In any major new product release, there are last minute ‘hiccups’ which need documenting. The Vortex is no exception, although the hiccups so far have been pretty minor.
So here is the list of ‘stuff’ that a new Vortex owner needs to be aware of.
Last updated: May 28th, 2015.
1) Motor Differences
Due to the challenges of scheduling the delivery of huge numbers of motors from the motor supplier, and the time that it takes to develop an OEM version of a motor, there is a difference in the motor shipped in the first Vortex boxes, and follow-on units.
The motors have exactly the same performance, but there are a couple of notable differences between them, namely:
a) Color: The stock T-Motors have a silver case, with a black band. The ImmersionRC OEM motors are all black, with the ImmersionRC logo engraved on the side.
b) Prop Mount: The stock motors have a swappable prop mount, with either 4mm, or 5mm shaft diameter. The ImmersionRC OEM motors have an integrated prop shaft, 5mm, with a standard thread (no CW/CCW versions).
c) Prop Nut: The stock motors have a ‘domed’ nut which has a tendency to disappear in harder crashes. The OEM motors have a lock-nut with a nylon insert to ensure that they never spin loose in flight, or in a crash. Since a reverse-thread is not used, these can be replaced with readily available parts if lost.
2) Carbon Arm Differences
During early production, the yield of the carbon arms was lower than expected due to the proximity of the outer motor mount hole to the end of the arm. In practice, this doesn’t affect the strength of the arm, but production yield had to be increased, so a change was made.
The change makes the carbon fiber arm longer by 1mm, and a corresponding change extends the plastic motor mount by the same amount.
To ensure that customers do not receive incompatible arms, and plastic, the carbon crash kits, which contain the arms, are all shipping with a set of compatible motor mount plastic.
For crash repair which has the old arm, and the new plastic, the 1mm length difference is not a concern, and will just leave a slight gap between the two which doesn’t change the strength of the part.
3) OSD Text Jitter
All of the first batch of units shipped with a firmware image with an unacceptable (in our eyes) jitter on the edge of the OSD text, especially visible with larger LCD screens.
This was fixed with a firmware change, v126.96.36.199, which is available on our website.
4) NTSC Issue with Intermediate Firmware
At the request of a US reseller, a firmware image was created to allow bands not legal in the USA to be disabled (Boscam E for example) for domestic shipments (a common practice to keep the FCC happy).
This image was used to update a number of Vortex for shipments around the 13-15 May 2015, and was numbered v188.8.131.52.
This firmware image works well with the standard camera jumper setting for PAL mode, but the OSD text is corrupted if the jumper is removed for NTSC mode.
Since just about all of the LCD Displays and LCD Goggles in the FPV world auto-switch between these two standards, this is not a major issue, just leave the camera in PAL mode.
Firmware release v184.108.40.206, available from the ImmersionRC Vortex Website Page will resolve this issue.
5) Arming issue with some radios/receivers.
Due to the immense number of different combinations that can be made with radios and receivers on some combinations the Vortex refuses to spin the motors after arming. This is simply due to the fact that the endpoints are not out far enough for it to be able to do that.
Please configure the endpoints in your radio so they are less or equal to 1000us on low and more of equal to 2000us on high. The actual values can be checked in the CleanFlight application.
For a typical Mode 2 configuration pushing the left stick bottom right arms the motors and will spin them up idling and pushing the left stick bottom left will disarm the motors and stop the motors again.
6) USB connector breaking off
On the first few Vortex kits that left the factory the foam piece in which the Vortex was shipped has a very snug fit around the USB connector at the back. Due to the USB connector slightly protruding from the back of the Vortex it can get snagged by the foam and break off when the Vortex is pushed down into the foam with sufficient force.
In order to prevent this from happening we’ve modified the Vortex to have an extended lip at the back protecting the USB connector. However for the kits that lack this extra protection we highly recommend using a knife of Dremel tool to cut away/remove the excess foam at the back so the USB connector cannot get snagged by the foam.
