Hi. I am planning to build a F1 Rocket in the future.

I have already acquired a 3 blade Hartzell and an engine.

I have not ordered the airframe kit due to time and money constraints, and due

to anticipation of further improvements to the kit. 



Now for the question. My engine is a TIO540-AG1A.

Basically, it has 270 HP, dual mags, parallel valve, and long reach heads.

The engine also has the large hole mounting ears.

I have already gotten rid of the turbo and all turbo related accessories.

The  fuel servo mounts on the rear/center/bottom of the oil sump.

Is this going to cause a clearance problem with the engine/gear mount?

Are there any other issues with this engine that I should be aware of?



Thanks, Wayne

<< The  fuel servo mounts on the rear/center/bottom of the oil sump.

I should have been more clear on the mounting of the fuel servo.

The fuel servo mounts on the rear/center of the oil sump.

The inlet for the fuel servo faces the rear of the plane and not

the bottom of the engine.

I would recommend that you at least change the sump on the engine to the

C4B5 type sump.  I am not sure what long reach heads are, but if they stick

out any further than the standard heads, the cowlings will probably not fit

properly.  You might want to check for correct counter weights, fuel pump

and also the crankshaft flange to see if these are compatible. Also find out

how much this engine weighs compared to a C4B5 block.  You do not want any

more weight out in the front of this plane.
