Unpacking Threadlocker: Purpose and Benefits

Threadlocker, synonymous with the brand name Loctite, stands as a cornerstone in the assembly of FPV drones, particularly for anchoring metal threaded fasteners. Its primary function is to prevent these components from loosening due to the rigorous vibrations during flight. With a consistency that mirrors oil or paint, Threadlocker demands a substantial period for drying and curing upon application. You can use 8000KV brushless motormeps motor19000KV brushless motor.

It is worth noting that the application of Threadlocker might be unnecessary when using a nyloc nut. The integrated nylon insert within the nyloc nut is designed to lock the bolt and nut tightly, making the use of Threadlocker superfluous in such instances.

Guidelines for Applying Threadlocker

It's not uncommon to receive drone parts pre-treated with Threadlocker, recognizable by a blue residue on the threads. If your components are not pre-treated, applying Threadlocker yourself is straightforward and economical. A single small bottle can be surprisingly enduring, potentially serving your needs for years.

Application Steps

  1. Initial Setup: Lightly pour a small quantity of Threadlocker into a tray. Only a slight amount is needed.
  2. Preparation of Screws: Cleanliness is key. Use a paper towel to clean the threads of the screws, ensuring removal of any grease or dust. While traces of grease aren't typically problematic, cleaner threads are ideal for the application.
  3. Applying the Threadlocker: Carefully dip the tip of the screw into the Threadlocker. It's crucial to avoid applying too much, as it could complicate the removal process later on. Conversely, applying too little might not secure the screw adequately. Any excess can be wiped away.
  4. Screw Installation: With the Threadlocker applied, proceed to install the screw. The compound will harden, securing the screw in place. It's advisable to allow the Threadlocker to dry for several hours, ideally overnight, for best results.

Tips for Removing Screws with Threadlocker

In cases where too much Threadlocker has been applied, removing the screws can prove challenging. If a screw is particularly stubborn, gently applying heat with a soldering iron for a few seconds can help loosen it. This process may need to be repeated as necessary.

Cautions and Best Practices

Threadlocker is specifically intended for use with metal materials and is not suitable for plastic, nylon, or wood. Although many modern nylon and quadcopter parts tolerate Threadlocker well, some plastics may not react well to it. Thus, its application on plastic threads is discouraged.

Furthermore, applying Threadlocker directly to the motor shaft should be avoided, as it could damage the propeller hub's plastic, risking weakening or breakage. In most cases, a nyloc nut can effectively prevent propellers from becoming loose without the need for Threadlocker.

Following these comprehensive steps ensures that your FPV drone is assembled with the utmost attention to detail, leading to improved stability and performance during flight.
