Hello - and thanks for the welcome,
I began modelling with card and paper in the early seventies - at school...
A development of those modelling activities led - with the encouragemant of an uncle - to my subequent obsession for building anything that can be radio controlled... EXCEPT helicopters !
They and I do not get on...!
I have in the last few years become less able to get about, due to a back problem - so the R/C model aeroplanes have taken a back seat to R/C Tamiya vehicles - and a resumation of the 'card modelling' that started it all...
I have lots of reference material.
Books and .pdf's about aircraft in the main ( including some
helicopters ! ) - though I have also a few about warships and military vehicles.
If you cannot find anything about a particular subject by first searching online - feel free to ask me if I have something that will help...
