Initial offering will consist of ready-to-use Buzzcoil PC board assembly complete with pigtail leads.
To complete installation just follow the wiring diagram using your model coil and battery.
We suggest using the Exciter model coil and a miniature sealed lead-acid battery, both which are
available through us if desired.
Later offerings will include several sizes of turnkey solutions complete with buzzcoil, battery, and coil
all contained in a custom designed scale wood "battery box". This new Buzzcoil Battery Box offering
provides an ideal solution for model hit & miss engines. Buzzcoil ignitions provide a "shower of sparks"
and have proven ideal for low rpm hit & miss model engines where fuel mixtures are often inconsistent.
Our new Buzzcoil Battery Box uses an electronic buzzcoil instead of the old style mechanical version
found in a Model T Buzzcoil. Since an electronic buzzcoil requires far less electrical current than
an old mechanical version, battery performance is excellent. In testing this summer we successfully ran
our Tochtrop Economy model engine for 36 hours straight using the electronic buzzcoil with no drop
in ignition performance.
The main advantage of the electronic buzzcoil, however, is the ability to build a smaller installation
package than is possible with a mechanical buzzcoil. For larger models this may not be an issue, but
for those with small scale models the small form factor of the electronic buzzcoil will be quite helpful
in creating a scale display model.
Until now successful ignition systems for small model hit & miss engines have been a bit of a "love/hate"
relationship. Traditionally, either a single spark system is attempted using a converted or model coil,
or alternatively an old automotive "Model T" type buzzcoil is used to provide a "shower of sparks" to the
combustion chamber. Both solutions have disadvantages for model hit & miss engines. Single spark systems
(transistor ignition module or points and condenser) function in an acceptable manner so long as everything
else in the engine is tuned properly,unfortunately most model hit & miss engines suffer from varying
fuel/air ratios in the combustion chamber. This often results in misfiring or failure of the single
spark to ignite the fuel/air charge in the combustion chamber. Old Model T type automotive buzzcoils
provides a strong shower of sparks in the combustion chamber but these type buzzcoils are large in
size and require a large battery for operation, this makes for an unsightly display.
No more need for a large automotive buzzcoil or large sealed lead battery to power your hit & miss engine.
Using efficient electronic buzzcoil technology and minature sealed lead-acid batteries, scale installations
are possible. For the turnkey battery box offering there will only be three wires to connect, one wire to
engine ground, one wire to ignition points and one lead to the engine spark plug.
