Subject: | Re: High Temperature Silicone |
I'm looking for a High Temperature Silicone to use on my Rotax exhaust
springs>>
Hi Dennis,
I am intrigued by this. What is the silicone supposed to do?. As far as I am
aware the springs do nothing but hold the two sections of the exhaust
tightly together at the ball joint.
When I was running a 503 i had the springs on, wired of course to stop them
falling through the prop. When they got rusty I painted them with black
Radiator paint or whatever heat resistant paint I had about, or replaced
them. They are so cheap it was hardly worth the bother.
What else do they do that makes it worthwhile taking extra trouble?
Intrigued

Pat, the silicone damps the vibration. Without it, the springs vibrate all
the time, resulting in much shorter life due to metal fatigue and wear at
the ends.

hi,
My flying insurance has just come up for renewal and with the detail on
my desk I thought a comparison of charges etc.,. might be interesting.
Incidentally 3rd Party Ins. is compulsory here.
Insurance is for me as named pilot plus any accredited test pilot.
Hull Ins. Value =A320,000 Transit and Ground risk (=A3500 excess on
each claim) Cost =A3250
Liability.for Bodily injury/property damage up to =A31 million
liability to Passengers/Personal articles up to =A31 million
Cost =A3240
Total cost including Tax and Admin charges =A3529.40.
For what it is worth

hi . thanks for the info. I dont know what quantity of of the silicone
you have to buy but for the cost of replacing the springs every couple
of years I wouldn`t have thought it was worth while.

Subject: | Re: High Temperature Silicone |
You can use, and many do, the Permatex Copper or Black silicone. They are rated
for 600F-700F which is more than enough. You can buy these at most hardware or
automotive stores. There are two ways to apply this and it strictly depends
on you.
One is to lay a bead 1/2" wide and a 1/4" tall down each spring and work it into
the coils. If you don't apply a big enough bead and it is thin and narrow it
will not function as properly because it has no body and strength. The second
accepted method is to actually fill the spring with the silicone. I prefer the
beed. This in fact does help with the pulsation coming from the exhaust system
which causes premature spring failure and excessive wear on the springs where
it loops connects over the loop. The silicone is not a replacement for safety
wiring the springs, but in addition to.
This is in the Rotax manual, there was an SB out on it many years ago and is a
standard practice.

Subject: | trying a new prop |
Gang,
I am trying out a Warp Drive 3 - blade 64" prop on my Firestar. I flew it about
20 minutes this morning in "perfect" air ( 60 deg, low humidity, calm). My main
reason for getting the Warp is I wanted a more durable prop.
I'm going to fly a few more times before I make an evaluation compared to the 66"
2 - blade Powerfin, but I will say the first flight #'s were pretty good. The
prop was very smooth and had a more immediate response to the throttle than
the 2 - blade.
My only concern is the HKS is similar to the Rotax "B" box in that it calls for
a max. 3000 kg moment of inertia on the prop. I do not know what the MOI is for
this prop and am having trouble finding anyone who does. I am aware of the
measuring proceedure available from Rotax and CPS, just would like to find the
info first rather than go through the exercise. Does anyone have any MOI data
on their 3 - blade Warp Drive props?

Roger Lee
Roger L/Gang:
Not to be argumentive, but I haven't used safety wire on exhaust springs in
many years. The silicone seal (ordinary/normal) works great and captures
hooks and coils should they break, preventing them from going through the
prop on our pusher Kolbs. Springs are heat treated and very hard. They
will put a ding in a warp drive prop that will have to be repaired.
If the hooks/loops and coils are sealed up with silicone seal, the broken
parts will stay in place and not through your prop.

Warp Drive 66" 3 blade CNC hub

I should add that this prop had bare, untapered blades. Can you use it as a

hurt. You might ask Green Sky, or whoever distributes this engine if they've

Flight Designs was importing the engine they always told me absolutely not,
just plain Mobil 1 5W-30. The only other thing you can do is set the idle
RPM up a bit, say 2200 RPM minimum and run a magnet through your oil at each
change. It you see iron shards it can only come from one place in this
engine, the gears.

Jimmy, I didn't see the picture, sorry. Untapered blades and stainless steel

I think you can forget about getting anywhere near 3000.

Just curious why such a concern on this forum about bending landing gear on Kolbs.
Is it a poor design ? ..or simply poor pilot technique.... stalling to high,
versus the less stressful wheel landings. ? ?

It is defiantly poor pilot technique that causes bent landing gear. The
worst offenders are GA pilots that used to the heavy iron that take time to
slow down. Kolbs are very light high drag airplanes. I was a GA pilot and
yes I have the bent gear to prove it. They slow down below stall speed very
quickly. You need to fly them to within a few inches of the ground before
you flare.

Make yourself an adjustable trim tab, that way you won't have to be annoyed when
carrying a passenger because it is no longer in trim.

With VG's you ought to be able to get that stall down below 30.
