4S 1000 35C Zippy Compact battery
Turnigy D2826/6 2200kv motor
30 amp Turnigy Plush ESC
Two Emax ES08MA II servos
6x4 APC style Hobbyking prop
Lemon DSM2 receiver
Modifications:
LED Lights
Zip-tie landing gear skids.
Ailerons adjusted as low as possible for flaps effect helps provide drag and lift during high alpha slow flying.
Elevator trimmed slightly upward.
4S battery is a must for this setup. 3S provides enough power for hand launches. 4S provides enough thrust to overcome drag on the landing gear skids during take off.
Excellent value. Very stable. Flies great. Low cost. High fun factor.
What a simple solution for a big problem. I salute u sir.
so we can only buy the KIT, the building is done by us?
so in that scenario how do we build?
does it come redimate?
this is my first time in the rc plane world, please help me with some guidance
I love those builts putting a few of them together myself
Awesome 👌🏼
Beautiful plane and a good pilot.. saw your aeleron seting a little downward right.. what its for sir..? Mine will be setting like yours 😊
Thanks. I’ve found that setting the ailerons a little bit downward provides slightly more lift at slower speeds, similar to flaps. Some refer to these as flaperons (flaps/ailerons combined). It’s achieved mechanically by moving the servo horn one tooth forward on the servo cog.
@@2fly4awifi87 thats explain a lot.. will try that setting a little bit.. and start from there 👍🏻
@@2fly4awifi87 How about the aeleron and elevator throw setting? Also the expo setting.. Btw that Zipties landing gear are Brilliant
@@zayyandzikraka3833 I prefer 50% throw with 35% expo on the ailerons and 125% throw and 35% expo on the elevator.
I got a question brother. The foam that's used for that Jet. Do you know if it's EPP foam. Will it tear like Dollar Tree foam board. Also will tape stick to it for reinforcement. I want to build that Jet, but I won't if the foam isn't durable.
I’m not sure what type of foam it is, but it’s much more durable than dollar tree foam. Unlike dollar tree foam, there is no paper coating on this, rather it’s a more rigid material all the way through that’d be difficult to tear with bare hands. Tape does not stick well to this foam. Hot glue is the best adhesive for it, but use it sparingly to minimize the overall flying weight.
Awesome plane and flight!
Will definitely try this motor combo on my next glue-n-go, thanks for the video!
Thanks Kenneth Kiser, this motor combo is a rock solid powerhouse! I've used it on over a dozen planes during the past five years. With a light 4S 1000 battery the 30 amp ESC pairs well with either a 6x4 prop or a 5.5x4.5 prop. It can high-alpha the plane on it's tail and then throttle straight up until it's barely visible. Flight times are approximately 3 minutes pegged at full throttle and about 5 minutes of mixed/easy flying. Less than half throttle is enough to maintain a consistent altitude for 5 minutes of relaxed flying.
I've got the J-20 and SU-27 ready to be built, just waiting for the time. I went with a miniquad motor, the Gemfan RT2205L 2300 kv spinning a Gemfan 5040 prop, and a Plush 30A ESC on a 4S 1300mAh nano-tech. With the wattage difference, I'm worried I might have picked a power setup that'll be too fast for my park! The motor color will go great with the F-35 color scheme if I can get my hands on one.
Kenneth Kiser, your setup sounds fine. I don't think it'll be too much. The extra power is great for the launches. I like to get mine up high, do a few loops, and then adjust the throttle down to the minimum needed for steady flight. It glides really well.
Ailerons setup as low as possible and elevator trimmed slighly upward is set when the stick at center position, isn't it?
Yes, center position on the stick should should include elevator slightly up and ailerons slightly down for more lift, like flaps, but not as low as possible. Why not? Because when you move the stick to the left and right you still want the ailerons to move both up and down to provide the maximum left and right steering control. If aileron is already all the way down it can not travel further down so the plane would have to rely on the other aileron only. You want both ailerons to roll the airplane left and right. Once the wings have rolled left or right, using up elevator will complete the turn. We call that “bank and yank.” Bank left or right, and yank up elevator to turn. That’s how the airplane turns without a rudder. Hope this helps.
@@2fly4awifi87 thanks for yr explanation, that's clear...but if any youtube link regarding this setup, it will be much much greater...thanks anyway
@@DONSOEL th-cam.com/video/xToLy9Yex-E/w-d-xo.html
@@2fly4awifi87 that's great..however is it ok if i use battery 2200 mah 30c 3s instead of 1000 mah 4s 35c as you used with other components remain the same?
@@DONSOEL I’ve done that… one flies like a jet and the other flies like a tank.
