Gatehunter SLS 5 - Sub 200g 5" Racer

Finally got all the parts to assemble the first prototype of my ultralight 5" Frame!
I really love the Xnova 2204 motors. They have a super nice finish and feel incredibly smooth.
Unfortunately the HGLRC ESC was dead on allrival and I will have to postpone the maiden flight...

I'm quite happy to how the weight and looks turned out:

  • 200g w/o battery
  • 350g with a 1300mAh 4S
  • 45g dry Frame weight including steel hardware and canopy

Some details on the frame & what I plan to do next:

  • I designed the frame for a 20x20 stack, TBS Nano VTX and micro cam. This allows to have a super low aerodynamic footprint and frameweight.
  • The canopy has a little slit to clamp a linear anteanna but I am thinking about adding a mount like on my 6" for the new Micro Axii. The current prototype is a simple PLA print that I will repace by Laser Synthered Nylon.
  • The arms are 4mm carbon and the bottom plate 3mm. After playing around a little more with stress simulations I decided to upgrade to a 4mm bottom plate that should arrive soon.
  • Next step: alminum hardware! That should should shave off a little extra weight.

those props are killer on a light build too, I flew them today on a 680 +/- gram build with Hero 7 onboard and I kinda liked them. durability will be just about nathan tho. but very light spool up super fast. this is on a 2208 1800KV 6S 1250mAh helio/Strix F10 build on flosstyle 6" frame. I usually fly 6" but have been liking 5' lately and going to start building a few dedicated 5" builds. will try the hyperlite Astro Glide frame. still might get the 6" because I like my props spread out as farther. would love to fly this build you have. it looks pretty amazing. stretched X always flys better IMO

I love those props too. Not the fastest but they feel super precise and and reactive.
Actually I got quite a lot of requests to buy the frame so I ordered a bunch my 6" strech X racing frame and a 5" version of it (The one from my older post). I will give them away at production cost. Let me know in case you are interested.
But I'm not planning to dothis with the ultralight version from this post tho since I could't test it properly yet with the defective ESC.

I'll take one please, thanks for offering I'd really love it. thank you so much. I'll take a 6" version if you can do that? roughtly what would you be charging? very nice of you to do it at cost
thanks for your time, really appreciate it

How wide are the arms? 4x6 mm? I tried 4x8mm on my own frame and they broke on every crash. This entire build looks SO fragile! Maybe you can leave the bottomplate 3mm thick and make it a bit wider? I am very certain that the arms will snap first and that you wont need to make any improbvements on the 3mm bottomplate ;)
Can you upload a foto of the bottom of your drone? I can't see the motor mounts; 3 motor screws are enough and 2 will also work. I think that you can save some more weight if you redesign your "motorguard" to only one or two stings instead of the triangle;)

Yeah that 6 inch 6s remindet me. I remember when you pulled that beast out after the 1. NordmĂĽnchnerquadwettfliegerei :)

@UnicornMoe ... where along the arm did your prototpe break?

UnicornMoe   22 days ago 

Right where the arm connects to the main plate

She's a stunner! I really like the contours on the pod, and I bet she is amazing in the air. I would love to fly that rig. Nice work.

The iFlight XL5 V3 is a fantastic freestyle frame for the price. It features chamfered edges on some very nice quality carbon fiber. My goal for this build was to use high quality components at a relatively low price. Not only that, but I managed to reduce the number of solder points to the bare minimum. I've never built such a plug-in-play quad! The flight controller has an integrated VTX and doesn't..

Update! Happymodel has released a new V2 Frame which uses a more durable plastic. The Happymodel Mobula7 is one of those rare treats to hit the micro scene. Countless models hit the market every month, but this one just happens to check all the boxes. It's a 2S brushless micro with a 75mm motor stance. It's slightly larger than the more traditional 65mm brushed micros, but it's still quite small...
