I don't know if there's some standard emergency protocol (SEP) -- that's what I'm hoping to find or learn -- but in pondering on the scenario I'd think you should have 2 goals in mind. 1)- Keep it as close to point-of-loss as possible, & 2)- Do what you can to minimize crash damage when it contacts the ground (presumably still unseen).
You guys agree, or argue with those premises?

And, what would YOU do to achieve those goals, given no 'SEP' alternative?
I have a couple things in mind, but want to hear your ideas without my influencing.
And perhaps needless to say, I've faced this very condition so know it happens -- I was just lucky enough to pick up sight of it again. Losing it was no happy feeling!
Throttle - OFF
Select - Max rates for controls
Sticks - Hold for spin (Full UP elevator, Full Rudder and Aileron as required)

Same procedure if you lost it in cloud/fog.

Pretty much agree with all that was said. Full up elevator, full rudder and make sure your name and phone number are in the bird someplace.

That being said, now my story. Back in the days when I was a bit fanatical about glider flying (someplace I seem to be heading again), I lost one of my 2.5M planes when a little gust of wind blew a piece of dust in my eye. I was already higher than common sense should allow but what the heck. It was a great thermal. I never did spot the plane in the air. I put a rubber band on transmitter and held elevator and rudder and set the transmitter down for a few hours keeping my eyes to the sky. I ended up going home without my plane that day.

About a month later I was flying in the same place and because of a radio failure I had to take a hike to retrieve a plane. A little to the east of where we stand to fly are a bunch of little hills made by the dump trucks dumping some fill from some construction site. About 200' from where I stand, between two of the little hills was the plane I lost a month earlier. It was undamaged. Charged it up and flew it the same day. Its funny how the eyes and mind work sometime. I had to look right at that thing several times while it spiraled down and ended up so close. At any rate, it turned out to be a happy ending.

A few conversations that I've had with eye specialists and pilots since then told me when things like that happen, never concentrate or look hard at the center of your vision. It's a blind spot. Let you mind look to the peripheral areas.

Hmmm... Interesting info.
I'm definitely going to try that out next time someone has their plane specked out.

Agreed and I figure our actual reactions would probably depend on condition, landscape, setup and type the model was lost while flying. Generally would try to reduce speed so as to minimize impact force. Power off/idle if model has motor or engine. If model has crow/butterfly would likely use it along with some rudder, otherwise elevator/rudder and maybe a small amount of counter aileron to flatten spin in hopes of slowing decent rate.

When I thermal soar for fun/sport, there's no caller standing next to me and no extra set of eyes on my glider so i don't take the chance. I range far with thermals moving away from me but not as far out as when having to at TD contests.

At thermal duration contests each pilot has a buddy call/spot/time their round. With good communication a Caller can be an extra set of eyes when your glider is a tiny dot, basically so far out that when one of us can't see the model that means the other will likely soon lose sight of it as well and in that case better to head back or go no further out than current circle. Some push themselves and fly far out because they don't want to give up on the thermal they are in and potentially lose out on points. Have seen gliders lost at TD contests, not fun
Personally I have lost my glider for a few seconds (which seemed like an eternity) in various contest rounds, however thank goodness my caller/buddy was there to help guide me through the back side of the thermal circle where I had lost it, now that was extremely fun and gratifying

Hi there, some news of my phoenix;

After a slight damage in the wing screwing area, I totally rebuilt the system: It's now rock solid and only 2 velcro to assemble on field.

Beside of this I sloped it this weekend for the first time: He flew great, one of the best to take the small lifts of this slope.

That's a really nice fix you did there, traumkumy. I like the piece you made between the wings.

I do not have the controls at full throws in failsafe. I do what planekrazy did: Full crow to slow the plane down and a slight bit of rudder to make it descent in circles. Naturally throttle is off.
And I have my phone number on the plane.

Nothing really special, it's a standard pine bracket laying in my garage, 1cm of thick.

I used this opportunity to flatten the V longitudinal because I fly with a 83mm CoG (already discussed in this thread) and to create a kind of common latching pateform, not oly for this pair of wing, but for all the next-ones (with different airfoils or length) to be used for the Phoenix, but also on other upcomming self builts bodies.

Nice rebuild Traumkumy, looks better and is more functional than stock. The double-spar and quick-release velcro are awesome too, great work there. Hats off to you.

Been riding thermals here and there with the Phoenix 2000 for about a month now and really enjoying this hunk of foam. Started using a 1000mAh 3S pack in rear tray position to play with CG between 80 and 85mm. My preference is when wind is gusty set CG around 80mm and in less gusty/more consistent conditions set it more rearward.

We finally had some great weather this past weekend so took some video with a HD keychain cam velcro'd on the canopy. Last night I uploaded them for sharing in case anyone is interested (youtube newbie here, these are my first uploads). Tried to get footage of my friend landing his Eurofighter at end of part1. In part2 the 2nd 7-minute thermal took me out higher and further than the first one, there was more thermal there but had to come back home because my knees were shaking and my neck was aching

Thanks Planekrazy.

I was at the slope this morning, there was lot of wind but also, lot of lift.

The phoenix shown it's limits in these conditions, because ailerons and elevator are not effective enought. In a stall turn a gust put the phoenix on its back and during my really slow recovery manoeuver the wind pushed it at the top of the hill: I did a fantastic leek (as we said in france ) from around 5 meters.

The phoenix resisted very well, only the canopy blown in 2 parts (!) but no other damage taken. A quick bond with cyanoacrylate glue and I was able to fly all the morning... without retrying stall turns.

A friend adviced me to use nylon bolt to have a kind of fuse somewhere. I think this advice is also applicable to stock wings setup, because crashs often snatch part of EPP with the stock bolts.

Hi Giancarlo.
Welcome to RC Groups and this thread!
Many of us with the Phoenix 2000 use the HobbyKing Turnigy 2836 motor and the HobbyKing Mystery 40A ESC. Both have worked very well for this glider.
