5-inch Red Four-Blade Crossing Machine Propellers, Two Pairs

This listing is for a two-pair set of 5-inch crossing machine propellers, each with four blades in a crossing layout. They are made from plastic and supplied in red, and the set is listed for youth aged 15 to 35. If you fly a quadcopter or crossing machine and need spare rotor blades, this pack gives you four propellers in one bagged set. The source information is straightforward: size, blade count, colour, material, age range, and pack contents. There are no pitch, weight, thrust, or motor compatibility figures given, so the practical approach is to match the 5-inch size and four-blade format to your existing setup. Red blades are easy to spot when you are checking orientation or looking for a dropped propeller in grass. Because the set contains two pairs, you can keep one pair fitted and one pair as a spare. No performance ratings or flight-time claims are made here, and none should be assumed.

Features and Construction

The core facts for this product are simple and specific: 5-inch size, four blades per propeller, plastic material, red colour, and two pairs per pack. That is enough to judge whether these are the right spare propellers for your machine without relying on vague marketing language. The crossing blade layout is the defining feature, and the red finish is the only colour stated in the source.

Material and Build

Each propeller is made from plastic, as stated in the product information. Plastic is a common material for small rotor blades because it keeps weight down and can be moulded into the four-blade crossing shape. The source does not give a specific plastic type, flex rating, or impact resistance figure, so no durability claim is made here. What can be said is that the material is plastic, the blades are formed in a crossing configuration, and the set is supplied bagged. Inspect them before fitting and replace any blade that shows cracks or deformation.

Size and Practical Fit

The stated size is 5 inches. That measurement is the key compatibility check when you are buying replacement propellers, because a blade that is too large or too small will not sit correctly on the frame. The source does not list pitch, bore diameter, shaft size, or mounting hole dimensions, so check your existing propeller against the 5-inch figure before ordering. Each propeller has four blades, and there are two pairs in the pack, giving four propellers in total. The red colour is the only colour option listed.

Uses and Placement

These propellers are intended for crossing machine and quadcopter use, based on the product type and size given. The source lists an applicable age of youth, 15 to 35 years old, which suggests they are aimed at hobby or recreational flyers rather than very young children. Fitting and use should follow the instructions for your specific machine.

Event or Professional Use

For club flying, practice sessions, or race days, having spare propellers in the bag means a damaged blade does not have to end your session. The two-pair pack gives you four propellers, so you can replace one damaged blade and still have spares left. The 5-inch size and four-blade crossing design are the figures to match against your machine. No competition rating, thrust figure, or speed claim is provided in the source, so treat these as replacement parts rather than a performance upgrade.

Everyday Home Use

For casual flying at home, in a park, or on open ground, these propellers serve as straightforward spares. The red colour helps you find a dropped blade and confirm which way a propeller is oriented before fitting. Because the pack contains two pairs, you can keep one set on the machine and one set aside. The source gives no indoor or outdoor performance guidance, so use them in the same conditions and manner as the propellers they replace. Store them in the supplied bag to keep the set together.

Benefits and Buying Value

The practical value here is having spare blades on hand in a single pack. Instead of ordering one propeller at a time, you get two pairs, which covers a full quadcopter set with one pair left over as backup. The facts are limited but clear: 5-inch size, four blades, plastic, red, bagged, two pairs. That is the basis for judging whether this set suits your needs.

Reuse and Low Maintenance

Propellers are wear items, and keeping a spare set means you can swap out a damaged blade quickly rather than waiting for a replacement to arrive. The source does not describe a maintenance schedule or cleaning method, so keep it simple: inspect the blades before each use, check for cracks or bends, and replace any propeller that is damaged. Wipe them clean if needed. Store them in the bag provided so the set stays together and the blades are protected from knocks.

Why Choose This Product

Choose this set if you need 5-inch four-blade crossing machine propellers in red and want two pairs in one purchase. The listing gives the essential facts without exaggeration: plastic material, bagged packing, four propellers in total, and an applicable age of 15 to 35. No pitch, thrust, weight, or motor compatibility data is supplied, so match the 5-inch size and four-blade format to your machine before ordering. If those figures fit your setup, this pack gives you a spare pair and a straightforward replacement option.
