EEDSL: get a B200 with Raisbeck Props, air intake, leading edges and aft body strakes fitted. Where do you wanna go from Spa with which load ?
JAROPS 1 800m no problem up to 2-4 pax (depending on A/C empty weight) in a Rasibecked B200.
If non-Jarops no problem whatsoever.
Knowledge from 4000hours B200 (Serial numbers mainly BB1202 and 1478, both are Raisbecked)
Go for 2 man crew if financially manageable. Done both SH and 2 Crew, 2 Crew is safer in my opinion.
