Status: offline 		Not according to this! They claim that the stall speed stays the same..

In summary for the CH701

Fast cruise @ 5200 rpm has gone from 79 kt to 85 kt. = + 6 kts
Top speed has gone from 94 kts to 103 kts! = + 9 kts.
Fuel burn @ 75 kts has gone from 17 L/hr to 13 L/hr. = 23.5% less!
Best climb rate @ 55 kts is 100 fpm higher.
Best glide @ 40-45 kts is 100 fpm better.

Stalls (idle power, no flap):
With slats – no real stall, just a stable high-descent mush @ less than 30 kts.
Without slats, no VGs* – a distinct stall and roll to the left @ 34 kts.
Without slats and with VGs – no stall, just a stable mush @ less than 30 kts.

No worries foz. I am guilty of that on a regular basis myself!

I can't help but wonder why Zenair doesen't offer the 701/801 series with or without the slats.
