| Subject: | Re: RV-10 Glide Ratio |
I don't have a real AOA and have never flown with one so I just practice a lot
at solo and gross. The family understands the importance. I do not practice with
full baggage, low fuel and at my aft limit with the family on board. I already
did that with dogfood in phase 1. So far, no tendencies to enter a spin. I
unload and raise the wing with rudder then gently add power back in. There is
plenty of tail buffet warning without flaps. The GRT has a "derived" AOA that
I calibrated, but I feel looking out the window with the feel in the seat and
sound do more for me. I went out yesterday and did some power off stalls with/without
flaps and level/30 deg banks. Also some no flap landings. After a while
you can feel when you are at the "right" speed with or without flaps. Pulling
that prop back to 640 rpm really makes a big difference in glide. I get a little
engine shake at that low rpm, something I did not notice on David Maib's
3-blade during transition training. It does seem to have a slightly better glide,
possibly due to less drag on the 2-blade and solo.

Certainly drag is important, and others have mentioned ways to reduce it (low rpm
on the prop, full throttle, stop the prop). Depending on what happened to the
engine you may or may not be able to control these things.
Curiously, while weight affects the optimum glide speed it does not affect the
glide distance, no wind. In a headwind you can glide further if you're heavy,
vice versa in a tailwind.

| Subject: | Max RPM adjustment |
I have the standard MT governor on my RV-10 (IO-540-D4A5). I had the max
RPM set to 2700 RPM initially, but over time it has been declining slowly,
to the point that it's about 2640 on climbout now, at 2+ years and 200+
hours. Is that to be expected (i.e. I should just adjust the stop screw) or
is this indicative of a problem requiring further investigation? The
governor appears normal and in all other respects operates normally.
Thanks...

I do not plan on removing the front floor panels from my QB fuselage,
but I do want to look under them. Thus I am in the market for an
inspection camera which I assume will come in handy in the future. I
have looked at the one Costco sells and wonder if anyone has used it?
Camera recommendations from users would be appreciated.

My MT was set at 2700 and still runs between 2690-2710 depending on temperatures.
I would ensure you are hitting the high rpm stop when prop knob is fully forward
and ensure the adjustment screw has not moved. I doubt it is normal wear
and tear. Call MT. They may just tell you to readjust. Let us know what you find
out.

I don't have one but if I buy one, it will have to fit through my spark plug hole.
They would be great for valve/piston/cylinder wall/muffler/corrosion inspections.

A friend of mine just bought this one from Oasis Scientific on Amazon

So far, for $80 it looks ok.

I'd back the screw out a bit and see if you get the RPM back. Make sure
you have full travel to the screw. If you get to the screw but don't get
the RPM back then I'd think your pitch stop inside the hub has changed but
that seems very unlikely. Try the simple adjustment first and like Wayne
said if you feel calling MT is helpful then by all means do that too.

Only make very small adjustment at a time. You do NOT want a prop
overspeed. You want to achieve about 2650-2670 static rpm on the ground,
which will get you darn close to 2700 on takeoff roll.
