Flight Characteristics
•5” Propeller
•Motor
•0V-11V
•4000 (RPM/V)
•Max RPM (no load): 42k RPM
•Weight: 40-70g
Theoretical Load
•Total Weight 497g + x
•4x Motors = 160-280g
•Li Poly = 180g
•2x Carbon Fiber Plate = 13g
•4x 5” Carbon Fiber Tube = 24g
•Other Materials = x (g)
•Static Thrust per motor
•15k RPM = 180g lift
•20k RPM = 330g lift
•25k RPM = 510g lift
•30k RPM = 740g lift
•Estimated copter lift
•4x Motors @ 16k RPM
•800g Lift

Risks and Contingencies
 Broken Parts during testing
 Ordering multiples of parts
that are likely to be broken
 Insufficient thrust to lift
payload


Bigger propeller
Adjust battery size
 Overall Project Structural
Failure

member(s)

Purchase a commercial quad
copter body kit
 Over budget
 Remove the camera from plan
 Materials for construction
Team Syntech
 Not enough time
 Reduce features/capabilities
from low category
 Going out of control
 Netting and a tether
 Kill switch and hover switch
 Unavailability of team

Shift work to other members
Reduce features/capabilities
 Controller does not work
 Buy off the shelf components
(Arduino)
