RDT changes

F1A models may use radio control only for irreversible actions to

control dethermalisation of the model. Any malfunction or unintended

operation of these functions is entirely at

the risk of the competitor.

This change was made to permit RDT to extend the DT time as well as D/T the model.

Also RDT was extended to the provisional classes such as F1H, G, J,..

A further change, not specifically involving RDT but historically associated with it, was the proposal from the FFSC to remove the rule which does not give the 20 second attempt to F1A models which dethermalse – bringing F1A into line with the other classes.

F1Q EL changes

a) For models with energy limiters. The allowed energy amount starts

to be calculated with the launch of the model

and finishes when the ESC has stopped supplying energy to the motor.

If the energy limiter does not have the capability of detecting the

launching moment it may start its calculation from the beginning of the motor run. The

measuring device (EL) has to calculate the energy consumed in real

time. After coming to the end of the limited energy supply, the motor(s)

must stop irreversibly.The energy limiter must interrupt the impulse

signal from the timer to the ESC and cuts off the motor(s) in the

moment the given energy limit is reached, without need of interaction

of other devices. The ESC must always operate via its series

connection to the energy limiter and not with direct connection to the

timer. The timer stays independent, but the energy limiter may inform

the timer about the end of the energy supply.

For energy limit verification a measurement device is to be used with

the capabilityto start the measurement separately when the start

button of the model is released. This device is to be connected between

the battery and the model’s connectors via 3.5 mm male and female

bullet connectors. The measurement device must store the data of time,

current and voltage (or wattage). The sampling rate must be 5

samplings per second or better. The energy amount starts to be

calculated with releasing the start button of the model and finishes

when the ESC has stopped supplying energy to the motor

For models without energy limiters the motor’s energy in watt-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. After the motor has

reached full power, the power is measured at a time equal to the

nearest whole second below half the planned motor run. The power is

measured using a commercial wattmeter via 3.5 mm male and female

bullet connectors furnished by the contestant. The calculated motor run

should be clearly marked on the model.

Directions to Waegell Field

Waegell Field is located southeast of Mather Field, near the corner of Sunrise Blvd. and Jackson Highway. From the Stockton area, it’s best to take Highway 99 north past Lodi and go northeast on Grant Line Road, just below the town of Elk Grove. Continue north on Grant Line Road until you cross an aqueduct then bear left at the signal light onto Sunrise Blvd. which heads due north. Cross Jackson Highway at the four-way signal lights. Count approximately 14 telephone poles from the corner on the right hand side. After that you will see a gate leading towards a sheep shed and pen. This is Waegell Field. Rev. 15.2 11-29-12
