STACK DA 50€ ! 💰💸 AXIS Argus ECO è quello giusto?

Hobby Insights: Addressing Cost Challenges in the Hobby Community

Introduction to Current Challenges

• The speaker discusses the importance of addressing key issues to better promote their hobby, highlighting that one major problem is pricing.

Price Trends Over Time

• Two years ago, building analog setups cost around €100-120, but current prices have skyrocketed, making it feel almost impossible to assemble a similar setup today.

Focus on Economic Stacks

• The speaker introduces a specific stack from Accessis as an example and mentions testing another stack over recent months. They aim to explore characteristics and compromises for budget-friendly options.

Affordable Options and Discounts

• The Accessis stack costs $59 at full price; with a discount code provided in the description, it can be purchased for approximately €51-52. This pricing opens doors for more economical builds.

Breakdown of Build Costs

• A rough calculation shows that combining the stack with motors (€15 each), VTX camera, and an inexpensive frame can keep total build costs under €200—an impressive feat compared to past prices.

Understanding Stack Components

Overview of Stack Features

• Key components include an FC (Flight Controller) with F405 chip and integrated features like black box functionality in the HGLRC version.

Connectivity Options

• Various connectors are available for easy assembly without soldering; however, the speaker prefers soldering for reliability.

ESC Specifications

• The ESC features large pads suitable for connections; differences between models are noted but both exceed 40 amps—adequate for freestyle builds.

Performance Insights and Recommendations

Personal Experience with Stacks

• The speaker shares positive experiences with the Axis stack's performance but finds it challenging to recommend certain components due to price parity with alternatives.

Comparison of ESC Models

• Both stacks feature ESC models capable of handling high currents (55A peak), essential for optimal performance in freestyle applications.

Analysis of Gyro Performance in Racing vs. Freestyle

Comparison of Gyros

• The speaker notes that the gyro performs well at the FC level, particularly emphasizing its effectiveness in racing compared to freestyle.

• The ICM gyro is highlighted as the best option available, being clean and reliable with fewer issues than others like the BMI270.

Technical Specifications

• The ICM gyro operates at 8 kHz when paired with an F405 flight controller (FC), but this combination may lead to compromises in performance.

• Recent Betaflight versions require careful selection of FC specifications; using DShot600 and 8 kHz can overwhelm an F405, leading to operational problems.

Recommendations for Optimal Settings

• It is suggested to lower settings to 4 kHz and use DShot300 for better stability, especially since higher frequencies may not yield significant benefits in freestyle flying.

• The speaker mentions a bug associated with the ICM gyro that causes loss of control upon impact with obstacles, which is more critical in racing scenarios.

Practical Implications for Flying Styles

• In freestyle flying, crashes often result in disarming the quadcopter; however, maintaining control during races is crucial due to competitive dynamics.

• Despite some concerns about flyaway incidents, no severe defects have been observed with the ICM gyro under normal conditions.

Product Recommendations and Alternatives

• Both discussed stacks are recommended for testing; users should choose between proven reliability or potentially superior specifications based on their needs.

• Future discussions will include alternative stacks that offer different features suitable for specific builds while maintaining competitive pricing.
