Equipment Selection - QuiQue's Aircraft 102” YAK 54 Assembly & Instruction Manual

Quique's Signature series
102" YAK 54
The flying manual:
Thank you for purchasing the most exiting aerobatic airplane of its class. This 102" YAK
54 is a scaled down version of the YAK-54 120" a very successful airplane. Winner of
important contest such Don Lowe Masters Champion 2003 & 2004, Free Style Champion
Tucson Shoot Out 2004, XFC Champion 2004 and Free Style World Champion 2003.
The 102" Yak-54 is a pure IMAC performer designed to be a winner when you choose to
fly either precision maneuvers or free style 3-D aerobatics. This airplane is a truly
balanced designed. It showed during my personal extensive test, incredible similar flying
characteristics to the 120" Yak-54 that I used in competition. Very axial rolls, crispy
snaps, strong knife edge, almost no mixing, locked in flying characteristic and very
predictable airplane in all 3D maneuvers. I powered mine with a 3-W 106 QS boxer
engine, 3-W canisters and 3W 26x12 or 27x10 prop for an incredible combination of
power, smoothness and quietness. The total weight of my airplane is 26lbs 2oz. including
the canisters, spinner all ready to fly.

EQUIPMENT SELECTION

Engine, prop, exhaust system.
As with any aerobatic airplane the engine selection is always a key element for the top
performance of the airplane. The engine needs to be powerful enough in order to make
this Yak-54 the airplane of your dreams! But in aerobatic maneuvers power it is not all
that you need. You'll need also good throttle response and transition as well as good
idling. The 102" Yak-54 has been designed to do unlimited, Aresti and 3D aerobatics, so
for this very wide range of aerobatics without a question you need a good engine.
On my 102" Yak-54, I am running a 3W 106 QS, turning a 3W 26x12 2 blade prop or
3W 26x11 3 blade prop or 27x11 2 blade prop here at 900 feet above sea level and under
90 degrees F and about 80% humidity. I have unlimited performance, real strong power.
Because this airplane is light you can also choose a good 85cc or go up to 110cc such is
the case of the BME. 3W 106 or 100cc as well as the DA 100cc and the BME 110cc are
probably best choices for this airplane. It will be your choice, but if you want the best
from this airplane I will strongly recommend a good 100/110cc engine.
It is not necessary to use an engine soft mount. The airplane has been designed to carry
the small amount of vibration of twin cylinder engines. If someone has a 100cc mono-
cylinder I will not recommend it for this airplane.
As we recommend in the assembly manual try to mount the ignition, the battery for the
ignition and switch harness all close each other and as far from the receiver or any other
radio component. The closest radio component will be throttle servo but it is located in
the bottom of the engine box. Please locate the ignition, battery and engine switch as we
illustrated in the assembly's manual picture.
