Notice of 2019 Club AGM

Information from the club secretary:
To all Members,
Please note that the Annual General Meeting for LMMAC is scheduled to be held on Saturday June 22nd 2019.
This will be at 53 Griffen Rd Teralba (club airfield) to start at 10:00 AM.
A General Meeting will be held first and we will discuss the need for electric powered aircraft to have a disarming switch/ system as an added safety precaution., plus other general business.
The AGM will then be held to elect club officials for the financial year 2019/2020.
The meeting will then be followed by BBQ for members and then the field will be re-opened to flying.

Control-Line Flying Now at the Club!

LMMAC has gone back to the future and is setting aside a control-line flight area as part of the flying field.
All budding and experienced control-line pilots are welcome to come and give it a try.
No doubt many of us will be giving it a go!
Here is a picture of the editor’s very first model aircraft.  Maybe it will bring back a few memories (if you’re old enough…)

Flite Test – Great resources for modellers

Whilst on holiday recently I was looking through YouTube and these guys came up on my “What To Watch” feed. I subscribed to their channel and took a look at the site and was really impressed by what I saw.

Their main interest seems to be small electric, depron and occasionally FPV models. They review commercial kits from other manufacturers as well as designing and building their own creations. There is an active forum with over 10,000 members and lots of free downloads.

I like their attitude a lot and I can respect the fact that they have taken a hobby and turned it into something of a career. They’ve certainly got me interested again!

The following information is from their own site:

Flite Test was created for people passionate about flight. Our hope is to create a show for the people that build and fly planes and helicopters as a hobby. They are the dreamers and engineers that get a thrill from the first launch of a maiden flight. The show will personify the veteran and the beginner alike giving them a chance to share common experiences with others, in turn, enhancing the RC community. The goal is to develop a creative outlet that allows us to work in our passion daily. Flite Test is designed to empower our audience. It has just enough humor, technology and information to appeal to the RC flight crowd as a whole. We hope to entertain, educate and elevate our viewers as we move forward with quality content.

I’ll be keeping an eye on their projects and will post any interesting videos or links here.

Do You Have a First Aid Kit?

Being the accident prone father of two that I am, I am more aware than most of the importance of having a First Aid Kit within easy reach at all times.

We had discussed the inclusion of a First Aid Kit at the field in the past and decided that, whilst too difficult to keep one safely on site, it is a good idea for pilots to ensure they have a suitable kit in their car or their flight kit.

Today I discovered in Bunnings Warehouse (Belmont being my local) that they are selling St John’s Ambulance kits at the front counter for $19.95. This seems to me to be an excellent price for a medium sized, 80 piece kit that will cover all the basics in an emergency.

The one I bought looks much like the one pictured so if you don’t already have a kit in the car, do yourself a favour and go get one.

PS – This post is in no way endorsed or sponsored by Bunnings; I just saw it and thought it was a good deal!

Video: The Shuttleworth Collection

Looking for a bit of inspiration for that next big scale project?  At 60 minutes long this is a bit of a viewing commitment but it shows a large proportion of the Shuttleworth Collection in the air, which is something rarely seen these days.

Sit back, relax, and enjoy some of the best examples of vintage aircraft in the existence (then break out the balsa and get cutting!).

 

 

Preparing for the Gold Wings flying test

For the majority of R/C pilots, earning their Bronze Wings and being able to fly their aircraft solo is all that is required for many years of happy aeromodelling.  However, if you wish to fly in competition, at shows or be able to teach others to fly then you will be required to pass your Gold Wings.

The Gold Wings is purely a test of flying skills.  The manoeuvres required as part of the schedule are included to give the pilot an opportunity to demonstrate more precise control of their aircraft throughout the entire flight envelope.  The Gold Wings is not purely a test of aerobatics. For example, if you complete the three rolls by simply throwing in full aileron and completing all 3 rolls inside of 2 seconds then you will probably be asked to do them again – slower and with more control.

