David Pound's large 96" Spitfire won the May Scale Day over 7kg military, it has an Enya 1.80, 18x10 master prop, retracts, 6 servos, and weighs 10kg. It is scratch built.
The smaller 66" Spitfire was scratch built then rebuilt by Dave, with Magnum 90 4 Stroke, 14x8 master prop, 6 servos, retracts, and pilot ejecting system, weight 4kg. 
This smaller model was 2nd in the November Scale Day in under 7kg military, Dave had a problem on the landings as the wheel struts were twisting inward causing the model to nose over after landing. This was fixed by filing flats on the wheel struts stopping them from twisting. 
A little novelty is that the smaller model has an ejecting pilot, the pic on the left shows the pilot ejecting, it is near Dave's shoulder.
Some wag was heard to comment "premature ejeculation” but if you saw the way Dave flies the model you would know why any sane pilot would wish to abandon the aircraft.
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

David is well assisted by Jean (see inset) as his pit crew, Jean is seen here with Harry Hubmann's jet pilot helmet 

November/December sees the return to Oz of 2 former Members with formidable reputations, we welcome them back.

Mike Minty (pictured right) has returned yet again from extensive travels in the Americas and the Old Dart, for the past 6 years we have enjoyed Mike's travelogue reports from a variety of destinations. How long is he staying this time? That is like asking "how long is a piece of string?".

Martin Cowen (pictured left) joined WRCS as a child, being the son of Tim Cowen (after whom the Perpetual Trophy for Scale Day is named). His very long association with WRCS was only broken a few years ago when he migrated to Canada. He has since married and has 2 kids and is returning to Oz for at least a few years with some new work developments bringing him home ... he is bringing some nice models back also to play with!

FROM THE WORKSHOP

After reading the last 2 issues of the Mag, we are all aware of the sad fate of Kerry Smith's C47 at Scale Day. 
Never mind, in spite of appearances (see pic) Kerry assures us that the C47 will fly again. Just like the real thing, those C47's are hard to keep out of the sky.

How do you select the correct plug for your application and why?
To do this you need to understand a little more of the theory behind the process. In glow fuel the catalytic reaction is generated between the methanol and platinum only. Castor oil, synthetic oil, nitro methane etc do not generate a catalytic reaction with the platinum. 
Next you need to understand that a certain surface area of platinum is required to generate a sufficient catalytic reaction to keep the internal combustion process going. 
Also it is necessary to allow extra surface area for the reaction to be great enough when it diminishes with the available methanol dropping as in the case at motor idle.
Simply put, cold plugs are manufactured using a thicker wire to give greater surface area to facilitate a greater glow and thus the required catalytic reaction where less methanol is present in the fuel mixture. 
So! More nitro means less methanol which in turn means a greater surface area of platinum will be required to generate the required catalytic reaction. 
Correspondingly a lesser oil content can mean more available methanol and lesser surface area of platinum would be required to generate a sufficient catalytic reaction.
Suddenly it all makes sense! To work out which temperature plug to use you need to know how much methanol is in your fuel not how much nitro or oil. As a rough rule of thumb:
 80% methanol or above use a hot plug . 
 70% ~ 75% use a medium plug . 
 60% ~ 75% use a cold plug. 
 65% or less use a very cold plug. 

Idle Bars and Other Stuff
Again contrary to what many believe the idle bar on a glow plug is not necessarily what its name would suggest. It is in fact to stop any fuel not  vapourised from dousing the platinum coil of the glow plug by dispersing it away from the coil.

Why are plated coils not at good as platinum alloy coils? 
Plated coils suffer from very quick degeneration as the plating breaks down under operating conditions. As bits of plating come off the coil the plug is effectively becoming a hotter and hotter unit until in a comparatively short time it is no longer able to perform its function.
Conversely a platinum alloy coil will still degenerate but as it is platinum alloy throughout, the surface remains as platinum alloy and the plug continues giving much the same characteristics for quite a very long time. 

After crashing his C47-Dakota on Scale Day, Kerry Smith had trouble locating his aircraft. In spite of a lost model device installed, he found that the tracker had not been turned off, flattening the battery!! Unfortunately his model found the only area of a rockface that was not covered by vegetation. OUCH! 

Most readers realised that Col Simpson's Mustang was a P51 (and not P49) and that GF's "bear" was spread all over Shepparton (and not Adelaide)  as printed in the Nov Mag. The problems were corrected before the Newsletter was posted on the Net.

Is Garry Welsh's middle name "Hawkeye"? Often he has assisted your Editor in correcting the many mistakes that this amateur publisher makes. Thanks, Garry

Des Rim, Garry Welsh and Garry's DR109, Trolley, Corsair and Stampe made it into the Gary Sutherland “Mammoth Scale Down Under” atricle of Shepparton 2005 in the Flying Scale Models mag December 2005 at the top of page 23. 

Early Christmas decorations at the field? Assorted cables, wires, plugs and servos hanging from the trees!! NO, just Peter Papas' plane after he absolutely shredded it flying at full speed into the trees.

PLAN PRINTING ON TIMBER
From the plan, photocopy the parts required to be cut (make sure there are no distortions). Lay the copies onto the timber face down and use a hot iron on the back of the copy to transfer the sketch (the photocopy toner is made of carbon which is reactivated by the heat from the iron).
