Where were you able to get the plans for the P-40? I hunted and was never able to find a source that would respond to contact. I did end up with a set of 3/4 scale Jurca plans for the P-40.There are two War FW190's that fly in the US. Both are overweight, a little. Both fly well and stall around 60-65mph. The scale is actually 60%. I would love to redesign these to meet their design EOW of 620#. I am friends with a composites engineer and we believe we could build a flying WAR with an EOW of 550#. We have a set of plans for a WAR P40 that may be our first build.
