About the Grob G 115
Aircraft overview
The Grob G 115 is a two-seat, low-wing training and aerobatic aircraft built by Grob Aircraft in Germany. It first flew in 1985 and entered production in the late 1980s, with several civil and military variants following. The type is known for its glass-fibre reinforced composite airframe, side-by-side seating and use in ab initio, instrument and aerobatic training. It matters in the used market because it combines a purpose-built trainer layout with certified aerobatic capability, rather than being a touring aircraft adapted for training work.
Performance & specifications
Performance depends on variant and engine installation. The widely used Grob G 115E is powered by a Lycoming AEIO-360 flat-four engine rated at 180 hp, driving a constant-speed propeller and supporting inverted flight systems for aerobatics. Typical cruise speed is around 120 to 125 knots, with published range figures commonly in the 500 to 600 nautical mile class when operated in a training configuration. Service ceiling is about 10,000 feet. Useful load varies by equipment fit, but buyers should pay close attention to actual empty weight, since military avionics, radios and aerobatic equipment can materially affect payload.
Cabin & avionics
The Grob G 115 seats two occupants side by side under a large canopy, giving good visibility for instruction, formation work and aerobatic training. The cockpit is functional rather than spacious, with dual controls and a layout intended for student and instructor use. Avionics vary widely. Many aircraft retain conventional analogue flight instruments with VHF radio, transponder and basic navigation equipment. Upgraded examples may have Garmin GNS 430 or GTN series navigators, modern audio panels, Mode S transponders, 8.33 kHz radios and engine monitoring. The Grob G 115 was not delivered with Garmin Perspective, and G1000 installations are not typical for the type.
Buying & value
Used Grob G 115 aircraft appeal to buyers seeking a durable certified trainer with aerobatic credentials. Important pre-purchase items include composite structure condition, canopy condition, landing gear wear, evidence of hard training use, aerobatic history, logbook continuity and compliance with Grob service bulletins and airworthiness directives. Engine and propeller times are especially relevant on G 115E aircraft, as the 180 hp aerobatic powerplant and constant-speed propeller have higher overhaul cost exposure than simpler trainers.
Common variants include earlier civil G 115 models and the more powerful G 115E, widely associated with military training fleets. Market positioning is usually above basic two-seat trainers such as older Cessna 150 or Piper Tomahawk examples, but below newer glass-cockpit training aircraft. Value is driven by variant, remaining life, avionics, maintenance history and whether the aircraft has been operated privately or in intensive flight school service.
