I am posting this to both groups.. rotary and Canard.. in hopes of getting some good ideas..

I will be mounting a Ivo Magnum on the back of a rotary powered velocity.. I've heard the horror stories with the horizontally opposed engines and IVO's but will give it a shot on a smoother running engine..  The inflight adjustable propellors have a reversible motor in the hub, and its power is provided to the prop by a graphite two conductor brush assembly in a plastic housing.

What I am having difficulty in doing is devising a sturdy enough brush mounting arrangement. 1st arrangement (meant for ground use ONLY consists of some home depot aluminum angle, threaded rod and a few nuts and locknuts.. I tried building a 2nd arrangement tonight out of 26 ga galvanized sheet steel with stiffeners built into two opposing layers (back to back). In the absense of workable feedback, 3rd arrangement will be out of 16 ga sheet steel.. to try and develop rigidity, and will have it form an L or J channel with a horseshoe cutout on the long side to straddle the propshaft and engage as many bolts on the PRSU bearing retainer hub as possible. Currently all my mounting schemes involve the bearing retainer ring mounting bolts on my redrive.

I have a RD-1B redrive from real world solutions as the most likely anchoring point.. just want to get ideas (and pictures) from those who have actually made this work.
