Wright Stuff Senior Flyer not going up
Posted: March 19th, 2019, 3:29 pm
Hello Guys,
I built my senior flyer from Joshua Finn's kit a while ago. When my partner and I tested it, we found that the plane refused to go up. We tried adding back elevator from the stab, and the plane still doesn't want to go up. In order to get a decent time on the plane, we have to release the plane from 6-7 feet tall, so the plane can glide down slowly. Sometimes the plane would go up, but usually maximum of 2-3 feet above the initial launching point. The area we are testing the plane in has no air vents to disturb it so air vents aren't a problem.
With launching the plane from 6-7 feet from the ground, we were able to get a record time of 1:46. I did forget to add my clay to my 5.5 gram plane for that test so I'm not sure how big of a problem the added clay will cause? We are using a 15 in rubber motor (1/8 in) and are using lubricant (Armor all) We stretched the rubber 3-4 times the original length, then winded 1000 times.
Another problem is the stabilizer keeps shaking back and forth very rapidly so we're bit getting the most efficient use of energy possible.
I have attached a link to a whole bunch of videos of us testing it for reference.
The stabilizer doesn't seem to show up as shaking in the video but is pretty obvious in real life. Also the plane appears to be near the celing in the video but in reality is about 7-8 feet from it.

Hope someone can help,
