180 feet at peak height. It takes tremendous effort to get to the ceiling.Chuck,
Congrats to you team for super results. Your students will represent the US well at the Worlds. The salt mine flying should be another special experience.
A tremendous effort to build, test and compete the F1D’s!
Remind the forum (and me) the ceiling height at the team selection site (Lakehurst, NJ; hangar for the Hindenburg, I believe).
My problem was that I wasn't acclimated to the temperature this weekend. I had the privilege of flying at Lakehurst a couple times before the tryouts, but they were in much warmer conditions (low 80s). I was able to get a 21:30 on Labor Day, but when Tryouts came around, I needed a thicker cross-section motor to accommodate for the decrease in temperature. I didn't truly realize this til around Round 6. That's when I started amping up the cross sections and getting higher times. The trim on the last flight wasn't as good as I wanted it to be; I hadn't done a test flight between Round 8 and Round 9, but I think the rubber snap had jacked up something, I'm not sure what, but it slightly nosed down instead of up; probably something with decelage. Getting the climb to not be flat was probably the greatest challenge. The most I was able to climb to was around 110 feet over the weekend, and I got a 19 minute flight. I'm thinking if I'm able to get to the ceiling, that 21+ is within reach again.Crayola,
Thanks much. Bye the way, great job to you too! Pretty exciting finish.
Do you have plans to find the additional 4 minutes per flight (or more) that it will likely take to win at the World Championships? Maybe you already have this much capability in the higher ceilings at the salt mine.
