The newly developed JetCat P220 RXi, not only has
an integrated brushless and fully encapsulated fuel
pump, but also features a brushless starter / generator
system!
Note: Battery not included.
The rotor of the fuel pump is running in the fuel,
therefore the otherwise necessary shaft seals can be
omitted. The starter / generator operates completely
mechanical contact free to the turbine shaft. Therefore
the “coupling” of starter to engine rotor is resistant
to wear and dirt (no slippage of the starter clutch by
oil/dirt, no O-ring wear possible)
The specially designed “non-contact coupling
system” (patent pending) also ensures that the brushless
generator, compared to the engine rotor, only spins at
comparably low rpms (well below 10,000 1 / min). This
ensures a very high reliability and durability of the
entire starter / generator system.
Furthermore, the JetCat P220 RXi has been
optimized for a minimal system weight. The housing is
made of thin-walled laser welded stainless steel. The
entire engine, including integrated brushless pump,
valves, fuel filter, generator and charging system only
weighs 1850g.
In conjunction with the new “JetCat BMS system”
(BMS=Battery Management System) lighter and smaller
receiver batteries than previously required can be used.
The receiver batteries are constantly recharged via the
BMS system as soon as the engine is running.
Never charge batteries, only refuel in the future!
After starting the engine, the engine battery is
recharged via the generator with high power. The engine
side electronics controls the charging current / voltage
automatically.
The engine battery is also charged if the engine
runs at idle. The optional JetCat BMS system can be used
to also recharge the receiver batteries. In this
configuration, the BMS-system ensures that the receiver
batteries are always fully charged upon the next engine
startup. The charging of the receiver batteries will
continue until these are completely full, even if the
RC-system of the model should have been powered down.
