How to get your airplane out of a tree

Well, I officially flew my first R/C airplane on my first ever flight
today and got it stuck in a tree.  But.. I got it down after 3 or 4
hours using various tactics.

My Aerobird Challenger was lodged about 40 or 50 feet up in a tree and
the tail
was hooked on a branch pretty good.  We threw rocks, sticks... tied a
rock to string and tried to throw it over the branch in an effort to
shake the tree limb, but to no avail.  3 other onlookers came over to
join in on the fun.  One guy tied a monkey wrench to a rope and tried
to throw it up there.  No luck.  Fishing rod.. . no luck.  2 x 4.
Nothing.

Finally the guy with the fishing rod pulled out a large (for fishing
at least) fishing weight and we tied some very strong put pretty thin
nylon string to the weight.  On about the first or second try, I
successfully got the weight on the proper branch.  I let the weight
fall to the ground and I grabbed that end, while my friend grabbed the
other.  I pulled down over and over again and the battery pack fell
from the plane, and then finally the plane fell from the tree - into
another tree!  It didn't stay there long and fell out and then glided
into the water near the tree!  Rule #1 - don't fly near trees.  Rule
#2 - don't fly near water - at least not if you're a complete beginner
like me.

We got to wondering - what other techniques might work to get your
plane out
of a tree?  I thought - what if you got a slingshot and shot the
fishing weight with string to the branch holding your plane.  For a
situation where your plane gets caught in a really high tree, you
won't be able to throw it.  What about a archery/spearfishing setup?

Anyone have any interesting techniques they've used to get a plane out
of the tree?
Arne - 14 Jun 2004 11:16 GMT
To a point, a long pole, above that, we use a bow and arrow to get the line
up, then pull up a rope with a mini-grappling hook.

You forgot rule no. 3..... fly with an instructor. I actually paid for
lessons from a hobby shop owner. He has 25 years experience. I was flying a
$500.00 airplane/radio/motor setup. I took 8 lessons at $25.00 each.... I
still fly that plane after 5 years.... I know some clubs have very good
instructional programs (most don't), but this way I got a very qualified
person who was dedicated to helping me for an hour at a time. He had a
program set up that lead me from knowing nothing to not only being able to
fly ok, but also knowing proper ground technique, which is very important
(if you have seen someone who doesn't know it, you will understand what I
mean).....

That is the technique we use. It works well in tight areas where there are lots
of trees around and works best on leafy vs. pine trees. But it always works!
Use a sinker to get a fising line over the plane or nearest branch. Haul up a
stronger rope. Then pull like crazy and the plane will flip down. You may have
to repeat several times if it sticks on other branches.
For a total cost of around $10 for slingshot, string, line and
sinkers...reasonable. I also keep everything in one box and can toss it in the
car easily when needed.

Only need a chainsaw, that would be enough...

On at least three occasions, we have retrieved planes from a tree by shooting
the branch holding the plane with a 12 Ga. shotgun. In all 3 instances, only
one shot was required for each retrieval to sever the offending branch. Of
course, we are out in the country (outside city limits) where discharging a
shotgun is tolerated. The shotgun was a full choke model and relatively large
(#2 shot was used). We have also resorted to the chainsaw several times. The
landowner allowed us to remove the offending tree. Other techniques we have
resorted to are climbing the offending tree & lower the plane with a rope (this
is best accomplished by enlisting the aid of the younger guys). We have also
used a 20 ft ladder to get part way up the tree, then attach a rope to the
plane using a 15' length of plastic pipe. Or just use the pipe to shake the
tree. Our field is bordered on two sides by woods & flying over the woods is
common practice for us. Hope this helps. - Ray

forget about using a bow to get the line up there.  It won't work. I tried
several times.  The arrow is to light. Eddie Fulmer
Arne - 15 Jun 2004 11:08 GMT
The arrow isn't too light, your line is too heavy.... as mentioned, we do
it.

I have told this story here in the past, but here it is once more:

At the club one day we tried aero towing, and it went well.
The Lady was lifted high and enjoyed a nice glide, after some
boasting the pilot stated he could make one more circut.
No deal.
Looks way short, hard bank, tip stall, roll/dive, recover, balloon, Tree.

