Hello.
I have listed some books on ebay - hope it's OK to put them on here.
First there is a first edition copy of Gordon Whitehead's 'Radio Control Scale Aircraft........'
**LINK**
Then a 1985 copy of David Boddington's ' Building and Flying Radio Controlled Model Aircraft' - cover creased but very readable.
**LINK**
And finally a copy of '104 Easy Transuistor Projects You Can Build' by Robert M. Brown (1973.)
**LINK**
I hope they will be of interest and use to someone.
Thanks.
