Glenluce (23rd November) :
We finally got a day out at Glenluce, but as it was VERY short notice, there were very few visitors. However, the weather was fantastic and the flying was awesome. Ally had his Edge back in the air and Murray had come on leaps & bounds since the last event.
This had been a pretty poor year with 3 events already cancelled due to the weather and the forecast was not particularity appealing leading up to the event at Maybole, home of the Ayr & District Fliers. The day started off well enough but low cloud and rain from Glasgow down to Prestwick was not a good indication of things to come. However the flying did get started with Bill Cameron and his YS120 powered Spitfire making the1st flight of the day, closely followed by some of the visiting smaller electric models. A couple of the 50cc models took to the air but low cloud was not in their favour and flying was postponed until later.
The Ayr & District Fliers had promised a barbeque and this was fired up inside the gazebo providing some much needed shelter, warmth and some great food. A very big thank you to James Stewart for all the communication and organising, and to Donald Smith, Robert Crossan & James for manning the BBQ, and a huge thank you to the club members for allowing us to come along for the day; it was very much appreciated and a great time was had.
The lull in the flying was put to good use with Ally holding a Battery Masterclass, explaining the differences in battery composition and which ones are best suited to coping with the sudden and massive current delivery requirements when dealing with 6 or more powerful servos acting concurrently. This was taken on board with one pilot leaving his model on the ground until upgraded batteries were fitted. Further help and advice was forthcoming on inverted spins and when to mix full rudder with zero throttle (e.g. for stall turns).
It was great to see some new faces (Ewan Maxwell with a Precision Aerobatics Edge 540T & DA50R) and Mike McCracken with Goldwing Extra 260 & 3W50), and David Morackas (Ayr & District) with a couple of fantastic own-designs, one with a DLE55RA up front. The usual suspects comprised Ally Young (RC Pilot Yak with DLE55 & Sebart Sukhoi 29 with an MVVS116 twin up front), his son Murray who brought along his Seb Shark and got a few flights in over the day, Neil Chadderton with his Pilot RC Extra 300 with DLE55 and myself with my Pilot RC Extra 300 with DLE55 & AS Power cannister.
At 1:30 the rain cleared and some decent flying was able to get underway with everyone getting enough flying to keep them happy. I finally got the chance with a fair bit of encouragement and help to get the maiden flight done with my Extra 300 at last. Club member David Morakas put on a spirited display with one of his own-design models and Jim Dunlop put on an exciting flight with his Wot4.
So altogether not a bad day although numbers were a bit down. Simon & Chris were working so missed the event, Richard was unable to make it & Iain, Alistair & Stephen were also unable to make this one.
Scottish IMAC round, Castle Kennedy, May 2012 (report & pictures)
West Calder: http://www.highalpha.org/forum/viewtopic.php?f=15&t=3031
11 pilots in total turned up for the day, and were supported by a number of BCF members who came along for the day to watch and help. The site was once again in excellent condition being freshly mown the day before. It is great to see this site improve year on year, and the addition of the spectator seats made life a lot easier than before.
Safety was once again very much to the forefront with numerous people being shepherded away from the propeller arc, the “ready” box being used for starting, and helpers being used for every start, even on the small models.
The weather was great with plenty of sunshine and the wind almost straight down the runway.
Ally Young opened proceedings with his Saito 82 powered Twister and followed with the Python (DA50). Steven Nicol, one of Scotland ’s young hot prospects, gave a great performance with his dad’s ZDZ100 Yak 54 (his own had stripped a servo that morning). All pilots (Alastair, Iain and Steven Nicol, Ally, Richard Copeland, Simon McNeil, Bill Brown, Jim Ewan, Chris Currie, Steven Currie) seemed to enjoy the day with plenty of great flying.
In conclusion we would like to thank BCF for their hospitality and look forward to our next visit.

2007 Review (Ally Young & Tom Laird)
Following the inaugural event at West Calder in September 2006,
Ally & I decided to arrange 3 events for 2007, one in the South,
1 in the North and 1 in the middle. We approached three clubs
(Stranraer, Dallachy, and West Calder) to see if they would support
us, and having got the go-ahead, published the dates. I need to
re-iterate that these events are non-SAA and simply a couple of
guys trying to promote this aspect of the sport. The general strategy
is to have a mix of established fliers who can meet up every once
in a while and show what they can do, and beginners who can get
help and advice. All fliers are SAA or BMFA and Tx control is
adhered to, either via the host club's pegboard or by a Tx pound
in the back of a car or can.
