Hi all,

I recently bought an ASH25M, which still got the Technoflug prop. Now many PPL advice to go for the AS prop. I asked Schleicher and Rolf went like: "At least we can repair it, if it has a crack or so." - But I could not manage to get information about performance.

Anyone switched to the AS prop? Is there some worth mentioning difference in performance? Like aceelartion or climb rate? What about weight difference?

Thanks in advance for any hint, Nik

p.s.: If anyone is looking for an ASW27, I just got one too much

I seem to remember from the ASH 26E documentation that the ground roll reduced approximately from 300m to 200m. Engine RPM at wide open throttle is signicantly higher with the AS prop, to the extent that you have to throttle back very early after coming off the ground (RPM over 7,500 was allowed IIRC for only 20 secs, though I used to leave the throttle wide open for a bit longer). Quoted climb rates and cruise speeds did not change.
