Rotortech luminous series of 3D night blades for 50 size helis are built by the same factory that makes (those) top branded blades you see rebranded in the USA and UK..
These blades are switched on by centrifugal force, so you dont need a switch or plug to turn them on/off and wont waste battery power when landed. The battery comes seperate and fits securely inside the blade grip so you can have several battery packs for the night or replace the battery easily should it become faulty. Traditional night blades would require a complete replacement if one battery was faulty or low on capacity.
You wont find a higher quality set of night-blades anywhere.

Absolutely AMAZING blades. I bought these for my HK600 and they are the first real high quality blades i have bought. I was floored when i saw the quality of finish and the overall blade quality. These are well worth the price IMO, even considering that you have to buy the battery pack and charger. Very bright as well. If I ever crash these i will buy them again.Great night blades very stiff and bright great for orientation due to different colored rings top and bottom batteries have not needed a charge in 4 flights so far. Highly recommend these night blades over my old align night blades.geniales Spielzeug fuer die Nacht...
