Radio Controlled Boats |

it’s band new it has a .15 engine on it Dolphin Nitro RC Hydro Sport Boat i can’t get it to start the carb must be all messed up or maybe the gas is wrong or the glow plug i don’t know but it did start for like 3 sec then never after that.

Check your glow plug, even if it’s new they burn out real easy. If the plug is OK, try a light spray of ether in the carb as you try to start it. If it then runs, the problem is a fuel line or maybe a fuel line shut off valve that is not opened or the air vent is closed in the fuel system.

I am allowed to get any RC Vehicle I want just not the gas powered ones.. only the battery pack powered ones. what should I get?

Car
Truck
Helicopter
Airplane
boat
ect.

and what ever you say tell me why they are fun and where you drive them.
and if you say airplane dont just say AIR. be more pacific.

I personally think helicopter……… the air pressure ones are the best- Air hogs is a good seller! They go straight up in non windy conditions-
but to be safe try a three quarter acre field..

They are really fun!

Good luck

hi i need help , i have a nitro hammer rc boat and i read all the directions and the directions are not clear. how would i shut the motor off. i want to run it today but i dont no how to shut the motor off once i get it running. the directions said to hit the triggle on the controlling foward to cut gas of to the carbs.?????? helpp plss

Hello, welcome to the nitro hobby! To shut off the engine, you can pinch the fuel line. I have never had a nitro boat but I have dealt with nitro engines. On nitro RC cars you can also put your foot on the flywheel, I don't know if you can do this on a boat. You can put your finger over the carb. Pinching the fuel line will over lean the engine and stopping airflow will flood the engine.

As for the directions, it may mean to give it less gas until the engine will shut off due to a lack of fuel.

Any further questions feel free to email/IM me. I will be glad to help.

or does anyone know of a gas or nitro one for under 100 bucks i really want a fast boat. i just bought one for 25 dollars that is so slow its about 2 mph even though it says ten please help me find a fast one

This is a must see…
You have got to see this… as you simply won't believe it…
They are made of styrofoam which is coated with boat epoxy and then painted…
They are $79.00 at your local hobby shop…

Happy & Safe Boating!

i am highly into modifying electric rc boats. i am also into gas models too…

lets build lots of things together

I searched online. Not too many good tutorials. Please provide me some tips which are basic for an electric or gas RC boat.

Most people would say hydroplanes are the best hull to use for boating. Plastic hulls are something you will want to avoid mainly for electric because they are so heavy and require alot of torque to get on the plane of the water.

Fiber glass and balsa coated fiberglass are the way to go.

Electric boats work great with direct drive system as is maximizes the speed and reduceds the amount of wasted enegery in a geared system. Putting whats refered to as a stuffing tube can be very rewarding as it will maximize the potential of the motor.

Alot of people will argue that using 3 vs. 2 finned propellers make a difference, but more important is the angle of the prop and drive shaft. Those two will make more difference in your boat that most all others combined.

Before deciding prop and drive shaft placement and angles, you need to know your cog or "centre of gravity". With gas or electric boats you want your hardware to be best layed out so that the cog is nearly perfect, (slightly aft is good). If you dont have a boat that has a good cog then it won't get on the plane of the water very well making it slow and hard to control.

Water cooling is extremely important be it electric or gas. A good idea with boats is to create what i'd call a "thermostat" for the cooling system. Just like in a car you don't want the water going through the system so fast that it doesn't have a chance to remove heat. What I've done is take a small piece of the 5/32 brass tubing and a small piece of 1/8" tubing and ca the smaller tube inside the larger one. I cut the exit fuel tubing about half way down it's length and install the little thermostat in. Restricting the water flow this way gives the water a bit more time in the system to remove heat. This seems to work pretty well in most boating applications.

A good idea is to waterproof your electronics, there is a sray on rubber you can purchase that will literally waterproof servo's bec's, receivers etc. Many would use a compartment but I like to lose as much weight as possible for max speed.

Consider size of boat for the motor you want to use, or vise versa.

26-35" I'd use a .12 gas or 380-540 elec.
32-36" I'd use a .15 gas or 600 elec.
37-42" I'd use a .18 gas or 750 or motor that likes more than 80 amps

Last thing I can think of is Make sure theres no water leaks!! I use CA glue cauking or even hot glue gun. Anything that gets the job done as long as theres no leaks. Even if your electronics are waterproofed water in the boat will effect it's performance.

cheapest gas RC boat is the Smartech daulphin tunnel hull but it is a piece of garbage.

Traxxas Nitro Vee is a great boat and doesn't break the bank.

Cen nitro thunder is also a great boat for less money.

Both are around the same size and use .15 engine's. I like traxxas electronics better but then I like cen's hull and engine better so it's a toss up.

cheers
