is slightly off. The aileron control surfaces have enough torsion flexibility so that damage to the
servos should not occur.
The big 3.3m Yak-55SP is known for very good and crisp 'snapping', and we think that the 2.6m
version snaps even better. It's like an explosion ... and it still stops immediately that the sticks
are released. Be aware of this fact when you try it for the first time. The trick for nice crisp 'snaps'
is to stall the plane with a quick hit of 'up' elevator, and then release the elevator to zero, while
you give full rudder and aileron together. But of course, you know this needs some practice to
make it perfect every time !
You will be pleased to know that your Yak-55SP will not need any mixing at all for perfect knife-
edge tracking. It is 100% neutral when set up as described in this manual. For the finest adjust-
ments as little as 1% maximum might be needed.
Now your Yak-55 seems to be ready for the first flight. Always keep in mind, that you have a rock
solid, but still sensitive, contest tool in front of you, which, if used as it is designed will give you
many hours of pleasant flights. The performance of this aircraft is unlimited, and if maintained
regularly and carefully, you will enjoy it's performance for many, many hours. With this aircraft
you have the potential to move up to the unlimited "cracks", it's up to you now! You can't blame
it on the aircraft anymore....
Have Fun!

We hope that you enjoyed building your Yak-55SP. This manual is one of the first of a new stan-
