How To Make A Long Range Small Techsumo/PopWing

by dentdynamics | November 3, 2013 | (13) Posted in Projects

I wanted to get into flying wings and after spending some time flying one on my flight simulator I figured I'd start out with something cheap. I opted for a Turnigy Tek Sumo from Hobby King. This little plane was super easy fly and had some great flying characteristics. It has the ability to do some crazy slow flight and has a really good power-off glide ratio. I flew the heck out of this little plane and eventually put a basic 5.8 fpv setup on it. I was getting some seriously fun flights out of this thing with flight times around 25-30 minutes on a 1300mah 3S battery.

Eventually, I crashed it just one to many times and decided to order another one. I really wanted to make a longer range version this time. This plane is marketed as a Tek Sumo by HobbyKing as well as a PoP Wing by some other retailer such as NitroPlanes.com. They are only around $35.00 and don't seem to stay in stock too long.

My minimum requirements were the following:

  • Longer range than what 2.4 control offered.
  • Some way to record HD footage.
  • RSSI so I know the health of the control link
  • Some way to know how much power I had used and how much remained

Based on these requirements I decided on the following:

  • EzUHF for the control link - I used the 4 Channel Lite receiver
  • Mobius camera for the HD footage which slides into a small bracket I made from balsa and light plywood
  • TBS Core OSD for the RSSI and power consumption/power remaining/time (There is a new plug and play version of the Core that does not require soldering.  Soldering this thing is a pain.  Tiny soldering. It is worth the extra $20 to get the plug and play version!)
  • ImmersionRC 600mW 5.8 video tx
  • Circular Wireless Skew Planar Wheel
  • Motor: Turnigy 2822/14 1450Kv
  • Servos: 2 Corona 9g
  • Turnigy NanoTec 3S 1300mah battery
  • Lumenier CS-600 Super - 600TVL D-WDR for flight camera
  • Prop: 7x5
  • ESC: Turnigy Plush 18A

This video is from the maiden of this plane. 

Here's a picture comparing the size of the Teksumo/Popwing with my TBS Capirinha. The wing chord on the Teksumo/Popwing is much longer than the Capirinha's which making it a bit more stable and forgiving.

The Turnigy Aerodrive D2822/15 1450KV motor with a 7x5 prop provides plenty of power.  Will do straight vertical as long as you can hold it there.

25-30 mins on a 1.3 Ah battery? Wow!

I nurse it along. Plane will cruise around at a quarter throttle.

It's not a copy of the TBS wing, the teksumo/popwing has been around longer than the Capirinha. People have been using it for FPV before it as well.

Yes. I know. But this wing is much cheaper. isnt it? ;)

So.. Cheaper means it's a copy?

No. Sorry, do not swear. :) I'm just a poor joke, I guess. : (But still your wing is good :)
I know where to buy it and so on ... Well, we are a little misunderstood each other. :)

I don't mean to sound rude, though I often do unintentionally. :) I just didn't want someone to be reading the comments and think that the TekSumo Is a rip-off of the Capirinha. I don't own either of the wings, so I'm not trying to defend either. :) I'm not sure where you are from, so maybe there was something lost in the language, now if you mean it is an alternative to the TBS wing, then we are in agreement fully! :) It is a great option when the Capirinha is out of your price range, like it would be for mine.

They are both good wings. I own them both. Each flies totally different. The Capirinha just sinks MUCH faster when you let off the throttle whereas the TekSumo has a better glide ratio.

Yes. I really mean that this is a good alternative to TBS wing. :) Sorry for my bad English. I understand spoken English, read by English great, but unfortunately I write or speak English is not very good. I am from Russia. :)

The popwing is a great FPV/training wing! I had one and broke the nose off of it 2 times and then I called it quits with it but I realized it flew so badly because the CG was not right.

Very cool aerial footage considering it was from a techone popwing! On our youtube channel we have some great HD popwing chase footage of another popwing as well as some interesting HD aerial footage from our HK EPP FPV. Check out our channel at https://www.youtube.com/user/HillcrestRCFlyers

your video immediately caught my eye. I am just getting back in to flying and i live in goose Creek. wondering if you care to share any local knowledge. Im up in WA state for the week but will be back soon. im very interested in FPV i haven't had anything in the air in 7 or 8 years, but am currently turning out some wings on my CNC foam cutter. send me an email xochal78@gmail.com
8 years ago i was a developing novice i had out grown my trainer and was flying a 4 star forty. but nothing crazy. I would like to find some locals in Charleston interested in collaborative foam design build. as i said i have a small 4 axis hot wire cutter.

You are in the same boat I was. I flew pretty hard back in the 90's then quit. Gas stuff. Then got into it again about a year ago and have gone nuts. The electric stuff has just come so far. I'll shoot u an email.

Nice job! Thank you for sharing your build as I am looking into the TekSumo for a long range FPV platform. What range are you getting with the 5.8 video system? Are you using a ground station? Would you consider 2.4 GHz for longer video range? Thanks!

Finaly got around to build my copy of your design :) I use a 5.8 GHz fatshark 250mW transmitter, 600TVL FPV camera and attached a mobius to it by hotgluing it a piece of foam. I also mounted the battery in the battery bay but i modified the bay so it is mounted on top of the airframe. I just love it now that the CG is finaly right. Took all the FPV gear, the mobius and some extra metal in the nose to get it right :D.

Thank you for the inspiration :)
