Quique’s Signature series

72” YAK 54

The flying manual

Thank you for purchasing the most exiting aerobatic airplane of this class. This 72” YAK

54 is a scaled down version of the YAK-54 TOC model that my friend and partner

Wayne Ulery built and I used to compete and win competitions such as the Don Lowe

Masters 2003, the Free Style World Championships 2003 in Lakeland Florida and 3

place at TOC 2002 in Las Vegas. I have also performed with the TOC model at several

air shows.

I have designed this airplane to perform unlimited aerobatics in two styles of flying,

precision (Aresti) and 3D. The airplane design and set up was accomplished around

challenging compromises required to perform best at the extremes of all aerobatics. All of

the equipment used including, engine, prop, fuel, servos, CG location, rates, etc, have

been chosen with the only purpose to perform well at all types of aerobatics and not

specifically to just one segment. This 72” Yak-54 it is not just a fun fly aircraft type and

it not just a precision pattern airplane, it is both and believe me will do the jobs of both,

of course with the support of your flying skill!

With this manual I want to help you out as much I can in order to in-able you set up your

airplane with the finest control adjustments and best flying conditions under all of the

aerobatic spectrums.

I’ve learned after more than 25 years competing at the international level that setting up

an airplane is almost as important as the design it self in order to get out the very best

performance from the airplane and that is what you to accomplish. To get the very best

performance of an airplane it takes a lot of flying time in order to test it under different

conditions and always there are things better to test and try, so my proposal for you is to

keep you updated at www.somenzini.com with my latest set up configurations in order

for you to get the best performance of your Yak-54, 140. Any new set-ups or adjustments

that I have made and/or tested and find to be an improvement will be posed for you at our

web site.

EQUIPMENT SELECTION

As with any aerobatic airplane the engine selection it 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 dream! 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 72” Yak-54 has been designed to do unlimited, Aresti and 3D aerobatics, so

for this very wide range of aerobatics without question you need a good engine. With
