working on an old Pica kit P-6E..,near the bottom front of the fuse is part that may be a radiator, oil cooler or something else. There's nothing on the plans to indicate what this is....please advise

thanks Howard

you sure it is not a Royal kit? Did nt know Pica ever had one. I believe you are correct in that it is the radiator

my bad it's a Royal kit

I have the same Royal kit and Yes it is a radiator

looking along the top of the fuse in front of the pilot something looks like it may be a gun sight..am I'm correct in this assumption. no mention in the manual or plans

thanks H

gun sight is about 4" long and 1/4" diameter on my Royal P-6-E
