Hi everyone.
Many thanks to CJ for the information, and John for his help, sorry for the delay in replying but hospital and lungs got in the way.
I now have the plans 'The Fairmile B Class motor launch'. and have the info CJ gave me, and now I have more questions than answers. But firstly in reply to Ken. scale will be 1.48 (my brain can cope with this) must be built to R/C standard (There is a pub on the beach near the pond). I will have to ask the forum regarding electric motors, as I do not have a clue what is suitable yet.
The plans have a frame body plan. - I can see the external shape of the frames, but how do you work out the measurement for the slot for the keel, and also the frame profile. Also I can see the external keel drawing but how do you work out the internal profile ie profile for the frames to fit. John said he used double diagonal planking for his model, again where can I find the info regarding the thickness of the planks.
Sorry this is so long winded, but I can see this is going to take time.
Many thanks for all your time and help
Best regards
Tim
