AT3520 Long Shaft KV720 + 14 x 7” prop
- max thrust = 4.8 kg
- Costs $80 - need to buy
- Voltage draw 17-18V
AT3520 Long Shaft KV550 + 14 x 7”
- max thrust = 4.1 kg
- Costs $80 - need to buy
- Voltage draw 20 - 23V
AT4130 classes aren’t suitable, they’ll require 2 LiPos and we are restricting to 1 to maintain under 5kg. They are also $110.
50 Propdrive V2 50-60 270KV
- Kinda heavy (~454g) but could work. Will be difficult/impossible buying extra parts if we have them still in the Bay
