New Easy Star Accessory - Electronics Chassis

Hello Everyone

The Easy Star Electronics Chassis is being added to the DIY Drones store today. This accessory allows you to mount your APM/Oilpan, GPS Module (Mediatek or uBlox), Differential Pressure Breakout, Receiver, and pan/tilt camera mount on your Easy Star. The chassis provides access to the CLI switch, USB connector, and the Reset button as well as providing a clear view of the ‘ABC’ LED’s on the Oilpan at all times. It is also compatible with two GPS modules; the uBlox module can be mounted to the vertical plate near the back and the Mediatek gps module fits perfectly on the shelf above that (or you could use some double sided tape and stick any module anywhere). Most receivers should fit on the top base and can easily route wires to the APM beneath. The APM is mounted on the bottom and once it is mounted there is no reason to take it out as everything is accessible, but if the need arises, the bottom plate is designed to pop out more easily than the rest of the chassis so there is no need to take it all apart.

The chassis will be sold in two configurations, one with the pan/tilt camera mount (which you might recognize from Jeff’s post earlier in the week) and one without. Hope you like it and happy flying.


ps. we have flown this with the camera configuration as shown and having the camera off center doesn’t seem to pose a problem. Mounting it this way allows for a less obstructed view, as well as the ability to look down :).

Looks great. Any comments on how to attach it to the canopy? You seemed to have drilled holes to the elapor?

The kit comes with magnets, you can use CA glue attach them to both the plane and the chassis. Since we are on the topic of CA glue, I would recommend the joints in the back of both of the semicircular pieces get a bit of CA glue in them. Its not necessary but for "hard landings" (aka crashes) everything will stay in place that way. Also if you buy the pan/tilt version, it doesn't hurt to take off a tiny bit of foam off to make room for the screw heads that hold the pan/tilt in place.

I built a similar pod for my CoPilot II and Ardupilot legacy by modifying a Readymaderc EZ* pod. The shelf for the Ardupilot clears the battery in the cockpit when the battery is mounted sideways in the bottom of the EZ*.

I like this design for the APM/IMU which will save me from having to modify another Readymaderc pod.

Hi Alan, it looks awesome!!! Just a tip, has the v1 sky surfer, which is the exact same plane as the bixler (i have both sitting on my dining room table right now).  I would LOVE to have one of these, readymadeRC sells a pan/tilt canopy for the sky surfer but a full electronics canopy would be superb.  One question, how does having all the electronics forward of CG affect balance? battery mounted under the wing ?

Hi guys, this is how we have our batteries set up to get the right cg.



apocalipse, thanks for the tip. I also bought a bixler for myself from Hobbyking's China warehouse a couple weeks ago. Since the US warehouse is still in backorder, mine might beat the one we ordered for 3DR. If that's the case ill hold off on assembling mine to model it and push these things out quickly.

How difficult would it be to modify this so one could look back at the tail?  Can you look straight up as well?

It really depends on the servos you get. If you get 180 degree servos then no problem. If you find your view to the tail is a bit obstructed, you could get longer spacers and raise the camera mount assembly. Continuous rotation servos would be cool on this thing, but then you have to make sure wires dont get tangled.

Does anyone know if this is compatible with the Hawk Sky?

That's great :-))

One of the platform I am using is a Twinstar II. Are there any electronic chassis for this bird ?
