I got a pair of these frames for dirt cheap and I was always a sucker for the Talon from Karearea. So I bought the parts I needed to build a nice racing machine. The weight including battery stap and props (excluding battery) is 342g.

Challenges I encountered during building:

• FrSky telemetry did not work out of the box using a FrSky R-XSR receiver. I had to use the (minuscule) uninverted SmartPort pad on the R-XSR but with this change everything worked like a charm. I flashed the receiver with the FPort firmware and didn't use SBUS at all.
• The LED strip from Matek refused to work with the 5.25V the Mamba FC provides on its 5V pads. After adding a diode to the 5V cable to the LED strip it worked as expected.
• The piezo buzzer on the Matek LED board is insanely loud. I had to gag it with some electric tape to not become deaf when testing on the bench.
• You will need a little longer battery straps compared to quads with just a bottom plate because the aluminum profiles at the bottom of the frame add to the length.
• If you do not provide some padding the battery will just sit on the front and bottom aluminum profile which will dent the battery on a hard crash. In put some adhesive silicone pads unter the bottom plate and over the profiles.
• If you don't like to use the provided antenna mounting hole in the top plate mounting can be tricky. However, the top plate is really thick (3mm) so I don't think this will be an issue. I will add a Foxeer Lollipop antenna later and use either a 3D printed antenna mount or zip ties to keep it up and out of the props.
