ELECTRO-ACROBAT RETRO-MODELL: A legendary kit that will rewrite your model-making history!
Discover the secrets of the world champion – now in your hands!
Imagine holding in your hands the exact same model with which Rudolf Frudentaler conquered the world throne in the F5B electric category four times (1986, 1988, 1990, 1992). It's not a dream - it's a reality that you can order right now!
The Elektro-Akrobat Retro-Model is not just a kit. It is a piece of model-making history, a legend wrapped in original retro packaging, a bridge between the golden era and the present. And most importantly of all – it is your key to perfect flying.
Why Elektro-Akrobat? Because the results speak for themselves!
Designed by a master for masters.
Rudolf Frudentaler was not just an ordinary designer. He was a visionary, a perfectionist and, above all, a four-time world champion. When he designed the Elektro-Akrobat, he wasn't just creating a model - he was creating a winning formula.
Every line, every angle, every detail has been calculated with mathematical precision and tested in the toughest competition conditions. The result? A model that never disappoints.
The Elektro-Akrobat was originally designed for the F3E aerobatic competition category – that means the highest possible level of technical demands and performance. But here's the best part: thanks to its excellent flight characteristics, it is also perfect for recreational pilots!
This means you get:
Competitive performance without competitive stress
Professional flight characteristics with recreational fun
Masterfully tuned aerodynamics for everyday flying
An authentic retro version – like time travel!
Original packaging + retro parts = an indescribable experience
This kit is not just a copy - it's an authentic retro version including:
The original packaging in a design from the golden era of the 80s and 90s!
Genuine retro parts made to original specifications
A nostalgic atmosphere that will transport you to the times when model making was pure art
Breathtaking technical specifications
Span: 1700mm - Ideal size for both stability and maneuverability
Length: 1300mm - Perfect proportions for all acrobatic maneuvers
Area: 38dm2 - Optimal wing loading = easy control
Weight: 1500g - Lightweight but stable - the ideal compromise
Motor: 650W - Enough power for any maneuver
Battery: Li-Pol 2200-2600/6S - Long flight + high performance
Why are these specifications so important?
The 1700mm span is not a coincidence. It is a mathematically calculated value that ensures:
Perfect stability when flying slowly
Exceptional maneuverability during acrobatics
Optimal balance between control and performance
A weight of 1500g means that the model is:
Light enough for sensitive control
Heavy enough for stability in wind
Perfectly balanced for all types of maneuvers
The 650W motor provides:
Vertical climb without loss of speed
Endless possibilities of acrobatic figures
Power reserve for the most demanding situations
