Upgrade the already great looks and performance of your Hobbyking™ Thorax Mini FPV Hexcopter with these super tough, professional looking after-market aluminum alloy arms.
As a direct, purpose designed replacement for the stock arms these fit the Thorax frame without any modifications and have been optimised for a more rigid frame with all of the associated benefits such as faster response and greater handling precision.
These alloy arms also act as a heat sink for your motors, dissipating heat from the motor and transferring it along the arm; helping your motors to run cooler.
• Stronger and stiffer than the stock plastic arms.
• Works as a heat sink, dissipating heat from the motor.
• CNC machined to give a nice surface finish and look that no other multirotor will have.
• Universal motor mounting
• Stylish CNC bevelled finish
Material: Aluminum alloy
Motor mounting holes: 12, 14 & 16mm
Weight: 15.8g each
I ordered 3 pairs of these as soon as they came out, and I received them today. Overall, they look very nice. They are black anodized with bare metal edges inside and out. Overall the dimensions match the original G10 arms, and they are noticeably more rigid.
They weigh just over the listed 15.8 grams (I got 15.82), so a full set of 6 will add 21.6 grams to your build.
The one problem is that the mounting holes for attaching the arms to the frame do not line up properly with the those in the original arms or with those in the frame. The outboard hole is a millimeter or two too close to the inboard hole, so that it doesn't line up with the holes in the frame. You could drill out the frame or the arm to fix it, but this would weaken the attachment point for the arm. If you're buying these to have a stronger arm, this is exactly what you don't want to have to do.
