If Lisa Curry -Kenny and Rambo shed a tear over a 5 minute video then you need to watch it. This hits home like nothing else.

GoPro Camera Customizations

Monday, June 09, 2008 / Posted by Rambo / comments (4)

I've been a busy boy these last couple of weeks modifying and customizing a batch of GoPro Cameras incorporation wireless remote control and 2 types of delay timers in preparation for filming the Hamilton Island Cup. As i will also be paddling in all the events, i need to be able to have most of the Canoe Mounted Cams turn on and record at different parts of the course automatically, except the radio control type which will be controlled from the support boat.

This is what i have so far.
Have now finished and on water tested all three modified versions.

The first picture is obviously the remote control version. The transmitter has a range of 1km LOS and the four buttons have the following functions.

A - Powers Up/Down the GoPro and steps through menu.

B - Record On/Off and sets menu choices.

C & D do the same as A & B but on a different channel, that way I can control 2 GoPros independently or as many Cams as I want on each channel from just the 1 transmitter.

The second picture is the delay timers Type 1 and 2.

Type 1 will turn on the GoPro and activate record 5 seconds later.

Type 2 will turn on record only but it has AA Batteries in the box instead of AAA so will last 5 hours plus.

Both can be delay set from 1 min and up to 5 hours.

All totally waterproof and can take some rugged treatment.

There are 6 R/C type and 3 each of the delay timer Types.

Also some new mounts

Suction cup Mount

Velcro Mount

Manu Mount (front or rear of OC6 Mirage Outrigger canoe)

Roll on Hamo …. Haahaaa.

Leg Drive in an OC1

Sunday, June 01, 2008 / Posted by Rambo / comments (2)

Leg drive is really not what actually happens in an OC1. Yes legs do appear to pump, as in the Paradise video, but that is to allow the hips to rotate to gain further reach. Unlike the Surf Ski/ Kayak stroke which sweeps out to the side and tilts the ski/kayak from side to side, the Oc stroke is straight down the center-line of the hull. The legs are just a part of the connection that starts from heel, continues to circle the body and ends at the blade anchored in the water. The legs pump in response to the twisting of the hips.

Some OC paddlers appear not to pump at all, this i believe is fine as mostly they are larger body types and the torque transfer is primarily through their butt on the seat connection.

Lot’s of top paddlers paddle with their butt very close too their feet, which gives them the high knee look, so obviously there is not a lot of leg drive going on there, just a different style of torque transfer and it works for them. Personally, i cannot paddle this way as I’m too unstable and my learnt style requires that i have hip rotation.

No matter what style you adapt, the most important thing is still getting efficient transfer of power from the paddle to the hull resulting in maximum FORWARD movement.

Chuck in a few bumps, side current and wind and you have a whole new ball game.

A Case Study - Danny Ching on OC1 compared to a Kayaker

In this video of Danny Ching, his leg drive appears to be restricted in an OC1 compared to a kayak. As you can see from this short video of him … there is slight leg movement but no leg drive that i can see, that is not to say that he could be pushing on the heel to lock the knee

Also i have split the screen with a cut a way kayak showing what leg drive is, you can clearly see the difference in foot to butt level, which then allows more rotation.
