Less
Smoke/More Power/Superior Mid-Range
For years heli pilots associated good lubrication with large
amounts of smoke, this is simply not correct. Oils used in R/C fuels
can be of different viscosities (different thicknesses or weights)
some fuels use large volumes of less viscous (thinner) oil with the
idea that since the oil is thinner the engine will be able to
accelerate quicker and the greater volume will make up for the
reduced protection that the less viscous oil provides. In a few
respects this is true, but the penalties outweigh the benefits. By
using the less viscous oil a much greater volume is required for
lubrication, this in turn reduces the amount of burnable fuel
available (the oil does not burn) and thereby reduces power. Usually
the result is the pilot over leaning the engine trying to extract
the power. The larger volume of oil also produces excessive smoke
(carbon) during combustion. WILDCAT uses a more viscous oil at 18%
volume. This oil better protects the piston with a stronger shear
strength and load carrying capacity lubricant. It also provides for
a better seal between the piston and the sleeve, this in turn allows
for higher compression due to the reduced blow-by ie.. more power.
Because we use a more viscous grade of oil we can use the 18%
volume, this allows more methanol and nitromethane (fuel) for the
combustion process ie... more power. By using a higher viscosity oil
we can use the recommended amount that meets and exceeds most
warranty requirements including the popular OS heli engines. Using a
more viscous grade of oil also provides for our next benefit, better
heat removal. In straight forward engineering terms the greater the
viscosity the higher the heat capacitance. In English, the thicker
the substance the more heat it will absorb in a given amount of
time. The higher viscosity oil can simply carry away more heat from
the engine. Once again, this provides for a cooler running engine
that will make more power and transition better. Last but not least,
Klotz adds a fragrance additive that they have been producing for
years for high performance racing motorcycles this gives our fuel
that distinctive good smell and does not distract the judge from
what he should be doing, watching your chopper!
With the help of the experts at Klotz Performance Products (The
leaders in model lubrication technology) and the experience of
expert helicopter pilots WILDCAT FUELS produced a superior
helicopter fuel for the 21st century Helimix. |
