Aside from a few special cases, we have now finished shipping all units.
We have no stock of the control boards left due to the number of replacements sent out. The aluminium frame was designed to be an awesome way of dissipating heat from the ESCs, it turned into a terribly frequent cause of electrical shorts.
Resultantly we aren't able to send out any more replacement boards (except to those people we have already been in email contact with). Please ensure you take every care to protect your R10 by insulating the GPS antenna, the 2.4Gz Hypo antenna and making sure no wires are chaffing on the frame. It is still safest to also insulate your ESCs completely from the frame. Use electrical tape, kapton tape, velcro, heatshrink and other readily available and cheap methods.
R10 is a reasonably small quadrotor and the cable management isn' great, continued use of the quadrotor can eventually lead to a short even if it is working fine now, so please follow our advice above.

This firmware has "Normal" Flight mode enabled only. Work is progressing on Acro, Easy and Auto. It is compatible with the telemetry output except for GPS location.
2 IMPORTANT POINTS:
1. The craft no longer auto throttles off, just like a neutrally bouyant balloon will bounce off the ground, so will your R10. To land smoothly, throttle right down momentarily before you touch down.
2. The angle limit is set to 0.3 Radians I believe, slightly less than before. Users with telemetry set up can change this parameter it is called Angle_Lim
I have put over 20 test hours on this mode, I hope it serves you as well as it works for me.

Hi all, just to say that after some (much needed) absence, I'm now back on the scene to help Henry handle support requests. If anyone still has not heard back from us after submitting a support request on the website, hold tight, we're rapidly clearing the backlog.
Unfortunately we've discovered that a couple of the support email addresses, including email@example.com and firstname.lastname@example.org were forwarding to a black hole instead of to the CRM system. This was totally my fault - I had set them incorrectly. I've now fixed them. Please could anyone who had originally sent support requests to one of these email addresses send them again, or use the support page? We will be able to get back to you as soon as we can.
We have some stock left of the original parts and we have more motors, ESCs and motor spare packages arriving in the US soon.
In the meantime, some backers have been amazingly supportive on the forums and found some sources for motor spares. I've collated the information below:
There are 3 options available for repairing broken motors:
Shipping has been monumentally slowed down by the ESC repairs. Currently we have shipped to 330 Backers between the US and the UK. That leaves slightly over 100 shipments to still go out. We are shipping small batches as soon as we have the ESC heat spreaders cut down and resealed. We cannot unfortunately provide tracking numbers for all the parcels as some of the courier services only provide tracking to us.

New Thalamus Firmware and source code:
Please remember to recalibrate the Magnetometer after loading new firmware versions. And please be aware that loading new firmware versions will reset all parameters to the defaults for this firmware version.
AUX/CH5 Switch determines simplicty mode when transmitter and craft are first turned on. Ultrasound Mode thereafter.
Further tweaks have been made to the tuning of the craft, including:
- Adjustment of the Yaw deadzone
- Increased D Gain to assist smooth take-off and landing (Always remember to CENTRE YOUR TRIM tabs, then adjust in flight as necessary, remember wind will tip as well as translate the craft)
- Motor Ouptut Filtering to maintain smooth and stable flight
- Reduced Gyro Averaging to decrease take off slop further
- Increased Landing Detection Threshold to prevent motor shutdown at the wrong time
- Yaw is re-enabled after a short time, even if the ultrasound module is not plugged in, or is not getting a good reading.
The source code is all contained in main.c
We will be releasing some instructions about compiling this code into the firmware.bin file (which is what you load onto Thalamus) in the near future, and we also hope to provide an online compiling service. We know some of you are talented and knowledgable about these things and will be able to compile it yourselves without assistance. Even if you're not sure how to compile the code, we are sure you will be interested to take a look at what is running on the microprocessor!
A number of people have been interested in the frame CAD, in line with this being an open, community project with have decided to release the CAD.
Please find STP, STL and dxf files for the Diagonal, Side, Plate and Mount pieces below:Best,Henry and the UAir Team
Hi UAir Community,
UAir had the pleasure of being featured in Zakia Uddin's Guardian article called, "DIY Drones."
Thanks for being part of our "maker" movement.
(Bumped, further information added below)
If you haven't yet recieved your kit, you don't need to worry about these fixes. If you have recieved your kit, please read though the below to understand the problem. If you have done that and are in anyway unsure how to proceed, please submit a request and we'll help you individually. Don't plug in the battery until you have worked it out or got help from us!
Following extensive testing throughout the night we have found that the thermal insulation that the ESC manufacturer used is failing on several peoples ESCs. We apologise for this issue, and will work with the manufacturer to ensure that this is not a problem in the future.
This manifests itself worse with a telemetry pack installed but may affect some standard users too. We will be rectifying this issue before we ship the remaining units.
For everyone who currently has their R10 Kit, we strongly advise that you follow the video below to help prevent part failure, BEFORE you connect the battery again. See the following video:
We are continuing the production of the remainder of the instructional videos. The shipping of the remaining R10 units will be delayed by one or two days as we rectify this problem.
It looks like in some rare cases, there are double shorts to the now isolated ESC heat spreader. These are hard to deal with, please IMMEDIATELY unplug your battery if you smell or see anything unusual near any of the ESCs. If you are able to electrically test your ESCs, please test that none of the wires have low resistance between them.
To explain the problem, Yuan has produced a video:
We are considering changing ESC manufacturer if they cannot make the necessary alterations to their assembly process.
We are electrically testing all ESCs that we have modified, before we ship.
We must once again thank you for your patience and understanding over this problem.
Henry and the UAir Team
After trying out several solution, it appears that the best method is to cut the heat spreader down to size to avoid any possible shorting. We will be doing this on ESCs being shipped out.
To answer questions some have asked about why we did not notice this problem during prototyping, this image shows why. The ESCs we received as samples from the same manufacturer look different. Notice how the solder blobs are on the other side of the board, where they don't risk contacting the heatsink. This is an issue we need to take to the manufacturer to have it sorted.
