From what I have found there are no available Plans, Kits or Downloads for the GP-4, however with modern tech like 3d scanning iPhones, Powerful Cad Software and 3D printers it would not be too difficult to create a RC version of this impressive Aircraft.
When you see it in person its difficult to get the whole aircraft in one shot with out a wide angle lense
Much of the structure is actually laminated wood with grain direction for optimized strength and is a pre curser to modern composite aircraft structures. They have a few displays of some details of the construction methods along with a scale model of the aircraft under construction.

My personal thoughts on the aircraft with the context of seeing the 2004 movie the aviator and a few documentaries on Hughes is its a mix of a technology path finder paving the way to large aircraft structures and systems while being a tragedy for Hughes personal aviation career. He was never the same after this project.
Aircraft like his racer and XF-11 had fairly quick development times however the H4 flew 2 years after the end of the war it was supposed to support. Because the project was under a government contract with government funding it Aircraft like the Grumman albatross and Martin Mars Evolutionary and nature compared to the revolutionary H4. However this difference was not taken into account for the oversight, visibility and pressure.
This aircraft serves as a cautionary tale for any company or individual taking on a “huge leap task” with out proper technology development and stepping stones setup at the beginning. Crawl, walk, run marathon or sprint. This is hubris that has effected my self and have seen first hand at companies I’ve worked for.
The Aircam was developed in the mind 90’s by Phil Lockwood for the National Geographic Society for photography & research in the rain forest of the Congo
The twin engine’s mounted close together coupled with its slower flying speeds adds extra margin for getting into areas that may be considered too risky for more conventional manned photo aircraft. The view out the front is very UN-restricted and bubble canopies are available for flying in rain / snow.
And for a good aerial photography alternate to the GoPro that has served me well is the EK7000 by Akaso, It has a remote control wrist strap & blue tooth connectivity that helps with remote mounting on an aircraft (wing tip, tail, under the fuselage)

Cinema Drones like the Mavic Mini can provide excellent for independent film makers and you tubers, however locations that may look like a great place to get footage may be in controlled airspace or near an airport. Here are some resources for safe operation, keeping out of the news and staying in the good graces of the FAA
The moonbat is quite the interesting WW2 Prototype Aircraft from McDonnell, the only functional prototype was lost in a fire during testing in 1944 and the project was canceled later that year. The Aircraft was distinguished by its large blends from the wing to the Nacelles & Fuselage.
This aircraft was influential for my Sr Design project at ERAU that had a 2 seat general aviation aircraft with large fairing between the wing and fuselage.
Outerzone does have a 1/10 scale RC model for the scratch builders out there.
