Disclaimer: Have fun flying Fun-Fly ... no responsibility taken for
model aeroplanes that disintegrate into bits while following your’s truly’s
instructions.
1. Loops in 30 seconds:
a. run your engine a little richer than normal ... engines
lean out in consecutive loops
b. choose the size of your loops, you can get more loops
by doing slightly longer loops, as the model airplane tends to track and
does not go into the “elevator roll effect”, in other words a sort of “power
roll”
c. get to a comfortable safe heights befors starting
to loop, so if your plane skews out of a consecutive loop routine all you
have to do is get back into it and not waste time trying to gain a safe
height again. Remember the clock starts when you start looping, not when
you take off, find a comfortable height and wind direction.
2. Climb & Glide - 20 second engine run
a. move the CG backwards ... like putting your Ni-Cads
as far back as possible, without jeopardising the plane’s stability. Keep
your RX behind the Ni-Cad if possible.
b. feed in downtrim for climbing
c. fit a smaller propeller, you have to experiment with
this one.
d. for gliding after you cut the engine, feed in some
up-trim and some down ailerons (flapperons!!?). This is lazily (*#?!!)
achieved with computer gear but if not available do not despair, mechanically
pre-set your ailerons on the ground.
e. come in a little high on your final approach and
slip/slide until you are ready to slam the model aeroplane onto the spot
f. if you land close to the spot and you are rolling
away from it, do something to stop the plane rolling, like full down elevators
or full left or full right. Don’t worry about the perfect landing, what
you want is the model to stop nearest possible to the spot without wrecking
it (like I did in the electric glider meeting and then I couldn’t finish
the comp)
3. Take off, Roll, Cuban 8, Loop, Cuban 8, Roll and land in shortest
time
... this is madman desperado material
and only nuts like myself love it, but here goes:
a. like I said this is hot stuff, done low, VERY LOW!
But you can master it! Do a roll on take-off - easy - I know someone who
does it when test flying his new planes - piece’o cake. After the plane
is level again immediately go for a Cuban 8, then continue for another
Cuban 8 but this time you convert it to a loop - again for another loop
but you convert it to a Cuban 8 - followed by a quick roll. Don’t stop
between manoeuvers, go Roll C8 Loop C8 Roll as if it were the one manoeuver,
if this sounds hard, don’t worry. Next time you fly go really high up and
try it. You have nothing to lose, then when you get really good at it,
do it on take-off. Piece of cake.
b. landing ... this is where precious seconds are lost.
Once you’ve finished your desperado task, you must remeber to land the
same direction you took off. After finishing the desperado task you are
still facing in the directin you took off!! Therefore what you do is, as
soon as you complete the last roll, DON’T CUT YOUR ENGINE!! Leave your
engine running at peak revs and make your turn back and just before your
final turn cut the engine ... preferably to a complete stop ... Dead-stick!!
In the turn bring the wing of the plane at 90 degrees relative to mother
earth and pull hard on your elevators, this will reduce the speed by about
60%, as soon as you land and the plane starts rolling on the ground give
it full down or full left or right to make it stop, as the clock only stops
when the plane stops all movement. (Last year I lost 10 seconds rolling
on the ground because I didn’t make it stop and a slightly fast tick-over
on the engine ... that’s why it is better to land Dead-stick).
c. Alternatively, after you finish the manoeuvers and
if you are low enough land straight away. You are still heading in the
same direction as when you took off. It depends how far down the field
you have moved.

wing as Tony did one year at the glider comp |
