Tricopter Build Part 2 – The making of the frame

Making the frame:

What you need in this step:

Some 2,5 mm plywood plates for the main frame.

10mm*13mm arms x 3 (should be at least 50 cm’s long)

10 x M3*25mm bolts.

10x M3 nuts.

Optional:

Washers (Spring washers)

Locktite

Getting started:

Firstly you need to cut your 3 arms or booms to the correct length. I made mine 50 cm each, for extra stability since i am gonna use it eventually for FPV. So you need to markup 50 cm’s and cut them there. Pretty straight forward:

The next thing you want to or should do is to print out the template from RCexplorers website here. Cut the main frame out with a scissor lay it on you 2,5 mm plate of plywood (or any other sort of wood that is strong enough) and draw around the template with a pencil or a permanent marker. Remember to draw two, as you will need two plates – top and bottom.

Once you cut your two main plates out you want to sand the edges or file them or something like that to make them more smooth. After that you want to go ahead and drill the holes needed for assembling the frame. What i did was to lay the two plates on top each other, and the template on top of those two and align them all so it’s a “snug fit”. Now clamp them together and take a 3mm drill and drill the holes where they are marked on the template.

Next up is to drill the holes in the two front arms. The last one (tail arm) doesn’t need holes because it is kept in by the 4 bolts surrounding it and pressing the plates together around it. You need to drill a hole in one (Only one!) end of each arm 20 mm in from the edge in the middle of the arm.

Now drill a 3 mm hole where you marked it and thats it.

Now from your spare length of the part of the arms you cut away. Cut a small piece of 4 cm’s in length and round to edges which will be the front edges. Now you can assemble the frame, and you now have a professionally made frame. All credits goes to David Windestaal from RCexplorer who designed this frame.

Tricopter Build series – Which parts? [Part 1]

Hello again.

Since the last time i posted a blog update i decided i wanted to build a tricopter instead. This will be done the same way as i did with the quadcopter series, only a little more detailed. I will be uploading the series with only a few days in between the videos, as well as posting the updates here on the blog. I am also currently working a “Complete tricopter guide” where i will be making a full write up on how to make the tricopter. This will be published in a few weeks.

Tricopter build – Which parts? [Part 1]

So basically part 1 will be to collect the needed parts. The parts i used was:

or
http://www.hobbyking.com/hobbyking/store/uh_viewitem.asp?idproduct=22446&aff=655899

Frame:
10mm*13mm*500mm arms. You need three 50cm long booms, which is 10*13 mm’s thick. Bought at local hardware store.
2,5 mm plywood for the two middle plates.

So this is basically part 1. These parts and links are also to be found under the parts tab if you click “Tricopter”.

Thats all for now. More to come shortly. Bye!

Quadcopter guide – soon!

I am right in the middle of writing a complete quadcopter guide. This will teach you how to build a quadcopter. I will be taking all my experience and work with my quadcopters into consideration when writing this guide. This will hopefully answer some of your questions, and hopefully help you to build one. That’s all for now.

Assembly video up!

New video is up! This is just the video where you will see the assembly of my Quadcopter v2.0. I haven’t flown it yet – the wind has been pretty bad, but it may be better tonight so i can take it out for a fly! Enjoy!

Quadcopter v2.0 Assembly

/Martin

Quadcopter v2.0 finished!

As you can see i the picture below the v2.0 of the quadcopter is now finished. I am in the editing phase of the assembly video which will be uploaded in the near future. I think it turned out pretty good. If you have any questions you can just leave a comment and i will try answer it the best i can!

/Martin

Oops – now for the V2 Quadcopter.

I was out flying it today no wind at all! But the balsa wood – which the arms/booms are made of – cracked, as i bounced of the ground. Or at least of of the arms got destroyed. So i off to making the V2 quadcopter. The parts list will be available from the “Parts” tab. The frame of the V2 quad will be of aluminum. It is a small bit heavier than the balsa wood – BUT a lot stronger. So it is well worth a go. You can see the shattered copter below here:

Here you can see the left front arm being crashed.

As you can see. Completely shattered. It’s sad i didn’t get in on video.

/Martin

Finally finished!

My quadcopter is finally finished. As you can see in the video below my landing gear kinda trashed out. Do you guys out there have any idea of solid build landing gear. It should be high enough to mount FPV Gear/SLR camera under the quad. You can either comment this post or comment the video on Youtube. And of course subscribe to my youtube channel and to this blog. The more subscribers i get. The more videos i will make. So it is up to you! Enjoy!