28th April at Stranraer
We had approx 20 pilots for the day, including 1 all the way down
from Elgin, and Nigel Buress from Carlise - hope to see you next
year Nigel - bring a few mates . The weather was great and I think
everyone had a great time. We had an F3A demo at lunchtime and
I can see an IMAC interest emerging so we will probably see some
of that in future as well. Ally brought along a generator, radio
mic and speaker so we were able to get good commentary on what
was going on. Ally also gave a talk on the set up for a 3D plane
including hints on the radio set up. Although we had a selection
of music, no-one used it at this event. Tx Control was in operation
and all trannies handed in to the pound for safety. We would like
to take this opportunity to thank the Stranraer club for the use
of their site.
28th July at Dallachy
Dallachy from the Forth Road Bridge took me 3 hours via Aberdeen.
It is motorway and dual-carriageway almost to Inverurie then a
good "A" class road the remainder. A very stress free run. We
had about 30 to 35 people turn up on Saturday but only about a
dozen or so flew. The wind was pretty horrible, probably about
20mph straight in your face. I think the forecast kept folk away.
Fliers included Grant Darnley, myself, Gordon Buchanan, Ally Young
who flew his Extra, Richard Copeland flew his Bling, and I'm sure
Stevie Wilson flew, but I left the pilots list at Tx control so
can't remember anyone else. Sunday was the Jet day. Alastair Sutherland
(Rookie 2) and Darren (Super Reaper) flew their jets fantastically
well considering the weather was probably worse than Saturday,
and Ally & Stevie entertained the crowd with the Magnum to great
effect. Myself, Lindsay Dickie, Willie Young and Mick Henderson
made up the rest of the pilots. In all 15 aircraft turned up,
5 being jets. This was a great weekend and I'll be heading back
up next year if it on. Again the use of the site for the Saturday
was much appreciated, as were the burgers (I bet you don't get
many of them to a cow).
8th September at West Calder
Another great event with special thanks to Jim McGlynn who cut
the grass, and to Gordon Buchanan for organising the genny and
music. Flying to Enya, or Pirates of the Caribbean is great fun
but not everyone's cup of tea so consideration is required. We
hit the jackpot in terms of sunshine. It was wall to wall blue
sky for most of the day but we had an interesting wind which changed
direction between take off and landing. Again we had a great turn
out of both established fliers from Aberdeen down to Stranraer
but not too many beginners this time. The furthest traveled was
George Korynta from Prague who saw the advert before he left,
but since he was on holiday he had nothing to fly. In total we
had 19 visitors, 16 of whom were fliers. This was supplemented
by a dozen or so club members and a few passers by. The flying
was awesome (I'm not going to mention anyone in particular, but
the 150cc TOC Extra was some piece of kit), and there are links
to the pix on the SAA web site on the "Events" section of the
forum. Bill Cameron went away happy after Steve Currie spent some
time setting up his Yak, and George Petrie got his OTOP's engine
running better with some help from Iain Nicol. A couple of us
got in some Gold practice and received good feedback from Alistair
Nicol. TX Control was well observed with the pegboard system being
used for the non-Spektrum users amongst us. To anyone who has
not been to one of these events I would encourage you to come
along, as you will definitely go home a better pilot than when
you come, as both the safety and flying at this level is very
How to be a Smooth Pilot (Youtube Video)
for 2 elevator servos (Ally Young)
This is what I do to mix two elevators off two channels. Set
up a free mixer like this. Set elevator as the master channel
and aux2 or aux 3 as the slave depending on which channels are
not being used. Set the servo reverse correctly for the elevator
servo so it works in the correct sense for the model. Set travel
adjusts of elevator to 100% and travel adjust of aux3 to zero
both ways. ( This stops the aux3 pot or switch being turned affecting
the mix) When you put in the mix % the slave channel will follow
even with zero travel adjust set. Set the mix to either + 100%
or -100% each way depending on correct servo direction of travel
for your other elevator half. If your servos are accurate and
your linkage geometry are the same on each side, this will give
you evenly mixed elevator halves with no danger of altering it
in flight by knocking a switch or pot. You may need to fine tune
either the travel adjust of the "elevator" or the % mix of the
slave to get both sides equal at the extremes of travel. If you
do it this way, anything you do to the elevator eg. dual rates
( even up to 125%) or exponential will automatically be added
into the slave response aswell, as long as travel is the same
both ways. (You can always at the start set the reverse for your
slave to get the correct direction of movement.) The travel adjust
% and the mix ratio % should be the same. Set at 100% initially.
