Product overview
T-MOTOR MS1503 polymer straight propellers are designed for multi-rotor UAVs and supplied as a two-piece pair. Their integrated two-blade construction uses Polymer+CF material, with a tailored airfoil for efficient flight, small deformation for stable operation and stringent control over dynamic balance. Each blade weighs 25g and has a pitch of 5.6inch (142.24mm). Recommended thrust is 1~1.5kg at 4100~5000RPM, with a recommended maximum of 4.5kg at 8400RPM. These polymer propellers are not recommended for coaxial setups.
The ambient operating temperature range is -40℃~65℃. Storage requires -10℃~50℃ and humidity below 85%, with sealed preservation for periods exceeding six months. The package measures 419*52*43mm and weighs 135g. Do not disassemble the propellers, and replace any that develop deformation or cracks following a fall or equivalent impact. Keep the propellers away from hostile environments containing H20, S02, N02, Cl2, organosilicon, cyanogroup or phenol.