Brilliant! I'd toyed with the thought of zip ties for tricycle landing gear but never seen it as well-realized as this (I didn't think of doubling/tripling them like you have.) Two things I'm dying to know are: (1) AUW with the setup you posted above, and (2) have you ever tried a roll-off takeoff from short grass? If so, how did it go?
Thanks! AUW is 16 ounces or approx 454 grams. It probably would not take off on short grass, but hand launching this plane is super easy.
Nice job, great tip to use the cable ties. I'm yet to maiden, did you use the recommended 75mm CG or 85mm as pilots are stating. Also roughly your throws? I've included rudders.
Thanks
Thanks. The CG on mine is 40mm forward of the motor where it attaches to the motor mount. The throws, measured up and down at the back edge of the elevator, are as follows. Elevator throws are 25mm up and 25mm down. Aileron throws (again measured at the back of the elevator) are 20mm up and 20mm down. Expo for both the aileron and elevator is 35%.
2FLY4AWIFI Thanks for the info, I have the Mig29 so obviously different CG. Maiden this weekend with installed cable ties. 👌
I also have the Mig29. It flies better with CG at 85mm. I've got the throws set to 20mm up and 20mm down for both the elevator and ailerons.
2FLY4AWIFI Awesome!! I'll see how she flies and will add expo as required. Using a HK Funfighter 1950kv on 4S 1300 6x4 carbon prop.
That’s a great setup. I’ve used that funfighter motor on 4S with both a 6x4 and a 5.5x4.5 on other planes. Perfect thrust to weight ratio.
OK, Guys! I bought them all...! The SU-27, Su-29, J-20, F-35, Arctic Cat, and the Prime Jet-Pro, from Hobby King. Waiting on motors and ESCs for now!
It seems like a great "DEAL for the Money", as I got all of those on sale! I really like those Wire Ties for landing/takeoff skids (who wudda thunk?). Haha!
Wish me luck (I'm gonna need LOTS of it!)...
Where is "Part 2" of this?

@@2fly4awifi87 That 4-S Bat. sure makes a LOT of difference! Vertical Take Off...! (Also noticed what you did about your "skids", too!).
Thanks, and I hope you know Hobby King has those planes on sale for about the cost of a battery, right now! (Trying to talk myself OUT of buying another one, myself...!) Haha!
Thanks again...
With the great idea using the zipties, would it fly off grass, do you think?
The zip-ties are better for protecting the prop when taking off and landing on pavement. For grass it’s better to hand launch and land on grass with or without zip-ties.
I wanted the su-27 bad. Unfortunately they were out of stock in the US, got the J-20. Tons of fun!
Alex C, yeah, the first run of the SU-27 sold out faster than the other models. HK is likely cranking up production for the next round. I'd like to see some new models in the glue-n-go series, especially a blue angels F-18.
2FLY4AWIFI oh man me too! I had pretty low expectations for $20. Way wrong!
Alex C, yeah, way wrong is right! I did too. Man was I surprised!
Flew the F-35 for its maiden flight, but the recommended center of gravity in the manual (11.5cm in front of the motor) is wrong, which made for a crazy tail-heavy flight. The proper CG for my F-35 is 15.5cm in front of the motor. I'll post an F-35 video as soon as possible.
The recommended CG for the SU-27 is correct.
Might want to move the battery way forward on the J-20 for the maiden flight just to be safe. Better nose heavy than tail heavy.
2FLY4AWIFI I actually have a good 20 flights on my J-20 already. Definitely likes nose heavy, but to be honest it flies great on anything from a 1300mah to 2200mah 3s. I think I'm going with your setup though, I have a bunch of 1000mah 4s batts from my Radjet that would be perfect.
Alex C, thanks, good to know that about the CG on the J-20. Funny that you should mention the (original, lighter) Radjet 800mm. That's the plane that helped me optimize the 4S power setup. The Radjet flies like it's on rails at high speed. So the only difference between the glue-n-go jets versus the Radjet was that I used a 5.5"x4.5" prop for more speed. The setup spins faster with that smaller prop and sounds amazing, like a dentist's drill. I prefer the 6x4 prop on these glue-n-go models for better slow flying. Both props draw a similar number of amps at full throttle (
Good job and thanks for the zip tie mod. I'm -slowly- putting my J-20 fighter together as we speak.
I also put an order the SU-27, but its on back order .
Nice flying *
Thanks Valkyry5. Zip tie update - use 3 layers of zip ties on the front gear and 2 layers of zip ties for each of the two main gears. Still very light and prevents damage to the prop when landing on asphalt. In the video I'd only used 2 zip ties in the front and 1 each on the mains. Eventually the pavement friction wore down one layer of the front gear. Take offs cause more wear than landings.