If you add more it can get complicated!
1 (Ally Young)
Here are a few things to try once you get to grips with it and
the engine is well run in. I'll start with the easier stuff, but
some of it looks really good. You will need a rearward CG but
don't let it get too twitchy. You can test it by fliping it upside
down and checking that it needs almost no down elevatot to fly
level. You will need a good 50 degrees plus elevator movement.
Dial in atleast 40% exponential, 50% or more if you are more comfortable.
Try a Wall into end over end bunts like this. Fly along at about
half throttle, level flight into wind. Chop the throttle right
back and immediately bang in a bucket load of up elevator until
the model literally slams into the vertical, when it is completely
vertical, at the same time, add full throttle and full down elevator.
It will "Bunt" end over end until you release elevator if you
have enough down.
You adjust the wing tips level by small amounts of aileron. You
can actually apply aileron to turn it into a sort of negative
flick. (Make sure you have a bit of height to spare until you
get used to what it's going to do!
2 (Ally Young)
For the progression from your wall into forward flip / bunt the
next thing is to halt the bunt when vertical and hold in a prop
hang before torque rolling a few times. You can also go from the
prop hang / torque rolls into inverted flat spins or upwards spins
by letting the model fall onto its back in a torque roll and then
applying enough down elevator and rudder to get it to start spinning.
You need to keep it flat by applying a little opposite aileron.
If you get the elevator and throttle right you can power spin
Edge set-up (Ally Young)
Here is how to set up knife edge hands free mixing! Fly onto up
wind knife edge at about half throttle max. See what rudder you
need to keep it there. You should not need more than about quarter
stick movement. If you need more then cg is probably too far forward.
The first mix to check is the elevator. Which way does the model
go when on knife edge, does it come towards you or veer away.Remember
you probably auto correct it with elevator subconciously but force
yourself to leave the elevator alone. That establishes direction
of elevator mix required.Start by selecting a basic free mix you
don't need a mix with curves etc. Select rudder as master and
elevator as slave channel. Put in about 5 % elevator mix at max
rudder throw. Remember to set other side to same direction you
don't want opposite elevator deflection with opposite rudder direction!
It is important to select the mix on a switch at first so you
can check by trial and error if it is enough or not enough. When
happy, select mix to "on" all the time. (You will need mix switch
later for spoilerons!) When this is sorted out, adopt the same
procedure with a different free mixer for rudder to aileron. Again
note direction of roll with rudder and start about 5% at max rudder.
The model when sorted should knife edge for ever without you having
to do anything but hold a little rudder in. When sorted, start
by flying long passes with the top facing you. Next push the elevator
at the down wind end and let it come round belly side to you.
Remember you won't have to do anything new, just keep the same
rudder on and it will keep flying. Push and pull on elevator to
maintain heading and adjust height with throttle. At upwind end
pop more down to complete the circuit or pull a little to figure
eight. Start with little wind until you get the hang of it. A
knife edge circle is easier. On a knife edge pass gently feed
in a little down elevator and just let it go all the way round.
Simple! It helps to have a reasonable amount of expo on rudder
and elevator. With 50 to 60 degree elevator travel put on atleast
30 to 50 % expo. Same on rudder. About 20 to 35 on ailerons. This
keeps things smoother and stops twitching that you have to correct
which used brain power which overloads leading to panic and bail
out! Keep it smooth and make it look easy. There is nothing worse
than a nervous twitching 3D model. It doesn't look fluid and in
control. If it looks easy it probably isn't!
