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! 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?
