For state last year we had about a month and a half to fidget and fix out things.
My teammate spent that trying to get a good 2-minute flight out of his freedom flight kit.
I didn't have much interest in building a kit plane, so immediately took a look at my plane that i had built for the Invitational and Regional tourney, I noticed that the flex in my motor stick was decent variable in my flights.
I immediately went to work to try to reduce the flex.
Long story short I designed a new (But kinda heavy) motor stick with a sanded down 1/4 inch balsa stick, and I glued and wrapped a carbon fiber rod to it. (wear gloves and a respirator PLEASE when you sand that stuff, I made that mistake and it's not nice).
I modified a wing design that one of the coaches had made up, which was cool because it allowed for more surface area while staying under the 40cm (At the time) wingspan.
and just to look different I put the verticle stab on top like most big boy airplanes.
IN the end, we competed with that plane, and it landed in a basketball hoop at like a minute and 5 seconds, then it broke when my teammate was getting it down. so sadly we didn't place well, but the plane flew amazingly before it hit the ceiling, a basketball hoop and broke. My school has relatively short rooms to practice in and a good bit of ceiling clutter, but the longest I got it to fly was 1:59.9 seconds. (Keep your rubber bands tight, mine snapped forward when it was 3 feet off the ground and it nosedived)
Wow, that went longer than I needed it, eh.
How may I be of assistance (If still needed)?
