My New Favorite FPV Plane // Eachine Flying Fish 🐟
This is a new fpv plane, its actually made by skyzone atom rc. I dont have that version yet, but i believe its going to be exactly the same. So this is a 650 millimeter wingspan plane. 570 millimeters in length its a twin engine, glider style – and you know its very easy to put together, which, actually, surprisingly, did not take me very long to assemble, actually took me longer to put the stickers on because um getting the end pieces on here. Uh is not possible because its a curved surface but thats a thats out of the scope of this video anyway. Basically, all i have to do is put the wing on everything is already pre installed the for this version in terms of the motors and the and the servos and the escs um. Also the um, the control rods and horns are all pre installed. So theres just two screws that are underneath this little cover here, which actually houses the video transmitter, which is a 500 milliwatt uh power, switchable, video transmitter and by the way this is the fpv version. So ive got a fox here, razer nano camera in the front. Here, if you get the plug and play version, you just get the motors and servos installed and everything you dont get the fpv stuff, the camera and the video transmitter. So thats. The only difference between the two versions of plug and play and the fpv version. But the wing just screws on with a screw here and over here you got your.
I think this is the rudder servo, the um elevator servers are in the back. You have these tubes like guide, wires or guide tubes, then that basically keep the control, rod, nice and you know stiff and doesnt, let it flux. So you have good control of the surfaces in the back and theres, also another one for the elevator as well. So the horizontal stabilizer, also just screws in here in the back, all the control horns were pre installed, just um slide the stabilizer in and then use this uh thumb screw to screw that in so thats, really all thats really all took three screws um. You do have to tighten down the elevator control horn and obviously you want to calibrate everything. Theres, like these little screws right in the end, typical of a most of these control rods, is to make sure that its nice and flush when you turn everything on the servos for the control rods for the ailerons were pre calibrated. So there was no adjustment needed there. The two motors are these: like tiny, 1105 style motors, like micro motors 1105, 5000 kb and theyre. Using these three inch, gem fan propellers. Now the way the system works um for the uh two one. I guess they call it a two on esc, so theres, actually a board on the underside of the wing, which i thought was a flight controller, but its not its just a two in one esc.
That has basically both ecs on a single board for both motors, and then it has a uh, basically a servo servo connector that comes off of the board, one for throttle and one for the aileron controls for the two servos and um. The two two motor throttles are actually linked together into one signal unit. If you want to do differential thrust and that kind of stuff, you can separate those into separate control links or to separate channels, but right right now, the way its actually set up its just one channel and, of course, your servo connectors from the rear servos. For the uh elevator and rudder, they come through the from the back here on the inside and then you just plug that all to your receiver, so im using the new matec express lrs pwm receiver. So this is an all in one express lrs receiver that has um these. Basically, these pins and this little board put a picture up here. What it looks like – and that basically is so basically has a five pwm outputs, so you can control everything on the plane and then i have the antenna, the receiver coming out of this hole in the bottom here, as you can see there, i also have a Tape to the bottom of the fuselage all right, so this is what the bottom of the wing looks like theres, a small nub right. There thats for the cg, this isnt documented in the manual the manuals really basic, um yeah for most people that have built planes before its going to be really easy to figure this out.
In fact, i didnt even read the manual, but for beginners it might be a little bit challenging. So if you have questions – and i put this together – let me know in the comments below so you get these uh 4.3 gram, digital servos control rods. Now, of course, all theres, four of them on this plane, one for each aileron and rudder and elevator, so the canopy is held in by magnet. You get a spear canopy like this and theres the magnet there, and i think this is for like a hd camera, or something like that. If you want to like, maybe against 360, go to uh its going to be for the cg is going to be fairly weight sensitive, so i dont know how fusible that would be. I added a piece of tape here to like a basically like that, so i can pull up this canopy a little bit there a little bit easier and then im using a 3s 550 battery in here and the cg is just about right, although its still a Little bit tail heavy according to the cg nubs, it works with the fly and make adjustments as needed, theyre recommending a 3s 750 which might be a little bit heavier. My battery this one here weighs about four things. Like 50 grams, i believe, might need a little bit more weight uh. Maybe if you had an hd camera that and uh, maybe a smaller battery.
