First FPV flight in 2014

During winter I made a little breakout board that I mount directly on to the APM 2.5 board. On this breakoutboard I have soldered a voltage diver that is connected to the APM voltage sensor pin. On this board I also soldered some kind of plug-in slot for my analog RC module. Now the RC module is connected to the APM without any cable. I also mounted the Hobbyking HD Wing CAM.

The Y6 is flying stable and smooth. But the MAG is currently disabled because of EMF noise comming from the motors. This also influences the video capturing. I can easely fix this by extending the motor arms. But this makes my Y6 larger. When I have the time I'll try to benchmark this to find a save min distance between APM and this type of motor.

Test flight

So here are some more photos of the Y6 multirotor full carbon frame equiped with my diy motormounts, AX 2210N motors and 9x47 Slowfly props







And a little video to show that this frame fly's well. It's not a high power acro setup. But it still has ~ 3 to 1 thrust/weight ratio. You feel that on take off. It needs less then half throttle to lift off and hover.

The DIY Y6 carbon frame how-to

step 1:

So here it is. The full carbon Y6 frame. It's simple to make.

At first I glue the arms as created in my previous blog to the bottom plate of the frame. The bottom plate I used is a carbon fiber 150mm x 100mm x 2mm plate. Because I use round tubes its much more to place and mount them correctly when you glue them with 30min epoxy. When the glue is hard the proceeed to step 2

step 2:

Now glue the top plate on top of the arms. As top plate I used a 150mm x 100mm x 1.5mm carbon fiber plate. When you used high quality epoxy then this frame will be strong enough. If you do not have configence in the glue you used then drill some 3mm holes from top plate trough the round tube trough the bottom plate and add some screws.

I also drilled 4 holes in the top plate where I'll put anti vibration rubbers. All my electronics will be mounted on a second topplate. This will reduce vibration but will add extra weight. It is an optional feature.

step 3:

The landing gear. I wanted to keep the total weight of the landing gear below 100 grams. I have looked arround and the only options was a combination of carbon round tubes I used for the arms and an general airplane carbon landing gear. The landing gear is PT-Model 1300 and is rated to 1.3kg. As the total weight of my Y6 will be 1.3 ot 1.4 kg this landinggear should be enough for soft landings.

As in prevouis steps I first glue all parts togheter with 30min epoxy. When the epoxy is hard I drill some 3mm holes and make is stronger with screws.

step 4:

Fix the landing gear on to the bottom plate of the frame. I drilled 4 x 3mm. When this is mounted it should look like the photo at the left.

project start

My Mini-H Quadcopter project is closed. I'm currently using this quad to learn to fly by FPV with my fatshark goggles.

I'm also closing my other quad project  . This was a great platform to learn, practice and test. But it's a very strong, but heavy setup and adding an FPV cam to this setup would make it to heavy.

So I'm starting this new project. A Y6-Copter. Full carbon frame to make it light and strong. The 6 motors will give me enough lift to carry all electronics and FPV equiment. 6 motors should also prevent a crash when one motor fails in flight.
