the idle current of the avionics will eventually drain it flat, and flat LIPOS are permamently dead ones.

Right, I see. If you're going to continue with this 'crashing into tall objects' method of flying I'd employ some kind of battery saver.
I assume that these batteries are Expensive Sought-After Objects Whose Loss Is To Be Mourned.
Would it be possible to give the battery pack a little ejector seat and a parachute? Maybe stick it to the plane with hot-melt glue with a heating element through it, and remotely activate the heating element to soften the glue and releate the battery.
Obviously this isn't an answer to the immediate problem.

Oh, you mean like a little ejector seat and parachute for the battery?
David
Not possible. Anything inserted between the battery and the model is either heavy, of significant resistance, or both.
Its not a common occurrence, and wouldn't have happened this time but for an unusual confluence of a new model, an early morning test flight in a less than ideal location to avoid flying up sun, and a rather conservative setting on the ailerons and a rather agressive setting on the elevators.
In short I glanced down to find the elevator trim, and it must have done a stall and a roll off the top and ended up heading for the trees..
Well about 17 quid anyway.
No.
That's my food bill for a fortnight!

Oh! You mean pilot error?

A combination of pilot error and a new untried and untrimmed and fairly fast airframe. In this case its 'test pilot error'
Its pretty hard to launch with your right hand, and then rapidly get it back on the transmitter to get all the sticks moving in the right direction to control a plane that wants to loop..and turn left..all at once..
It's not as though anyone had ever built this plane before. Only me. These things happen.
Its still up there despite last nights winds, but I have a new airframe freshly laser cut, so if it hasn't fallen down by the time that is finished, I'll have to write the battery off and try and smash the rest out.

A fair number of those (including at least one 72m one) tend to be used at Silverstone for the GP each year. Scary scary looking things...but strangely fascinating to watch :)

Has fly by wire not entered the model industry yet?
I was working on that in the late 70's at British Aerospace. I would have thought that it had entered the development phase of model flying by this time.
Though I will contact a colleague who I used to work with, who now flies pure jet models, to find out where the hobby has got up to these days.

A radio controlled helicopter with a grappling iron on it?
I think it would have been dodgier if it was "use a small boy"
You should leave it up there as a warning to others.
Cat rescued from tree 13th March 2007
A CAT which spent almost four days stuck up a tree in Worcester has been rescued safe and well by firemen.

What about the flyfisherman? on second thoughts they only go for bluebottles.
