it more in an attempt to match RPMs exactly, remember 'Golden Rule 1'. The
likelihood is that one or more may need to be made richer when you do the nose up
mixture test.
When all is well, shut down all the engines and take a breather!

Control Setup

Make sure you have set the control movements according to the information given in
these instructions. Double check the CG position at this time also.

Mixing

1) Program 40% rudder to aileron mix as a permanent mix (left aileron gives
left rudder). This helps to stop the tail 'hanging' in turns. You can fine adjust
this to cater for the differing torque of your engines compared to our test
model. It is actually slightly different in left and right hand turns but this is a
good starting point.
2) Program 10% down elevator to flap mix as a permanent mix. This will help
prevent the nose going up when selecting flap. If you are not using the wing
tanks and have more flap available then this may need increasing.
3) We strongly recommend the use of a 'failsafe' function on this model. In
some countries this may be a legal requirement. Always set the failsafe on the
day of flying. If you program a turn as the failsafe setting, make sure it is away
from spectators for the take-off/landing direction of the day. Throttles should
always be fully closed.
4) Many multi engine flyers fit a gyro to the rudder to help in an engine out
situation. It is not necessary but might help. It needs to be positioned on the
yaw rotation axis ie. Close to the wing spar and may need to be set with a very
high gain.

Flying

Have a word with your clubmates and try to get a flying slot on your own. This will
not be difficult as they will all want to watch anyway! Go through the usual pre-flight
checks and start your engines in the sequence advised earlier. Did you fully re-fuel all
four engines? Remember to check your failsafe is working.
The C-130 is fairly straightforward to fly once airborne, but the take-off and landing
require some new techniques to be learnt. This mainly revolves around throttle
handling sequence and can be best summarised as;
'Golden Rule 2' –
1) Inners up first followed by outers
2) Outers down first followed by inners
