Hi Paul and welcome to the Forums, I certainly hope we can be of help to you here as we have modellers of all levels and skills on here.
As for the Shackleton, that would certainly be an impressive model to see and will certainly be quite a project to undertake....Hopefully you already have some experience of R/C Models under your belt before attempting this one !!
There are not many 3 view drawings around for this one, even my favourite blueprint source does not have these (
www.suurland.com) However I found some some that may be of use to get working from to do your own plans.
They can be found on the link below:

The only other way I can think of to get around this is to get some Lancaster Plans and modify them to the outline of the Shackleton as the two planes resemble each very closely, so it should not take too much to work out.
I am sure you will get more replies yet.
Good Luck and Regards
Mark.
