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
If i were 2 set this up with a HK-300 n HKR3000, would it be possible to have reverse function? What ESC is needed? N is the stock motor suitable?
Also how do i totally waterproof this boat so that in the unfortunate event of it being upturned i can still gently coax it back 2 shore without having to dive in? Because where i am from entering any body of water, like reservoirs, ponds, etc. will get you arrested. N really wouldn't wana spend a night in jail to rescue a boat.
Well somewhere below this discussion i think i saw a video of someone flipping his modded swamp boat n was still able to coax it slowly back to shore totally inverted underwater. So perhaps anyboday can enlighten me on how he did it? Thanks
another tip you can do is like the Skipper aircraft HK sells . They put at the factory silicone on the ESC to keep it from getting wet. They blob silicone on both ends so no water can get in. Or a balloon over the ESC like they do with the Coota aircraft
There are vids out there of this little air boat flipping . I am tempted to buy it and use it to get flipped water aircraft back to the shore. Hope it works out for you
I've been fpving mine and flipped it, once i got back in range( around 1k down river)i could get it back to the bank needed to not give it much throttle as the motor would stop but little throttle got it back and controls were inverted,best to unplug the lipo underwater to save esc ,i had waterproofed with corrsionx and liquid tape and everything still works*) was in the river thames*) any car esc with reverse should work i've got a trackstar 25a to try next time out.
i put corrosionx on the esc and rx and liquid tape on the vtx and camera no need for anything on the motor.
With the corrosionx i dipped the stuff in then let it drip dry after taking it apart, can be a bit messy as it is an oil but does work well,even used it on a kk board on a quad a flew in the rain.
With the liquid tape i put a couple of thin coats need to make sure of total coverage could use this for everything as it is much cleaner once dryed just make sure there's no gaps.
as I posted above yours silicone and a balloon are used on 2 water aircraft from HK. It works very well BUT just cover both ends not over the plastic it is wrapped in or it would get no cooling. As for a water cooled ESC I feel it is more than you need. The motor as well needs to get air or will overheat

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.
