Weight capacity: The Standard Helix can support payloads up to 16 lbs (7.3 kg). The Helix Jr. can support payloads of up to 10 lbs.
Experience has shown that the length of the load can also limit the payload capacity, so a more compact setup is more likely to hold the maximum capacity, whereas an unusually long camera setup may decrease the maximum payload somewhat. Unusually tall (e.g. Canon C300) or long (e.g. URSA Mini) payloads may not physically fit on the Jr.
If you want to use a camera package of over 16 lbs. and/or longer than 13″, please consider the Helix Pro. More information can be found here.
