X8 Setup and Pre-Flight

this is max Messinger a tool in aerospace and I’m here today to show you how to assemble and preflight the x8 flying wing aircraft it’s a pretty simple process and if you follow the instruction manual and the checklist it’s pretty straightforward but I’m gonna walk you through it here just so you can see so the first step in getting this thing ready to fly is to take our wing spars you get two of them in the kit one is long and one is short the long one is going to slide through the back hole right here it’s normal for them to be some friction in there and then the front bar is going to go through now when you put this front spar through it actually goes through the inside of the fuselage so watch and make sure that you’re not pulling any wires out with that and then it’ll just go right over into the hole on the other side of the fuselage and we end up with it looking about like that now we’re ready to put on one of our wings so I’ll start with the right wing so we’re just gonna take this and put our spars into the holes on here and now we have these wing joining pieces these clips right here we want to slide all of these forward because you can see here when it slides to the back it’s gonna close over this piece on the other side so we’ll slide these forwards so they’re open and we’re gonna take our servo wire and there’s a little cut right here just in front of the rear wing spar and we’re just gonna put our servo wire through there and then we reach inside and pull it out through the other side and now as I slide the wing on you’re gonna see how that’s going to kind of bunch up so I’m gonna pull on the servo wire gently while I slide the wing in there and then we just go ahead and push it all the way home and then once it’s joined up we can put our clips clipart slide our clips back and then this servo wire is going to attach to this wire that’s clipped right here beside the autopilot so we’ll just look and we’ve got white to white and then we’ll just tuck this away inside the fuselage this other lead is gonna is for the other wing servo so we just repeat the same process over here slide our clips forward put our servo wire through keep a little bit of tension on the inside and slide the wing all the way home and slide our clips back and then we’ve got our other extension plug those in make sure it’s seated all the way and then we can just tuck this in there beside the autopilot so now the aircraft is all assembled so that’s good to go we’re going to go ahead and place our batteries so if you’re flying with the camera battery placement is really simple one of these batteries is going to go all the way up to the front and if you look inside there there’s velcro all the way up at the front of the nose and there’s velcro on the ends of these batteries so that velcro it’s gonna go all the way to the front stick on the nose there and then press the battery

down to seat it to the battery tray make sure that’s nice and secure and in this other battery you’ll notice that both of them have also have velcro on the side that is for this strip right here so the battery is going to go in here and make sure we’re not pinching any wires or anything like that and we’re gonna slide this forward and seat it down so that it’s velcro to the front and the bottom and that should be it’s gonna have a little bit of play in it but it should be good and secure it’s not going to go anywhere so then at this point all of that’s put together we would be ready to power it up so we will go ahead and switch over to our operation checklist so I have this printed out I recommend that you always take this with you to the field when you’re going to fly the top of it is mission planning so you’ll use this when you’re setting up your flight plan and then we have our pre-flight checklist so step one we’re going to assemble the aircraft we’ve already taken care of that step two we’re going to make sure that our winglets are securely attached and don’t move so the beginning of this checklist is all structural checks so we’re just going to kind of gently manipulate those there’s gonna be some flex but we want to make sure that they’re not loose then three we’re gonna ensure that the elephant’s are securely attached to the wings and all of our servo control hardware is securely attached so we’re going to make sure that our tape here that forms our hinge is good we’re gonna make sure that these linkages are all tight that this control horn is tight on there that the servo horn is tight and that this rod doesn’t move through this linkage that that’s tightened down and we’re gonna do this for both sides needless to say these two surfaces right here provide all of the control for the aircraft if one of them too were to fail the aircraft will crash you cannot fly flying away long so be sure to do that check before you fly we’re going to confirm that the motor mount is secure and that the motor is secure on the motor mount so we’re going to make sure that our motor mount isn’t loose in the frame and we’re going to make sure that our motor is not loose on the motor mount and then we’re gonna make sure that the propeller is tight on the prop shaft so we’re just going to grab the motor can and move the propeller or try to move the propeller and confirm that everything there is tight okay we’re going to make sure that all of our electrical connections from the battery to the motor look good so we can look back inside the fuselage and back at the rear of the fuselage where those three wires go through that hole there’s three connectors you basically shouldn’t see any exposed metal there you may see a tiny less than a millimeter of exposed metal but any more than that and those connectors are loose and you can just slide them back together and then we also want to make sure that this connection down in there is tight okay now we’re ready to start powering things up so we’re going to power up our transmitter Taranis touch warning now we’ve got a switch warning that means that one of these switches is not in their off position and right here it’s telling us it’s switch F which is right back here when we flip that back we’re going to get our normal startup screen you may get a switch warning or a throttle warning if the throttle is not at the minimum so all you have to do is make sure the throttle is down and make sure all of the switches are up away from you okay now we’re ready to power on the aircraft so we have two battery leads here one for each battery these just go these are called T connectors so

