Need help locating information and details for the HP-5. I've been drooling over old photos that I've garnished from the internet. It is so intriguing! But I'm lacking a lot of the details: critical to building a replica would be the airfoil, spars, instrument panel, controls...

Any suggestions or clues would be greatly appreciated.
Would records of pioneer or pre-war AC be available at the Imperial War Museum in London or at the PRO library there?
A remarkable 1:72 scale model was made by Karen Rychlewski.
HP-5 model
Klaus in Bavaria has built an excellent, large 1:3 scale RC.
Klaus' RC
I've learned that RC plans are available in a Nov 1994 Aeromodeler mag. I believe that Klaus built his from those plans, but no clue how authentic they are compared to the origional AC. My next step is to order the plans.
The AC was considered underpowered through its developmental stages (50 hp Gnome 7-cy.) Would it be concievable (or overkill) to put in a 100-110 hp radial given the amount of air resistant cables are whistling through the air?
There doesn't seem to be many 7-cyl radials available... Rotec and ??
Chech's are manufacturing 3 and 5-cyl radials but Pavel (Vancouver, BC) suggests that they are still in development stages and need to prove themselves first. See descriptions on Pavel Novak's web site at
