OK Now the UP<G>I resorted to a regular iron but that still was not hot enough with the heat pad on it.
So I just used an old T shirt and that let enough heat go through and very slow, bit by bit I saw the wrinkles fade away.
All bubbles are gone and ditto for the very loose covering between the ribs.
The MoniKote is tight enough to play a song on now and the job would have come out better if I had the right tools.
Below is the one half of the wing that I thought would have to be recovered.
The leading edge from root to the tip was all loose and was fluttering when I put it in front of the fan.
PIC is the best I can do but look at the leading edge,
The MoniKote got sucked right into the balsa and I can see the grain of the wood.
Thanks for all the helpful tips and suggestions
