Service Center
We are a fully qualified service center for Jakadofsky Jet Engines in North America
and have been servicing engines from the very first day we started selling and promoting Jakadofsky
products. We carry a complete line of parts including: glow plugs, valves, starter assemblies, clutches,
and clutchbells in addition to all of the standard parts that are replaced during servicing.
Service is part of our commitment when selling Jakadofsky jet turbines and is done in-house by
our certified technicians. We traveled to the Jakadofsky plant in Austria to complete an intensive training
and certification course on performing routine maintenance, repairing engines and calibrating them at the
required servicing interval.
Jakadofsky has been in the aviation business since 1985 doing primarily maintenance,
repairs and inspections of full scale helicopters like the Alouette, Lama and Gazelle. As of 1996
Jakadofsky has been producing smaller jet engines for R/C models and in 2000 they developed a turboshaft
version that integrates a small gearbox inside the engine. The gearbox is completely maintenance-free
providing the most reliable, direct drive transmission of power for use in model helicopters.
From the introduction of turbine power to R/C models, helicopter pilots have been
patiently waiting for this exact development that would allow the turbine engine to be integrated into
our gear driven model helicopters. The PJW-R turbine was the first engine offered and took several
first place wins at the Nationals and the IRCHA Jamboree. Jakadofsky was granted a patent for this
turbine engine design and its entire system in 2002 which passed the AMA certification in the spring
of 2003. Since then, Jakadofsky has continued to release newer models that produce increasing amounts
of horse power with only marginal increases in operating speeds.
The Jakadofsky turbine engines are remarkably well designed. They have the experience with full scale
turbines that has naturally been applied to the model engine.
This RS gas turbine shown here is mounted to a display board that shows how the
engine components work together. On the left is the main fuel tank which is shown as a single tank for
demonstration purposes only. In most installations there are two fuel tanks, mounted parallel within
the fuselage connected with a "Y" style fuel fitting. The main tank then feeds a header tank that deals
with any flight induced air bubbles to provide the fuel pump with a constant flow of Kerosene fuel. The
AECU completely automates the starting procedure by initially opening the Butane fuel valve and igniting
the gaseous fuel. Once the engine temperature has risen, the AECU starts the liquid fuel pump and transitions
the engine to run on the Kerosene fuel. The engine shut down procedure is similarly managed by the AECU
to ensure that the sufficient time is allowed for the engine to cool down before it is actually turned off.
We have invested and outfitted our facility with the necessary tools,
serviceable parts and diagnostic equipment to fully service any Jakadofsky turbine at its regular service
interval or a complete rebuild after a crash. Before any service is performed, we will provide a quotation
for the service and any necessary replacement parts that need to be changed after we receive the engine.
Engine Servicing:
To have your engine serviced, please follow these guidelines:
1. Remove your engine from your helicopter and insert the fuel line plugs that were
originally supplied with your engine to avoid fuel from emptying completely out of the engine. When you
received your new engine, there was fuel already in the lines from the factory quality assurance testing.
2. Pack your engine in the original shipping carton, sufficiently wrapped in foam to
protect the engine in the event that the carrier throws the box.
3. Ship the package to us, postage paid and make sure that the parcel is insured for $5000.00,
in the unlikely event the carrier loses your engine. We will pay return postage for your engine, insured
and shipped by UPS Ground or USPS Priority Mail. Please specify your return shipping preference.
4. After we receive your engine, we will perform an initial inspection and provide a
quotation for the servicing including the standard replacement parts. If after we have completely pulled
down your engine and addition components need replacing, we will contact you with an updated quotation. On
approval we will service your engine, complete an engine diagnostic and fully test your rebuilt engine
before returning it to you.
