Speedfreak Gen2 Hydro Build

VERY nice John.
You going to come out and run with us this summer?

I'm trying to get there Mark! I need two CF battery trays and 1 plate of CF to make the ESC mount. The twin Fightercat #071 just needs a coat or two of Urethane :)

Boats looking good. My batteries went down the center and into the nose. The motor was mounted right behind the batteries. Everything gets mounted so you can get the cg 1 to 1.5" behind the sponson. You can probably get away with a more aggressive prop like a 560 or bigger since this is a hydro.

Thanks for your reply MarkF :) I was hoping you would chime in on this one! I used a rolled cardboard carton to balance her on and I think I'm pretty close to that. I finished the steering linkage. Trying to decide if wooden battery mounts are strong enough or should I get carbon fiber mounts. I also want to put the ESC over the motor on a CF plate and screw it into the stuffing tube mount and Velcro it with 2" wide strips. More pictures to come

So quit typin' and keep buildin' I want to see this baby run!

Just a few pics;

Installed the rubber boot on the extruded piece of CF tubing used for the rod.

I used milled fiberglass added to the epoxy and bonded the CF plate to the bottom of the hull and to the rail.
I used CF tubing for a ridged path for the steering rod.

Close up view of CF servo mount. I used a 3x4 piece of CF/K cloth, laid it down with the servo mount on top of it,
and poured the 2 part epoxy around it. It helped fill any gaps between the mount against the bottom of the hull.

So is there an oiler on there John? I've been hanging with some gas guys and that is what they run.

Move the shaft saver up next to the collet after you tighten the collet to keep the unbalanced shaft saver from whipping the cable in the tube.

John I sent you a PM about the cell pro chargers.

Thanks for the tip!

Thanks Ray. Good deal!

Yes there is slash There is an opening to add oil but I may use it to apply grease instead. I have a small grease gun I use for my air powered tools at work that fits the hole perfect. I just need a way to work the grease down the tube instead of up

[jcald2000]

Turn the prop by hand or with a drill in the correct direction, the strands act like a screw and will pull the grease toward the prop.

More pic's;

I've been trying to place the ESC in a accessible position and also add a little weight to the back end due to the large batteries, so I came up with a CF plate and mount it using the stuffing tube mount and the motor mount. I'm going to mount it using velcro straps and 2 inch wide velcro strip.
