We have almost all the 1/4 Balsa USA Biplanes in our club..
I would say the Gentlest flying are the Pup,SE5a, and N28 .....
To me best flier and also biggest is the Fokker D7
The Dr1 has issues on the ground but flies well and VERY agile....
The N 11, and 17 fly well but just don't have that much wing compared to some of the others.. I have an N11 ( electric) and like it but I find it more challenging on the landings.
We have had a Camel at our field but it had a short life..and there is a Spad being built ...so I can't make any evaluations long term on either of those kits...
At my club if its WW1 it has two wings ! hahahhaha so I can't comment on the WW1 Parasol kits much.
Also while I LOVE Balsa USA kits, never be afraid to beef up something or ask questions . Its always better to have a tiny bit more weight than this....
If you buy a kit and have any questions don't be afraid to send a message or ask.. I love talking kit building
