Video: FPV Slope flying at Soar Utah 2008


I'll say first off, due to the high speeds, bumpy air, close flying, and detail of
other small/fast planes in the air, you'll be happier if you download the high
bitrate version of this video here:

For the bandwidth impaired, there is the Vimeo version
FPV at Soar Utah 2008 (10 min 5 sec)


Winds on Saturday were between 15-25mph and Sunday 25-35mph
so a bit much for the EZ Glider, but it still did a pretty good job. Can see
that the fast gliders were moving several times the speed of the EZG.
The gyros were working overtime, which you can see any time the
camera is panned out over either wing tip for more than a second or two.

Some of the flying was done visually with other people under
the goggles running the head tracker. Some was with me flying FPV.
Three other pilots flew the plane FPV style as well, but they
tended to struggle a bit with the high crab angles necessary in this wind.

Let me know what you think.

Nice video!

I downloaded the full version (147mb, yikes!) here at work and showed the guys. Some of them didn't believe it was an RC plane at first!
You're not kidding about the crab angle. Pretty impressive.
Another good one for the FPV archives!

I hate watching your videos because it makes me jealous. I'v never flown on a slope and it looks like so much fun. Great video, btw.

Awesome video!!! ...makes me want to move back to Denver... I know it's not Utah, but there were so many great hills for this out there too!

Sloping looks fun, FPV looks fun... slope + FPV looks really fun!!!

I saw your gryos in action too... what servos do you have on the ailerons?

Point of the mountain South boy does that bring back memories. I've flown both sides of the point in my Hang Glider many times. On the North side you can fly out past the interstate and over a prison. Quite a contrast flying like a bird above prisoners looking up at you from the yard. I had a nasty accident on the North side and also appreciate the excellent trauma center in Salt Lake.

Impressive video. That takes some good skills to FPV a glider and also crabing along the ridge...Nice!

Both sides of the point are now a state flight park and for the event
we got exclusive use of the mountain (no HGs or PGs allowed), which I
thought was pretty amazing for labor day weekend. Was too windy for
jellyfish anyway.

I noticed your aileron gyros keeping everthing smooth despite the wind. What's the deal with running a gryo on an standard EZ rudder- is this pointless?

Yes its pretty much pointless. The gyro movements come in rapid succession under those conditions. The small rudder will not allow for enough attitude adjustment for every gyro correction fast enough.

My opinion:
If you enlarge quite a bit, it will help with basic yaw stabilization, but I would think it'd be a minimal affect in comparison with the improvements gained from Pitch and Roll stabilization.

I enlarged my rudder considerably. I'm going to try two gyros; one on the elevator servo, and one on the rudder servo tilted up 45 degrees to (hopefully) stabilize roll and yaw. I'm doing this because I have dual aileron servos working as flaperons and didn't want to try and figure out how to make a gyro work.

We'll see how it goes, the maiden has been postponed from last Sunday to a couple of weekends from now. Life's details got in the way...I'm getting married this weekend and trying to close escrow on a house at the same time.

The future Mrs. TVDude didn't think it was funny when I suggested postponing the wedding...

I also have my ailerons set up as flaperons (actually spoilerons),
and all I did was just put one gyro on each channel. The two gyros are
simply oriented the same way down the roll axis. One of them may
be reversed, but there's nothing tricky about the setup. On a plane
that *has* ailerons and low dihedral, there's really no reason to put the
gyro on the rudder. It won't do anything particularly useful there.

Gyro on the rudder provides (increases) roll stability on some planes like EZ* ot TS2. The plane returns to horizontal orientation faster.
