Thats not a Piper or Cessna...allthough at first glance I thought it was L4 Grasshopper but it didn't look right !!!. Then the glimmer of recognition started to get brighter and I am now going to suggest thats its from a Maule M4. Very similar to the Cessna / Piper range but not quite the same...if you get my drift ?
Thank you Gary, and as for yours, first I have to figure out what I am seeing. Looks to be an exhaust port but not sure. Have to do a little searching but not sure where to start.
