started out as a happy customer," Derekrecalls of his father's early relationshipwith Stoddard-Hamilton. Along the way,Matthius also had a chance to fly another of the company's products, the GlaStar, and remembers thinking that thekitplane's "flying characteristics wereabsolutely superb for an initial pilot."While the Glasairs were low-slung, composite speed demons, the GlaStar was ahigh-wing utility airplane with a float kitoptional. The opportunity arose to purchase the rights to build a certificatedversion of the GlaStar from ArlingtonAircraft Development, creators of thedesign, back in 1998, and the Stinnesesleaped at the chance. Stoddard-Hamilton, which declared bankruptcy lastyear, recently sold the kitplane rights tothe GlaStar, Glasair III, and GlasairSuper II designs to Thomas Wathen.

according to Derek-the airplane flewthe fast track to an FAA blessing. Thejourney to certification took 16 months,with the first flight of the prototype aircraft taking place in October 1999 andthe delivery of the type certificate thispast April. "You say a few months-itseems like a few years," Matthius commented at the ceremony celebratingthe certification, which was presentedat the Sun 'n Fun EAAFly-ln. The Symphony was certified under EuropeanJARs prior to its FAAcertification, whichhelped pave the way.
A truly new airplaneThough taking an established designthrough the certification process differsfrom starting at square one, the production airplane is decidedly not thesame as the original. Derek points outthat nearly everything on the airplanewas strengthened or made redundantto meet FAR Part 23 specifications.Under the guise of making certificationeasier OMF decided simply to overbuild
the airplane. As a result, very few of theparts are common to both the production Symphony and the GlaStar kit.
While you might think this wouldresult in a heavier aircraft overall, one
major change was made that proved ahuge weight savings and kept the Symphony close to the GlaStar's performance numbers. The original lightweight load-carrying fiberglass fuselageis augmented with a tougher internal,metal-tube cage. The wings and controlsurfaces are constructed from aluminum (same as on the GlaStar). Thecompany was initially faced with havingto beef up the original fiberglass structure considerably to withstand Part 23tests, but instead the lighter shell-andcage combination saves weight for otherairplane modifications. "There weretwo aileron hinges, but specs call forthree," for example, says Derek. It'sworth noting that these three hinges arebeefy ones, and two adequately did thejob before. And the fortification didn'tstop there. The landing gear waschanged to a spring-steel leaf design towithstand the drop test and the repetitive, less-than-stellar landings a trainingairplane is destined to endure. The number of ribs within the wings was doubledto make fatigue tests easier to pass. Theidea: an airplane that's made to last.

impressed with how familiar the Symphony felt, even though it looks substantially different from other production high-wing airplanes. There are several reasons for this high comfort level.
The thick, high wing provides lots oflift and great slow-flight handling characteristics. Stall fences and large,boomerang-shaped vortex generatorstwo on each wing-make the Symphony particularly responsive whenapproaching a stall.
Visibility is good. Part of the cagestructure runs across the windshield,making for a vaguely Piper Cub-like allusion during turns-which may take somegetting used to if a Cub's not in yourrepertoire. However, the side windowsare cut low and the windshield curves
over the top of the cockpit, giving theoccupants a sense of space. Additionally,windows in the cabin's ceiling providevisibility in turns, felling a common highwing demon. The cockpit is wider than aCessna 152's, as comfortable as that of aTomahawk, and fairly roomy for a twoplace airplane. Leather-detailed seatsadd a degree of comfort and style notmatched by many aircraft in this class.
The Symphony has a stick, and it's lowand natural when grasped in the pilot'sleft hand, while the throttle is mounted inthe center of the panel and manipulatedwith the right hand. Control forces arefairly well-balanced. During the first flight,We found the ailerons a little heavier than
the elevator, which seemed odd, but perhaps a few more hours on the airplaneworked out some stiffness. We felt that the
controls were much more evenly matchedduring the second flight (which was ourphoto mission-a formation flight forwhich aircraft controllability is critical).
Familiarity also lies in the fact thatspeeds feel "right" for those of us wholearned to fly in the most popular singleengine high-wings, the Cessna 152 and172. Plenty of power for the Symphony'sgross weight means good climb rates andreasonable indicated airspeeds in cruise:115 knots indicated during our testflights. According to the company, cruising at 8,000 feet with 75-percent powerresults in a healthy 130 knots true. OMFhas positioned the Symphony for the flying-club market, where pilots can learn inthe aircraft and then use it as a practicalmeans to build time and kill time flyingcross-country. At book cruise speeds, the·,Symphony won't elicit many '1\re we thereyet?" thoughts from pilot or passenger.

