Introduction: Remote Control Knex Boat

a few years ago i made a knex boat which wasn't remote control so now i made it remote control. hope you like it.

Step 1: Bow

the bow (instructions on picture).or just look at it.

Step 2: Mid & Back Section

mid & stern section

Step 3: Attatching Bow and Smoke Stack

attaching bow and smoke stack(you don't have to do the smoke stack

Step 4: Motor Assembaly

the motor part. this is a bit hard but not that much. i forgot to do the other motor just use the steering motor and do the rest the same. it might go slower than normal but that is ok.

Step 5: Attaching the Motor to the Boat

attaching the motor to the boat

Step 6: Steering System

the steering system

Step 7: Extras/opptional

extras and optional

Step 8: Covering

the covering(making floatable ) part

 I am working on a mini knex submarine i got it to float but the paddles dont work well they move but it wont move the sub any tips? (i tried plastic wrap it comes off in the water)

Try to offset the paddles. turn one of your paddles so that viewed from the side it looks like a plus symbol. +

When it spins one way, the top is going forward and the bottom is going backwards. Problem?

Paddles only propel the boat when they're less than half submerged in the water & become inefficient at high speeds. Propellers would be the way to go. You can fiddle with the angle of the blades according to the speed of rotation and torque to achieve optimum efficiency.

i LOVE TNIS BOAT.......even if i modded it so that the bow became the stern, the bow(new bow)had a huge bit coming out of it, and agged useless sails-for looks, of course-also, i didnt have the bits to make it rc, and i dont understand the steering......then i broke this up. i have topics, i went from boats to guns to planes-and im stuck on planes....cant even make a glider/hangglider...:(

i see. yeah plains are difficult. the steering was kinda last minute/went as i go. you could have made a different version of the steering so that it would make sense.

i made a knex boat that actually floats and it uses a huge wheel thingy in the back to move it has motors but its not rc. i mad it si that it also has little submerged claws big enough to catch shells and stuff. its really cool but i dont know if i should post it.

author
Sun Gear (author)n1o22010-10-26

go ahead. i posted an instructables on how to make it RC. the claw seems really cool. see if you can make it so that you can actually harvest claims.

wouldn't it be easier to tape the whole thing, i mean tape IS waterproof.

so is tin-foil...

lol the pictures are so bad that i dub this the failboat! lol

author
Sun Gear (author)The Jamalam2009-01-27

GIR!!!!!!!! lol great show, great avatar...does this actually float? knex has atleast like 20 holes per snowflake, and real boaats float from compressed air in the hull, does this float??

Um...didn't you take Boats and BOUYANCY unit in grade 3?

author
The Jamalam (author)Zenosythe2009-01-27

did you take a spelling test in school? its buoyancy, not bouyancy

author
arrow shot (author)Zenosythe2008-09-28

unit? i dont have 'units' in my school. We kind of go from this to that and back to this in classes...and you are the first person i have ever met that takes a boats and buoyancy class... i never learned about buoyancy except for a small 5 minute class discussion when we get off topic.

author

The boat I had didn't have a compressed air hull, just 1/2 inch of fiberglass.

Sun Gear (author)arrow shot2008-02-13

also look at the last step

author
Sun Gear (author)arrow shot2008-02-13

wasn't sure if you knew this but boats float because its hull displaces more water than its own volume which would make it float

author
Sun Gear (author)arrow shot2008-02-13

thanks. yes it floats. i posted it as an instructable

ti looks pretty hard to do.

author
Sun Gear (author)Bugman92008-10-28

its actually pretty easy its kind of hardto how make it on instructables

robocrazy155 (author)2008-08-13

this is sweet! the rc function combined with the possibilities of knex is awesome, I was going to try something similar but the rc I had ran on NiCd batteries so no good...

depends on the time frame you mean. some boats today use both .....dang! i always forget words on insturctables...uh...i think it starts with an s...presigures? nah...frag it its on the tip of my tougne...lol ive been sitting here for 5 minutes thinkin...lemee go get a dictionary....omg i feel so awkward...tiemf or dictionary.com...!!!wasn't an s, its method! yea, some boats use both methods says my nerdy 4rth grade QandA book

i was board today and i was looking over some of my comments and eventually got to yours. and when i was reading this comment i just realized that the word you were looking for was strategies.

Sun Gear (author)arrow shot2008-02-14

huh cool i didn't know that (currently listening to queen)

I thought of an idea for improvement... You could have made a float by putting a bike innertube around the perimeter. Much more leak-proof than the foil!

author
Sun Gear (author)JerryMopar2008-05-05

and it has 2 layers of plastic the foil is just for looks

author
Sun Gear (author)JerryMopar2008-03-15

i could but i would have to buy one and the way i did it is much cheaper. but you could do that

author
Sun Gear (author)2008-03-15

i have modified the wheel design but its heavier but if you think i should post it on just tell me

author
knexguy (author)2008-02-13

Looks good, could do with better pictures though.

author
Sun Gear (author)knexguy2008-02-13

dang, thats pretty smart

author

thanks. the original plan for the remote control motor was to use it for a cabinet opener but it failed because the other door wouldn't open so i did this

nice. i made a remote control knex car.
