If you look at a plane that spent a winter or long wet period of time, motor, esc, battery and receiver is a good chunk of change.(+$100)
So I found a method that is light weight, takes apart, and can reach a height of 56 ft. It even allows you to push on the fuse to remove the plane and save putting holes thru the wing.(Ask me how I know). I ended up paying only $25 where the LHS wanted to get rid of these extensions when change of winter season. They were extensions for pulling down snow off roofs.
Each aluminum pole is 5 ft(put together) and joins by putting one segment under the next and is locked in by the hole in one pipe and button snap in another. So put two together, reach down on ground and pick another up and attach,
guide the three thru the Y's of the tree limb or on tree branches and keep adding lengths, like a pool stick, your can line up to free your plane to push outwards until it drops.
You may have to reposition your pole(unlatch, drop section, etc) and start over. It is a one person unless you climb up part of the tree and with someone helping, you assemble say 2 half's and join them to remove you plane. Best I did was about 80 ft off the ground.
Again, the poles don't bend, alum is lite and the tree's y limb will give you accuracy to untangle and push it outwards to slide down.
Mention that to Josh, maybe he can find something similar.