To add another zip tie over the top, remember to hot glue the ends and the entire length of the zip tie to help it structurally flex as one. After it cools, add a little more glue to the sides.
Front holes are 55mm apart and the bottom of the zip tie extends 55mm down. Main holes in the rear are 60mm apart and the bottom of the zip tie extends 45mm down. The front should be a bit higher.
Aesthetically, the zip ties are barely visible while the plane is in the air. Functionally, they work great.
Valkyry5, very cool, I'll build the J-20 next and am looking forward to seeing how it flies. Just built the F-35 and will add zip tie landing gear before the maiden. The SU-27 looks really good in the air. Not sure if you noticed that HK also has a glue-n-go MIG-29. They didn't include it in the product video, but I ordered it as well.
@@2fly4awifi87 Can you help layering the play this is please
yo quiero comprar uno de esos, donde lo consigo?
Hi
I just got the Arctic cat glue and go , and wondering what the best and readily available glue to use as it needs large amounts of glue
Thanks
PAUL BREITNER Hot glue sticks can get really heavy, but it adheres this foam board really well. Not sure what else is out there. I try to use as little hot glue as possible and scrape away any excess while it’s hot.
Sir can be done universal rc transmitter app is working
Yes. I use a Spektrum DX6e transmitter and a lemon-brand receiver.
Nice build! How much fligh time with this setup and 4S 1000mah?
Thanks. The 4S 1000 provides 3 minutes of fast flight or 5 minutes of slow flight. I use a battery tester, starts at 4.20 volts per cell and finishes near 3.80 volts per cell.
2FLY4AWIFI Thanks for fast answer. Ouch sounds quite short time.
Yes, it’s a short but the lighter battery makes for much better performance. I tried this same setup with a 4S 1800, and I get a few more minutes, but it feels like half the power because of the added weight. Try both and see what you prefer. I prefer the lighter setup. Much more fun.
2FLY4AWIFI OK thanks for the info!
4 x 6 prop? Not a 6x4? Thanks for all the tips though, I can't wait to get mine into the air!
I use a 6x4 prop; 6” diameter, 4” pitch.
Hi. Do you still fly the hking su-27?
It’s been about a year, but it’s still in one piece.
like the skids. just looped zipties? don't they cut thru the foam?
Ghost Rider the zip-ties are half looped and don’t make a full circle. Just make the holes near the edge of the foam with a knife and a flathead screwdriver, add a bunch of hot glue on the hole, and then push the cut ends of the zip-ties in and hold for about a minute until the glue cools. The glue creates a blunt stopper that keeps the zip-tie from piercing through the foam.
thanks! gonna give that a go. love the rolling take offs/landings
Ghost Rider, just make sure the front one is 2cm taller than the mains in the rear, and in part 2 or 3 you’ll see that I layered three zip-ties in the front and two on each of the rear mains. They work great for both takeoffs and landings.
IS IT FANTASTIC, WHAT'S YOUR COST? WHO IS THE MANUFACTURER AND DIRECT DISTRIBUTOR?
JORGE HERNAN ALZATE ARANGO Yes it’s fantastic. $25 USD for the kit + $50 USD for all the parts. Hobby King.

I WOULD LIKE TO BE ABLE TO DISTRIBUTE THESE PRODUCTS FOR COLOMBIA, IT WOULD BE A GOOD MARKET, CAN WE TALK ABOUT THIS BUSINESS?
JORGE HERNAN ALZATE ARANGO contact the manufacturer, Hobby King.
hi there love the plane could you please specify about the motor and prop is it cw or ccw as this is doing my head in about the clockwise and counter clockwise
Hi, by switching any two of the three wires extending from the electronic speed controller (ESC) to the motor will reverse the motor rotation from clockwise and counter clockwise. So it’s okay to buy either rotation prop and switch the wires accordingly during assembly.
Also most motors are non-directional so they can easily run clockwise or counter clockwise. Hope this helps.
@@2fly4awifi87 thanks for the reply and info im more of a glow guy in the rc world and slowly making the transition to electric im getting confused with this as i used to have a glow model that was a pusher and had to get props suitable so thats where im getting all confused so basically all i need is the motor specified and a prop dosent have to be a pusher prop right ??? sorry if im sounding dunse i just dont want the plane to go backwards just cause the motor is facing that way lol so all the help that i can get is well and truely appreciated , cheers and thanks again for the reply 2FLY4AWIFI, and love the name you got - Awesome !
Andrew Reece yeah, I used to wonder the same thing about rotation. Always glad to help. Yes, either CW or CCW props work fine. During assembly when I plug in the three wires I test to see which way the thrust blows, and if the thrust pushes the plane backwards I simply swap any two of the wires, and I’m good to go.
