Progress - What Progress?

Have you ever noticed how contradictory the model aircraft hobby can be? If you decide to spend the day on a building/rebuilding/repairing binge then the weather will be so damn good you just have to grab something and go flying. Conversely if you spend hours charging batteries and pre flighting models, getting all your gear together, ringing up mates to meet at the field then one hour before you are ready to leave for the field the damn wind will come up to something like a force ten gale or the clouds will roll in and a thunderstorm worthy of end of times will split the heavens.


Anyhow of late Murphy (of Murphy's Rules) and I have had a few altercations and in spite of a hanger full of models I'm down to three that are flyable. One is a high wing trainer that has more years on it than I do, for Aussie fliers they may recognise it as one of the original tail dragger Aeroflyte Hustlers. (Yep, I'm THAT old!). The second is an equally ancient P47 Thunderbolt and the third is my first attempt at a multi engined model, a Magnum. All the models could probably qualify for the old age pension.


How did I get in this mess? Well - errr. I like to build, from scratch, which means I start off with a plan and a heap of timber and go from there, no ARF @#$%! things will ever pollute my model collection and any one who swears in my presence by mentioning el*ctr*c THINGS will be banished to the down wind end of the runway. So the quandary is I have all these 'works in progress' and the bloody sun keeps shining and I want to go fly. The problem is this equation:-


Models ready to fly                  Models under construction                Number of crashes             Hours in the day
-----------------------          x             -----------------------------------         x       ---------------------------           x    -------------------          =  CHAOS
Models  flown                      Square root of balsa supplies           recoverable bits                       available hours


I'm sure many modellers are familiar with this equation and some may even know the corollary where chaos is equal to the reciprocal of flying skill!  I still maintain that the latter is only a theory and has not been proved so it is not written into the laws of model flight - YET.  Then again there will be some smart arse who thinks my mathematics might be the problem in the first case.


So for those hardy souls who are foolish enough to follow my rambling on this blog here is an update.

• I've finally found a set of scale wheels for the Piper J3. Gee they look good and the model is now almost finished.
• The new fuselage for the float plane is finished and I'm fitting the motor and servos.
• The Harvard has the motor and retracts back in and I'm building a scale cockpit fit out for it.
• The model that hit the rocks is gradually being rebuilt.

The 'REBUILD' wall!

Those lovely Cub wheels

CHAOS!

I've just bought a set of plans for a DH2 off eBay. I'm in love - all that timber and wire - and  a 60 pusher for power! SOB!! Another model I just have to build

A Book Review! ??

Yep a book review. I recently borrowed a book from the local Library Titled Aircraft Workshop. It is written by A Kiwi named Kelvin Shacklock and although it's a few years old it is probably one of the best, and most practical, books on model aircraft I have ever seen. I've been building, and flying model aircraft for well over thirty years and I have a fairly extensive library of Model Aircraft titles but I saw this one on the shelf at the Library and borrowed it more out of curiosity than anything else.


The book is near enough to bloody brilliant! Hold on - what do you mean literature? binding? layout? What do you think I am? A bloody book critic? I'm an Aeromodeller mate, you know, I build radio controlled miniature aircraft and I fly the bloody things. So I'm interested in what the book gives me in the way of tips and techniques on building and flying my models. If it has a few plans of interesting scale models and easy to understand instructions all the better. This one has the lot! Everything from your most basic chuckie (if you build model aircraft you'll know what a chuckie is) right up to a rip snorting, all singing, all dancing 1/5 scale Mk XIV Spitfire, and believe me the exhaust set up on that one is something I'll be copying or  adapting to some of my other scale models. The plans are great and follow a progression from the most simple chuckie, and a rubber powered J3 Cub right up through a basic RC Trainer to some very interesting scale projects including that absolute ripper of a Spitfire. All the plans in the book are one quarter full size and can be copied and enlarged to full size.


The instructions are in plain bloody English (not bloody Chinglish) and cover everything from concise and extensive construction notes for each model as well as information on trimming, enlarging plans, building baseboards and even a bit of basic model aerodynamics. I could rave on a lot more but if you can find a copy grab it, it's well worthwhile. Hereunder the details:-

That Damn Electric Invasion

For most of my life the traditional default power source for model aircraft has been the  two stroke internal combustion engine. Powered models were admirably supplemented by rubber power and solid fuel rocket engines that were mostly of the JETEX brand. Over the last few years there has been a concentrated attack on our traditions by the advances of technology. 


Four stroke model aircraft engines were the first to appear on the scene and at first were an expensive, underpowered but lovely sounding alternative. In a few short years we have seen refinements in these motors produce astounding advances and the increase in power output, and the reduction in price, has seen their wide spread adoption, particularly in the larger scale model arena.


Next was the appearance of large four stroke multi cylinder engines. Marvels of miniature engineering and, many modellers thought, to own one was almost worth dying for. The appearance of multi cylinder RADIAL engines was just one more reason to build that huge model with the great gaping round cowl. If you have ever seen a large scale F4U Corsair or a big P47 Thunderbolt equipped with a radial engine you will know what I mean. With the appearance of the Chinese manufacturers, and the attendant reduction in prices, even these miniature marvels are within the grasp of us poor mere mortals to possess. On top of all this the Japanese O.S. Company brought out the the IL300, a four cylinder masterpiece based on the old Gipsy aircraft engine. Most modellers thought we had died and gone to heaven.


Of course the two stroke motors had benefited from all this technology as well. I nearly choke when I run up one of my larger vintage motors and see a modern two stroke half or even one third it's capacity produce twice as much power. Modern two stroke motors are lighter, more compact, better designed, more powerful AND cheaper than their equivalent counterparts of even twenty years ago.


So everything was looking sweet and we old dinosaurs sat contented with our oil soaked rags, our methanol and our nitro. Then one day a younger member turned up at the field with an ELECTRIC powered, ALMOST READY TO FLY, MOULDED FOAM model of a Spitfire! The damn thing was still in the box he'd bought it in!  A Triple effrontery to us balsa stick and nitro devotees who built all our models with love and dedication from scratch. Then he proceeded to assemble it on the spot. The mutters of disgust and the jeers of derision would have defeated a lesser man, young or old. Never the less he had it assembled and ready to fly in less than fifteen minutes.


The comments from the old lags flowed like water off a duck's back. Followed by howls of "It'll never fly" and "It will crash and all that foam will crumble" he launched it into the air. There was a stunned silence! The damn thing flew! Fast! And he pulled all the maneuvers that you would expect from a radio controlled model of the legendary Spitfire. After only five minutes the motor quit and he brought the model in, dead stick , to a perfect three point landing. We wouldn't admit it but we were impressed. Of course we found reason to roundly criticise the model. The batteries were flat after only barely five minutes in the air and a Spitfire that flies by with nothing but a whisper was definitely not kosher for a War Bird. We pronounced electric power dead before it had even had a chance to grow up.


That was  nearly five years ago, that same young modeller is now in his mid twenties and constantly wins our scale day trophies with his electric powered, multi engined, sound system equipped, giant scale models. We scratch building, nitro engined old dinosaurs sit away in the corner of our pits and while sniffing the aroma of our Castor Oil soaked rags and discussing the relative merits of cross grain as opposed to radial grain balsa mutter terrible incantations to banish the squadrons of moulded foam, electric powered, trainers, pylon racers and scale war birds flying triumphantly around the skies. Sometimes I just want to cry.
