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.
Take off & Landing weights - info updates ?
Re: Take off & Landing weights - info updates ?
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. The example weight and c.g. data is provided by Sling SA. Very impressed with different load configurations after plotting info on Foreflight App... excited to see how realistic these numbers are.
Numbers below are for Sling HW & HWTD (According to Sling Technical, weight limits are identical).
Max Gross Weight: 1120kg (2469lbs)
Max Take Off Weight: 1120kg (2469lbs)
Max Landing Weight: 1120kg (2469lbs)

CG Range 1969mm (6.427ft) - 2170mm (7.087ft) 18% - 33% MAC
18% MAC 600kg (1302lbs) - 950kg (2102lbs)
21% MAC 600kg (1302lbs) - 1120kg (2469.17lbs)

Ext Baggage 4210mm (13.81ft) - 3kg (6.6lbs)
Fuel Tanks 1927mm (6.32ft) - 198L (52.3gal) total.
Ext Fuel Tanks 1949mm (6.39ft) - 50L(13.2gal) total.

Tail wheel weight: 65kg x Arm: 6485mm = Moment: 421525kgmm
Left main weight: 285kg x Arm: 1567mm = Moment: 446595kgmm
Right main weight: 285kg x Arm: 1567mm = Moment: 446595kgmm
Computed Empty weight: 635kg, Moment: 1314715kgmm
