Jani Hirvinen commented on Christiaan van Vollenstee's blog post Introducing the latest ONE from X-UAV
"One thing that I am a bit concerned is the propeller mount. How good is bearing, how much it lowers down the efficiency and so on. Also will there be replacement parts that can be accessed easily. Anyways, plane looks good and interesting design."

"Seems this project is dead. If the system actually works and is just not being produced for other reasons would it be possible to publish the circuit board design and sketch so we can make our own?"

"Jani, will your ASM (antenna tracker) code be open source or closed? This is crucial point for me. Just dont look for some insinuation in my question - both models has pros and cons. I just want to know what model will you choose. IMHO open source…"

"palo, no there are no updates for older ASM code as big tracker is based on our APM architecture. This way we can ensure better compatibility on future releases."

ArduCopterGroup @ jDrones

"Paul, those are normal ESCs that jDrones produces. If I am not totally mistaken, those ESCs on copters on the picture had all 20Amp ESCs (Picture is almost 4 years old already). Those most and ESCs were the base that all ArduCopters were build on.…"

"As far as I remember, we dropped HIL simulations as they were a bit too unreliable and it wasn't never full 100% hardware simulation. All simulation is done under SITL now."

6 Way mode switch gets life...

Finally after several iterations on PCB and electronics design, first jDrones ModeSwitches are getting to daylight.

First boards are fully operational and we are testing them with several of our test flyers. …

Ok now I have seen it "all"... For some reason I were not stunned to see that it was Lady GaGa who made this first.. But here we are.


On their video it looks a bit badly tuned but it flies. Unfortunately video cannot be embedded to Ning so everyone need…

Thank you very much for your help.
I have follow your link and I found it is tons of data to build Adrucopter.
I have read your profile and very glad. That you have stay in Bangkok Thailand.
Because I'm a thai people and live in thailand. I'm a student and try to finish my Bacherlor Degree with multirotor copter.Now i'm study hard for Adrucopter.

Best regards.

Single users will receive tracking/register number after their packets are shipped, that is normal way how ecommerce systems works. We try to ship 15-25 kits / day untill 1st batch is fully sent, 2nd batch starts to send when all parts are arrived.

How do we know what batch our order was in???
Thank you

Hi Jani,  Are any places to fly a fixed wing in Bangkok ?   I need to spend a few days flying .  Should I think about spending some time in Pattaya or Chiang Mai ? Thanks, Harry

Hi Jani! I am from Singapore (nearby) and I've got a very quick question for the Oilpan. If I connect signal wire of an analog sensor to analog port 8. Can I read it by using analogRead(62) or analogRead(AN8)? Tried to find some related forum posts but can't find a specific answer. Hope to hear from you soon!

Hi Jani. Loving the new hexacopter kit. Very nicely done. Does JDrones have led covers for the motor mounts?

Todd, thank you it was a pleasure to make that. More will come to it. Same goes for mount covers, they are soon on store with additional stuff.
