When I bench test my gear they work great but they wont retract into the plane when I'm in flight? BINDING Binding is one of the most common causes of retracts working during bench testing but not during flight. There are several ways this can happen and we will work through each of them here so you can test your gear. Binding - #1 When you put a tire on a car, you never tighten down the lug nuts in a circle. You always go opposite from the one you tightened last and than cross and opposite and then repeat. The same goes for your retracts. If you tighten down one side more than they other, this will result in the retracts becoming off center and restrict its ability to fully retract in the closed position. ​ Binding - #2 Another form of binding is when the kit is built too tight. When a plane is taking off or landing, there is a wind force that pushes up or down on the wings. Click here for a rendering of this . To simulate this process you can place your kits wings onto two secure surfaces, like THIS . This will help show you if your kit will bind around your retracts, wheels or other areas by pushing up or down simultaneously on the wing tips as if it is actually flying. This technique can be used right side up or upside down depending on the direction of travel you wish to test. ​ Binding - #3 (Electric) When I get a new toy, you can find me playing with it over and over again to see if it works but also, because its new and that's why I got it. With electric retracts, this can actually cause them to bind. Every time you power on your retracts, there is a slight power surge to the system. And although this wont hurt the system, it can cause the retracts to turn ever so slightly. And, sometimes it's so little you cant even see it when you're starring right at it. This can cause the retract to "over-tighten" or bind in its current location. And, since our system is designed to shut off when it hits resistance to help protect itself this type of binding can make your gear appear to be inoperable. ​ You will notice on the back of the actuator there is a jack screw. This is what needs to be loosened to remove the built up pressure. ​ Simply remove the screw holding the front of the actuator in place. Using your hands, unwind the actuator to relieve the built up pressure. Reinstall the screw and you should be back flying in no time. CLICK HERE FOR A VISUAL GUIDE.

Phonetic Alphabet NATO Phonetic Alphabet The NATO phonetic alphabet is a Spelling Alphabet, a set of words used instead of letters in oral communication (i.e. over the phone or military radio). Each word ("code word") stands for its initial letter (alphabetical "symbol"). The 26 code words in the NATO phonetic alphabet are assigned to the 26 letters of the English alphabet in alphabetical order. ​ Each word is chosen because it CANNOT be confused for any other word when said, hence the reason it is used to help people spell words over phones or radio. It began with the introduction of voice-communication over radio signals. ​ Sometimes you will hear someone use the word "Apple" instead of "Alpha". In the English language alone, there are 43 other words that sound just like apple. out of those 43, over half of them also sound like other words starting with other letters. This is why using the correct Phonetic Alphabet is so important. Robart Customer Service is made up of military veterans, military families and former pilots and we are well versed in this alphabet. Feel free to use the guide below when contacting us and we will do the same. Help get you what you need the first time.
