Hello its phill from Tassie here I think ive worked out the photo thing so here is a photo of my old girl MERSEY , she's 16 years old 520mm long powered by a .25 540 and a 5 cell 6 volt nimh pack which give about an hour an a half run time.
This photo was taken one afternoon when the powerboat boys with their 26cc speedboats (3 second wonders) were out for a play.
It was a great afternoon, they would send a boat out , it would promptly stop about 40 metres out , and Mersey would retreive them , frustrating for the owner but I was in my element.
