I suggest a PT-6 :)

Try RX7 Specialties in Calgary, Alberta, Canada. They do not do to my
knowledge a firewall forward but they can put together an all aluminum 4 rotor
for you. Just search for their web site and contact them. They have been doing
R+D on other things, so they do seem to be open to look into what you need.

IMHO a four rotor will not be up to a continuous 600 HP in an aircraft application for long let alone 800 HP. That size airplane requires a heavy duty engine indeed. Try a P&W R1350 or P&W R1830.

You could also use a Russian Antonov AN2 radial :)
