[NSRCA-discussion] Hacker C50 Comp fan FYI

[Verne Koester]

Looks to me like you could get the same effect by removing the phenolic ring
off the old one. I flew a whole season with the ring removed a few years
back. No change in temps or performance.

FYI, I just received a new fan for a Hacker C50 Comp from Aero Model and at
first I thought they sent me the wrong part. But it turns out Hacker made a
change to the fan. You need to remove the old fan and the brass spacer and
clean the shaft before installing the new one. I also added a couple of 6mm
shims to match the combined length of the old fan and brass shim. The new
fan does not have set screws, it needs to be green loctited in place.

 

I attached a picture with the old fan and shim on the left and the new fan
on the right.
