The Teksumo is a fun combat wing made from almost unbreakble EPP foam that is easy and cheap to build and will provide hours of "fly it like you stole" it fun!
Wings of course have a huge flight envelope, it's one of the reasons they are so popular, you can trickle along at walking pace, fly aerobatic or just see exactly how low 'n' fast you can get away with! Get it wrong? No problem, 5 minutes with some cyano & kicker and you are back in the air with a silly grin on your face!
With the reccomended power train, your Teksumo will have plenty of performance and won't cost the earth. You and your flying buddies can have hours of fun ripping up the sky with some high adrenalin combat flying safe in the knowledge that when the inevitable happens, you can fix it in double quick time!
Just received the kit. The parts seem to be nicely manufactured, although I would have preferred a bit softer type of EPP.
I wonder what happened to the glass fiber tape mentioned in the description. In the kit I received that fiber tape has been replaced with standard 3M Scotch tape. Not exactly the best tape for reinforcing your flying wing, but hey, I can always use it for making X-mas cards *)
I'm pulling about 50 Amps full throttle. The thin I forgot to say is I bent the motor shaft like crazy. I can't seem to find a replacement. Could you recommend a lower kv motor maybe? Bigger prop would be better. Would still like it to kick along pretty zipily.
I have this motor PRODUCT ID: D2826-6 2200, on a falcon wing with a APC7x6 prop on it, it pulls about 34.5 amps and has unlimited vertical, my teksumo has this motor PRODUCT ID: L2210-1650, on it with a MA8x4 prop it's not as fast but still has unlimited vertical, have a look in the file area, (TAB just above this question) my teksumo is in there with a CG machine, and there's others to look at as well, hope that helps you,
* last i put mine together n flew it.. its an amazing plane.. i used the 2826-1400kv motor with a 7x5 prop..good power but i was expecting more.. anyway i will put the 2200kv one.. its great plane although if anyone have an advise of an easier way to center the servos with the control horns?
I bought a servo tester off E B A Y for $3 delivered, on the tester it has 3 positions of which one centres the servo, very handy once you've tested the servo you press the button and it centres the servo for you! then install it in your model already centred. hobby king sell a similar one, PRODUCT ID: HKSESC_TST, it calls the centre NEUTRAL, same thing for $4.16, it's a must have!
Thanks mate, glad you like the video, dog's not mine it was just chasing my wing! Current battery is a 4 cell 1800mah, but got some 2200 4 cell on the way along with a bigger 1800 kv motor. Will post more video if it's a decent setup, should scream round!
Hello, my CG with HK2818 and turnigy nanotech 1300 battery is 222mm. But when elevator is in neutral wing nose dives down. If i set CG is in 200-212 range (like recomended)nose will become more weighty, and i think in neutral position wing nose will dive more. I need add more weight to motor side, is my thoughts are correct?
Mine teksumo fly's perfect at 200mm, with teksumo you need to lift the the elevons about 3-4mm at rest and leave them there, I adjust mine like that at the servo, they are NOT meant to be level. All wings need them to be lifted slightly then just trim the plane with the TX. If you add weight to the rear you will make it tail heavy! Balance it at 200-212 and lift the elevons and you will be ok.
Hi guys. Teksumo or Bonsai. Apart from size, how do they differ. Is the Bonsai twitchy and harder to fly ??
Will the Tek fly slow enough to fly in a single football feild if I keep it light ? It wont be my 1st plane. A friend bought a Telink wing that is really nice, but the Tek is 1/2 the price & I'd like to add a wing to the fleet.
Steverb There's a third option, the skywalker falcon, it's a wing as well and in my opinion the best of the three and I have all three, it cost me I think $36 from international warehouse, it's also the biggest around 1400mm, I think the bigger they are the nicer they fly,
you could put a turnigy 2826 2200kv and a 7x6 prop and a 2200 3s 20c battery, that would give you unlimited vertical, and around 120kph, with this setup it draws 34.5amps at WOT, I have a mystery 30amp esc on this set up in my falcon wing,..
This motor PRODUCT ID: L2210-1650 should give you 150watts of power with the right prop and 7.4volts, It's 250watts with a 3s battery, I use it on my teksumo with 3s battery's. I suggest you cut the threaded part of the shaft off and fit a collet type adapter.
I've got an 8x4 on a 250watt motor and it screams! great vertical!, I think a 7x6 on the same motor would do well also. it depends on your motor, mines 1650kv, so those props work well. what sort of motor are you fitting? that will decide your prop size.
That depends on how fast you want to go? you could put a turnigy 2826 2200kv and a 7x6 prop and a 2200 3s 20c battery, that would give you unlimited vertical, and around 120kph, with this setup it draws 34.5amps at WOT, I have a mystery 30amp esc on this set up in my falcon wing,.... In my teksumo I have a Turnigy 1650kv 250watt motor spinning a 8x4 prop, I reckon it may be a bit slower than the 2200kv motor but still has great vertical....If you want to rip the wings off maybe look at a larger 3000kv motor, in the end it's up to you...speed = power - weight/drag
Hey, I just got my Tek Sumo and have discovered that the slots cut for the servos are too far apart to connect HXT900's to my receiver (i.e. my servo wires are too short).
If i move the servos towards the center 1cm or so will I still be able to control the plane?
Or should i bite the bullet and get 10cm extension leads?
Hi, Sherlock Holmes. How on earth could you know I was gonna copy build this? You didnt because you are wrong.
I wanted to know the measures because Im gonna buy some balsawood to replace and strengthen the ailerons since im gonna put my gopro on it.
If you dont want to measure this for me, why do you even bother to reply this?
If you have something else on your mind just email me at arnvik * live.no and stay out of this discussion since you dont any good here anyways.
Haha. Thanks, your the man!=)
I havent got the plane yet, im working overseas and dont have balsa at home, thats why I need to know now so I can buy the balsa here.
I think the wing will get even better with balsa ailerons, and im gonna use both a CCTV camera and a gopro so I guess mine will be very noose heavy..
I put one of the sticky mounts on top of the cg and then hot glued around it to secure it. My setup was a 3530 1400kv motor turning an 8x4 prop with a 20A ESC and a 2200mah up front. All this PLUS the GoPro is pretty heavy but it just shows what this wing is capable of!
The wing isn't that thick so it would be half out and then the battery would have to be quite small to compensate for the extra nose weight. See I put the GoPro on top of the cg so i can still use a big battery and not ahve to change anything.
I think your plane weighed about 1.2kg? if that's right, this wing weigh's about half that, I think your prop is around 9and1/2 inches, which will be too big, you probably will need to reduce prop size to fit it in the space, and then it should scream! don't forget to do the CoG!
These kits were really not intended to fly at ultra high speeds & then you wonder why there's wing flutter- lol...perfect outrunner for this platform is a 300 size outrunner at around 1300 kv with a gws 7035 & a rhino 600 3s ... No wing flutter, nice smooth top speeds, although its not completely vertical while full throttle it's a ton of fun & slows down plenty slow to catch it by hand.. I'd get 3 more if I had room for em
I certainly don't get wing flutter, I don't know of anyone with that problem with teksumo, maybe you mean the slope soarer it has that problem sometimes, my teksumo has a 250 watt motor,8x4 prop I have unlimited vertical and good speed but no flutter, I prefer this teksumo to the soarer, my soarer I think is best kept light, the wing flex's very easily and it seems fragile compared to teksumo.
I coulda swore the wing flutter complaint was coming from a gent on this discussion & now I can't find it.. Anyway- your right, it may have been the soarer... I just got my teksumo at a rc swap meet up here in Washington & I liked the looks of it so I asked how much, the man said- Oohhhh - 30$, & I agreed... When I got home & looked it up I was a little upset to find out I shoulda got it for more like 15$ or 20$.. O-well, that's the breaks but this thing is really really cool for a super lightweight delta
Upgrade to a Turnigy D2826 2200kv motor
You can use either a 6x4 prop
The motor on a 3s 2200mah makes over 300w and really gets this wing moving
The motor comes with the bullet connectors pre-soldered, collet adapter and mounting bracket with the screws
Screws straight onto the Tek Sumo motor mount
Flight time is awesome with this setup, its easy to launch and its not to heavy
Me, my dad and brother all have the Tek Sumo with the same setup!
Sometimes I run my one on a 4s 1800 pack with a 5x5 prop Really gets it screaming but get flutter at high speeds
2 thumbs up!
wow what a wing! very very easy plane to assemble. i used a the DAT750 motor with a 2200mah nano-tech lipo.. hehe what over-kill but damm, so much performance. unlimited vertical, spinning a 10x7 prop only draws 16amps and flight time is easily 25min. very stable hand-launch and catch landings. can fly at walking pace or very fast. the combined epp construction and flying stability means its perfect as a trainer and also great to wow the crowds.. i love it! only thing that could possibly be seen as a negative is it doesnt like the stronger winds and turbulence (15kts>). overall 5 stars as u could not buy something that performs like this for so cheap anywhere else! great job hk!

