Seems like I am following Sparky's foot steps growing out of the airplanes into race cars = at our house now it's: Honey, I got rid of them fly toys now I need to get me one of them salt speed racers

From my experience - Flaps on the 140 and 170 were a "nice accessory" and most often useless, unless you wanted to take off on a snow covered runway, accelerating to speed , then use the manual lever to set flaps and "pop" it out of the snow.
Looking forward to a lot more historic photos
