The clutch pedal is too heavy to hold out for any length of time. Gear lever is too heavy in operation, particularly when using 2nd. gear. Brakes are poor, insufficient braking for high speed work, and too much pedal pressure is required. Propellor shaft squeaks for 4 or 5 minutes after starting from cold, but goes off when warmed up.
