This will be my first balsa build for... er... 32 years. It's an old David Boddington plan that was uploaded to the Vintage & Old-Timer Plans thread at:
https://www.rcgroups.com/forums/show...265873&page=60 Looks like it was originally published in January 1965 in RCM&E.
The original was petrol powered with (I think) just single channel control on the rudder. I'll be doing electric power and 3 channels. I've already had to butcher the plan to add elevator control. There will be little integrity here.
I may be some time...
