this list is for those who have difficulty finding unique designs and are discouraged by the fact that there is more than one of a certain aircraft on simple planes. for you i have found these unique and semi-obscure aircraft.
i highly recommend you bookmark and share this page if you are a active player

Hughes x11
this plane is highly recommended for someone who is familiar with the p38 and counterrotating propellors. it seems like a easy plane to design and seems to be very flexible with levels of effort and skill


Arado ar196
this german seaplane is a somewhat challenging plane (due to the unique engine) but appears to be a plane that would yield wonderful results if done correctly.
highly recommended for people familiar with seaplanes and stylizing engines
(personal note: it would be very easy to build a biplane version)


BV138
german seaplanes in general are a unvisited subject that would yield original and unique results in simple planes but this seaplane is somewhat more uniquely designed than most.
This plane could prove challenging for those who dont have the basics of adjusting wingspan/fuselage length down. highly recommended for those familiar with seaplanes and the p38s twin boom design. this seaplane will need details and a little more dedication (not for bronze or below)


Leduc 0.10
This wonderful gem was rene Leduc's remarkable pioneering work into ramjets. looking truly out of this world this would be a very unique and popular aircraft on the simpleplanes community but you'll have to use modded probably. it does not seem difficult to make. recommended for those familiar with early cold war mig designs


Convair b58 Hustler
this supersonic nuclear bomber had arrived and disappeared due to the rapid developments in SAMs at the time
This sleek beauty will be a very challenging bomber to build due to its delta wing design and nice cockpit. it is a design that will demand attention towards its engine and cockpit thus those familiar with both would be recommended to build this design i have no doubt though that if done properly it will be in the first page of highest rated if done correctly


PE8
a massive Russian bomber during ww2 this aircraft will be extremely demanding to make and will take large amounts of finesse and detail. it would require a skilled player to pull this off


Miles m39b libellula
This was a model of a never achieved bomber project so it will require some imagination to build. this bomber (or fighter if you wish) will require basic familiarity with wing fine-tuning but will be a unique design. it does not appear challenging if you use a large modded ww2 cockpit and the modern engines already in simple-planes


Golem
this is a aircraft from gta5 that appears to be a modified twin beech i would recommend it for those familiar with turret mechanics. it seems like a very fun aircraft to fly


btw THANKS FOR GOLD EVERYONE!!! i know im not that active anymore but i decided to give y'all some help
