"I would say: Don't do that! Most likely you either shortcircuit something on board or mess it's RF design and tuning. RFDs have specially designed RF PCBs and adding more material on it would most likely kill it's original design as…"

Jani Hirvinen replied to Aussie in AZ's discussion 3DR telemetry no longer supported by 3DR....options?
"Yes that is possible too but currently we don't support it that way. Why? As most of RC TXes don't output anything else but PPM signal and currently RFDs cannot take PPM signaling in. There has been plans with Seppo to make one adapter…"

Jani Hirvinen replied to Aussie in AZ's discussion 3DR telemetry no longer supported by 3DR....options?

Jani Hirvinen replied to Aussie in AZ's discussion 3DR telemetry no longer supported by 3DR....options?
"Nope.. That won't work on those 3DR radios as their Si1000 CPU just don't have enough power to do encryption. That's why Seppo changed CPU on our RDxxxx modems to provide enough computing power to make encryption. Again HopeRF HM-TRP…"

"Yes we all know that. That's why we upgraded our modems to use those new RF+ modules as they can offer an encryption option to prevent this to happen. It's not issue just with 3DR based modems, it's an issue of all open communication…"

"@Gisela, No i don't say that Chinese copied those chips. That's the way how they have been designed. And like you said, yes they store only almanac on main chip nothing else. If you need to save settings you need external memory for that. "

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

Hi JP

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???

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?
