Well, I tried to take my 10' Slayer propel and camera out this past weekend on the Minnesota river (first time I've taken the slayer on the river), and got my butt kicked. The current was way to fast. Although it moved decently upstream, I had to constantly be course correcting as the current would move the rudder if my hand wasn't on it. Lesson learned.
I mainly wanted to go out and see if I could figure out a good spot for the camera that is easily accessible while in transit. I had tried to figure out a tripod setup in the garage, but no luck. The best I could come up with is to place a towel in front of the seat and set the camera on it while moving.
I've ordered a 1/4" female x 3/8" male 50mm bushing adapter that I can then mount my Manfrotto tripod head to on top of the propel drive where the 1/4" hole is located. I've measured it out and my feet will clear it. I mainly hand hold may camer setup and don;t really plan on using the mount to shoot from, but I suppose it is possible.
I do have a concern about the weight. That would put about 6 lbs on top of the propel drive. Does anyone see an issue with that much weight up there? It seems to be well built and I would think that is a low stress area. An other ideas for mounting a big camera and lens up off the bottom of the 10' Slayer Propel?
