MICRO RC HOVERCRAFT.....maybe

-=CrAnSwIcK=- · #1 02-09-2004, 01:18 PM

Hey, i know this is mostly little cars and trucks and stuff, but it's tinyrc.com, and i'm workin on a tiny rc hovercraft...right now, i'm just working on a prototype, and haven't decided how i'm gonna build the steering, i plan to use a clone PCB, and make it a working micro rc hovercraft...It was something i told this girl in my engineering class i was gonna make as a joke, then i got bored today and tried it...lol...Anyway, i just hooked up the motor today, and hooked it up to a small battery....IT HOVERS!!! lol, if you have any suggestions of how to do the steering, or what to use for a skirt...email @ garrettl@rogers.com...wish me luck, or try it yourself....

i dont think it of the subject when you have made it from a micro rc anyway i have looked at your picture and i thought there is another way of making them and to have steering and it is possible.

I will post pictures of one that i have ( not remote controlled just the frame).

I might have ago at this if you dont mind

Thanks martin

here is the last one, not for long

Normal hovercraft setups have one motor source to fill the skirt, and another source to propel the craft forward. Then a deflector is positioned in the propulsion air flow and is used to direct the craft.

You will need one channel to turn on/off the hover air. Another channel to propel the craft or have it simply hover, and another channel to steer. The bit steering assembly could easily be modified with a deflector and placed in front of the fan.

If you wanted to stick with just two channels, then you will have to wire both hover and propulsion motors to the same channel, which means that if you are hovering, you are moving forward and it you won't be able to move in reverse either.

For the skirt, try some plastic sheeting cut from a bag and trim it to fit.

Sounds like an intesive custom job, but it would be very cool to see working. And it would be able to work over carpeting where most bits wont. Would also work for water if you are daring enough!

thanks for the info

sweeeeeet! Thats a really cool idea. Can't wait for more pics.

Ok...this is what i got now...it's not much, but oh well...ok it hovers and moves with an on-board battery...i'm hoping the weight of the PCB won't be and issue, once i add a skirt...cause i'm pretty sure, that'll give it enough lift...i hope anyway...skirt, PCB and steering, still to come...

the total length is 2 3/4 inches....remember still a prototype, input as well as (constructive)critisism is welcome....got any ideas?? i'd like to hear em...my email again is garrettl@rogers.com

thats coming along very nice, with what i have (see pictures) it is to big so i will cut it down abit and put the motor/s on. what batts are you going to use?

Pretty trick so far!

I'd thought about making one using something like a Pringles can lid for chassis and a rubber balloon for the skirt.

Why don't you install a small switch (cut down DIP switch, or like a jumper) that you use to turn on/off the hover motor? You'll either want to be floating or parked, and I doubt you'd want to leave it alone long to run down the batts anyway. That way it leaves you with both channels free.

Then if you install Dual rear fans, you can use a differential-thrust for steering. If you pick up one of the Tank clones, you wouldn't even have to think too hard about forward/rev for one side. It'll drive like a tank, so you might want to install a variable resistor to tune the motors to the same output.

Otherwise, you could use 1 fan for propulsion, and a modified stock steering assembly to move a rudder. It will let you use 1 channel for power, and one for steering; just like a Bit. Rather than a tank, it'll drive like an Air-boat.

Excellent!!!

Think it'll be able to go over water?
