All rewards have shipped!

Posted by The Quadshot Team (Creator)

We are incredibly happy to report that we've assembled, boxed, and shipped the last batch of Mochas, which mean that all of our Kickstarter rewards have been delivered!! If your Mocha is one of this last batch, you should have a Kickstarter message with the tracking number enclosed.

It has been an amazing journey for the four of us - we thank all of you again for your continual support and understanding! While in some ways the process felt like it took forever (and it certainly took a lot longer than we thought it would!), in just over a year we've gone from a few prototypes, through numerous design changes, multiple revisions and production runs of Lisa, Lia, and the Aspirin IMU, vendor sourcing, samples, and production, mold tool manufacturing and revisions, software development, packaging design, documentation, shipping (on a ship!), and of course assembly... whew!

We hope you will keep in touch with us and the other members of the Quadshot community on our user forums - share your experiences, comments, and questions, post photos and videos, and get together for group "quadshooting" outings!

We also just updated our video gallery page - Darren Kitchen, a Mocha backer and producer of the web show hak5, recently visited us and shot a great unboxing/flight prep video, as well as several split-screen videos covering all the flight modes - they are great if you want more guidance in addition to the Mocha User Manual on our documentation wiki.

Lastly, we formed Transition Robotics, Inc. last year as an Open-Source-focused company working on both hobby-market RC aircraft and electronics and UAV consulting. Check out our web store if you find yourself in need of spare Quadshot parts, want to get autopilot and IMU flight electronics for traditional model-airplane- or multicopter-based UAVs, or have friends that want a Quadshot of their own!

Cheers and happy flying!

Shipping update!

Posted by The Quadshot Team (Creator)

Hey all, we're a bit overdue for a status update :-P

We (and especially Chris!) have busy getting your rewards shipped. Today we hit a nice milestone, we sent out the 100th Mocha! Overall, our reward fulfillments look like this:

26/26 Decafs, 3/3 Lattes, 31/31 Cappuccinos, 100/141 Mochas, 32/32 Espressos, and 6/6 Kopi Luwaks have shipped!

If you are expecting a non-Mocha reward but haven't received it yet, please contact us!

International Mocha backers, please note that USPS recently disallowed shipment of lithium-polymer batteries, so while your airframe ships USPS International Priority, your flight battery ships separately via FedEx International Priority.

Lastly, we hope you've joined the Quadshot forum at to share your experiences and ask questions - we also keep this forum thread up-to-date with shipping status every week.

Cheers and have a great weekend! Thank you all again for your support.

Quick Update

Posted by The Quadshot Team (Creator)

Hey all, just a quick update on production.

Mocha: Airframe assembly and testing continues - we’ve now put Lia brains into the first 20 Mochas, and are testing them individually to make sure we did everything right :-) Most excitingly, we have shipped the first ones! We will be shipping them out in the order they were pledged.

Espresso: We received the Lisa/Ms and Aspirins with the new barometric pressure sensors, and Piotr got them all flashed, soldered together, serialized, and tested:

We shipped out the first 18 Espressos and first Mocha (lower left) on Wednesday the 25th:

Unfortunately, we are now hearing that we forgot to put the bags of ESCs into the Espresso kits - our apologies! We will ship those separately to the affected backers ASAP and we hope to ship the rest of the Espressos next week.

Kopi Luwak: We finally received the AirSTORM COMs from Gumstix yesterday (27th). They are otherwise all assembled, so we will flight-test them and hope to send them out next week as well.

In other news, we are currently in Las Vegas attending the DEF CON 20 conference, where we were invited to give a talk on the Paparazzi software and hardware that form the core of the Quadshots. If you are attending as well, our talk is tomorrow, Sunday, the 29th at 4 PM in track 2.

More shipping updates soon!

Shipping kits - and building lots of Quadshots

Posted by The Quadshot Team (Creator)

Hey all, since the container arrived we’ve been hard at work getting Quadshots assembled, boxed, and shipped out. Here’s the status of everything:

Completed and shipped out on June 21!

Completed and shipped out on June 21! We know of one backer, Anton, that built his Cappuccino around a Lisa/M v1.0. He’s posted videos on youtube: maiden hovering flight and first mode 2 flight.

We can’t wait to see more videos from all of you!

Obviously the biggest task - we’ve built about a third of the airframes so far. Chris is the assembly Zen master!

On the electronics front, we’ve been getting lots of assembled boards from Dallas Electronics:

The 150+ Mocha-bound Aspirins arrived first, and Piotr and Pranay have checked each one for functionality:

While testing the Aspirins, we were gratified to see that they all have really nice and consistent output without any extra calibration required - we’re glad Piotr updated to the IMU-6000!

The Lias also arrived - here’s the first 30 awaiting their bootloader:

Jeff made some jigs to assist Piotr in flashing the bootloader and to precisely align the Aspirin onto Lia for soldering:

Lastly, the RC receivers have been rebuilt with the correct firmware on them and are due to ship back to us today, so we should receive them next week - fingers crossed!

We have a little surprise for the Espresso backers that has turned into a good news/bad news thing. The good news is that Piotr upgraded the pressure sensor from the Bosch BMP085 to the Measurement Specialties MS5611-01BA03, which is mounted on Aspirin rather than Lisa. The new sensor is more accurate, has lower noise, and a faster measurement output rate, all of which should improve altitude sensing quite a bit. Unfortunately, the bad news is that the vendor accidentally sent us the tail-end of the component reel (small electronic components are sent on a what looks like film on a reel, with each part sealed into a pocket in the film). This meant that there were lots of empty spots where the sensors should have been :-( The vendor sent us the rest of the parts, but that delay, coupled with the July 4th holiday, is why the Espressos haven’t shipped out yet.
In any case, the Espresso kits are otherwise all packed up and in zombie/Dr. Frankenstein mode (waiting for braaaaaiinnnsssss....)

Kopi Luwak:
Chris has assembled all of the Kopi Luwak airframes. We decided to follow Gumstix’ recommendation and upgrade the modules from the Overo Air (TI OMAP 3503 @ 600MHz) to the Overo AirSTORM (ARM Cortex-A8 @ 800MHz-1GHz). However, stock has been in somewhat short supply - our order has been on backorder for more than two weeks, but we’ve contacted them and they expect them to ship by the 19th.
As soon as they arrive, we will install the Lisa/Ls and test-fly each one before shipping them out.

We know you are all very excited to receive your rewards (especially the Mochas!), and we’ll post more updates as assembly proceeds. Thanks again for your patience in the home stretch!

Now back to the shop to build some more Mochas...

Quadshot parts are here!

Posted by The Quadshot Team (Creator)


Ahem. Sorry for shouting :-)

As you already know if you follow us on Twitter (@theQuadshot), the parts came in last Thursday! Our truck driver got a little lost on his way from Oakland, but we tracked him down and showed him the way. Then it was just a simple matter of unloading a 20’ container full of hundreds of Quadshots-to-be.

Everything was very well packed and seems to have made its trans-Pacific journey safely. We are working on building the subassemblies and packing kits, and hope to ship the first Lattes and Cappuccinos out tomorrow!

On the Mocha front, we found that the radio receivers had incorrect firmware loaded onto them and were not outputting a PPM signal (combined output of all six channels onto one pin), which Lia needs to read commands. We talked to the manufacturer and they acknowledged the mistake, so we FedEx’ed the faulty receivers back and they are making new receivers for us. They have told us we’ll get the new receivers quickly enough that we don't think it will delay Mocha deliveries.

For photos of the unpacking process and kit assembly, please check our blog!

More updates soon!
