Hello, I am relatively new to this hobby. I am in the military and have been deployed on and off since 2002. While I was deployed in 2004, my neighbor set me up with my fiorst RC trainer. It is a 40 size Chinese made ARF trainer and is still serving me well today. A few years ago, I bought two planes from another different neighbor. One of them is a WWI type, with a inverted gull-wing. It is looks alot like a Polish PZL-7. But I do not know what kind of plane it is. It has never been flown, looks like a 40 size would work well and has a wing span of roughly 55". I am attaching a pic of it here. If anyone knows what kind of plane it is, I appreciate some info on it. I am debating selling it, but until I know what it is, i doubt I can!
Thank You,
Ubbo

Looks like a Nieuport, just after WWI.
No idea on the type though.

weren't nieuports all bipes?

Could just be a bash of some high wing trainer with parts from here and parts from there. Basics are there so it does fly.
