Paul,
What would you recommend for a conversion from the 540 engine / gear
mount to a 2 or 3 rotor turboed mount for the F1 Rocket?  Possibly use a
secondary mount ( ala Tracy Crooks original RV4 )  although a little
heavier?
The mount has already been drilled and is presently on the bird and
waiting for a 540 or the switch to rotary.

Also, would it be possible to have the radiator and oil cooler EXITing
air out a left side duct with the turbo heat and exhaust for
better efficiency?  (Fuel lines at the bottom center of firewall.)

Thanks,
David Deffner
ps. I enjoy my rotary time on the ground in SCCA and NASA events.


Tracy has moved away from that type of mount as it is more expensive
to build and heavier than a simple mount that uses the firewall hard points.
If you send me a sketch with dims of the firewall hard points I will design a mount for
you. Also send the thrust line height dimensions and off set angles
if any. I will also need to length of the cowl from
firewall to prop flange opening. Pictures would also help.


It is possible to let the cooling air out the left side but it is not as efficient
as letting it out the bottom or the right side. Obstruction to the exit air from
the heat exchangers is not a good thing. That is not to say louvers
on the left side are not a good idea to cool the turbo. They are.
