FAQ Frequently Asked Questions is a good source of information. When customers call with questions that another customer has asked, we add it to the FAQ page so others can easily access the information needed to get back to the task at hand. If you don't see what you are looking for here, please take a look at our " Support " page or, you can visit our " Contact " page and drop us a line. Thank you. Does the Robart website reflect Live Inventory? We do not. We understand that not all modellers have the ability to go into a local hobby shop and purchase their items so, in an effort to make as much Robart Gear & Accessories available to all modellers, Robart sells direct approximately 3,000 of the 10,000 items we manufacture. Our website shows all these items but due to the constant larger distributor orders we are not able to keep live inventory numbers online. If the item number you are looking at says in stock, this means this item is an item that we sell a lot of and we DO try to keep it in stock but occasionally we do run out. If the item says "OUT OF STOCK", this means that this is only made to order. We do this because we want every modeller to have the opportunity to order exactly what they want but, because it is a very rarely ordered item, we cant manufacture and stock the item knowing it will not only take up shelf space but will also cause price increases due to wasted material and available material for regularly stocked items. If you would like to know if an item is available, please CLICK H ERE and use the form to drop us a line. Please include the Robart Item # and quantity of what you need. You can also contact us at 630-584-7616 for additional support. ​ Example: One pair of Item #150 (Large Rotating Retracts) would be "1 - #150", even though a pair come in a box, since you only need one pair. ​ How much air pressure do I need in the air system to operate retracts? Normal operating pressure is between 80 psi. - 110 psi. After checking pressure and gear, if your system is still not working properly you may need more air volume. Adding a larger air tank or a second air tank may cure the issue. What kind of lubrication do I use in the air system components? Use white lithium or silicone grease only. Using other oils or types of grease will destroy the “o”-rings in the air system and void the warranty. There are only 2 components of the Air System that will need further lubrication: 1. retract mechanism air cylinder “o”-rings, and 2. air control valve “o”-rings. Can I buy individual replacement parts for my Robart Retracts or RoboStruts? Yes, Robart sells replacement parts for all of its products. CLICK HERE for a list of all Robart available Spare Parts. Please note. If you aren't able to locate your spare part, please CLICK HERE to ensure that you have a current list. If you know your part number you can also use the Robart Search Bar located in the top right on every Robart Page. Simply type in the Robart Part number and press enter. Occasionally spare parts are remade and the old spare part number becomes obsolete. The replacement part which can be found on our updated spare parts list will still fit your gear. It was likely redesigned to either accommodate more items or improve with new technology. ​ If you have an older version of our spare parts list, you may have trouble locating it on our website. When searching for a part, if the list you have contains a dash (-), try omitting the dash and searching again. The dashes have been removed on 99% of our spare parts to eliminate the confusion as some items did contain a dash and others did not. EXAMPLE: CUB-017P should be CUB017P How do I diagnose an air leak in my air system or retracts? In our website under “Sup port” , there is a troubleshooting guide on how to diagnose air leaks. You can also download our troubleshooting PDF he re . How do I send my Robart Retracts, RoboStruts, or Air System Components back for repair?

Robart doesn't put item numbers on our parts and accessories because they are used in multiple applications.

Troubleshooting | Electric Control Box The Electric Control Box can sometimes be a little tricky so, we have laid out some simple step by step tasks to help you troubleshoot your item and get you back on track. If you don't see what you are looking for here, please take a look at our " Support " page or, you can visit our " Contact " page and drop us a line. Thank you. To ensure everything is connected properly, we will start with a few standard check. ​ All Robart gear is designed to work on a 7.4V-9V system. Please ensure you are using the correct battery and it is fully charged. If you are using a higher voltage battery, you MUST use a 9V regulator. Make suure the dip switches on the control box are set to the proper setting. Rule of thumb. Unless the gear is tagged with something, set to "B" Make sure you are using all Robart gear and accessories. Using homemade extensions or other brand extensions could cause damaging issues and will void the warranty. Ensure the jumper is properly placed in the auxiliary battery location or, you have an auxiliary battery plugged in. Scroll below to see more about the jumper and its role. ​ Next, lets test the gear to see if you have a bad box or a bad actuator ​ Unplug all gear and make sure the jumper is in place. Plug in one of the gears onto the first port. Follow the instructions to turn this on. If the retract works, following the turn on and off instructions, test the other three ports as well. If it doesn't work, try another gear. If one of you gear is working in all the ports and one is not, you likely have a bad actuator. If all the gear are not working on an individual port, you likely have a bad control box. If none of the gear are working and you are getting a green light, it could be both the gear and the control box. ​ Please use the troubleshooting below as well to help narrow down your testing. What does it mean when I see two blinking red lights? This is an indication that there is an issue with your jumper. The jumper must be in place if you are not using an auxiliary battery. The location of the jumper is the same on both item #177 and item #177-RETRAX . Click on your control box to view this setup. If you lost or misplaced your jumper, you can purchase another one by clicking HERE .

RoboStruts & Wire Kits Robart Gear & Accessories are designed and built by Aircraft Weight .
