Mini Flame Wheel arm - reinforced and with integral landing gear.

thingiverse

This variant of the mini flamewheel arm boasts an impressive balance of stiffness and strength. Its integral landing gear stands at a robust 58mm tall, providing stability on rough terrain. The motor bolt pattern has been carefully designed to accommodate both 16mm and 19mm diameter mounts, offering flexibility in motor selection. To cater to various motor sizes, the center hole is slightly larger than standard, making it compatible with virtually any motor type. For secure mounting, the holes are optimally spaced for use with three M3 capscrews, but can also accept two M2 screws paired with washers for added reinforcement. The entire arm/leg assembly weighs in at a remarkably lightweight 18G.
