Welcome to Chins Chins, my chance to chin-wag.
Each month I will be looking at what's new in the modelling industry, some history from the same month a quarter of a century ago and current Bumpy Green projects I am involved in.

With 2003 now with us, a new year is ahead and a new series of projects will be getting underway. With the restoration of a number of old models planned as well as whatever new models take my fancy. Conversions of current models is also on the cards with a number just waiting for I/C power. So on with the year, I hope you all had a good Christmas and are ready for the coming season with renewed enthusiasm.

Based on the outstanding Caliber 60, and incorporating many of its key parts, the Caliber 30 offers affordable flying for all. Designed with the more experienced flyer in mind, the Caliber can also be adjusted for beginners, making it an extremely versatile machine, straight out of the box. It uses a derivative of the Caliber 60s drive system, incorporating two reduction belts and gears, which dramatically reduces noise and vibration, whilst improving overall efficiency. The majority of control rods are fixed length, making linkage setup easy and accurate, every time. The Caliber 30 is supplied fully ballraced and includes 47 precision ball bearings as standard which ensures a massive reduction in power-sapping friction and dramatically improves performance.

What was going on in January 1977 in the modelling world. Take a look back at some snippets from a magazine of the era.

Beginning the year with the overwhelming success of the new publication 'The Radio Control Guide' the Editor highlighted the 40,000 copies sold of the Propo book and hoped the new book would also become like the R/C'ers bible as the Propo book was before it. 250 pages of thorough detail went into helping modellers from the basics to the advanced. Covering the fundamentals of aircraft flight and control, setting up and trimming a model and selection of aircraft types. Also included a section on boat and cars. Lots of late arrivals were causing concern for the events calendar in the early part of the year with very few clubs submitting schedules in time for the February release and very little time left to make the March edition. Cover picture showed Phil Ramsey with his 1/4 scale Pitts S-2 scratch built from small 3 view drawing provided by the full size aircraft manufacturer. 56" span and flown with Webra 61 power.

Scale Topics examined the pro's & con's of differing aircraft approach speeds. With detailed explanations on the difference between controlled gliding and just diving, how to overcome that terror of aircraft - the stall and advice on trimming a model safely to achieve the perfect approach every time. More changes in the rules of competition decided by the F.A.I. scale technical committee and the S.M.A.E. With additional bonuses awarded to models with multiple wings, multiple engines, flaps and retracting undercarriages with additional bonuses for pre 1914 designs being a hotly debated subject among contenders. Finally more advice on getting a straight non-overlapping joint on tissue & doped models using a very simple but effective technique using a very sharp blade and plenty of patience.

Motor Miscellany with Peter Chinn had the Austrian Hirtenberger HP6-FS on the test bench. Outputting 1.35bhp fully silenced (1.54 unsilenced) it offered 15-20% more power then it's predecessor the 61-F. All pressure die cast aluminium allow casing with steel liner. Centrally bridged exhaust port and fore & aft transfer ports added to the high power output of this well constructed engine.

Featured plan was the Mig 17 designed by Pavel Bôsák of Czechoslovakia. 33" span sport scale jet for .20 size 2 stroke engine and 3 or 4 channel radio. Ailerons being an option. Very well designed model of the Russian fighter which was a development of the infamous Mig 15 and capable of Mach 1. Using traditional built up sheeted design the model flew exceptionally well despite doubts from the club 'experts'. The model was not suitable for a beginner even though construction itself was straightforward the flying characteristics of the model were akin to the real thing - fast and very agile. The front mounted engine with propeller looked odd on the ground - choosing to employ a 3 bladed type but in the air this was all but invisible. The Mig required a very long take off run, again much like the full size and was capable of long graceful loops. No rolls on the designers version as he constructed it without ailerons. Finishing note was that this was a test bed for a larger version flying on a .61 engine.

I wondered how long it would be before this one turned up. Having seen the adverts a few months back it was good to see the arrival of the Middle Phase from Chris Foss reviewed in the sacred pages. 61" span 2 or 3 channel aerobatic slope soarer available as Primary Trainer (dihedral wing no ailerons) or Advanced Trainer (flat wing and ailerons) Steve Bennett tested both wing version and found both to be tremendous fun to fly. Easy to follow instructions also went a long way to making this kit so popular. Lots of sanding was involved in the original version it seems, something reduced by the version updates over the years. I wonder just how many Middle Phases have been sold since it's very first creation back in '76. It must rank as one of the most well known models of all time. There are currently two built and one part finished Middle Phase at Bumpy Green.

Thunderbolt P47 kit from TopFlite was on the building board of Dave Cronin. Stand off scale warbird of 60" span and designed for .50 - .61 2 stroke engines. This size model was a little over 1/8 scale. Detailing features included a supercharger fairing and exit louvres whilst the author added plastic scale undercarriage legs & brass tube fake machine guns in the wings. Incorporation of working flaps is also a must as without them the take off was very long and the landing approach was far too long with the model failing to lose enough speed to land safely even on dead stick. With flaps deployed the model was reborn and took off with a very short run, climbing away in a most realistic manner. Landings were also improved no end reported Dave, who once used to the model was performing slow rolls, loops and stall turns without problems. With no tendency to or waggle on take of landing with full 45º flaps. Not recommended for either novice builder or flyer and although very high quality is also one of the most expensive kits in this size range.

Ashford thermal meeting leads in the club/group shots with the ladies event contestants posing for an afternoon shot, with the event winner, Jan Dunning holding the Cirrus which gave her victory with a 6 minute flight. Rod Walker of Sussex took the overall open event win with his Phase Lift after a 3 way tie & fly off for the trophy.

Flying glider and helpful launcher at the West Medip Soaring Association Crook Peak Cross Country event with a force seven gale blowing and rain lashing the hillside. 35mph headwinds made going very difficult, with only 3 contenders making it to the halfway marker and nobody actually finishing the course. The conditions were less than ideal and the final win going to Sean Bannister with his FAI task model.

Here is another group at Crook Peak holding onto the Wik Kestrel of Arthur Hobkirk during a windy launch. With a severe south-easterly blowing up strong and the launch area some 300 yards from the main ridge it was no surprise that everyone was having a hard time getting around the course.

Finally we see a number of crew at the Teeside Model Flying Club taken by Alan Colligon from his Amigo glider using an externally mounted instamatic pocket camera. Alan enjoys taking aerial pictures of the vast tracts of open moorland in North Yorkshire. His only gripe was having to land and wind the camera manually each time. With aerial photography gaining popularity in both personal and commercial interests more advanced cameras were being fitted to models, with high definition lenses, auto focusing and motor wind becoming common features on many cameras becoming available without excessive costs..

Recognise yourself in any of these pictures, we'd love to hear from you at Bumpy Green. chinman@bumpygreen.co.uk

What a bargain. Bought in a shop clearance sale after moving store location I picked up this Phoenix Impulse at a considerable reduction due to it's slightly tatty box. The model is a very sleek mini pattern ship design, intended for smooth aerobatics and good flight performance. 63" (1600mm) span, all balsa/ plywood construction and supplied with a full hardware pack. Requires 4 channel radio & .46 - .50 2 stroke engine to complete.

That's it for another month,
See you in February

Intersting piece on the Middle phase I tried to upload a pic of mine into the gallery I'm not sure if it worked Its called "follow my leader"
