I might be one of the rare European clients that got the privilege to get his hands on these beauties.
After almost two years since it first appeared on their channel, (yes 2 years!!), I finally received in November the (way too) long awaited K-Holes from a reseller of FÜ-RC products.
FÜ-RC is really not the most reliable company in terms of marketing and communication, but we have to admit that their products are just next level s***.

The Frame
I already have a Kore V2 and this thing is a beast, whether in handling, speed or durability, it cuts through the air in a very unique manner. As the K-Hole is a complete new design with interchangeable arms and is supposed to be lighter (...and of course it just looks too sexy) I got very excited about it. It also comes with aluminium parts, motor pads with one nut solution, a micro cam mount and a bottom plate that all lock together with the arms and the canopy to strengthen the frame even more. For the cost of some additional weight. Depending on what configuration you use, the frame weighs between, 68 gr. and 95 gr.
Overall, it is really an awesome design. So I bought two of them + some spares.

The Build
Unfortunately I encountered with the K-Hole some of the same challenges I had with the Kore. As I new I could get two of them, I also ordered a bunch of FCs, ESC, Cams, VTXs, antennas in order to start the build directly. For the K-Hole, FÜ-RC said they addressed the room issues people had to build the Kore. First bummer, my standard 4in1 ESC from Airbot couldn't fit on the main plate. So I had to buy newer 4in1 ESCs with a smaller footprint such as the DALRC Rocket and the Hobbywing V2. Both being BLHeli 32, not the best choice for me, as I run a Mac. So for motor directions, I had to test and swap wires.
Also, the aluminium cam mount is made only for micro cams, so I had to use the plastic one in one of the builds to fit a Foxeer Predator mini. The aluminium one nut motor pads are useless, as they don't align with the motor wires and the arm hole...
Furthermore, The frame comes without holes for the receiver Antennas and the VTX antenna. But that was a quick fix. Just had to make sure the to drill the antenna hole on the canopy at the right angle for the antenna to never come close to the props, whatever antenna I may use in the future.
Once eveything fitted, there's not much room, especially if you use a mini or full size cam, and a normal sized VTX.
It's not been an easy build but it was fun. Just chosse your components wisely.

The Flight
Apart from a simple hover flight, I still coundn't fly one of my new K-Holes, mostly due to the harsh Winter here in Europe. So I'll post an update as soon as I manage to get several packs in and abuse it as it should be.

A couple years ago I built the TransTEC Frog and since then I've been patiently waiting for another TransTEC frame to catch my eye. Fast forward to today and the TransTEC Laser S is that frame. It's a 82g racing frame that features 6mm arms, a TPU micro cam mount, 30.5mm and 20mm stack mounts and 3K carbon and 7075 hardware. My goal here was to build a high quality 6S racer at a reasonable price. I'd..

This is the 4th installment to my popular "Wizard Killer" series, and is based on the popular Wizard X220HV 6S. As usual, the goal was to build a substantially better quad, yet come in below the retail price of the BNF kit. Here are some of the improvements: Higher quality EMAX ECO 2306 1700kv motors Foxeer's top-of-the-line Falkor mini camera Eachine 25mw-1000mw Leaf VTX with microphone Tools This..
