The Shadow by Shg is one of those boats that in the 70's and 80's was a very pretty boat and powered by the recommended 21ci size i/c motor was a good mover. It was a boat i had wanted from an early age due to seeing the adverts in model boats magazine but being a mere slip of a lad was unable to afford.
Then about 3 years ago i went to a boot fair near where i lived and there on a general junk stall was a shadow complete with os21. I can only assume the gentleman on the stall had little idea what it was as he let me have it for a fiver. Value in anyones book.
I have since removed the i/c engine and replaced it with a rather small but high kv brushless motor with speed controller and i tine 7.4v 2200mah lipo. This boat has a suprisingly impressive turn of speed with enough torque to lean the boat over at speed. Probably due to it's unknown past it is quite tatty but i prefer to leave it original and it is now an unusual sight in the model boating population.
