I'm in the 7th grade, & my partner Alyssa & I have been struggling for the past 6 weeks with homemade planes using Chuck Markos' plan at first and then building the Freedom flight kit. The first plane we built, flew the best & longest at 20 sec, but never circled or climbed. We messed with the wing incidence, warp in/warp out, etc. but too many crashes ended up breaking the leading edge wing post. Our next 3 planes with the same design never did any better than 32 seconds.
Now, we are trying very hard to get the kit plane from Freedom Flight to fly & followed the 30+ instructions. We've had a lot of breakage with the ribs attached to the carbon fiber & have had to glue them back together. The plane was stalling & not flying. We lowered the leading edge by 1mm & it now "flew" for 6 seconds while banking left. We had a lot of trouble with where to place the wings due to the CG being so far back.
Is there anyone willing to take a look at our measurements, weight, etc. & perhaps help guide us to get the plane to actually fly? We've put in a lot of time building 5 different planes, and none fly. No one at our school actually knows how to do it, and we have tried to follow instructions & guidance, but we are very frustrated. We have Regionals in less than 2 weeks, and right now, we have nothing working.