The local know-it-all says he has the answer. Ties a old receiver pack
(or something like it, maybe it was a tennis ball) to the end of a kite
string.
On his second throw he loops the line over the fuse at the wing.
Sort of diagonal, left LE to right TE. Maybe two and a half times
around or so.
Gives us all a big "I'm the greatest" smile and slowly takes the slack
out of the string. Then he says "I'll just pull her down, get your thumbs
on the sticks"! Mister smart guy gives it a mighty yank and the string
cuts the fuse clean in half. The plane does not move.
The second pull tightens the loop all the way to the wing joiner.
The fuse folds almost in half and executes a slow
and graceful spiral decent to the parking lot.
Sort of like one of those helicopter seeds from the maple trees.

So watch it if you use that method.

No one ever said you can always get your plane back in working order!
If you put it high up in a tree...you can consider it as a total write off. You
can sometimes recover it, parts of it, most of it, some of it. But whatever you
do get is a bonus!

Once offered some kids $20 to get my Super Stunts 60 wing out of a tree.
Everything else managed to make it thru the branches and down to the ground
in re-kitted form. The wing was toast also but it did have 4 servos and a
reverser which were still good. They managed to get the sucker down and I
gladly paid up.

Best way is not to fly there in the first place.  I learned that about
25 years ago, and haven't lost a plane to a tree since then.
Red Scholefield - 16 Jun 2004 18:58 GMT
Sounds like one of our club "experts" - he never crashes . . . . .  some of
his planes may be suffering from dry rot or terminal hangar rash however.

We've got the real deal: a fellow who flies his airplanes and never
crashes.  He's also a very generous unpaid instructor and he
mows the field routinely without griping.

We gave him the Crashomoseus Award last Christmas for a mid-air
that wasn't his fault.  We figured this was a lifetime achievement for
him that deserved recognition.  :o)

His name is Ron Dunlap.  We can't canonize him officially until he's
been dead for 25 years, but he's already a saint in my books.

Don't fly over anything you can't afford to crash into.

This is just a minor point. The further away the plane, the higher I keep
it. I had 3 'flame outs' in the past week. All 3 dead sticks easily made it
back to the field (and out of the corn) and were within 50 feet of me at
stop... Altitude is your friend .

There are five useless things to a pilot.  Runway behind you.

No. I fell asleep! But I was looking forward to seeing it, as the
advertisements interested me. How about a re-cap?

Update on my Aerobird Challenger... I have to say this seems to be a
pretty
tough plane.  It still works even after being totally submersed in
water.  I let it dry off for a couple of days and have no problems.  I
flew it around today and one wing that was already weak gave in and
the plane did a spiral of death from 50 feet or so and hit very hard.
After taping up the fuselage and adding a support to the wing it flew
with no problems.  I flew it some more and got it stuck
in a tree again.  Used the rock on a string and got it down and flew
it some more.

Maybe I'm lucky... or maybe this plane's number is up?

That's actually true of most electronic items, and most of our planes.

When they get wet, ideally you rinse out the water with distilled
water (especially if it's dirty or salt water that got in it) and then
open it up to let it dry out quickly.  A fan blowing on it is good.

The purpose of the distilled water is to get rid of any water that
might leave a residue.  It may seem counter productive to get it
wetter than it already was, but it does work.

It's important to get it taken care of quickly -- otherwise parts can
start to rust, and that's generally bad.

I have done somewhat the same thing as the shotgun approach but used a .22
cal. pellet gun instead.  That way there wasn't as much chance of collateral
damage but it was harder to hit the branch.  Of course it wouldn't work on
very large branches, but normally it is the small branches that are snagged
on the landing gear or something, that is preventing the model from sliding
off of a larger branch.  It is quite a different type of target practice to
lay on your back, on the ground, while shooting straight up in the air.  I
wouldn't recommend doing it with anything more powerful.  Remember that what
goes up, must come down.  That applies to bullets as well as airplanes.

This question shows up about once a month!!!

New techniques are suggested almost everytime!!
