Lucy Long Range LLR6 LLR7 - OpenHD, Vista, Analog iNAV
A larger 6" and 7" version of the #minilongrange from Dave_C_FPV. Original design can be found here: https://www.thingiverse.com/thing:4584851
The #minilongrange is a perfect frame, unless you are looking for something a little bigger. Enter the #LucyLongRange LLR6 and LLR7. The frame and TPU parts have all been designed in Fusion360, this is not a simply stretched or scaled up MLR5, each part was redesigned for this larger scale.
Similar remixes and designs exist, however were always missing something, FC mounting patterns, ARM sizes, motor hole spacing, stabilizer ARM brackets. I decided to take the time to use the original LLR5 look and feel and create a new larger size frame incorporating the awesome chain ring bolt assembly process and adding all? the missing features from other designs.
v10.0
This is the initial frame release. Use the STL's and print this quickly in PLA to test all of your components before cutting CF.

If you notice any issue or need alternate mounting patterns, or feel something is off or missing leave a comment below.

Building Notes
Cut only 12mm or 16mm holes in arms for your motors. Cutting slots will create less strong arms. Same for support brackets.
Test fit a 3D printed frame first.
6in Version 4mm light ARMS, 5mm heavy duty
7in Version 5mm light ARMS, 6mm heavy duty
Purchase chain ring bolts with shoulder height that equals (0.5mm less) than the upper deck, lower deck, and chosen arm thickness.
Arm supports size from 2.5mm to 3mm seems good
UNI Parts are for all builds, DJI, Analog. OHD Parts are for OpenHD/RPI-Zero Builds
