Proposals for TC Meeting at the WC in Kromolice

My dear friends,

In this post I have collected all the proposals you have sent. Some of them are contradicting to each other, so read carefully, discuss with your teammates and try to come to the TC with clear ansver of yes, or no. At the committee meeting we will rather vote. There will be no time to discuss such amount of proposals on site.  

One remark in advance from my side: The freeing up the connectors I would allow with the following restrictions:
– The connectors must make the reverse conneting impossible. Neither by means of polarity, nor by current flow. I.e. ESC and Battery side can not be overchanged.
– The connectors must be set the way, the limiter measures the highest voltage only of the battery pack. I.e. measuring with pin inserted into the ballancer port is not allowed.

Looking forward to see you at the Worlds!

Csaba Dánielfy
M Section Leader

Here you will find the proposals arrived.

Dear friends

Belgian proposal

1.      Start procedure oval :

The start procedure was changed from 10 sec to 6 sec as a main reason to have less accidents at the start line.
Now everybody starts full throttle and on an official parcours is not able to reach the starting line within the 6 sec.
The result is that at the first boy, there are more crashes than before.
So our proposition is to change back to the 10 sec rule.
If the rules are followed and enforced when necessary, this is the best solution in our opinion.

2.     

Best regards and hope to see you all soon

M section

Hello, I send you the proposals from Bulgaria.

Proposal 1: Free the connectors rule for big limiters like in mini classes. Every competitor use connectors by their own but must provide adapter to 5.5mm and 6.0mm like in the existing rule. Reason: The 5.5 and 6.0 connectors are week, they need to be exchanged every season. Most of 6.0mm are week and get loose in just a few races, there are planty of options for more reliable connectors. Proposal 2: Free the type of Litium batteries used, LiPo, LiFePo, LiIo, LiHV, but keep the rule for minimum weight and energy limit. Proposal3: Raise the Voltage Limit in all M-classes to 43V

Thank you, Best regards,
Todor Stoyanov

Polish proposals for changes to the NAVIGA Section M Rules 2026

1.
We propose that batteries be weighed before racing during technical inspection, and then
marked with a seal/sticker that must remain visible on the battery installed in the model
without removing it.
Battery weighing today is fundamentally different from the old “weight battery” regulations
— the battery must meet a minimum weight, not a maximum one. Therefore, there is no
risk of increasing the battery weight after a race, for example due to water entering the
model.
Removing batteries before every heat often creates difficult situations, including dangerous
ones such as short circuits, which could be avoided with this solution.
At the request of the judge, an additional battery weighing may be carried out after a race,
and it shall be mandatory for the top 3 competitors in the final.

2.
We request that, in the event of a model failure on the water, only the hull be considered the
model carrying the license number and racing number, similarly to the rules concerning the
placement of model registration (license number), which cannot be placed on a float or
hatch cover.

This concerns hydro classes in particular.

The purpose is to establish that the model consists of one part, not three or more. If floats or
other parts separate from the hull during a race, under the current rules another competitor
may not touch any part of the damaged model, even if it is broken into three or more pieces
and these pieces are located in different areas of the course.
This creates many situations in which other competitors are disadvantaged because they
are forced to avoid multiple parts of a damaged model, and this may lead to unfair
disqualification of a competitor.

3.
We propose removing limits on the number of battery cells in all classes.
We believe that the use of limiters and a specified energy limit is already a sufficient factor
distinguishing the different classes.
Specifying the number of cells is a relic from the times when energy was limited by battery
weight.
The only limitation should be a maximum voltage of 43V.

4.
We propose removing from the regulations the possibility of using NiMH and LiFePO
batteries.
For several years nobody has been using these battery types, so this rule has become
obsolete.

5.
We propose that, in parallel with the points system, results in F3 classes also be shown in
seconds.
For each penalty point, 5 seconds are added to the result.
Example:
If a competitor completes the course in 20 seconds with no penalty points, the result would
be: 146.000 points / 20s
If a competitor completes the course in 20 seconds and receives 2 penalty points, the result
would be: 144.000 points / 30s
The purpose of introducing parallel time scoring is to make F3 results easier to understand,
as the current scoring system is unclear to many competitors and reduces interest in this
excellent class.

6.
We propose changing the buoy regulations for Eco classes.
Currently, the buoys for Eco classes are regulated together with the buoys for F1 and F3
classes (the regulations require them to protrude 10 cm to 20 cm above the water surface).
A buoy protruding only 10 cm in an Eco race does not fulfill its purpose. In addition, such a
small buoy can easily be damaged, which may lead to a race being repeated.
We propose separating the Eco buoy regulations from the F1 and F3 regulations, and
changing the protrusion height of Eco buoys to 20 cm to 30 cm above the water surface.

7.
We propose introducing the possibility of measuring times in F1 and F3 classes using a
dedicated timing device connected to the results presentation system, instead of using the
current three-stopwatch timing system, provided that it is not an AMB/MyLaps device.
Such a device would require approval from the NAVIGA Section M Committee, led by the
Section M Leader.

Proposal of Italy

Dear Chef of the Commission Section M,

I am following up on the emails previously exchanged between FIM and Naviga, and I would like to bring the following proposals to your attention:

1. Rewriting and Revising the Regulation: It is essential to make the text more modern and clear, especially to facilitate understanding for new individuals, not just for those who currently follow it out of inertia. The current regulation is outdated and scattered. I have already shared a draft with you that we can work on.
2. Integration on the Use of Batteries and Limiters: I propose the inclusion of specific guidelines regarding the use of batteries and limiters for the various categories, in order to improve the management of international and national races.
3. Regulation of the Issuance of Clearance: I suggest revising the procedures for issuing clearance for pilots requesting to participate with another nation. In addition to the general conditions already present in the regulation, limited and well-motivated cases should be included to facilitate this operation, avoiding approximate evaluations.

I remain available for any further clarifications and insights. We are in discussion with the one organizer here in Italy for try to organization the WC 2027.

Best regards,

Alessandro Cremona