@@2fly4awifi87 cheers bud so glad that u could understand my delema ill see how it all goes when i get the model and bits and will let u know , cheers agian mate.
Can you try using 2s 2800mah and 2450kv motor? Maybe that can flew longer!
You can, but even a 2S 2700 zippy battery has half the voltage of the 4S 1000 and weighs 33% more (160g vs 120g) so you’ll probably need more throttle to keep it flying, which would in turn deplete the battery faster and decrease your flight time. Generally more power is also more fun. I can get 3-4 minute flights going fast with the 4S 1000 or 6-7 minute flights with easy throttle management. Lighter more powerful planes are also easier to maneuver if you get in trouble, but you can try both and see which you prefer. I prefer this performance and take five charged batteries so I can fly longer. IMHO this setup rocks.
@@2fly4awifi87 what about the motor into 2450kv and 2200mah 2s
fj toys aeromodels I’m not sure, but maybe you can try it and see. This airframe is super light, so if that motor/battery combination works well in your other light planes you probably will like it in this one. There’s no right or wrong combination - it’s just personal preference. It’s fun to try it and see for yourself.
@@2fly4awifi87 i want to test it with my WingDragon on 2s 2800mah and 3s 1800mah and see the flight time later. Im already have both battery
fj toys aeromodels that sounds good. Maybe you can post a video of it on your channel and then add a link here.
Hello, do you use a flight controller?
Hello, no I don’t use a flight controller. A friend tried to put one on his recently, but he found that it flies better without one.
hello, is there a motor-battery pair that can fly 10minutes or more? thanks!
For me this is the right motor-battery combination for lots of power and the light weight makes it lots of fun. I did try putting a heavier 4S 1800 battery in it once, but it wasn’t fun to fly - flew like a brick. Try looking at some of the lighter “3-D profile planes” at Hobbyking to help you choose a lighter combination. I bet those would work on this very light airframe. Hope this helps.
@@2fly4awifi87 helps a lot, thanks!
Help! I kept breaking the props even though I have zip ties act as wheel, what else can be done? It's frustrating! How does other flier not breaking props without even using the zip ties?
xiandan54 your zip ties need to be taller so your prop does not strike the ground.
2FLY4AWIFI I'm thinking instead of using 6x4 I'll try 5x5 prop, and also double zip tie the rear ones so when I have a harder than usual landing it doesn't bend as much
xiandan54 How many inches or centimeters does your prop extend down below the fuselage? How far do your zip ties extend down below the fuselage?
2FLY4AWIFI zip ties put aside, I have exact same setup you have, 2826 2200kv etc, only diff is I use 3s 2200 battery, problem I have is that at first it seems fly fine, but then just a bit of wind, I kinda loses control of it, at first I thought it was loose battery, later on I found it's actually the wind, problem is, I'm flying in 7mph wind with not much of gust, how are yours handling the wind?
xiandan54 Your zip ties are too short. I’ve flown mine in 15 mph winds, and it flies really well. Yours sounds too heavy and under-powered. I’ve tried mine with a 3S 2200 - not enough power and too heavy. Try a 4S 1000. Feels like twice the power and half the weight.
Apologies, I see that further along you clearly state 6x4! Thanks, once again!
No worries. Yes, use a 6” diameter with a 4” pitch. You’re welcome!
@@2fly4awifi87 Just FYI, I've seen a HK vid, using all three G 'n G aircraft with a (near!) vertical takeoff, but I'll stick with the conventional, as I suspect they may have different power trains! Should be ready by Monday. Den.
@@denismoran670 I believe this power setup on these GnG aircraft could achieve vertical takeoff. It has a greater than 1:1 power to weight ratio with a 4S 1000 battery. Might need some launch rails (straws on the wings and rods mounted in a wood launchpad) for initial takeoff to keep it pointing upward. Try it! :)
@@2fly4awifi87 Not sure I've got the bottle for that! I'll fly it and get used to it first - will keep you informed, da boch, (goodbye/Welsh!), Den
In spite of hree months of gales and storms, I managed to fly this great aircraft! It's a real delight, and thanks for your help - also flying the J20, but finding it a handful! Diolch eto, Den.
sir which kind of esc are used for 2450kv and 6060E propller
Waqas Honey you’d probably have to go with a 40 amp ESC (which is much heavier than a 30 amp) with a 2450kv motor and a 6x6 prop using a 4S battery. If you’re using a 2450kv motor, I’d recommend a 30 amp ESC with a 6x4 prop on 4S. Lighter setup and more torque for vertical launch.
Wow, great :)
sir what is the size of propellors
6 x 4 prop, see this and more details in the description
