The Mr Steele ApexLR 7″ frame for longer-range exploration and videography.

Tension Braces

As prop size increases, the longer arms required causevibrationissues which negatively impact flight performanceand video stability. The Apex LR uses a unique tension brace design between the arms to increase stiffness and shift the resonant frequency of the assembly.
Pre-loading the armsin this way allows us to keep vibration to a manageable level while still using 5.5mm thick arms for a 7″ prop. Our approach saves 20g in carbon weight alone compared to equivalent 8mm thick arms.
The Apex LR is a variation on the typical ‘dead cat’ frame which we have modified to keep the front and rear motors aligned, allowing usto maintainthe much loved compressed-x geometry in the motor layout.
This ensures the frame remains balanced and flight characteristics are not compromised,unlike theclassic ‘dead cat’ design which moves the rear motors closer to the body and severely impacts handling.

Custom GoPro Mounting

For quick angle changes while filming, not many mounts can beat the standard GoPro tab and slot design. However the stock GoPro bolt leaves a lot to be desired for FPV use.

Included with the Mr Steele version of the ApexDC is not only a 3D printed mount, but also a new custom designed bolt, specifically for FPV use.
Our new bolt is machined from aluminium for substantial weight savings and has an 8mm hex on the outside, along with an internal 2.5mm hex broach.
Make quick changes to your GoPro angle using either the standard hex driver for M3 bolts, or the prop tool for M5 nuts, which you already have with you in your flight bag.

Caddx Vista Isolation

A major drawback of the Caddx Vista system is that the body of the unit is grounded, this can cause the conductive carbon fiber plates and frame hardware to be grounded too. In an ideal world this is not necessarily a problem, however in the real world it’s an accident waiting to happen.

Alongside the required M2 mounting hardware for the Vista, we also include a die-cut mylar insulator and custom machined ‘cone rivets’ from non-conductive POM.
When installed the Caddx Vista and also the M2 hardware is electrically isolated from the frame. This solution adds only 0.5g of extra weight compared to other designs using bulky and heavy 3D prints.

DJI HD Camera Isolation

Like the Caddx Vista itself, certain DJI HD cameras can also ground the frame, with similar unfortunate consequences.

Included with the ApexDC are newly redesigned HD camera plates and 3D printed insulation inserts. This keeps the camera firmly locked in place and reduces vibrations, whilst ensuring it is electrically isolated from the frame.

Antenna Mounting

Included in every kit is a 3D printed antenna mount for the Caddx Vista or other similar antennas.

In addition the Mr Steele version of the kit also includes a standoff mount for the Tracer Immortal-T antenna.
