I recently moved to Guildford which has a dedicated (if small) model boat lake.  I since remembered that my grandfather once built a model boat and I would like to restore it for radio control use.
 
I have learnt on another forum that the boat is an Adamcraft Seaplane Tender and is probably quite rare. In the days before affordable radio control gear, my grandfather powered this via a windscreen wiper motor connected to alkaline batteries, and simply ‘set’ the rudder so the boat would run in a large circle until the batteries ran out or the boat was retrieved and the motor switched off.
 
The original motor and batteries have long since been removed but the rest of the craft is in excellent condition.  I would like to equip it with a new motor, batteries and radio control gear (including steering).  I am looking for advice on how to go about this, what parts to buy, and what might be a realistic budget to work with.  I don’t think the boat will get regular use and I’m not looking for something to race, or of ‘enthusiast’ grade – just enough to get it up and running, and not gathering dust in the loft!  There’s a lot of room inside the hull, so I could probably be quite flexible with the fitting arrangements.
