When we installed a L2400 as a replacement for a L2000, it was a direct swap... just altering the length of the pitch change cable.
If you want to use a L2000 pitch change mechanism on a L2400.... They are just very slightly different and you may find that the prop doesn't feather completely and may windmill a little bit. regards Rob Rob Thompson 0429 493 828 (Please note that my new email address is [email protected]) On Tue, Mar 16, 2021 at 10:54 AM Michael Stockhill <[email protected]> wrote: > Thanks, Ian. > > M > > On Mon, Mar 15, 2021 at 4:43 PM Ian Mc Phee <[email protected]> wrote: > >> Michael >> >> Some years ago we fitted a Sauer S2500 to our dimona and were able to use >> the gear change metalwork.
