RE: Brio with a DEPS
I installed the DEPS in my Brio and did not move the hard points on the elevator.
The exit holes came out slightly further forward than I would have liked, but it works just fine. Just for peace of mind I added a 1/8" CF rod over top of the .007 rod between the exit hole and the elevator horn since it was about 10 or so inches.
I'm very happy with he system and I think it provides excellent even control.
The primary reason I went with the DEPS was to move the CG forward because I built my Brio electric.
