I am going to start a small hovercraft project run on motors and batteries , could anybody help me with the best , efficient design which is stable and the appropriate dimensions(it is a small one).

Thank you in advance

Search the forum. And then ask specific questions Do you already have the parts on hand?

Hi , I have an idea why not buy this hovercraft - http://rcbazaar.com/products/1419-hover-craft.aspx and then change the motor and ,  a servo , receiver and battery

Because I dont think that anyone can make a DIY hovercraft in their first time only , first try this and then think about making one , because for that you will have to design frame , import rubber mat ( I have never seen it in India ) , you will need another motor to lift the hovercraft and thus another battery also .

well if u go for a ready unit like Devang Sir has mentioned, U ll atleast come to know how it works, n what are its important parts. Now u can disassemble the craft n thoroughly observe it then it ll be pretty easier for U to start your own project.

Devang seach on the forum , there are some great hovercrafts build, and that too in their first attempt. Some names i remember are Mr swapnil, Vc sir and many more.

Or you can first try your hand at making an airboat first. Then you can move the electronics over to a hovercraft.

yes i have all the components required for that...!

working on hovercraft, using the circuit of cheap chinese remote car, how can i connect the ESC to it, as one wire is the signal wire.

Provide some more details..

simple two channel circuit
channel 1: acceleration brushed dc motor
channel 2:steering brushed dc motor

i want to use brush-less 1400kv motor using this circuit.
so how to connect to connect it. Any suggestion?

What is amperage of ESC?

5Amp to 7Amp

basically I'm thinking to use 20a Simmons ESC but having confusion how to connect it

Circuit board in your car is working as a receiver and ESC .

see you can only use brushed motor in toy grade stuff.

You can connect ESC battery plugs into motor output of circuit board .

But you have to measure , how much current is drawn by your existing brushed motor . Also what about controlling BL motor speed?

hmm but what about the signal wire on the ESC. do i have to connect it with the antenna of the circuit??

No , not for antenna..

then how can i access the BL motor using the RC control?

I dont think you can.

I think BEC wire can be left as it is . As Car circuit board is having both ESC and receiver .

Although i never tried all this and it may be risky ..
It may fry your circuit board etc.

this is the circuit type i'm trying to connect with ESC

you can used brushed motors.
