Prez sez:
As you may be aware the AGM of CMAC is to be held on the 9th
of March 2021, and will be held at our original venue The Meri-
vale Papanui Club rooms in Condell Ave,. This has been secured
for the AGM and ongoing club events
The AGM is your chance to have your say in the running of the
club in the future, so please attend even if you have not been to
an AGM before; we would love to see you all there.
The committee is currently looking at ways to re introduce club
meetings at the above venue, perhaps in a new format with ideas to encourage our members to attend,
perhaps even a supper - meet, greet and eat. Please contact a committee member with any ideas you
may have or bring them to the AGM.
Happy Flying; Grahame Hart
Addendum: In last month’s Torque, Andrew Palmer’s being awarded the overall RC Scale Champion at the Nationals was
missed out. Evidently, it was mistakenly awarded to the wrong competitor at prize giving.

Lake Station Aerotow
February 12 –14th St Arnaud, Nelson Lakes
Words by Dave Griffin; Photos by Ian Harvey
A very successful aerotow event was flown recently at Lake Station near St Arnaud and
the Nelson Lakes National Park. 25 flies from as far afield as Waiheke Island and Inver-
cargill attended, with some 59 scale gliders of all sizes from 2 metres up to 9m, plus sev-
eral tow planes . Three days of lovely weather with little wind, clear skies and good ther-
mals. The gliders were towed as high as 500m above the grass runway with many able to
climb as high as our NOTAM allowed at 2000’. It is expected this will become an annual
event.
Most of the pilots are briefed by Dave Griffin at this great soaring site.

In consultation with the Soaring Liaison Officer it has been agreed that Free Flight can be flown on Sat-
urday mornings if so desired.
This will allow two opportunities each week to :-
1. Get a morning with little wind and suitable for flying.
2. Fly for NDC and/or NZ Free Flight Championships points.
HOWEVER, this is dependent on contact being made with the soaring group (if present) on arrival to
sort out a suitable area to fly from that will not interfere with their activities.
Both NDC Free Flight and Vintage Free Flight events can be flown on either or both days.
We have one weekend left in February to fly any of the following events:-
Feb/21 108 VINT FF Vintage Power Duration
Feb/21 109 VINT FF Nostalgia Power Duration
Feb/21 110 VINT FF Nostalgia Rubber Duration

Gary’s Hangar 13 By Allan Knox
Some of you may remember Gary Burrows’ bare frame for another Hangar 13. No one wanted it and I
couldn’t let it be thrown out. I figured I could make a useable Vintage Open Texaco competition model
out of it. Gary would approve I’m sure although he was planning much more power from a Saito 46 I
think. This one will have one of the frugal PAW 2.5cc twin ball raced RC motors used very successful-
ly by a number of Texaco fliers. This is all new territory for me as I have always preferred the simplicity
of an OS20FS. Trouble is the OS just isn’t fuel efficient enough for Open Tex, the most demanding
Texaco class.
Gary cleverly designed the airplane to breakdown into many parts . A two piece wing and removable
fin and tailplane as well as removable landing gear. So it is very transportable and is easy to cover. I
seem to have done a lot of re-engineering but a lot of it probably isn’t needed as Gary had done a
pretty good job and kept it light too.
The wing now bolts on, the tail has been strengthened and there is a new engine mount and cowl
among other refinements.
The Hangar 13 is a very old design going way back to 1936. It was originally a 10 footer and had to
make do with just ¼ HP Sparky, typically a Brown Junior. Apparently it needed two wing men on its
take off run and would finally outpace them and wallow into the air where it gracefully climbed out, al-
beit slowly.
This would have been Gary’s
second Hangar 13. The first
one is the Blue beast in this
picture from the club site
( John Ensoll’s fabulous New
Ruler in the foreground.)
It’s a strange looking machine but it’s growing on me. It needs the bright colour scheme I think.
I have the motor half way through running in as I write this. It needs an hour of run in time on an oily
mix. Its doing 5 minutes at 5,500 RPM on a 10 by 6. Once run in I can halve the oil and increase the
paraffin which is the energy. I’m hoping the run time will increase out to 7 to 8 minutes although ideally
I need about 10 minutes and lots of height to glide out to 15 minutes total flight. Only time will tell
whether she will do the numbers.
Thanks Gary for an interesting model. I’ll need you to watch over the first flight where ever you are.
Lost-foam method was used for the cowling.

