WHAT'S A TRICOPTER?

It’s an aircraft similar to a helicopter except it has three rotor disks. The beauty of the design is that three ordinary outrunners direct driving ordinary propellers can be used. Four helicopter gyros makes the tricopter super stable. And to make it yaw a servo tilts the back motor.

Step 6: YAW MECHANISM

FOLLOW THE PICTURES...

Step 7: FPV

Have you ever want to do FPV or OSD for cheap and have an old android phone and a WiFi modem (do not need any internet provider) lying around, it would be useful! 

STEP 1: Download this application called wififpv on the android phone LINK:  https://play.google.com/store/apps/details?id=com.macaca.wififpv&hl=en



STEP 2: Use any a123 battery to supply the voltage for the modem!



STEP 4: Connect the android phone running WiFiFPV to a WiFi router, and mount it onto a RC model.



STEP 5: Use your laptop to the following ip address shown on the android device OR use another android device to view as a monitor LINK: https://play.google.com/store/apps/details?id=com.macaca.fpviewer&hl=en


STEP 6: Enjoy your fpv and OSD!


OR IF YOU CAN AFFORD A FATSHARK THEN THERE IS NOTHING LIKE IT!!

THIS IS A VIDEO OF ME FLYING IT !





THE AERIAL VIEW







-------------------------------------------------HOPE THIS INSTRUCTABLE HELPED :)----------------------------------------------

