REFLECTOR: Nose Gear Damper System

Tue Oct 11 10:00:22 CDT 2011

Nose gear damper systems are in and ready to be installed/shipped.  Attached
is a photo of the RG version.  (We will be testing this today).  The FG
version is approved and ready to go.  The cost is $600 plus shipping.  This
will include us drilling and tapping your Nose Gear Fork and installing the
bracket.  If you aren't flying yet or have your nose gear strut out for some
reason then we can install the stop and insert if you send in your nose
strut as well when you send your fork.

Thanks,

John

Kevin,

I only have two large NACA's that connect to the engine plenum.  I don't
know about a small third scoop.  I've seen pictures of it but don't know
what its for.

>> Interesting story about not having a drain hole in a low mounted intake
scoop.  I was washing my plane last summer.  It was about 6pm and the
airport was deserted. Finished washing and wiped it down with a shammey, got
in and was going to taxi it back to the hanger. I was pretty aggressive in
spraying it down with water and rinsing as it was really filthy.

another shot and hit the starter, it made an odd muffled kind of sound and
didn't start?  Hmmm... Not like it at all.  I bent out the door and down to
look back and under saw a fluid dripping from the drain holes in the cowl
which seemed OK, I had just sprayed it with water.
>>
>> I gave it another short burst of fuel and hit the starter, still nothing.
>>
>> Got out and walked back to the rear and bent down to see if that was
water slowley dripping from a drain hole, I rested my hand on the intake ram
scoop below the fuselage. IT WAS REALLY HOT!
>>
>> I thought, SHIT THATS HOT! I touched it again to convince my unbelieving
self that it really was hot, IT WAS!
>>
>> I ran back to the front and opened the throttle, idle cutoff on mixture
and held the starter on for about 30 seconds.  It actually coughed a few
times at about the 15 second mark and seemed like it wanted to start.
>>
>> I ran back to the rear and the intake was a bit cooler.  In a minute it
was definitely cooling off. I removed the rear part of the scoop and it was
partially black in side as was the servo intake tube. The filter in the
front part of the scoop was partially melted. NOthing damaged but the filter
thank god.
>>
>> Without a drain hole the rear part of the scoop filled up with I don't
know how much water, then when I gave it a shot of fuel(probably too much)
some ran down and probably floated on top of the water.  That fuel ignited
somehow, maybe a back fire!
>>
>> I now have a 3/16 drain hole in the lower part of the scoop. I had not
put one in because I was trying to seal it really tight for ram pressure in
flight and sucking dust during taxi.  Now I sacrifice a minute amount of
pressure during flight and probably don't get but a few specks of dust
through that little hole during taxi...
