I second what Mark said.
Go for it!!.
I use one on my Pilot BeatOn 90. The plane was ARC, so I had much less trouble installing the support for the bellcrank.
Just be careful when making the holes for the mounting plates that comes with the bellcrank. They are thin ply and should be installed inside the fuse.

I also recommend ball bearing linkages on all the connections points to make the elevator most precise. I tried ball links on bellcrank output arms, but no good.
Use carbon fiber pushrod from servo to bellcrank, bellcrank to elevators.

Good luck.