If you are thinking about taking your Bronze Wings then you should already know how to fly the required manoeuvres.  This guide is intended to give you some tips on how to arrange the schedule and some tips on what your examiner will be looking for:

The Manoeuvres:

  1. Outside Figure 8 – Flying along the runway heading perform the figure 8 with the first 90 degree turn away from you.  This must be flown with constant rate and altitude turns, balancing all control surfaces for a nice smooth turn.
  2. Inside Figure 8 – Start the manoeuvre on the outfield leg and make the first 90 degree turn in towards you.  Keep the circles smooth and constant for best results.
  3. 3 Aileron Rolls – Keep them slow and make them last the length of the field.  Practice using all controls to keep the rolls axial without losing altitude.
  4. 3 Loops – Remember to balance the power and use the ailerons to keep the loops tracking straight.
  5. Immelman Turn – Make sure that your Immelman finishes with the model flying straight and level and does not start descending.
  6. Inverted Flight 5 Seconds – Make sure to keep it straight and level.
  7. Cuban 8 – Both loops should be equal in size and track with the cross over and roll directly in front of the pilot’s box.
  8. Procedure Turn – Like the Figure 8, the turns should be constant and no altitude should be lost.
  9. 3 Turn Spin – Best performed into wind and make sure you do the full three turns.  Do not be afraid to pull out early if you do not have enough height.

All manoeuvres in the test (except the spin) must be flown twice with each manoeuvre flown both from left to right and right to left.  You also need to make a landing circuit in each direction.  To pass the Gold Wings you have up to four flights to complete all the required manoeuvres.  The ideal though is to complete the test in one or two flights.

Rather than throw your plane into the air and simply try to complete the manoeuvres in any old order.  Think of the test as a competition schedule and organise it that way.  There is nothing wrong with handing your examiner a bit of paper with the order you will be flying and getting him to act as your ‘caller’.  Here is an example of what I mean:

Use the principle of the Aerobatic Box (read this post for more details) the idea is to fly each manoeuvre once one into wind and one downwind.  Land after the first schedule is complete and then, if the wind is calm, take off in the opposite direction and perform the schedule again with each manoeuvre flown the other way.

PA_EXTRA_RdLgTry this schedule (<<< Wind Direction <<<):

  1. >>> Outside Figure 8 >>>
  2. <<< Inside Figure 8 <<<
  3. >>> Three Aileron Rolls >>>
  4. <<< Three Loops <<<
  5. >>> Inverted Flight 5 Seconds >>>
  6. <<< Cuban 8 <<<
  7. >>> Procedure Turn >>>
  8. <<< Immelman Turn <<<
  9. >>> Three Turn Spin >>>
  10. >>> Landing Circuit >>>

The arrows denote which direction to fly the manoeuvre.  Try to make sure there is no ‘messing about’ between manoeuvres – Fly one figure into wind through the ‘box’, turn around and fly the next coming back the other way.

And that’s it!  Practice each manoeuvre individually and into wind before putting them together in your routine.

Good luck – practice makes perfect…

Flying the 'Box' in Aerobatics

visualizing the box

Used in both full-size and model aerobatics, the ‘Box’ is the area in which a pilot performs the schedule.  Although compulsory in competition, the box is a useful way to practice your aerobatics in a safe and controlled environment.

Consider the box as a stage where you will perform your show.  Before you start to fly decide where you want the box to be and use visual clues on the ground to help orientate you.  In the interest of safety when practicing, your box should have it’s lower limit no closer than 100 feet above the ground.

The picture in this post is simply for illustration and the distances given are for full size flying.  If you were flying in competition, the box location and size would be decided for you.  If practicing you will have to decide for yourself.  For example, if I were flying at the LMMAC field I would use the electricity pylon as my centre point and the main east/west runway as the width of the box.  I would also use the runway as the front edge and extend to two or three time the pylon height as the upper limit.

When starting out practicing your aerobatics, begin each manoeuvre into wind as this will make the aircraft more responsive to control and the groundspeed slower as you enter the figure.   Try to be disciplined and turn around the circuit at the end of each manoeuvre before entering the box into wind again for the next.  Of course, if you start flying competition the schedule will require figures to be flown in both directions, but this is for later on!

Using the box to start practicing aerobatics will help to keep you safe and disciplined.  If you ever start flying competition it will be second nature to you and you will have a headstart over other newcomers who did not learn this way.
