There are at least two energy/weight proposals Iâ€™m aware of (by Germany and the USA) that are quite similar. There is probably a good chance that others would pen similar approaches. Hopefully CIAM will adopt this approach â€“ as it creates a true level plying flied across all F1Qs, small and large, locked and auto surfaced, unlike any F1 class we have. The nice thing that each model would have its own motor run and all could reach the same potential altitude. The more efficient models would get higher, with better odds of winning.
As noted before, motor runs can be calculated using a wattmeter to back out the average wattage of a specific motor run. Average wattage multiplied by the motorâ€™s time is the energy used in watt-seconds or Joules. Dividing it by the models weight will give a ration, between 3 and 5 watt-sec/gr (the value will be selected by CIAM.) The higher/lower the watt-sec/gr the hotter/colder F1Q will become. With a high watt-sec/gr ratio F1Qs will outperform F1Cs, and a low watt-sec/gr ratio F1Qs will resemble power models from the 60s. (In effect, customizing the event.)
Energy Limiter (EL) or programmable EL (PEL) is just a black box that figures out the motor run all by itself, and might inform the e-timer that the motor is on the verge of being shut off so that things remain synchronized (as discussed earlier).
The American proposal calls for the coexistence of both methods. Lower powered models (100-300 watts) could back out their (longer) motor runs by using wattmeters. Powerful models (500-700 watts), with very short motor runs, are likely to use PEL as a way to avoid timing errors and pushing the envelop. And if CIAM adopts this dual approach, most of the fliers in the first group will just continue using their 10-15 second motor runs. (Forget the PELs!)
