Thank you for choosing the AirfoilZ Yak54 airplane. We
have taken great care to provide a design and kit com-
ponents that, when properly assembled, will give you
a high quality model with outstanding performance.
While the assembly is not complicated, the quality and
ultimate performance of your model will depend a great
deal on the care you take while building. Please read
these instructions carefully and be sure that you under-
stand them before you start. Take care to assemble the
components as shown and in proper alignment.
This plane has been designed using a Hacker A20-20L
Brushless Motor with a Hacker X-20 Speed Controller and
Thunder Power 1320 mah, 3S Li-poly battery, turning an
APC, 10 x 4.7 Slow Flyer propeller. Other power systems
with similar capabilities can be used. Performance will
vary depending on the specic power system selected.
