|sequencing, is provided by a small LED mounted on the heli frame shining toward small optical sensors that are buried in each blade. Programming the internal chip is accomplished through the same charging port mentioned above using a Jeti programming box. The instructions are a little sparse in this area due in part to the translation to English, but the process is easy enough to work through. In total you have five different patterns including circles, a smiley face, dashes, and a sunburst. I find the concentric circles provide the best orientation for flight. Textually, short words or messages can be flashed intermittently on a programmable cycle if you’re inclined. This would be perfect for night air shows or even a marriage proposal for the really hardcore rotor nuts! There are a couple of areas of concern that could be overlooked. First, the cells used in each blade are LiPo’s, so you want to be careful to avoid over-discharging the cells. This is unlikely in flight, but could occur if you forget to unplug them after flying. If damaged, the cells can’t be replaced so be careful. Also, the Jeti programming box and blades can handle no more than 5 volts as a power source. Any more can cause damage to the blades.
Although I was a little hesitant to try out my new Trex 600 at night, I found the experience to be really fun! The lighting patterns provide more than adequate orientation, casting enough light downward to clearly highlight the canopy and tail boom. If you need additional orientation cues, lighted tail rotor blades are also available for some sizes of helis. Overall, this is an excellent product that is well thought out and implemented. With some care, however, your new blades will provide many hours of night flying fun!
