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?