<p>This is a great build. Thanks for the instructable. I am hoping to build one completely from scratch like this soon. I recently built a simplecopter frame kit which was a nice middle ground between a kit and DIY. Here is a video: https://youtu.be/-OofUOlSUK0</p>
That should be fairly easy, go for it! <br>Nice flying by the way!
Hi<br>I want to make tricopter by gyro's but i didnt know any things about how can i setup them <br>Can any body help me ?
Hey!<br><br>A KK2 board from Hobbyking is the way to go it has got all the gyros and accelerometers you need integrated. <br>Just go through David's settings and it should be ready to fly. <br>Here is the link to the video:<br>https://youtu.be/UZ4AaI6KPhA <br><br>
<p>is a 5ch tx rx ok?? </p>
<p>Hey!</p><p>A 5ch tx rx should do the job just fine if you are going to use one of the cheaper flight controllers like the naze32 or the kk2 for autolevel! But if you can afford a turnigy 9x go for it as you can grow your hobby with it! </p>
<p>could u plz tell me how much cost does it take to buy all parts of tricopter</p><p>???</p>
<p>Please read the comments below your question should be answered there. </p><p>Thanks! </p>
Hi i wanted to know if you can send me what kind of programming software did you use to program the tricopter. Can you also please send me the codes of the programming to my email: Leonardreyes6@gmail.com<br><br>Thank you,<br>Leonard Reyes
<p>Hey VERTEX13,</p><p>Now days you dont need codes to program the FC. Search it up on google there are tons of videos on youtube!</p><p>Regards, </p><p>Pawan Vijayanagar. </p>
<p>Very very impressive</p>
<p>could you please explanatory on how you made yaw with a walkthrough </p>
<p>is it possible to build a reasonably good quad/tri copter for around hundred bucks?</p><p>and what would be better for a first build, tri or quad?</p><p>thanks in advance</p><p>PS: really cool dat your still replying to comment on an old instructable</p>
Hey try a quadcopter before you get to a tricopter because a quad is much more stable and has lesser failure points. You can build a good quad for about 225 bucks maybe cheaper if you sacrifice the motor! A tricopter can be made in about 175 dollars (both costs include a radio). Btw build a mini quad it's fun. <br>And yeah I like helping people build stuff! And feel free to ask anything!<br>
<p>is it possible to build a reasanbly good quad/tri copter for around hundred dollars?</p><p>and what would be the best choice because its my first multirotor?</p><p>thanks in advance</p>
<p>Great instructible! Thanks for the links to compatible parts--I find Hobby King really hard to shop--your links made it possible, and very resaonably. Thanks!</p>
<p>You are welcome!</p>
<p>how much load can this lift</p><p>can it lift 2kg?</p>
<p>It may.. If you use bigger props, lower kv motors and a larger battery. </p>
<p>how do you connect the propellers to the motors</p>
<p>hey can u guide me to make a autonous arduino crontrolled tricopter</p>
<p>hello there,</p><p> i have setup the kk2.1 as per my required setting but , it shows that no yaw connection . though i have connected the servo to M4. secondly, i could not arm the tricopter...... i have calibrated the escs and all... </p><p>i am quite frustrated ,, and waiting for your reply..</p><p>sourav D biswas.</p>
<p>hey!</p><p>i think you might have made some mistake. </p><p>follow this video. and REMEMBER to remove your props before setting it up.</p><p>and which radio are you using? </p><p><iframe allowfullscreen="" frameborder="0" height="281" src="//www.youtube.com/embed/UZ4AaI6KPhA" width="500"></iframe></p>
<p>HI AGAIN PAWAN!</p><p>I just wanted to know which servo exactly are u using , the tg9e shown in the pic or the metal gear one , if you are using the plastic gear , u r going to strip it in no time</p><p>my friend! and the metal gear one is also crap, use a more reliable and expensive one like the bms</p>
<p>HEY PAWAN!</p><p>I LITTLE TIP FOR U OR ACTUALLY ANYONE WHO ORDERS FROM HOBBYKING .ALWAYS TAKE REGISTERED AIR MAIL AS THE SHIPPING OPTION , IF U DON'T WANT TO PAY ANY DUTY CHARGES!</p><p>BTW , I AM ALSO MAKING A TRICOPTER JUST WITH ANOTHER POWER SETUP .GIVE ME UR EMAIL I 'LL SEND U THE PLANS F U WANT</p><p>CHEERS!</p>
<p>hey it's incredible, but my budget is a little bit low .Can I make a tricopter using three new helicopters ? and is fitting a yaw necessary .</p>
Haha! Sorry for the late reply :P <br>you could surely try it. But I am quite sure that due to no gyroscope controlling all three motors of the helicopter at once, Each motor will run at different speeds therefore you may be able to get it airborne but it will surely shoot across the room. And also think about how you are going to control it. If you do make it ,send me a pic :D
. You just have to gear the motors and place them on the three respective sides(something like the syma quadcopters). Solder the wires to the helicopter board.Although that will cut down the cost of the speed controllers,it wouldn't lift a heavy frame or camera and therefore people recommend using brushless motors and speed controllers. As for the yaw, yes it is necessary as it provides direction and stability to the copter
<p>Total cost?</p>
<p>according to the comments on the charger page,people say that it wont charge a battery more than 800 mAh so how did you charge yours??</p>
<p>Hey I am new to this and thought it would be a cool project to do and have a few questions.<br>1. Is there any benefits to building a tricopter over a quadcopter? </p><p>2. With such a setup, can I use any voltage and mah battery or would I have to use a specific battery power?<br>3. If I wanted to later add a FPV camera, would I have to use a a different setup?</p><p>4. I have an older transmitter from a rc helicopter called the Eagle 50, would it be possible to use this transmitter?<br></p><p>Thanks!</p>
