Build Error - SlimRemix for N910C

Hi,
I'm trying to build SlimRemix for my device N910C. I am almost finish but got this error:

Code:

---

/home/agentdeep/android/slimremix/out/target/product/treltexx/recovery.img maxsize=8380416 blocksize=135168 total=11384832 reserve=270336
error: /home/agentdeep/android/slimremix/out/target/product/treltexx/recovery.img too large (11384832 > [8650752 - 270336])
make: *** [/home/agentdeep/android/slimremix/out/target/product/treltexx/recovery.img] Error 1
make: *** Deleting file `/home/agentdeep/android/slimremix/out/target/product/treltexx/recovery.img'

BTW, I did not get this error when I build CM12.1 and all is fine.
Thanks.
