New video! – Remove your props!

Remember that I always say in build and setup videos to remove the props (or not to mount them) when doing setup on the computer while having the battery plugged in?

I though I would do a demonstration video as to why you should do just that.

Charpu had his quad going bananas while doing throttle calibration. His story is very entertaining and a great reminder that it can happen to anyone of us. Watch the RotorRiot episode here:

Have you’ve had any similar experience? I would love to hear about it in the comments!

Air Bears – You can make a difference

Air bears is an absolutely awesome organisation dedicated to connecting RC pilots and local authorities to help in Search and Rescue missions of missing people.

It’s a volunteer based system. If you have a multirotor or fixed wing platform that you can keep on standby to help the local police or fire department in your area, you simply sign up on their website (there is a onetime fee of $25 to cover the registration process and you get a T-Shirt). You’re now registered on their global network of pilots. An online map will help the local authorities that need help, find the closes pilot and quickly get in contact. You can also help spread the word to your local authorities by giving them this brochure.

The goal of Air Bears is to have global coverage of standby ready volunteers to help reunite missing people with their families. If you don’t have an aerial platform that you can have on standby you can help out by donating to the cause.


New shipping calculating system

We’ve just installed a new shipping calculationg system which is going to be more precise than the old one. This means that you can now in most cases add more stuff before the shipping cost rises!

We’ve also updated the shipping costs to the new prices we have from PostNord for 2016.

If you have problems with the shipping options (most importantly, if you get the message “no shipping options available”!) please contact us by posting a comment below or sending us an email.


TriFlight Setup guide

Thanks to the fantastic work of Lauka and everyone on the forums, we now have a specially tailored firmware for tricopters dubbed TriFlight!
The new firmware vastly improves the flight performance of the tricopter as it features a ton of optimisation specifically tailored for tricopters. Among other things it features a custom in-flight adjustment for the thrust to torque factor of the powertrain as well as a equal yaw rate algorithm to get the same yaw speed in both directions.

The setup for the Tricopter V3.5 and the MiniTricopter is now made even simpler as the firmware is already pre configured with the correct PID’s and settings for the recommended electronics.

If you want to join the development, there is a +40 page forum post where this firmware was born and polished by our fantastic forum members. By tricopter pilots for tricopter pilots. Together we are strong!

If you want to print or cut your own Servo Setup Tool you can download the STL and SVG file here. Be aware that I have not tested if this file prints correctly. The file was designed by trial and error on my laser cutter. The file might need adjusting to get perfect 40° deflection.

Mini Tricopter back in stock!

The Mini Tricopter is finally back in stock! All backorders was sent out yesterday. Thank you for your patience and thank you for all your support. I really appreciate it. The Triflight code is coming along very nicely and the tricopters are flying 1000% better than the stock code. Hopefully we’ll move out of the beta and release the a v1.0 of the code in a not too distant future. Thank you Lauka for everything you have done. Also thank you to everyone else on the forums that have helped develop and improving on the code and providing feedback. Together we’ll soon conquer the world, ehm I mean the race tracks.MiniTriSnow

Servo setup tool and single frames

Tilt setup toolQuick update on the store; Added a servo setup tool to make it easier get the perfect center and exact 40° throw. Very useful in the setup of the Triflight setup. This will be included in the Tricopter and MiniTricopter kits from now on, or to be bought separately. Those that are waiting on their backordered Minis will get one with their order. The backorders will, incidentally, be shipped tomorrow!

Also added the option to buy the tricopter frames separately, in case you want to upgrade just one frame or accidentally destroyed one.

Pembroke wing

A couple of weeks back I heard from a friend of mine that the Swedish Rescue Training Center in Skövde was going to close down and that they were holding an auction for all kind of cool stuff. I immediately jumped on the interwebs and found the auction. Among the thousands of very mixed items such as firetrucks, CPR dolls, miniature models, projectors, chairs and such I found a Hunting Percival P66 Pembroke C.Mk 52

Tech talk on the FT After Hours podcast

V1A5BMJFThe awesome guys over at FT After Hours invited me to join the show for a new segment called “Tech talk with David“.

