AJ Aircraft RC Planes: Laser, Slick and Extra for 3D and Precision
AJ Aircraft is a maker of high-performance aerobatic RC planes founded by Andrew Jesky, a well-known competition and 3D pilot. Its airframes cover 3D, extreme aerobatics, precision and sport flying, with signature models including the Laser 230z, the Slick 540 and the Extra 330SX, plus the Laser Z200, Acuity, Raven, Proteus biplane, TA Horizons and pattern planes. Many models come in several sizes from about 56 inches to over 100 inches span, for electric or gas power.

What sets them apart
AJ Aircraft designs focus on light but strong airframes with large control surfaces and balanced flying characteristics, so they hover, tumble and knife-edge predictably. Competition-style planes are designed around precise tracking and neutral handling, which makes them rewarding for pilots learning advanced aerobatics. Many pilots move to these planes after learning 3D basics on foam models; techniques are covered in how to fly 3D RC airplanes.
Choosing a size
- Around 56–60 in: electric, transportable, good for club fields.
- 70–80 in: larger electric or smaller gas engines; more stable.
- 90–100 in+: giant scale gas or high-voltage electric; maximum presence and smoothness.
Larger aerobatic planes come with the practical demands of big models; see large-scale RC planes.
Setup tips
- Use the recommended servos; large control surfaces need torque and precision.
- Set CG, throws and expo as the manual suggests, then refine.
- Program flight modes for precision, sport and 3D rates.
- Balance the prop and spinner carefully.
- Check all hinges and linkages before every flying day.
Who they suit
These planes suit pilots comfortable with low-wing aerobatic flying, ideally after a foam 3D plane. Their predictable handling makes them forgiving for their class, but they’re still fast and agile. Building and setup take care, especially for larger gas versions.
Electric or gas
Electric versions are quiet, clean and quick to set up but need large high-voltage battery packs. Gas versions offer long flights and cheap fuel, but add vibration, ignition systems and maintenance. Club rules on noise may decide for you.
Before buying
- Choose size by transport, field and budget.
- Budget for servos, power system and batteries or engine.
- Check spare parts availability in your country.
- Find pilots at your club flying similar planes.
Learning 3D on a big plane
Large aerobatic planes are surprisingly good for learning 3D because they react slowly and are easy to see. Start with high-alpha passes and hovering at a safe height, using low rates and plenty of expo. Practise on a simulator first, especially torque rolls and harriers, which can end in low crashes. As confidence grows, add rolling circles and knife-edge loops. Many pilots keep a foam 3D plane for practising new tricks and fly the big plane once a manoeuvre is solid.
Servos and power
Use strong, fast digital servos on all surfaces and a reliable power supply for them. Large 3D planes put heavy loads on servos during hovering and tumbling, and weak servos lead to flutter and crashes.