0-320 gave the best balance of powerand mechanical reliability to the airplane. OMF also settled on a fixed-pitchcomposite propeller for simplicity. MTPropeller, the German manufacturer,also supplies them to the experimentaland aerobatic markets, as well as holding STCs for several production aircraft.
Strangely familiarPilot conducted two test flights, twomonths apart, and both times we were
demo and test pilot for Stoddard-Hamilton who is now working with the Symphony, about the airplane's heritage as aGlaStar. The original GlaStar, accordingto Johnson, was designed to be put onfloats, so its high-lift wing coupled withmore power explains why the Symphony is such a capable land airplane. OMFchose to go with the Lycoming 0-320engine, at 160 horsepower, rather thanthe 0-360 (180 hp) or the Continental10-240B (125 hp), because it felt that the

castering nosewheel has stops so that itwon't turn completely around. Wheelfairings add to the Symphony's cheery,let's-go-fly looks. Some things are inunusual places, such as the fuel gauge,which is found above the right-handdoor. Overall, though, the transition fromCessnas is simple.
Going slowFor the training market at which theSymphony is aimed, slow-flight characteristics are paramount. This is an aircraft likely to be used for instruction,because of its attractive price and docilehandling, and it is an aircraft that doesnot bite. Stall speed is a relatively low 46knots with flaps down, but the big newsis how well the airplane handles down inthis regime. The ailerons remain effectiveuntil the bottom drops out, and still theSymphony feels like it's flying: Maneuvering back and forth during the stallusing the ailerons feels strange, but it'smanageable. According to factory pilots,a burst of power just as the stall occurredwas required for spin entry during flighttesting. The stall warning horn beeps ahealthy 14 knots above stall speed, creating plenty of time to correct a bad situation. This wide margin is a little unsettling on landing to pilots accustomed tothe more standard 5- to 10-knot warn
ing-you still have quite a bit of stick leftbefore the sink begins.
The price of entryThe day-VFRequipped Symphony can be yoursfor $120,000-and
this is a fully certified production model.In contrast, completed kitbuilt GlaStarson the market range widely in price,depending on the accessories and engineinstalled and the amount of time invested
in the project. An informal survey thatPilot conducted in July found severalfrom $79,995 to $115,000. The Symphonyis built in Germany and shipped with thewings off to the distributor, Aircraft Manufacturing and Development (AMD) inEastman, Georgia. Delivery lead time iscurrently three months.
The standard-and pretty basicavionics package includes a HoneywellBendix/King KX 125 nav/com, a Bendix/King KT 76A transponder, and a PSEngineering PM 1000 II intercom. AVision Microsystems VM 1000 enginemanagement system replaces run-ofthe-mill engine gauges, and wheel fairings are also part of the basic package.Two interior upgrades-primarily to theseats-are also available. After that, you'reon your own as far as adding more to thepanel, but there's ample space to do so.
Though the airplane seats but twopeople, the cargo area is generous. Strapstie down bags and a large baggage doorprovides easy access. With two 170pound people filling the seats, 285pounds is left for fuel and bags. Filling thejust-over-30-gallon tanks leaves room forabout 100 pounds of cargo.
For an airplane conducive to trainingand weekend field trips, the Symphonywillhave no problems finding a home. Ja1A
