Its ok, I'm on a nostalgia 'trip'.
Many years ago, back in the mid 60's / early 70's, i remember long afternoons sat at Bournville Lake watching the RC Power boats after my Father and i had finished sailing the yachts.
The 'IN' thing in RC (IC) power boats at the time was a 'flattie' by SHG... almost an oblong (on plan) with the corners rounded out. I think they were Glass..
Anyone understand what i am talking about?... have pics?... drawings?... or maybe a hull gathering dust in the back of the workshop / shed / garage?...
