Any recommendations for improving flight time based on this video? The effective ceiling height was 60 ft at the center, while going down to about 50 on the sides.

I just finished my state competition with approximately a 60 ft ceiling height. The facility was actually open the day before the actual competition for competitors to test fly, so I did many tests before hand. I did do partial motor tests prior in my high school gym, and scaled the motor when I got...

For Indiana state, first place was 3:33 in a field with an effective ceiling height of 60 feet.

So a question about test flying. Say I fly at noon, but want to get to the area some time before hand at around 10 to do some test flying. If my partner for that event is not available until 11:30, am I allowed to use one of my team's alternates to help me test fly up until 11:30, even though they a...

When constructing a 2/3 partial motor stick, I know it should have a weight equal to 2/3 of the weight of the rubber band. However, if I plan to test using many different weights of rubber, would I have to construct various partial motor sticks each with varying weight? Or could I add clay to reach ...

Calgoddard,

You've made it very clear. Thank you for your explanations.

That is an amazing flight! Because their plane deadsticked at the end, could they have increased their pitch slightly to decrease the rate of usage of the motor? How do you know whether to increase the pitch or increase the rubber length in that case?

I will try to do the 1/3 motor testing in my gym.

By massive open area, I mean an indoor football field. The roof meets up in a center line like a triangle. The center of the triangle probably has a max height of 90 feet unobstructed, while the edges have a height of maybe 50-60 feet. I will work on doing partial motor tests, but I am concerned tha...

Thank you calgoddard for the information. Though a question about calgoddard's post.. Because my state's wright stuff will be held in a massive open area, I'm testing various modifications on the FFkit to best fit the competition ground. With regards to extending the motor stick, how much benefit do...

Balsa, As far as I know, increasing pitch decreases the rpm because it faces more resistance (catches more air) when spinning. As a result, it will spin slower, causing less winds to be used up. It is recommended to increase the pitch if the airplane is running out of turns. Vice versa, as in your s...
