Xicoy X45 Helicopter and X45 Turboprop,
two new engines to enjoy!
Xicoy X45H, two stage miniature helicopter engine
This new power unit from the Xicoy stable is a miniature 2stage gas turbine helicopter drive unit to power
0.90cu in (15cc) size pod and boom size R/C helicopters. The unit features a miniature gas turbine
engine producing up to 3.5kw/4.7hp driving a 2
nd
stage turbine linked to a gearbox just like standard full
size practice. This offers a powerful, smooth and vibration free powerplant that can run on regular
kerosene. The sound is totally different from any piston engine, being smooth and steady with a gentle
rush of expanding air to provide a unique driving system unlike any other.
The unit is designed to interchange comfortably with standard 0.90 glow heli engines with considerably
more power available. Standard mountings, shaft attachments, fan and clutch parts may be reused with
minimal modification. The output rpm range matches closely with the benefit of a much higher reserve
torque and broader power curve making it easy match to any similar airframe.
The engine and gearbox unit is extremely small and light and easy to install and operate. It uses the
latest digital control with many additional safety functions developed specifically for this application. The
unit features a built-in constant head speed governor function eliminating fiddly pitch curve programming.
The unit is aimed at experienced helicopter fliers and is equally suited to sport and scale applications
with that unmistakeable scale turbine sound.
Helicopter Conversion Kits
Conversion kits are becoming available to convert standard glow engine airframes such as the Align 90
size “T-Rex700/800” or GoGlow 690 type R/C helicopter to this new power unit and we recommend this
route. (see the Xicoyturbines.com webpage for details of kits and supported airframes and brands).
Conversion kits alleviate the requirement to adapt components and airframe and install this unique gas
turbine power unit as all have already been resolved and included. Step by step instructions plus access
to help and support from like minded helicopter people greatly simplify the process. Installation becomes
a straight-forward assembly task similar to assembly of the helicopter itself.
Xicoy X45TP, two stage miniature TurboProp engine
Xicoy are delighted to offer the X45TP, another 2-stage X45 TurboProp development utilising the 2stage
drive developed for the X45Heli. This unit benefits from very small size and light weight with a high
power output up to 5kw/6.7hp, equivalent to many 50cc piston engines making it ideal to power most
planes up to 2.5m/98” wingspan.
We have introduced this power plant complete with a sturdy mounting enabling it to easily fit standard
firewalls of airframes intended for bulkhead mounted 30 to 60cc petrol (gas) engines. A growing list of
airframe suggestions suited to the engine will be shown in the www.Xicoyturbines.com website.
The Xicoy 45TP is available in two reduction ratings, High and Low:
•
High is for swinging large props at lower rpms for high wing Pilatus PT6 glider tug type
applications.
•
Low is for fast flying sport “Tucano” or PC21 type models with limited ground clearance.
Depending on your planned airframe simply select the reduction rating for the propeller you plan to use.
Choice is if you plan to fly light and fast, or heavy and slow, a bit like the KV value for electric motors.
The gearboxes have been optimised to match each application and can be modified to opposite ratio by
replacing two of the gears, which can be done by customer. This enables us to optimise the performance
of the unit to the power curve of the 2
nd
stage and maximise your enjoyment of the unit.
