Tips, tricks and optimizations

Flight optimizations:

  • Priority adjustment: Experiment with the focus on different flight styles. A slightly head-loaded setting increases stability, while a cock-loaded position improves agility.
  • Dual rate settings: Use your transmitter's dual rate function to program different sizes – smaller for precise flights, larger for art flight.
  • Expo settings: 25-30% Expo on transversal and vertical rudder improves the precision around neutral position without reducing the maximum deflections.

Performance optimization:

  • Rechargeable light: 4S batteries with 3200-4000mAh and high C rate (30C+) are recommended for maximum performance.
  • Propeller alternatives: A 12x8 2-sheet propeller can provide more thrust, while an 11x8,5 3-sheet propeller offers a good compromise between thrust and scale optics.
  • Cooling improvement: Enlarge the air inlets easily if needed to improve the cooling of the engine and regulator at high outside temperatures.

Structural improvements:

  • Suspension reinforcement: In the case of frequent start-ups of uneven surfaces, an additional amplification of the suspension mount can be useful.
  • Secure servo connections: Secure the servo plugs at the receiver with a drop of silicone adhesive or special plug fuses against vibrations.
  • Floating mount: Pay attention to the exact alignment of the floats – a light V shape increases the stability on the water.

Frequent questions and solutions

Problem area: electronics and binding

Question: My Turbo Timber does not react to the transmitter after binding. What can I do?
Solution: First check the binding procedure according to instructions. Make sure that the receiver and the transmitter work on the same protocol (DSMX/DSM2). Also check the servo plugs at the receiver for correct seat and correct polarity.

Question: The LED lighting does not work. How do I fix the problem?
Solution: Check the connection between the LED controller and the receiver. Usually a loose plug or a defective connection is the cause. Also check the configuration of your transmitter – the LED control is often assigned to a specific channel.

Problem area: Flight properties

Question: My Turbo Timber tends to tilt when starting water. What's that about?
Solution: The most common causes are incorrectly aligned floats or unequal weight distribution. Make sure that both floats are mounted equally high and the focus is correct. Even too high speed when running water can lead to tilting – start with moderate engine power and increase it only when the model runs stable.

Question: The model is difficult to control and reacts oversensitively. What can I do?
Solution: First check if SAFE Select is activated – for beginners, flying can be difficult without this support. Reduce the outputs via Dual Council and increase the Expo values. Also check the focus that ensures more stability in a head-loaded model.

Problem area: Mechanical problems

Question: The support surfaces are shaking despite firm screwing. How can I fix that?
Solution: Check the bearing surfaces between hull and supporting surface for damage or wear. A thin piece of foam or moss rubber between the contact surfaces can eliminate play. Make sure that the screws are not overturned because this can damage the thread.

Question: After a hard landing, the motor runs unround or vibrates strongly. What's to do?
Solution: Demonstrate the propeller and the spider and check the motor shaft for bending. A damaged propeller can also cause strong vibrations. Also check the engine mount on loose screws or cracks in the engine mount.
