I’ll give it a Tri…

I’ll see your Quad and raise you a Tri.

So… as my brother posted eariler he is building a quad-copter. And since I wanted to join in on the fun while not being a copy-cat I decided to design and build a Y6 tri-copter. It has the same similar concept to the quad-copter, but with only three arms. At the end of each arm there are two motors which totals to 6 motors. Now that the intro is out of the way, here we go.

After reworking my budget and finding out just how much I have to spend on this thing I have been able to start buying some stuff for the Y6. And before anything has arrived I’ve begun designing the center plates.


the bottom plate will be much larger than the top because the battery will mount underneath it.

Only 3 esc’s are showing because the other three will mount underneath the top plate and it will all sandwich together.


The top plate will be much smaller because all it needs to do is give a surface for the flight controller to be mounted and also to hold down the boom arms (dashed lines).

So far I have bought the ESCs – 50AMotors – 2830-14Batteries – 4000mAh 11.1v 30C, and a carbon fiber plate – 12″ x 12″ x .1″

ESCs – When it comes to cooling I am hoping that because I got “over-sized” ESCs (50A instead of 30A) they will not be working as hard, ergo not as much heat? I am also going to have holes cut out beneath each ESC where air will be able to circulate through. And I might put an elbow fitting at the end of each boom (under the prop) so it will catch the rotor wash and channel it through each boom all the way to where the ESCs are – essentially blowing air onto the ESCs (I hope that made sense).

Flight Controller – I found a really cool DIY board kit that you actually solder all the parts together yourself. You save a lot on cost. And this controller uses parts from three $15 gyros. It’s certainly a cool project to tackle. I still don’t know, however, if I will go that route.

Can’t wait until it all gets here. The carbon fiber plate should get here Today!

It should end up weighing about 1100g, or 2.4lbs, and be able to lift about 2100g, or 4.6lbs. The goal is to carry an HDSLR

Give me your comments and let me know what I have not thought of, or what might be better in terms of design.
