Plane Rescue - Getting your plane out of the tree
It doesn't seem to be that high up, but as you think about what you have in the car/at hand you realise that 5 metres is to far. The days you could scale a tree like that are far behind you, and instead you have found a stick or rock which you have been throwing at the plane in the vain hope of dislodging it.
Yes, after parking my easystar in a tree the other day due to a misjudged approach I was reminded just how hopeless this situation can seem. However, we managed to get the easystar out and I thought I might share how we did it, as well as some of the other useful techniques I've heard used.
First and foremost - don't bother throwing stuff at the plane. Unless you bowl for New South Wales or open the pitching for the Yankees you are not going to be able to generate enough power with accuracy. Even if you do manage to hit it, unless the plane is very precariously held chances are you wont dislodge it, and you may damage the plane to boot.
In general the strategy that seems to work best is shaking the plane out, but obviously you can't shake it out using the trunk - you need to shake a branch (the branch the plane is in ideally) which means you need to get leverage on the branch.
The easiest way to do this is to get some lightweight nylon rope or string over the branch in question. Now - for how to do that there are a few tricks. If the branch is low enough (say up to five metres depending on your arm strength) you can tie the rop around a stick, or metal tool, or the like and try and throw it over the branch (this will be so much easier than trying to actually hit the model). If the plane is higher than that then some other techniques I've seen suggested include using a toy bow and arrow (with the rope tied to the arrow) and using a slingshot (with the rope tied to the projectile). Both of these will give you greater accuracy and power.
Once you get the rope on the right branch (make sure the rope is long enough to reach the ground twice yeah) then you can use it to shake the tree branch and try make the plane fall out.
Now - a couple of things to be careful off:
- Often planes are most damaged by the fall from the tree to the ground rather than the crash into the tree itself, so if possible get an assistant to do there best to catch the plane.
- With regard to the assistants safety, be aware that all this branch shaking might dislodge a branch, sticks etc. So be careful.
Here's hoping you don't need to know any of this!
Cheers,
Oz.

I once had a plane stuck up a tree near Seiffert Oval in Queanbeyan, i didnt know what i was going to do so i went to a shop for some inspiration.
I found some cheap rope like you described and a $2 hammer which works like a grappling hook.. did the trick!
Like the idea of using a toy bow for accuracy!
After getting my hammer stuck up a tree the other week i taped together a few lengths of poly pipe and poked it out, but its hard to carry a heap of poly pipe everywhere!
To recover our beloved electrafun we used no less than 40 metres of light rope with a number of larger sockets from a ratchet socket set tied in a bunch at one end. I had to experiment quite a bit to get the right mass of sockets to carry the rope with any accuracy and still be light enough to be within my ability to propel the whole mass to the required height....
I propel it with my arm !!!.. no slingshots or bows here nancy!
But here is the useful tip: If you are throwing a weighted rope up over a branch you will most likely have to try many times before throwing the rope over just the right area... with most of the failed throws the weight and rope will fall all the way over or under and back to ground level... but.. sometimes the weighted end of your rope is held up in the tree(in the same way your r/c plane is!).. Whatever you do, be very attentive and easy about the way you pull the rope back to retrieve the weighted end. If the weight is still swinging over a branch and you start pulling back in haste you may initiate a wrap around event that leaves your rope forever unusable by anyone but minute Tarzans.
With this rope over branch method it was an ugly business retrieving our electrafun from about 12/15 metres up in a gnarly old gum tree and the plane was damaged by the rope manipulation we had to use to free it.. and at the end of it we forgot to catch the plane when it finally fell to ground...
