Police Hydrofoil build

[Diegoboy]

I guess Doby doesn't like my new clothes pin?

LED's are now in hand, Resistors have been picked up, I just need to work out the housing for the navigation lights...

Shall I go with this style?


or this type?


or even this set?


Whichever I go with, the bulb will have to go to make way for the LED's

Any thoughts?

[HydroMike]

this is really nice ur going to have to bring this to our next d12 race next year have to see this in person

[Doby]

I like the new clothes pin!!

[Diegoboy]

80% done with the LED's. I will post a Lights video when done

[egneg]

Can't wait to see it run Danny.

[Diegoboy]

Same here Chuck! I hope you'll be there for her first run.

Video as promised:

Chatter sound is from the cheap servo I attached to the RX. Spotlight isn't ready, and the LED used as the spotlight in this video isn't even the one I will use, It's just there for testing.

[Boaterguy]

that's so cool!
would using a headlight lamp work for the spotlight? it sure would be bright enough.

[Diegoboy]

I have a very high power LED with the proper limiting resistor all ready to use, but I need a spotlight housing to install the LED in. I used to have about three or four of them but now I can't find one.
It looks like this, but I remove the bulb to install my LED...

Looks really good. As I said before. You sure have an eye for detail.

Okay, I need some input here. I know most aren't scale boat guys, but this is a mostly FE question.
She will be brushless, but I will not be able to cool anything with water (since she rises out of the water) I'm looking for a mild brushless setup that's better performance than a Graupner speed 600 race brushed motor (21,000 rpm) but it needs to be mild enough to not heat so much it needs coolingon on 3S lipo.

I do have a pair of motor heat sinks for a 36mm dia motor:



Prop might be around the 32-38mm range.

What I have to work with:
Turnigy B36-56-1800kv
SV27 45A ESC
Pro Boat 45A ESC

I know I will need either another motor to use either ESC, or a new ESC to use this motor but What do you guys think?

[Doby]

Why can't you watercool? Can you not run tubing down to the foils and have a pick up there??

[Diegoboy]

The rear wings have the more vertical wing arms, they already have tubes mointed in fromt of each arm for the rudder shafts. The front wing arms are out at an angle which would put any pickup at the base of these arms out of the water during "flight"

[Diegoboy]

my only real option is to use a prop wash pickup that follows the stuffing tube to the prop, but I hate the look of them on FE, there's NO WAY i'm doing it on this one.

[Diegoboy]

What do you think about a SV27 motor on the Pro boat 45A ESC I already have on 3S? Still too much heat with heat sinks on the motor?

[Rumdog]

Castle makes some nifty fan cooled heat sinks for the 40mm motors. They may have them for 36mm cans too, but not sure.
