FabFeb Lost and Found
Found in the south west practice area at Lost Hills a Walston Transmitter(?) Has the following on the encapsulated label "MODA-2312, 217.011" and a date. No batteries were installed. Contact Jim Parker <This email address is being protected from spambots. You need JavaScript enabled to view it.>

2012 NATS/USOC
A few brave souls have stepped up to help out at this years NATS and I am appreciative for their help.
I still need a number of volunteers willng to devote a full day or even a half day to help with things like processing, scorekeeping and running a few events.
The NATS is labor intensive but the oppourtunity to help is rewarding. Please email me at either This email address is being protected from spambots.

Thanks!

Restored FAI FF Results History
Hello, Roger.
Please, take a look at the latest post at F1U.org.
I just restored lost results from WC, WCh, ECh since 1951...
This is the Information prepared by Ian Kaynes that was "Lost" when the FAI web site had a server melt down a couple of years back and has not been accessible since

>Measuring F1Qs' wattage
Measuring wattage for F1Q models without energy limiter (EL) is a topic that most of the US fliers have as well as CDs in F1Q contests have to address this flying season. Measuring the static motor’s wattage has been a point of contention, as it required a single measurement to get the “average”. However, the FAI free flight technical committee has reworked the specific text, which is currently available on http://www.fai.org in the documentation sector.
The following paragraph in the 2012 sporting code addresses the issue:
3.Q.2 paragraph b
For models without energy limiters the motor’s energy in war-sec over the motor run is calculated as the measured wattage multiplied by the motor run. A freshly charged battery (4.15 to 4.2 volts per Li cell, 1.2 volts per NiCad or NMH cells) should be used. When the motor has reached full power, wattage is measure using a commercial wattmeter via 3.5 mm male and female bullet connectors furnished by the contestant.
Comments:
1. Note that the wattage is measured "when the motor has reached (its) full power". The wattage is not measured at the instance the motor has started (which could be very high) but when its RPM has peaked, within about one second from the instance the motor was powered up. (Correspond to reaching maximum RMP.) So wattage measurement delay has a small element of judgment. This single measurement might is about 4-7% lower that the true average static wattage (by taking mutiple measurements).
2. 3.5 mm bullet connectors are only required for measuring static wattage (paragraph 3.Q.2.b). There are no connector requirements for models with ELs (paragraph 3.Q.2.a)
