Summary
AT3520 Long Shaft KV720 + 14 x 7” prop
max thrust = 4.3 kg
Costs $80 - need to buy
Voltage draw 17-18V
AT2820 KV1250
10 x 5.5 prop
max thrust 3.1 kg
$60
Plane flies slower, drag will depend on v^2 so 0.5 : 1 thrust-to-weight ratio might work?
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
14 x 7 prop
4.9 kg max thrust
$110
