The Quicker was a popular design in the late 50's in my area. The top setup was a Johnson Combat Special and a pen bladder in plastic can behind the engine. The only major downside was breakage of the engine mounts in every inverted crash and some inverted landings.
The VooDoo used essentially the same wing with a side mounted engine and much-simpler stabililator. In the Detroit area, where combat was huge, the Quicker was instantly replaced by the VooDoo, including, I believe, some damaged Quickers converted to VooDoos.
All the old uprights on the late 50's, T-Square, Renegade, Hornet, and Quicker went the way of progress when we saw the light of the sidewinder engine mount.
