rsync -append "chunk" size

I'm transferring 1.1 Mb files over very poor GSM EDGE connection. My 
rsync command is:

rsync --partial --remove-source-files --timeout=120 --append --progress 
--rsh=ssh -z LOCAL_FILE root at SERVER:REMOTE_PATH

File on remote server "grows" in size in steps of 262144 bytes. That is 
a lot, because system needs to transfer at least 262144 (before 
compression) every time connection is established. When I use scp --C 
chunk size is about 32Kb. Is there a way to change chunk size for rsync? 
I use rsync 3.0.7.
