I've always been a big believer in you get what you pay for but today I was proven wrong. I've a full set of 15x5 t-motor propellors and they were a real pig to balance. It was mainly the hubs that were off which took the best part of a day to balance by grinding the heavier side and using glue on the lighter side.

However, I bought a set of these. For a fifth of the price the quality is far superior. Hubs are balanced and only a tiny amount of sellotape to balance to blades. They fit the t-motors perfectly, no boring the holes like some cheap quanum ones I had previously.

If your looking for props you can't go wrong with these.

Very nice props taking into consideration the price. they need a bit of balancing but not a big thing. I'm using it with my DJI 320kv motors - to fit them I needed to grind central part because they are to broad. Overall I recommend them as replacement of original CF props for DJI S800.

I mounted these on my Hexacopter of 4Kg AUW. They hover well around 45pcnt throttle on 490kv motors and 4S setup.
Couple of them needed little balancing using dubro balancer. Build quality is sturdy. Overall best quality propellers, I believe there is no need to buy anything expensive, they are at par with much low price

These props are fantastic! I bought them to be used in conjunction with the Turnigy Multstar -480KV motors. The props are solid carbon fiber weave, not foam-filled laminated with the weave. They are extremely light yet stiff for their size. The construction quality is pretty good, not the best, but for the price? Unbeatable! I would highly recommend them to anyone interested in a great value!

These must be balanced before use. The 3 sets I have needed 2 or 3 100mm lengths of Sellotape "Diamond tape" on the back of the light blade. They are also too wide at the hub for the earlier style of top retaining plate ( it has 2 overhanging shoulders) of the Multistar 320 kv motors that I have. ( the new stock of this motor is different in the picture and I suspect would be no problem. Still yet to run on my hex though)

How to DIY and Replace 15 x propeller

Replacing a 15 x propeller is a straightforward process that can be done with some basic tools and mechanical knowledge. Here is a step-by-step guide on how to replace a 15 x propeller:

• Gather the necessary tools: Before starting the replacement, make sure to have the following tools on hand: New 15 x propeller, propeller wrench or socket, grease, marine-grade anti-corrosion spray, safety glasses, work gloves, and clean rags.
• Prepare the work area: Work in a well-ventilated area with enough space to maneuver around the boat. Ensure the boat is securely placed on the trailer or dry dock.
• Safety first: Wear safety glasses and work gloves to protect against potential hazards. Ensure the boat's engine is turned off, and the kill switch is engaged to prevent accidental propeller rotation.
• Remove the old propeller: Use a propeller wrench or socket to loosen and remove the nut holding the old propeller. Depending on the setup, this may require some force. Carefully slide the propeller off the shaft, taking care not to damage any surrounding components.
• Prepare the new propeller: Before installing the new 15 x propeller, apply a thin layer of marine-grade grease to the shaft. This will help prevent corrosion and make future removal easier. Inspect the new propeller for any manufacturing debris or residue and clean it with a clean rag.
• Install the new propeller: Align the propeller's keyway (a small groove) with the key on the shaft. Slide the propeller onto the shaft until it is firmly against the bearing or housing. Use the propeller wrench or socket to tighten the nut securely. Be cautious not to overtighten, as this can damage the shaft or the propeller.
• Check the alignment: Ensure the propeller is properly aligned with the drive shaft and is parallel to the hull. Misalignment can cause vibrations and reduce efficiency.
• Test the boat: Before taking the boat out on the water, perform a quick test of the engine to ensure it runs smoothly with the new propeller. Engage the engine briefly while the boat is still secured. Listen for any unusual noises, vibrations, or issues with the propeller installation.

Once satisfied with the propeller installation and alignment, unchain the boat from the trailer or dry dock and prepare to launch it into the water. Be sure to follow all safety and environmental regulations during the launch process.
