- Then measure around the fullest part of your bust 2 , again keeping the tape horizontal.
- To determine the size of pants, measure the girth of the waist 3 and hips 4
- The following charts will help you match the designer’s size scheme for this product (indicated in the dropdown) to your usual size

The Scorpion HK-4020 & HKIII-4020 motors are built with 8mm hardened steel shafts that will last through countless hours of flying fun, but occasionally, on a "Less than Perfect" landing, you may bend or break one. For these occasions, we offer factory replacement shafts for all the HK-4020 & HKIII-4020 series Scorpion Helicopter Motors.
The shaft for the HK-4020 & HKIII-4020 series motors measures 8mm in diameter, and is 78.7mm in long. The Stock HK-4020 & HKIII-4020 motors have a 5mm output shaft end on them to allow the user to install 5mm pinion gears. The shaft kit will also fit other brushless motors that require an 8mm shaft of this length with a 5mm end. The shafts can be cut shorter with a Dremel tool and a cut-off wheel if necessary to fit other motors.
