Hey guys,
I'm flying my first belt reduction, a Stratus. After 290 hours and lots of experimentation
I have been unable to find a tension setting that eliminates the
chattering when I come off the power. Takeoff is always smooth and some times
stays that way for a while, but inevitably the chatter creeps in. Cruising straight
and level at a particular setting may be smooth and then without warning,
here it comes. Usually this is at lower power settings though. It seems less
likely to produce this above 4000 rpm. This will be removed after adding power
above a certain point, too. I have my pitch at 15 degrees on a Warp drive
and cruise 100 at 4150 in summer and 3900 in winter. Flying eighty five or ninety,
which I like to do frequently, is where I have the problem..from 3400 thru
3800 rpm.
I have set up my tracking so it is perfectly centered, so it is slightly to
the rear or slightly to the front.. with the same results. I have set tension
so it is really tight and various degrees less. I have done this with two engines
and with two different reduction units.. same results. So what is up? In
static tests the belt can be observed to walk with different power settings. I
also see that the individual cogs have slack in the groove.
Of course with the chatter comes a slight vibration set up with it. My engine
is quiet, so I may be overly sensitive. Is this just the nature of the beast?
Educate me, please. Whazzup?

Replay to Scott Laughlin and Zenith List:
Your might be right, BUT, I forgot to add a key component & correction. (see

(Sorry about the major mistake, thanks for the eyes up.)

Don,
For those who havn't bought their engine yet,
the book says you need 1/8" deflection with 20 lbs pressure at center of the
span between sprockets
with the engine warm, checking belt tension initially after every 2-hours
running. With the belt really tight, I could see
the sprockets becoming a lesser pitch length than the belt and the belt
wanting to climb onto the teeth. If you've stretched the belt, it might be
advisable to get another one just to do a quality check on pitch length
against the one you've been using. I'd also want to talk directly with Mykal
on this one. Just keep us in the loop, cause this one's new to my memory.

| Subject: | Rubber canopy trim |
--> Zenith-List message posted by: "Larry McFarland" <larrymc@qconline.com>
601 builders,
After securing the canopy with screws, washers and rubber spacers,
the rubber trim was placed on both front and rear edges. The front is easy to
secure, but plans don't offer much guidance on the rear and there must be more
holding
the ends of the trim to the canopy edge and the outside flashing than glue.
Does anyone have a better solution or what's been done that improves on that.
Any help here will certainly be appreciated.

Larry
thanks. I have used two belts. The belts are not made to fill the space in
the sprockets. There is room for play. Reiner said it is to let air escape.
I know of the 20 lbs. and have used instruments to check the tension when
hot as instructed. Both have behaved the same way. Don