we’re just gonna plug that in there and we’re gonna get a series of sounds that musical tone at the beginning was our autopilot booting up this movement on the Left Elavon is indicating that’s a servo demonstration that’s showing you that the output from the air from the autopilot is functioning and then there were some beats that came out of the motor and those are showing us that our motor controller and our motor are functioning properly so now we’ll get our second battery and connect it up once you be careful because once you’ve connected one of these batteries these are exposed leads that are live so if you were to touch these against metal they would short out the other battery so make sure that you connect up this second lead as soon as you can and don’t let it touch any metal in or around the aircraft so now our our battery cables are hooked up so that everything is powered up now we are going to connect mission planner so I’ve got our computer here and I have our telemetry radio plugged into our USB port we have a solid green light and a right and irregularly flashing red light you may not be able to see the red light it’s kind of dim but our solid green light means that this radio is linked so if we were to look at the radio modem inside the plane it would also have a solid green light if this green light is flashing slowly that means that there is not a link that this is not finding another radio so we have that solid green light we’ll go ahead and click connect no change to stop allies and if you have an issue with it connecting change to stop I can try restarting either the ground modem or restarting the aircraft no change to stop with eyes okay there we go so I unplugged our ground modem plugged it back in now we’re connecting up okay okay so we’re connect to the aircraft and we have a GPS fix there so our next step is if we were actually out flying we would load a flight plan we would read that flight plan back just like I showed you in the mission planner tutorial and then now we’re ready to do the rest of our pre-flight checks so with the aircraft in manual mode which like we learned before is is indicated on our heads up display here so with the aircraft in manual mode no change to FB wh-which now we are in maintain manual we’re going to check all of our control surfaces so I’m gonna push to the left and my roll stick and when I push to the left the left wings elbow should come out and the right wings elevon should go down so this is pushing the right wing up pushing the left wing down which is going to cause the left row if I push to the right you should get exactly the opposite if I pull back both should go up which is going to cause the nose of the aircraft to climb if I push down a push forward it’s going to push the elbows down causing the nose to drop this is counterintuitive to some people but this is after the yoke on a regular airplane so when you pull back your nose that’s gonna go up and when you push forward your nose is going to go down okay now we will do our fly-by-wire check so we’ll move our mode switch on the controller to the cinema position with

that in the center position we’re in F BWA that’s confirmed by our computer and now we want to confirm that the stabilization is working correctly so the way we do that is to manipulate the aircraft so if I pick the aircraft up and I roll the aircraft to the left I should get control that’s going to roll it right so counteracting this left roll so you can see that my right Elavon is up my left Elavon is down which is going to return the aircraft to a neutral pit to a neutral roller and if I roll to the right I get exactly the opposite if I pitch the aircraft up I get the elephant’s pointing down and if I pitch the aircraft down I get the L ones coming up so all of our stabilization is working properly so we’ll set our flight mode back to manual and at this time if we were out flying and we had a camera we would place the camera right in here the camera handle on the right side is going to stick right here the bottom of the camera is going to stick right here and this led for our sony cameras is going to go right here in front of the infrared control receiver on the camera and then we will power the camera up set it into shutter priority mode with a shutter speed of 1 over 800 and an ISO setting on it so with that done we will secure our hatch okay and then our last step before we’re ready to fly is to confirm that the aircraft arms and that the motor spins properly so there’s two ways we can arm the aircraft I showed you one in mission planner which is to click the arm disarm button the other way is with this throttle stick we can with it fully at the minimum we can press it over to the right and hold it and let it return to the center and we hear that long beep indicating that the motor is armed the computer talks to us and confirms that this is not something I recommend doing inside because this prop can spin up quite fast and cause some damage let’s wait up yeah if you click on the HUD it pops it out fullscreen on the hood yeah okay so start right from there yeah so to arm the aircraft from the to arm the aircraft from the transmitter we’re going to with this throttle stick all the way down push to the right and hold until we get that long beep and the computer tells us that the throttle is armed once we have that beep any movement of this throttle stick is going to cause the motor to spin so be very careful of that so if I move this stick forward a few clicks the motor spins so that’s all we want to check for we want to see that the motor spins and stops and at this point if we were out at the

field the plane would already be sitting on the launcher we would go ahead and tension the bungee we would hook the launch hook to the bottom and we would be ready to go so that’s it thanks