<p>Hello Mrpaddington! </p><p>1) They are a little different. The tricopter is capable of taking good aerial video without a gimbal due to its yaw characteristics, But if the servo stops working during flight the tricopter goes for a toss! The quadcopter is more stable compared to the tricopter and is easier to control. </p><p>2) It depends upon your motor and ESC combination and also how big your tricopter or quadcopter will be. Mostly people use a 3s setup for their quadcopter or tricopter. But again it depends on the motor and esc.</p><p>3) You can add a fpv gear to both a quad and a tri!</p><p>4) Nope, you cannot use that transmitter for any of the copters. I suggest you to go in for the turnigy line of transmitters like the 9x... </p><p>I own both a tricopter and a quadcopter! I suggest that you should go in for a quadcopter because it is easier to fly and easier to maintain! (And trust me you are going to crash a tricopter! :D)</p><p>Send me a private message on instructables about your budget. I will send you a list of parts you need to buy! :) </p><p>Regards,</p><p>Pawan V</p>
<p>Thanks a lot man :)</p>
<p>what actually makes the thing fly?? Plz reply.. I'm new to all this</p>
<p>the combination of the entire setup is what makes it fly. </p><p>The flight controller (here called gyro) is the &quot;brain&quot; of the tricopter, the receiver is the part that allows the tricopter to get information from your transmitter on the ground.</p><p>the flight controller sends a signal to the Electronic Speed Controllers (ESC) which, in turn, drives the motors. the motors generate the thrust needed to get of the ground.</p><p>while in flight, the flight controller uses the data from the gyro and the accelerometer sensors to constantly make calculations and adjustments to remain a steady flight.</p><p>Also, the commands you send to the tricopter using your transmitter will me added to the calculation of the flight controller. The flight controller will change the output signal to the speed controllers (or, in the case of a tricopter, the tail servo) slightly, and because of this, the motors will turn faster or slower, which results in the execution of the command you send to the tricopter.</p><p>so its not really 1 thing that makes the tricopter fly, its a collaboration of the entire setup that does the trick! :)</p><p>I hope I helped you and if you have any more questions feel free to contact me!</p>
Thanks
<p>@fysfys, thank you for your input. Very well written! </p>
<p>hey if i want to make wired i mean without transmitter n reciver soo who can u i do that?????</p>
You can only do that if you want to get butchered, Because you have to maintain distance with the copter when flying it.
<p>hey if i want to make wired i mean without transmitter n reciver soo who can u i do that?????</p>
<p>Sorry,for asking you this silly question.We cannot build a tricopter without a gyro.</p><p>Anyway thankyou for your explanations!</p>
<p>Can I do this project without a gyro? </p>
<p>Can you pls tell me about the yaw mechanism? What is the use of it? Does it have anything to do with the Tricopter's flight?</p>
<p>Yes sure!</p><p>The yaw mechanism is basically a mechanism which helps the tricopter to spin in the desired direction! left or right. if the motor is yawed towards the right the motor moves towards the left, vectoring the thrust towards the right and thus moving the tricopter towards the right.</p><p>yes the yaw mechanism is very important! without it the aircraft will spin in an uncontrollable way and will crash every time you try to fly it. This is because of the torque of the two motors which spin in the same direction and one which spins in the other direction, which creates a torque which is greater in one direction and causes it to spin in that direction. For this a motor is put on a movable axle which can tilt apposing the torque, the tilt is precisely controlled by the gyroscope for a smoother flight! </p><p>Yes you will need a BEC type esc for this project</p><p>see to it that your motor does not take more than 25 amps if you want to use a 30 amp esc.</p><p>can you tell me which motor you are using? If a motor is rated at Max 15 amp then 18 to 20 amp esc even a 30 amp will do! But if you are using a motor which has a rating of 20 amp then a 20 amp esc will NOT do! You always need an esc which has a higher amp rating than the motor! (at least 4 or 5 amps more) </p>you could use his help! <a href="http://rcexplorer.se/projects/2011/09/the-tricopter-v2-5/" rel="nofollow">http://rcexplorer.se/projects/2011/09/the-tricopter-v2-5/</a> follow his steps! use the same flight controller as i did its very good!
<p>Can I use a BEC type esc for this project.</p>
<p>Can I use a Turnigy Multistar 30 Amp Multi-rotor Brushless ESC 2-4S instead of a Turnigy Multistar 20 Amp Multi-rotor Brushless ESC 2-4S.</p>
<p>Can you pls tell me how to calibrate the esc.</p>
<p>It is very important and easy to calibrate an esc. If an ESC is not calibrated each motors will spin at different speeds and will cause a crash!</p><p>steps: </p><p>1) remove the props (very important!)</p><p>2) turn on your receiver with a separate power supply. You can use the other ESC on the battery port of your receiver remember no props on the motor </p><p>3) turn on your radio to full throttle position</p><p>4) plug in your ESC which needs to be calibrated on the throttle channel and give power to that ESC</p><p>5) After hearing one beep on your ESC quickly throttle down to 0%</p><p>6) the motor will make a few more beeps check for a smooth throttle response! </p><p>7) do it for all the motors and ESCs</p><p>And can you tell me which ESC are you using? so that i can help you better!</p><p>-PAWAN.</p>
I am using a Turnigy Multistar 20 amp esc.<br>Anyway Thank you!
