 FUN-FLY HINTS

.... by Tony Vella
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.

Editor:  ... and don’t get your feet tangled around your wing as Tony did one year at the glider comp
