Hello all,

I am wondering if anyone has a score prediction for Michigan's state tournament coming up this Saturday. I've been consistantly hitting around 2:35-2:40 and I'm wondering if I should expect a medal or not. (top 8 medal)

Ceiling is about 24 ft

Depends on room width and air currents and other unknown variables, but that time has placed top 10 at other state competitions of similar height

Michigan flying events are always highly competitive. I don't know down to 8th place. It will be interesting to see how the competition goes this year. Good luck, and don't give up on improving! Competition leads to advances, not settling for 8th place!

Most importantly, be sure to study your log book to find the best competition setup. You may find some open-ended trends that point to better extrapolated performance.

Thanks!

A couple questions regarding the rules. It mentioned in the rules that you can get 5% of base score if you launch in the pre flight period. Does that only apply to the flight launched in that time or does it apply to all (the best) times achieved during the next 8 min flight period? What happens if I trim instead of official flight in the pre flight period?

Also, I'm assuming they don't pause the timer during flight? (Like if my plane fly for 2 min they don't pause the 8 min timer during flight?) Thus, if that is the case should I prepare multiple motors and wind up a second motor while plane is in the air?

EDIT: shoot I misclicked and posted it twice, how do I delete this one?

[coachchuckaahs]

The 8 minute timer starts at the launch of any flight, trim or official. The single bonus applies to all flights. So one clock to beat for the bonus. But, once you launch that first flight, you are in 8 minute window to launch both official flights. Miss the 3-minute window and you have no bonus for any flights.

The 8 minute window starts with first launch of any type, trim or official. It continues throughout the flight, So you have 8 minutes from your first launch until the second official flight must be launched. Any official flight launched within the 8 minute window will be allowed to continue to completion.

This is my interpretation, and consistent with prior years. As noted elsewhere, this is not an official interpretation of the rules.

They do not stop the watch. Bonus is applied to bet flight. I personally set up a motor while a plane is in the air, so I can spend more time maxing the motor out

So... I have a situation. Recently the motor I had been using to get my best times broke (probaly due to repeated usage) and that was the last bit in the same batch/bag. My coach ordered some new rubber from the same place (freedomflight) and they're the same size. When I created a new motor and wound it up a few times to get the stretching going I winded according to my best times. It turns out that even though this motor is the same width as the previous, it is much easier to get to the same torque compared to before (before I had to back wind 26 to get to 0.38 but now I only have to back wind around 15-18).

Is this a major concern? It is variations in rubber width? Our competition is this Saturday so I'm a bit worried right now about this new variation since I may not have time to test fly before competition.

[coachchuckaahs]

There are definitely variations batch to batch of the rubber. While ffm cuts the rubber to width, what is important is the Kinnear density, or grams per inch. Even if this is the same, the date code of the rubber can present differences, though the tam super sport rubber is more consistent than prior historical rubbers.

Weigh a few inches of the new rubber on a mg scale, and compare to the old.

Keep in mind that Dave delivers a lot of cut rubber, by width, and it is highly unlikely you will get some from the same batch (date code) as your prior order. This is simply life, not a q.c. Issue for Dave. We always measure of rubber in g/in, which accounts for the cross sectional area (not just width) as well as the density variations. This even varies considerably within a single box of rubber.

You could try a price from the opposite end as well.

Not much you can do now except adjust your prop to match the new rubber, through testing.

We usually get 5-10 flights out of a piece, someone less if winding hard. We go through about half a pound of rubber each year, more this year due to more variables to test.

Ok thanks. I will follow what you said tomorrow. Also I might be able to get in an hour of practice. Any starting pointers for me to save me some time? I've been using a non flare prop that is pitched to 40 degrees, after I fly regularly like before if it doesn't work as well as before should I increase (catch more air) or decrease pitch?

Thanks coach again for all of your help, we're a fairly new team and without you and all the other helpful people on the forum I definetly wouldn't be at this point of excellence and learned as much.
