Hi David,
The taycol motors were thought ok for a huntsman 30 years ago, but are now just lovely collectors items. As Paul says, reversing and speed controling wound field motors is tricky with todays esc,s and would need a wealth of experience. Also it wouldn’t normaly go very quickly, the only exceptions I know of were some experiments done long ago. Use a modern motor and esc, advice is best coming from your local club, or by chatting to a supplier such as Westbourne models, model motors direct, or a GOOD local model shop. ( some shops know cars and planes better than boats)
Happy new year, let us all know how you get on.
Charlie.
