Take off & Landing weights - info updates ?

[Luna 420]

Hi, Is there any update to this post?

We are still developing the take-off and landing performance tables for varying weights and altitudes, but we do have preference information at MAUW of 1,050kg. The tests were conducted at MSL on a smooth and level tar runway:
Takeoff:
Roll: 270m (shorter possible with STOL procedures, around 230m)
Distance at 50ft (15m): 600m
Landing:
Distance from stopping point at 50ft: 550m
Landing Roll: 180m

We will update this thread when we have performance data for lighter weights.

Anyone familiar with current numbers please chime in. Weight data is sourced from Sling HW document DC-POH-001-X-G-2.0 POH Revision 2.0 Date 2025/01/28. I do not have any examples of currently flying empty weight + CG data of a Sling HW or HWTD.

Numbers below are for Sling HW & HWTD (could not find differences between configurations).
Max Gross Weight: 1120kg (2469.17lbs)
Max Take Off Weight: 1120kg (2469.17lbs)
Max Landing Weight: 1120kg (2469.17lbs)
