AT3520 Long Shaft KV720 + 14 x 7” prop
- max thrust = 4.3 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
AT3520-5 KV 880
- T-Motor AT3520-5 KV880 Brushless Motor - Aerofly Hobbies - MultiCopters - AeroModels - FPV - UAV
- 3.8 - 4.2 kg thrust, probably connect a 14 x 7 prop (interpolating from KV 880)
- 3-6s
- We have one in the Bay
Turnigy G60 400KV
- 14x8 ~ 16x10 prop
- 5-7s Lipo
- We have 2 in the Bay. This is also a discontinued product. Turnigy G60 Brushless Outrunner 400kv (.60 Glow) (hobbyking.com)
AT4120 KV560
