Upgrade arms for the Helix. Based on the Kraken 7 GT, these arms are compatible with Helix allowing you to upgrade your Helix to fly 7inch propellers. Featuring the same carbon fiber foam sandwich on as our V3 Worx arms, they provides greater tensile strength to weight ratio compared to solid CF arms. These 5mm arms are stronger yet lighter than equivalent 4mm thick arms.
The arms are fully compatible with your Helix 6 inch frame. As the arms are 5mm thick, longer motor mount and frame screws may be required when converting your existing frames. Due to the use of our WORX materials, your 7in Helix weight is only around 10 grams heavier than the 5in!
As the motor mount holes are 19x19, regular 220X size motors with 19x16mm mount pattern will only accept two screws.
For 7 inch props, we recommend a 2206-2207 size motor with 1400-1700kv. For example, the BOLT 2207 1660kv which was specially developed for 7in frames. We also recommend the BOLT-Less 20amp escs for these motors.
Contains one arm.
Note:
- Arms are typically 4.8mm thick
- Composite sandwich arms are subject to more damage than solid arms from an edge impact with solid objects including metal and concrete structures.
