Replacing a damaged propeller on your POWERUP 4.0

If one of your propellers broke on your POWERUP 4.0, before you replace it with a new one, it is important to understand why it broke, this will help eliminate damage to the props and motors.

POWERUP 4.0 rear pusher propellers are intentionally located on the rear side of the module in order to eliminate damage whenever you crash. the props and motors are very sensitive and any direct impact may cause permanent damage to the 4.0 module. 

Common reasons for breaking a propeller:

• Flying in sub freezing temperatures -  Plastics tend to become brittle in extremely low temperatures. The Propellers are made of reinforced plastics but will be less durable in these conditions. best is to fly on warmer days when temperatures are above freezing.
• Flying over hard surfaces like concrete will increase the hance of breaking the propeller and any other parts of the POWERUP. Always chose a soft surface to fely over like grass, dirt, snow.
• Flying indoor increase the chance of running your POWERUp into some hard surface and increasing the chance the props will get damaged. If flying indoor choose spaces that are designed for indoor RC flying.
• An unbalanced Airplane may cause your plane to stall and tal dive. in this case the tail may get a direct impact and cause permanent damage to the propellers and motors. A Tail dive is highly unlikely if using any of our recommended designs, if you asre experimenting with your own designs and adjustments, be sure to do a test glide fist and see that your plane is well balanced for flight before throttling up.

Removing a damaged propeller:

• Before removing the propeller, locate the replacement propeller in your POWERUP kit or your Spare Parts Kit. PLEASE NOTE -  the left and right propellers are not Identical! The right propeller turns clockwise and the left propeller turn counter clockwise during flight, therefore the shape of the left and right propellers are mirror image of each other. it is critical to locate the correct propeller before replacing it. please look closely at the curved shapes and verify this. failing to install the correct propeller will cause the plane to crash.
• To remove the broken propeller from the motor, you MUST use an extracting tool, this can be a screwdriver, tweezers or a propeller extractor. NEVER pull the damaged propeller, this may dislodge the motor and damage the module permanently. 
• Once the broken propeller is extracted locate the correct propeller as described above and install it very carefully by applying mild pressure on the center hub only. if you apply pressure on the blades they may warp or break. A small one mimimiter gap is allowed between the propeller and the motor.

Please see the movie below showing how to extract the broken propeller and how to install a new one.