In this first instalment we talk a bit about how brushless motors work, how KV is determined and what affects how much watts the motor can handle. We also talk about how servoless retracts work, KK2 VS Naze32 and loads more. Of course we also discussed some other thins such as the new Slow Mo Time channel, and my resent purchase of an airplane wing.  The FT After Hours crew really are a joy talking to and it is an honor to be on their podcast.

If you’ve never listened to the crazy stories from Chris, Wayne, Andrew and Mike be sure to listen to their previous episodes as well.

The Tricopter V3.5

Got some news for you guys! Today the Tricopter V3 has been upgraded to V3.5!

Some minor changes has been made to the kit such as;

All fiberglass reinforced injection moulded plastic pieces to improve durability and quality. This includes the top and bottom wire holders, front spacer and all of the tilt mechanism piecesInjection moulded tricopter piecesThe V3.5 also have a larger wire dampeners to allow for larger batteries. New maximum recommended battery size is 40mm tall and 60mm wideWireDampenerNewLastly, the kit comes with the new style carbon fiber arms which were announced over a month back. The new arms are even stronger and more square than the previous model.ReallyLongStick3

The main reason for the new V3.5 name is to make it easier for people to find the new build video that is in the works. Since quite a few things have changed since the launch of the V3 a new build video seems appropriate.

The V3.5 has already been shipping out for almost 2 weeks, so if you’ve ordered one in the past fortnight chances are you’ve already received the new kit.

Rotor DR1 Q&A with Chad and I


October 27th at 2PM EST (11AM PST) (18:00 GMT) Chad Kapper and myself will be answering your questions on Reddit. Got any questions about the Rotor DR1 movie, the rotor universe, how the movie was made or general “drone” questions, jump over to Reddit tomorrow and join the “Ask me anything” thread.

For anyone that missed the release this past Tuesday; Rotor DR1 the movie is now available on Blu-Ray, DVD, Hulu and Vimeo.

Update! The chat is now live! Make sure to upvote the room.

Update2 thanks to everyone that showed up!

New supplier of (full length) carbon fiber arms

I’ve had some lead time and quality issues with the carbon fiber arms (remember this summer when they were out of stock for a month?) Well it led me to try and find a new, more reliable supplier. I did find one after much searching and last week the first batch of arms arrived! Unfortunately with the release of the mini, I really haven’t had time to post anything about them until now. As the old arms pretty much ran out last week as well, those of you that have ordered the Tricopter v3 recently might get the new arms in your package.

10x10mm carbon fiber boom

With the change of manufacturer we had to make a new mould. So I decided to make the arms more “square” than the old ones. They turned out great with very crisp edges.

As I’m really pleased with the arms, I have ordered this kind of arms for the Mini as well, but it’ll take about a month or so before they get here (I cheated a bit and used the new kind in the build video though). At this time it’s only the full length arms that have changed.

If anyone feels really strongly against the new look on the arms or need to replace only one on an existing tricopter, you can add a message to your order requesting the “old arms”. If you do, the arms that you receive might have some aesthetic defect, such as scratches or blemishes (as the only arms I’ve got left are the second quality sorting). There is however no technical issues with the arms, it’s just esthetics. This option is of course limited in time, when I’ve run out, they will be out for good and only the new kind will be available. You can mix the old and new arms without any problem. They are the same size and everything fits the same. They are simply more square. All new kits sold will be sold with the new style arms.

New FPV video – “Norway”


Anders Lindström, my wife Johanna and I decided to take a 10 hour drive to Kjerag mountain in Norway. This was before the fantastic custom firmware made by Lauka, which have made a phenomenal difference to performance. So the video is not as stable as it would be today. We also had problem with jello in the footage due to the sloppiness in the laser cut prototypes. The milled frames in the store doesn’t have this problem.
