Hi Gerwin,

nice to see you again. How are your bikes working, any chance to get you working on another boat?

regards,
Manuel

Christian, was its das?
What is it?

[Chrisg81983]

Kent I think a pump of some kind Maybe for constant cooling

[nata2run]

Maybe it's a coffee machine hehe, what else could this boat need?

[Gerwin Brommer]

pickups for watercooling ?

@ Manuel :

Nope, no more rc-boats for me. The only boat I would consider working on, would be 1:1 wooden raceboat ( Google for Flyer 15 hydro )

If it is his turbine it is the pickup for the transmission cooling. He has obviously opted for a constant pump instead of the traditional forced system.

hmm, the "picture filename" does say HPR_135 but he posted in this thread......I still think its a filter system for the coffee machine LOL, you watch! next there will be a nice chrome polished tab :)

Hello Guys,

Christian tried to upload the pictures in usual size but seemed to have some troubles with it. Next time I give him a visit, I'll explain it to him. For today I'll continue the thread here.

What Christian wants to show here is what some already thought, additional cooling for the gearboxes/transmission. So far both gearboxes got their cooling water from a single intake in the rudder blade and a Y-connector. First step was to make new intakes in the last step of the boat close to the tunnel. These pictures should be pretty self-explaining.

Next task was to create mounts for the pumps. These are rated at 12V and will be powered by a 3S lipo. They really create a huge waterflow and also some serious pressure. Completely made in germany with fibre reinforced casings and rubber bushings - makes them very silent!
It wouldn't be Christian if the parts were not completely custom made (cut, filed and sanded) out of glossy CF sheet:

As I already wrote, both pumps will be powered by a single 3S Lipo with 2800mAh, lasts easily long enough. The switch he installed inbetween is a magnetic switch from the german manufacturer Emcotec. On the outside you just need a little bore for the status LED, the pumps are shut on or off simply by holding the magnet either on the left or on the right side of the status LED. It works up to a distance of 1/4" so way more than a hulls thickness.

But also the battery itself needed a kind of mount, he decided to place it within the hatch and created a mount very similar in terms of optic to his RC box. Its made out of texalium and CF sheet, with aluminium spacers and anodized screws. I could go into details step by step how it was done but I think also this time pictures should be quite self-explaining.

The sheet on the left is glued to the inside of the hatch, the rest of the mount can be disassembled.

Here you can see in the middle the status LED of the Emcotec switch, he turned a little aluminium spacer for it which he polished before he installed it:


Next step was to make it a little nicer with another skull:

The black foam was just because he was waiting for some 0.3mm CF sheet but as soon as he got it he replaced the black foam:






So that was it for today, we hope you enjoy!
