In 1983, the Hughes 300 was sold to Schweizer Aircraft and is still available as the Schweizer 30 0. Several years after the successful launch of the Hughes 269, 300 series (TH-55 Osage for the US Air Force), during the peak production period, when more than 1,000 such helicopters were produced per year, the Hughes model line was supplemented by the Hughes 369 (MD 500 C) - in civilian.

Robinson R22 vs. Schweizer 300CBI

Schweizer 300 Maintenance Manual

'So, which Helicopter did you learn in?'

It's a common question, and one which the majority of helicopter pilots will answer with either 'Robinson' or'Schweizer'. Admittedly some of you will be stuck with whatever your local Heli school has to offer but occasionallyyou find schools with both and therefore, a choice!

I say majority because you can learn to fly in any helicopter you choose,so if you can afford to pay the hourly rate, or indeed own a Eurocpter EC120 or a Bell Longranger (pictured), there'snothing stopping you from learning in one! Just remember though, if you do, in JAA countries (Joint Aviation Authorities) you will be restricted to flying that model only, other helicopters will require a 'type rating' qualifying youto legally fly them, and with an hourly rate for rental of between £350 and £650 for the bigger 4 to 6 seater helicoptersyou're going to need a fat wallet to pass your test! I didn't have this luxury and therefore easily narrowed mychoice to the R22 or the Schweizer...

Don't get me wrong, if you can afford to fly a bigger heli than this I would merely recommend that you flywithin your perceived personal limits, affordability and skill level, and the more hours you do in the same type of helicopter the better you will be at flying it. Learning on one type and then jumping straight into another has it'sown associated risks and should be done with a certain amount of care and respect for the new helicopter you are flying. Always remember, as a helicopter pilot, each and every time you fly, you are responsible for your own safety, that of your passengers, andanything that you have the potential to land on, be it by choice or forced emergency...

The purpose of this page is to compare and contrast the Robinson R22 Beta II helicopter with the Schweizer 300CBihelicopter. Both are popular as trainers, but there are advantages and disadvantages to each manufacturer's helicopter.

The Robinson R-22 Beta II

The R22 is the most popular civiliantraining helicopter in the world. The Beta II is the newest and most powerful model of the Robinson 2 seat helicopter so far produced. Robinson has built over 3800 R22s since their certification in 1979. The pros andcons listed here apply only to the Beta II model and not to earlier Standard, HP, Alpha and Beta models andassumes that the optional auxiliary fuel tank is installed.

Advantages - R22 Beta II

  • Can be found in most countries in the world.
  • Excellent automatic throttle governor.
  • Good storage space in cabin under seats.
  • About 10 knots faster than the Schweizer helicopter.
  • Powerful for its size. Good high-density altitude performance.
  • Engine significantly 'down rated' for more performance and extended life.
  • Mechanically very reliable; little unscheduled maintenance, especially on 'low time' aircraft.
  • Often cheaper to buy and needs less maintenance than the Schweizer.
  • Many more Robinson dealers and service centres around the world than Schweizer has.
  • Robinsons two bladed main rotor requires less hangar space than the 3-bladed Schweizer.

Disadvantages - R22 Beta II Helicopter

  • One non standard 'T-Bar' Cyclic control. (Not necessarily 'bad', just different than other helicopters).
  • 2200 hour 'Time In Service' major overhaul / rebuild required on the R22 costing an eye watering amount.
  • FAA regulations (U.S. SFAR 73) require 20 hours minimum dual instruction before solo; 200 hours to instruct in the R22, whereas SFAR 73 does not even apply to Schweizer helicopters.
  • Many instructors who teach in both models believe the R22 is less stable and somewhat more difficult to learn in initially.
  • Smaller cabin size. 240 lbs max per seat weight capacity. Approx 335 lbs maximum cabin weight with full fuel.
  • Larger pilots often cannot fly with larger passengers due to maximum weight / fuel limitations.
  • 10 year calendar life on main and tail rotor blades. (Very expensive to replace.)
  • Tail rotor pedals are not adjustable. Taller and 'larger' pilots are often uncomfortable in the smaller R22cabin or can be too large to fly it at all.
  • Carburetor fuel system. Pilots much closely watch carburettor heat or can encounter problems with carburettor ice.
  • Because of weight and other considerations, Robinson no longer offers an R22 instrument training helicopter.

The Schweizer 300CBi Helicopter

The Schweizer 300CBi was introduced in 1995 as a primary trainer to compete with the Robinson R22. By 'down rating' the engine and running it 500 RPMs slower than the 300-C model, and by lowering the gross weight by 300 lbs., Schweizer was able to achieve longer component times on many life-limited parts, longer projected engine overhaul times, and more fuel economy, in order to make the 300CBi more cost-competitive with the Robinson R22. The 300CBI's predecessor was the H269.The advantages and disadvantages of the '300CBi' model are basically the same as those for the older '300C' model.

Advantages - Schweizer 300-CBi Helicopter

  • Mechanically very reliable.
  • Large comfortable cabin accommodating taller and larger students and instructors.
  • Superb safety record and crashworthiness with over 20 million flight hours logged.
  • Conventional cyclic control. (i.e. in-between legs) Excellent electric trim system on the cyclic.
  • More stable and easier to learn in than the R22, according to most instructors who train in both.
  • No major overhaul requirements, individual components are replaced as and when necessary.
  • Tail rotor pedals are adjustable for shorter and taller pilots.
  • 1750 lbs maximum gross weight for the Schweizer compared to 1370 lbs for the Robinson R22 Beta and Beta II series helicopters.
  • 3 bladed fully articulated rotor system is smoother and has more rotor inertia than the 2-bladed R22s.
  • Touchdown Autorotations are somewhat easier than the R22, due to more rotor inertia. Excellent for CFI training.
  • Fuel-injected engine. No requirement for carburetor heat or problems with carburetor ice. (NOT ON H269)
  • Although heavier, the Schweizer burns about the same amount of fuel per hour as the R22 Beta II.

Disadvantages - Schweizer 300-CBi Helicopter

  • Cruises about 10 knots slower than the R22 Beta II. Flies more 'nose-down' than the R22.
  • Requires more scheduled maintenance, hence more downtime for maintenance.
  • Initial acquisition costs can be 50% or more higher than for a Robinson R22 Beta II.
  • Acquisition and insurance cost are higher due to higher aircraft values than the R22 often resulting in higher training rates.
  • Very limited storage space in the cabin compared to the Robinson R22. External cargo baskets are available.
  • More expensive to operate and insure and therefore priced higher than the R22 Beta II.
  • 3-bladed Schweizer requires more hangar floor space than the 2-bladed Robinson R22 series.

The table below compares some figures for these aircraft. Amounts are approximate and may vary by model & optional equipment..... Values are based on the manufacturer's published data at the time this information was written.....