That could be something ill make. This balance out right well find out here and shortly when i go take it for a flight, but the battery compartment is pretty. I dont know its not super wide. Its a very you know narrow, thin fuselage. So i had a little bit of trouble figuring out which battery to use a lot of my batteries are a little too tall or too fat, not long enough, etc and again, theyre recommending a 3s 750, but they didnt specify the exact weight. And, of course, you can adjust the battery up forwards and backwards to adjust. Your cg so well have to see how this does when we actually take off our flags. Some of these planes can be very cg, sensitive, so um. Another thing you know before i mentioned, like you, know the board thats in there i thought it was a flight controller, but its just a 2 1 esc, so theres, no stabilization, no gyro on this, so its basically all manual flight, no self level mode. Nothing like that, so, if youre looking for a beginner plane to learn on this might not be the best plan for you, because theres no, absolutely no help. You have to basically set up your radio. You know its a basic radio setup, basically its aileron elevator throttle and rudder, so ailerons channel one um, elevators channel two throttle is channel three and then rudders channel four thats, how i plugged everything into the receiver and everything works out for my radio.
Of course, your radio might be a little bit different um if you are having trouble finding videos on how to do radio subs, for you know, basically a standard rc plane, which is probably tens of thousands of videos already out there. Let me know in the comments below and ill try and help you out. Okay, lets go, take something there and give a fly all right. So getting this to balance on the scale is pretty tricky, but its around 220 grams, all of weight with the 553s and uh yeah, not including the tape there. I i teared that off thats around 228 222 grams there theyre targeting the sub 250. So, with a 750 milliamp hour battery that theyre recommending which i think you can probably put in there, if you put it way back, um its probably gon na get close to the 250 or just a bit under, depending on the weight of your battery but yeah. If youre looking for sub 250 fpv plane with the battery and the fpv stuff on there, no hd camera, this plane might be the one youre looking for all right. So im not sure how this is going to launch no stabilizer. So im, not sure. If i can do fpv today, i might uh show this ill probably show this video but im going to probably do this on another day after another days. I have to find a way or figure out a way to launch it and get the goggles on, because it doesnt have a stabilizer so its not going to apply by itself.
Okay lets uh go ahead and take it off. It looks tail heavy, so i dont have enough battery in there, even though i have it balanced on the cg points, all right so pretty calm day today. Well, uh get this up in the air. Uh do a little line of sight and then uh right to fpv, so theres no stabilizer on here, oh too low, so yeah its a little tiny bit tail heavy. So i didnt move up to a 650., its a little squirrely. I think i got to reduce my rates a little bit here, so im gon na bring it in all right, so i think im gon na go ahead and just fpv it right now. Okay, so basically, this plane flies fairly well, it does fly with a high cruising speed and uh they advertised in the product, um page thats about 20 kilometers per hour thats about right, so uh. You need a larger area to fly. This end, where im versus, where im flying it now, so i am actually going to put a stabilizer on this and find a larger place to fly this um, because just going around circles like this is kind of boring, uh, maybe also another day where the lighting Is a little bit better, but lately the weather has been just crappy, um yeah for california. This is really bad cloudy every day like this, so not very interesting, but this plane for fpv, i think, really needs a stabilizer and im going to see.
If i can put the one from zoe hd on here, i think its called the copilot its going to be a really tight fit to get all that stuff in here. I think thats. One of the issues with this plane is that its not enough space for all the stuff you want to do for fpv, but you want to try and keep the weight under 250 grams, so theres, obviously that big trade off and try and find the right battery For this is also going to be a challenge because im still a little bit tail heavy here anyway, i was gon na. Do it for this first video im gon na have another one this one. This is its actually a good plane.
