This is a light weight cooling equipment for walkera 4G6. After installation, it allow safe running on full throttle curve with stock motor. Also, it allow longer flight times and easy DIY. You can even touch the motor with your hands right after the flight.
From the video, you can see that the 4g6 motor is able to be touched even after a 5 minutes flight on full throttle.
Here I found an innovative guy,timewrex who put efforts on modifying his 4G6, from wingtip to tail rotor blade. Here is how he mods the blade to increase its efficiency and survivability after crash.
He stated this mod is intended to be removable and Replaceable. On average, it takes 5 crashes before the paper tips affect performance.
Good quality white glue such as ‘Elmer’s Glue All’ should be used, as it offers strong enough bonding to the paper, carbon core, and foam. Other glues will make it difficult when remove, and it will leave an irremovable residue on the carbon core and may melt the foam. White glue forms a very strong bond while stay easy to clean it after all.
To remove damaged paper tip, cut a slit in the paper parallel to the carbon core. Avoid cutting the foam or the carbon core. Then tear the paper tip off.
Finally, cut another tip from the template and apply to the blade following steps 6 to 11 in the instructions below. Then you will have a brand-new looking blade, which is still performing as good as when it out of the box, that cost almost nothing to repair! Enjoy!
