Spits & Hurri's to 25,000 + feet in RL?

[SEE]

Spit 2a best Climb Rate was around 3000 ft per minute - to 10,000ft should be less than 4 minutes - have you timed it in game Catseye?

Spit1's was around 2500ft per minute (depending on prop fitted - csp a bit better).

Hurri had slower rate of climb but I don't know the exact figure.

I haven't timed them but I think it takes about 10 minutes to get to my preferred altitude and seemed right so never actually timed in game.

You don't see many Rotol Hurris on line any more thats for sure - mainly Spits but I still like the 1a.
