[NSRCA-discussion] Question.

[Dave]

"Power" of an IC engine is generally related to displacement...but not
exclusively..more RPM at the same displacement equals more power.

 

Electrics are limited on voltage only.there is no limit on amps.both
contribute to power, so there is no limit on electrics.

 

The limiting factor in pattern is really the noise limit, for both IC and
electric.

4. Model Aircraft Requirements: 

4.1: Propulsion source limitations: Electrically-powered model aircraft are
limited to a maximum of 42.56 volts for the propulsion circuit, measured
prior to flight while the competitor is in the ready box. 

 

I see Electrics have a "Displacement" limit, why are they limited and the IC
engines not?

 

I also see they must be checked in the ready box prior to each flight,
anyone ever have this check done? Even at the worlds?

 

Or is this another ignored rule?

 

Tim
