YPC....
Here are the spec's for the components used in the InDaTube II build:
6S NanoTech LiPo-5000 mAh-25-50C discharge / 120amp ESC w/dual water inlets / Leopard 3674 / 1400kv / Airtronics Digital High Speed Servo / Airtronics MT-4 with RX-462 Telemetry receiver.
Running gear is a .150 Flex Cable with 3/16 prop shaft, full length brass stuffing tube, replaceable brass bearing and a teflon liner. I use two different props, depending on the size of the waves. Both are CNC Aluminum 3/16" shaft, sized at 38mm and 40mm. I do have a 42mm prop that could be used to "Tow-In" MJ and Resinator when the Big Wednesday South Swell comes to the Meat Grinder here in San Clemente!!!!!!
