I have a KitFox Model IV, with a Rotax 582 and have noticed a high-pitch
ed whistling type noise emanating from under the hood. It's not terribly
loud and has a bell's tonal quality. The frequency does not change at d
ifferent rpm settings, it only get somewhat louder. In other words, the
cycle, or pitch of the noise doesn't change with different power setting
s.
I have listened to it also with the upper cowling removed and both doors
off tryng to determine if it is caused by prop blast blowing through an
opening or hole. It's hard to pinpoint where it's coming from, but it s
eems to be strongest on the right side (while seated on the left).
If anyone else has experienced this type of thing before, or has any ide
as, I would like to hear from them. I won't be flying it until I can fig
ure this out!

I had a similar sound that was barely audible for a flight or two
before my vac pump failed on my IO-240

I opted for the non-faired version with the thinking that I would install wood
and fabric like the old gear had. I still plan on doing that, but am starting
with the wing struts first. They seem easier (snap PVC) , and I think will provide
a more significant speed increase than the gear.
On that subject, what are some alternates to the .016" metal strut cuff that is
included in the PVC speed fairing kit?

The original kits came with instructions to cover that area with fabric.
What I did was cover as best I could using one piece of fabric terminating
at the trailing ede, then making a figure eight patch that was layed across
the top open edges, glued in place at the perifery and shrunk. It came out
fine.

ok don't laugh too much.. I went to put mine on last week after looking at the
box in the garage for the last year. The aluminum pieces sent did not fit for
caca. soooo in true Alaska fashion, I busted out the good ole gorilla tape
(for test flights only). While it did make it slipperier on decent, it really
did not seem to affect cruise too much. Maybe 2-3 MPH RPM for RPM. The big
shocker for me was today when I put my new full lotus floats on (1450's) and GAINED
8-10 MPH in cruise and about 150 FPM climb over my unfaired avid wide gear
and 24" tires. I am thinking that when I pull my floats off I will be going
onto a set of Lowel's cub style gear!