By Allan Knox Waitangi Day -
Vintage RC flying
The forecast looked good for Waitangi
Monday and since it was a public holiday
we could fly NDC.
Fortunately Lynn was keen so we head-
ed out early to the field in beautiful calm
sunny conditions. Lynn and I both have
new PAWs to run in so he had his test
stand and ran some fuel through his 09.
Mine is a 2.5 cc R/C version in Gary’s
Allan’s 1/2A Skipper. Hangar 13.
An oldie but a goodie. Lynn flew first in 1/2A Atomiser when it
finally agreed to run well. It ran very well
and was soon very high, too high! Then disaster struck as the elevator seemed to quit and, when spinning
it down, the wing broke. We found most of the bits, all bar the wing half which hung up in lift. By the time
we got back to the car Lynn was already scheming out the repairs. You can’t keep a good man down.
I flew my elderly Skipper, now in its 15th year of continuous use. The key to this event is a reliable Cox
Babe Bee and they can be very difficult to set up. The Skipper maxed out as usual.
Next up was E Rubber Tex using my Senior Dart, a 30 inch Comet Kit scaled up to 60 inches. Not a very
stable model being a low winger but it thermals well given half an opportunity. The air was pretty tough.
Not a puffy cloud in sight and a typical anticyclonic day with low lapse rates so thermals didn’t have much
go. Still, the second flight was OK at 17 minutes.

Vintage on 21 Feb
It was great to see some of the crew having a go at vintage flights on Sunday 21st.
John Beresford flew his 1/2A Simplex although that pesky little Cox Babe Bee was being a pain.
We figured out it leaned out as the tank went down so had to be set rich at the start.

On Saturday the 20th of February, several who could make it, turned up to fly ALES 123 and X5J. A
clear sky and a light westerly pushed through some boomer thermals at times, and some of us had
problems getting the gliders out of the sky. I was great to see Keith Elliott now resident in Canterbury,
but his NDC scores still go to Wellington. He flew a rugged Radian (see photo) that flew well when the
lift was around and achieved a MAX in his second flight in ALES 123. Allan Knox and Peter France flew
on the Sunday afternoon in similar conditions. There were some impressive scores in this event, with
the top scores being within a few points of each other.

Keith Elliott with his trusty old Radian—original model
without the screw-secured wings. Despite numerous
repairs and extensive fuselage strengthening, he was
able to fly one of the 3 MAXes in the ALES123 competi-
tion.
If any members wish to fly their Radian in the Soar
Champs on the 5, 6, 7th of March at Tai Tapu in the
ALES Radian or other suitable electric events, enter and
come out and have a go!
At the time of going to press, there is still one NDC
event that has not been flown this month—Class A (6
min duration) to be flown off a winch or hand-tow. If
you want to put in a score, get in touch with the soar-
ing liaison officer, and we could fly on Saturday morn-
ing.
10COMING EVENTS:
Soar Champs 2021:
The National Soaring Champs will be flown from a field between Lincoln and Tai Tapu March
4th to 7th. Fliers are expected from both Islands and will compete in F3B and F3J- both
launched by winch, several electric motor launched events, including Radian, and finally F3K -
Hand Launched Glider on Sunday the 7th. Entry to any or all events is open to all MFNZ mem-

me in times. Pressure was applied by some about
running a larger motor but I didn’t make any chang-
es to my rubber weight and I took out the contest.
The shame for me was that those top guys don’t fly
this indoor class any more. What I am saying here
is the total flying weight should only be 2.2 grams.
Meaning to carry a one gram motor your model
must be only 1.2 grams; not an easy feat.
Open Tissue was also on the NDC calendar for this
month and is too tough to fly two events for a 2
hour meeting. Nev got one time in but Kay and I
ran out of time. I will make an effort to get this
changed next year.
