The HobbyKing Swamp Dawg Air Boat comes just about ready to run, Only a few minutes of assembly time are required to have this fun RC model skimming the surface of your back yard pool or local pond.
The Swamp Dawg features a full plastic platform that is foam filled making the Swamp Dawg virtually unsinkable. A CF and Alu motor mount, 2300kv Brushless motor, 5.5in propeller and a 9 gram servo have been included.
You will require a 20amp ESC, 1000mAh 2S 7.4v Lipoly battery and your own Tansmitter and receiver (Tx/Rx) to complete this model.
Spec. Length: 479.5mm Width: 188.5mm Height: 196mm Propeller size: 5.5in (Included) Total weight: 625g -635g Motor: 2300kv Brushless Outrunner (Included) Servo: 1 x 9g (Included) ESC: 20A (Required) Battery Compartment Size: 70mm x 40mm x 20mm
No they do not need watercooling with the recommended ESCs. A big BUT: At least one of these recommended ESCs (the Fixed Wing Brushless I originally bought) has no reverse! This is IMHO crucial for a rescue boat, I bought it for that purpose myself. I ended up using an old, waterproofed aka plastidipped 45Amps turnigy Car ESC with the vent outside the black socket and 2x1800mAh 2s Spare Lipos in series on the deck - so 4s in theory but 3s in practice since this ESC only supports 2-3cells. Went up from ~7130 to 11200 RPMs that way, measured with a tachometer. The ESC gets pretty hot so just put some old computer IC/CPU coolers in front and back of the ESC, works flawlessly. Anyway goal achieved, I can use my car RC, it has reverse and is much faster/more powerful using old spare parts.
Here is a better view on what these boats drive like! Quite enjoyable actually. Especially for it's price!

I like this boat with 3C nano tech 850 Lipo, goes fast. Be carefull if there are waves in the water, mine ended up side down. Bad day, I got it from the water and flip it back over and got water in the speed controller, it smoke. Got a new one and order new reciever coming from Hobby King. If it happens again, I think I would keep it upside down, and un plug the speed contoller, then let it dry over nite too save the electronics. Darren from WI USA...........................

Great with 3c 850 nano tech, If it ends up upside down, leave it that way and unplug it. That way water will not go in speed controller and burn it up. Darren from WI USA

Good value for the money.The only problem is the motor mount hole is too small i will have to have it drilled out so it will fit the motor.
This is how I re arranged the electrics on my Swamp Dawg. As it's almost impossible to post pictures on HK Review pages, I'll have to try to explain it to you. The 1800mAh battery is turned on its edge and placed in the well in front of the black box. To hold it in place I have velcro'd it (underneath the battery and also to the front of the black box). The connection to the ESC is taken through a small hole that I drilled in the side of the black box. To enable easy access to the servo and receiver, I have made up a short battery lead that has 4mm gold sockets with housing on each end, and that lead is what goes through the hole in the black box. One end goes to the ESC (which is velcro'd to the underside of the black floor inside the black box), ... are you still with me, nearly finished now. The 2.4Ghz HK receiver is also velcro'd to the underside of the box floor. This allows plenty of space on the top side for the wiring and movement of the servo arm. While I'm here, you should also seal the screw holes on top of the deck ... or they'll let in water! Hope that all helps. Cheers.
