quite a few places sell them it was a xmas pressie two years ago, and I have a gps expander, lcd screen, rev counter, they are all quite cheap plug ins, it is invaluable to me, I love tinkering with set ups, the Huntsman runs a belt drive gearbox, I can change the ratio depending what size lake I am on, big lake, slow acceleration, high top speed, small lake, quick acceleration top speed does not matter, that and changing props can be diagnosed on a pc with the data logger.

LCD screen can be seen in the tic tac box, the two black boxes at the bottom are lipo cell alarm/monitors. Mine came from a uk supplier called allendale electronics, but they can be found on ebay

Brilliant video and great sound track. 👍
Where did you get the Eagle tree data logger, please?
