Designedto be more robust than the Druineand thereforemore suitablefor club flying. the CondorprototypeG-ARHZfirst flew in May 1961with b somewhat underpowered75hp ContinentalA75.

Havingcompletedhis first solo on 9-Al9lin 1974,Alan owned his first Condo[ G-AVXWfrom i977 until 2OO5 any at all since'1974, its attrition rate nas beenvery good. There have been a smallnumberof fatalaccidents. two of which involvedglider towing. Althoughusedas such,the Condorwas not a qood choiceof glider tug. They were all built at CroVdon,and I believe their manufactureduring those years was the last aeronauticalactivitv at Croydon. They'dalreadyclosedthe airfieldby then, so were havingto take the Condorsout to Redhillto test them."

Recentlysold,'XW is being rebuilt and shouldsoon be flying again. Alan is now concentratingon his current Condor,G-AXGZ, a D62B modelthat he has ownedsinceJanuary 2002. "lt all started when I was eleven,,.he muses,eyesgazingat Rochester's capaciousmain hangan "l usedto come up here to Rochesterand at that time the ConCorwas the basictrainer. It seemedto epitomisewhat light aeroplaneswere all about. They'djust replacedthe Tiger Moth with Condors and I quicklygot to likethem. When I was at schoolmy friend'sfather was learningto fly. and he took me on my first flight in a light aeroplane,a club Jodel. I ended up doing part of my trainingon Jodels,cross-countryflights and so on, and the other chunk was done on Condors. "They didn't maketoo manv Condors but consideringthey haven'tmade Alan'sCondonresplendentin its orlginalfactorycolours,has a fuselage of plywoodconstructioncovereotn Medapalinfabric. lts wing is standard with a plywood-covered D-boxon the leadingedge,and Ceconitefabric coveringelsewhere."There have been no problemswith the coveringand no corrosion,"reports Alan. "They're good,long lastinqaeroplanes in that respect- not as prone to wear and tear as some types seem to be. Thev werebuiltusingmodernglue and the woodworkhas consequenfly givenverv few problems." The older French-builtaircraft were not put together in the same way and were far more likelvto suffer from woodworkproblems."When the Condorscamein to replaceTiqerMoths there were a lot of doubtersthat didn't expectthem to last ien minutes. In fact the Condorhas provedfar more robust than the TiqerMoth. tt'sjust a pity they werebuiltin suchcomparatively low numbers. "When I started flying,the Condorhad begunto establishits reputationand it wasactuallyquitehardto gr,.iine instructorsto take you up in .: i-iger Moth. In comparison with ti ,..i.r;ndor they wereconsidered unrellsi,te and uncomfortable. Althoughthe club had two Mothson the fleet.irjr-,e was normallyawaitingrepairfi+rit one of the many accidentsthe tvpe sufferedin club usage." Thouqha few Condorsrarere upgraded to D62Cstatus and given the more powerfulengine,the slightincreasein performancewasoffset by higher fuel consumption. "The aeroplanehasa reasonably good short fieldperformance in any case, and the biggerengine.iust givesit a Iittlebit extra. The prototypeoriginally had a smallerenginebut wasseriously underpoweredbeforeit was re-engined. The aeroplane'sAchillesHeel,however, is that it only hasa 69lit tank,and the l3ohp enginejust sucksthat up in no time. That'swhy I find it preferable to havethe 1O0hpversion.lt uses 48 Today'sPilot March2006 lir! Rollason D62B G-AXGZ resplendent in its origiral factory G*A XtrE fus ler": Tfte undercarriage shortened aftor with longerlegged earliermodels. Lirr Thefuel easilyaccessible, about 22lit per hour,so its maximum enduranceis about three hours. That wouldalmost leaveyou with a dry tank. The lonqestI've ever done in one stint is two hours and 40 minutesover France,Oil burn, however,is negligible. It doesdrip a bit, but that seemsto be a characteristicof this particularengine rather than the aeroolane." The gear is not retractablebut is quite robust.just likethe rest of the aeroplane. Designedas trainers.the aircraft will put up with plenty of firm landings, and the fact that 36 out of 49 are still flying is testamentto their worth. Most Condorsin the UK have rackedup at least5,OOOhours,with those usedas glider tugs likelyto havesufferedthe most. "The one I first went solo on had a patchalongthe right hand side which was causedby a pandacar skiddingon the grassduring a policeexerciseand rammingthe aeroplane,"Alan recalls. "Not eventhat has stoppedit." C O N D OERV O T U T I O N Smallin stature,one thing that strikes the casualobserveris how low the aeroplanesits on the ground. Despite the limitedproductionrun. Condors have.evolved over the years,and the undercarriagelegson Alan'sD62B exampleare as short as they are for good reason. "Some of the earlier oneshad longer undercarriagelegsand those legswere situatedfurther backin the winq,"he says. "Thosewere much more proneto standingon their nose, and every year we'd havea prop break on one of them. Theyalso had a much shorter stick in them, which we found quite unpleasantto use. 'As the aeroplaneevolved,that undercarriagegot shorter and was moved forward" That madethe aeroplane mucheasierto handleon the ground, and it's virtually impossibleto get a later one to qo over on its nose. There is still a lot of similaritybetweenthe first one and the last one,but that said, it is difficultto find two Condorsthat are exactlvthe same." Alan has flown many Condors,including the prototype,which is still extant today and is currently being rebuilt. "lt \/as an interestingaeroplanebut it felt verv differentto the one I'm flying now,"he recalls."lt was grossly underpoweredfor a start, and I believe there were some problemswith trim characteristics, all of which were soon ironedout on both the prototypeand subsequentCondors." Over the yearsRollasonassessed variousmodels,shorteningthe fuselage and applyingdifferentwingtips. Alan's Condorhas cut-off flat plate wingtips, whilehis previousexamplehad a conventionalwing bow. Thereare many that understandably assumethe changein wingtip style was done to improveaerodynamicefficiency,but Rollasonin fact changedto flat plate iips simplybecausethe companyran out of parts. lt had beenusingTiqer Moth wing bows until then. A few Condorsendedup with glassfibre wingtips,a differentmodelagain. "One definiteimprovementmadeover the yearshas beenthe brakes,"adds Alan. "You'resupposedto use the brakesonly for parking,not for slowing you down, but in realityyou can use them for slowingdown in later models like mine,becausethere is no longer that tendencyto go over onto the nose. EventhoughRollasononly madea short run of Condors.it's fascinatingto see how the designdevelopedduring its lifetime." In decadesgone by,Condorowners went througha phaseof painting their aircraftin what might politelybe termedindividual and unusualcolour schemes.WhenCondorswere regarded as everydayaeroplanes,ownersdid everythingthey couldto changetheir appearance.With the designnow over 40 yearsold, it is reassuringto see so many now revertingto factory colours. Alan'sCondoris largelyyellowwith blue trim, a schemethat seemsso much more naturalthan the swirlsand stars appliedto many others in the 1970s. The majorityof Condorscamefrom the factory in yellow and buyerscouldalso havethem in blue,red or white. 'Another featurethat I think is worthv of praiseis the cockpit,"saysAlan. "lt's got a properblindflyingpanelusing post-warmilitary surplusinstruments thai are either driven from a venturi in the earlyonesor a suctionpumpin the later ones.
