At the bottom of page 9 a downloadable Power Calculator is announced but I can't find it. Sounds very useful, any ideas where it is on this site?

Thanks

Hmm.

They say in order to see it, you must cross to the Spark Side.

David, don't bother it's pretty unrealistic. [IMO]

I just downloaded it and put in the figures for several of my models (aerobatic and vintage) and found the results surprisingly close.

I'm surprised by that Pat. I have designed several electric conversions around this method, thay all fly well with sensible power levels and durations. Interestingly on one conversion that I blogged on here the method agreed well with results from Ecalc. Indeed when actual tests with a power meter where performed the power output this method predicted was significantly more accurate than E-calc's figure.

As no large and questionable assumptions are made in the model I can't honestly see how it can be "unrealistic" to be honest. Its idea of how much power is "enough" for different model types might be different from yours - but that's a question of preference not realism surely?

Is there anything similar about for glow and petrol powered models?
