Introduction

In order to minimize the impact of the absence of the English version of the Regulations this document contains relevant information to support the design.

2.
2.1

General Rules Changes
Radio Control

PCM radio is mandatory. 2.4GHz radio is allowed as an alternative.

2.2

Voltwatch

For all classes the use of a commercial voltwatchis mandatory.

2.3

Flight Video

Maximum score of 10 points in 2010 instead of 5 points in 2009.

2.4

Qualifications Flight

Regular Class minimum Payload: 4kg Open Class minimum Payload: 10kg

2.5

Report

Total Score: 220 points New technology to be evaluated Electrical Design: 20 points.

Maximum page allowed: Micro Class: 35; Regular Class: 37; Open Class: 45. One of theplans of Regular Class may be in A2 format. (ONLY ONE, to be chosen by the team)

3.1

Regular Class Major Rules Modifications
Cargo Compartment (Payload Bay)

The aircraft must have only onecompartment for positioning the cargo (or payload). The compartment should have parallelepiped geometry, and can have its dimensions at the team choice, but neither side of this parallelepiped may exceed 500mm.

3.2

Dimensional Restriction

Sum of dimension shall be within 4.0 and 6.5 meters. (For reference see Section 2.2 of 2009 Regulations)

3.3

Dimensional Precision

Airplane withsum of dimension inside the allowed range (4 to 6.5 meter): Maximum allowed error without penalty: ± 0.60% of the sum specified in the report. Error in excess of ± 0.60%: 2 point penalty for each 0.1% exceeding the maximum allowed error. (Example: 0.764% error in 3.27 point penalty) Airplane with sum of dimension lower than 4 meter: 2 points for each 0.1% error. (Example: 0.95% error Airplane withsum of dimension greater than 6.5 meter: 2.5 points for each 0.1% error. (Example: 0.692% error 17.31 points penalty) 19 points penalty) 0.164% exceeding, resulting

3.4

Payload score modified

1 point for each 0.1 kg of payload for both takeoff sectors.

3.5

Other Changes

Accuracy Equation changed Structural Efficiency score modified FPV factor inserted in Regular Class (see Section 7.10.3 above) Distance for landing Bonus point changed to 61 meters (2009 Score for Minimum Volume Box changed. 122 meter)

Translation of some specific 2010 Regulations Section

Section 6.7 -Sending Documents in electronic format
Some documents in special may be sent via email, CD, DVD or any other way to the technical committee. These documents shall comply with the following rules: - Mandatory file format for text, plans, drawings etc.: PDF - Accepted file format for figures; JPG - Accepted file format for videos: WMV - Maximum email size: 5Mb.

Section 7.10.3 - Empty WeightPrediction
Aiming to encourage teams to improve their engineering processes and as well as build and thoroughly test their aircraft as early as possible, a factor called Empty Weight Prediction Factor (FPV) was inserted. This factor is calculated using the following formula, with weight in kilograms (kg):
FPV = 1.10 - 15 x abs[ (Predicted Weight - Actual Weight) / Predicted Weight ]