I found the recommended motor 2818 was very underpowered for this wing. with the recommended 3S 1000mah still had to cut the battery bay a bit bigger and it did come out tail heavy.
This wing doesn't like slow speeds and bounces quite a bit with light wind.
I haven't done any modifications to it yet, will updated later.

I have one of these, and with a motor from the Angel EPP, 3s/2200mah/25c LiPo and a 8x3.8SF i got it up to 273kp/h (170mph).
And in addition, it is almost unbreakable

I didn't even think of putting a motor on it, it makes a gr8 slopie. Even with out a motor i needed to use the 1000 3s (witch is a perfect fit in the pre-cut spot) to get the c/g rite. Top little wing, gr8 for combat, hours of fun, cheep & fast to build, HXT900 are perfect servo's. If you haven't tried slope soaring grab a few mates & a few of these, guaranteed you will have a ball.
I am very impressed with this wing. Build was very easy and took around 2 hours total. Everything fit together with no modification and all parts mated perfectly. Note that when you install the servo's, you will need to place them with the arms forward and pointing to the outside of the wing, otherwise your going to be reversed in your movement. It is severly tail heavy, but a larger battery will fix that. I used the Turnigy L2205-1300 motor, a Plush 30amp ESC, and Hextronix HXT900 servos with a OrangeRC reciever and Nanotech 1000MA 3s 25c battery and have plenty of power for flying around, although it will not go vertical. Note the 2205 has a very small shaft and a prop saver is a must, so have a 2mm one to drill out or find a 2.3mm prop saver. The only down side is it has a huge fish on it...although it does look better than the 'standard' finish TechOne has on them. Make sure you put lots of up in when you build it, I assembled mine where you could just start to see the finish on top 'wrinkle' at the alerion and it flew great there without trim.
