They say the HSKRC Freestyle 250 is a clone of a more well known pilot designer frame. I really wouldn't know since I only own this one. The low-profile styling most likely was inspired (read copied) by the original, but the assembly and construction differs.
I made a few different design choices during the build:
-
ESC Placement - I routed the motor wires and ESC below the arm. It saves the ESC and wires from prop hits. I also wanted the ESC LEDs to be viewable from the underside i.e. when the quad is "going", instead of "coming".
- Lipo Orientation - The lipo battery strap slots were positioned across the body, so I went with it. I feel like it gives me slower, but more stable rolls.
I definitely recommend an AIO for this frame. A double board 30x30 stack is possible, but it would not leave room for much else. Even with the single FC layer, I had to position the VTX in the tail section. The receiver and and 12V regulator are a snug fit under the inverted FC. For SmartPort telemetry, the Flip32 requires a BAT54 Schottky diode across the one of the inverted UARTs. Fortunately, these diodes are cheap and readily available on eBay. ReadytoFlyQuads.com provides a diagram on where to install the diode.
The XSR-M antenna placement was inspired by Whiffles, of course.
I'm still in search of a 3D printing service with teal TPU, for matching, of course!

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..

I love that you got the LED's on your ESC's to point down, that looks aweseome in flight. I know ppl talk a lot about frame cloning, but it's not worth an extra $70-80 for the same frame. If the designers didn't try to gouge us on the prices, there wouldn't be a clone of every frame.... So that's on them. I dig that you went for the toilet tank battery orientation, how is that working out? Also: with your motor wires run through the crash absorbent structure added to the end of the arms, have you lost any motors/ESC's in crashes?
Thanks for the feedback!
Toilet tank battery orientation....haven't heard that one, but I like it! So far, I haven't seen the need to change it, so I guess it's working out. No major crashes or repairs yet. The motor wires definitely look like they're hanging out there, all exposed. I probably could have cleaned that up with shrink wrap to bundle them together.
