FAI 2014 meeting results

In case anyone is interested here is a summery of what was done in regards to the F5 events at the meeting in Switzerland last week. In a nut shell F5 is taking the path to allow use of telemetry as well as stability systems unless otherwise indicated in the category. Most other FAI events are heading in the opposite direction with actions taken at this meeting to restrict the use of telemetry and stability systems. The argument that allowing use of these systems is "not pure" seems to be the prevailing argument against their use by opponents. What they fail to see is that by not adopting the current technology they risk becoming a "antique" event.

Steve Neu

This Year) for all F5-Classes:

5.5.1.3 General Characteristics of RC Electric Powered Model Aircraft F5
d) Any transmission of information from the model aircraft to the pilot is prohibited with the exception of signal strength and voltage of the receiver battery.


New 1.01.2015:
d) Any kind of electronic systems is allowed. Exceptions are written in the special rules of these classes.

- Allow augmented stability systems

- Allow systems that limit energy used during climbs

- Autonomous or preprogrammed flight is not permitted

- No GPS or similar positioning systems waypoint navigation is allowed



5.5.1.4 Energy Limiter (F5B/D/F)

The energy limiter/logger is located in the electric circuit between the battery and the motor. In the case of a limiter, the interruption must either persist permanently or for a defined period of time. Instead of an energy limiter, the contest organiser may supply a “real time radio telemetry logger” that transmits logged data to the ground. The energy data and motor-run data shall be made available to the pilots.


Rule for F5J:
d) A Spread Spectrum technology receiver that transmits information back to the competitor-operated transmitter, is not considered to be a “device for the transmission of information from the model aircraft to the competitor”, provided that the only information that is transmitted, is for the safe operation of the model aircraft, ie. signal strength and voltage of the receiver battery.
No changes in this matter are planed.

The first FAI World Cup in F5J will run this year! Thanks to all organizing clubs.

Thanks for the report Steve.

Guess this doesn't affect F5D much (my primary interest at this time). I was wondering if any of the on-board telemetry for a limiter used in F5B will ever trickle down to F5D.

I know what you mean about antiquating events by not adopting new technology. From what I read in magazines, the same argument persists in the highest level of motorcycle road racing in the FIM (Moto GP) where some argue traction control, active suspension, electronic clutchless shift, etc. shouldn't be adopted. The other option is to let the world pass you by.

So varios and real time data of height, energy used etc will be allowed in F5B as from 2015?

Wow, that s gonna change the game! Some inheritantly unstable , but very slippery, airframes could be flyable with stabilization systems. Its going to be interesting seeing what airframes come out of this.... Here's looking at you Dave!

Next time allow automated programs to fly the planes. This is not "advancing" this is making things easier. Now everyone will have to cramp another electronic deivce into his plane. Sad...

I do not care about the telemetry data. But now we have to use this weird additional limiter is nonsense.

No--automated flight controls with GPS or similar are not allowed and will not in the foreseeable future.

Stability systems for planes provide similar enhancements that model helicopters enjoy with their heading hold gyros and flybar-less systems. New radios are already starting to come equipped with the 3 axis stability electronics built in. You can't stop the progress.

Yes but actually the airframe flys well it is the launch and landing that is strange...

I think if it becomes a game of who has the best on board electronics it is time for me to quit, may be getting to old for this stuff and starting to sound like my dad but this tech stuff is beyond a guy that is just good at working with his hands... I think I need to re-think my hobby...

Don't other classes allow the same telemetry, RSSI and battery voltage, already?

What is different in these new F5 rules in this regard?


Thanks,

Pat MacKenzie

I think it'll allow for some crazy flying machines to be created that otherwise wouldnt be flyable.

Stuff like the eagletree gaurdian arent hard to setup, not much more tricky than simply plugging in and binding an Rx.

Even simply stuff like pushing CG's far aft will be an option.

Dunno If I think its a good idea or not, but its certainly going to change the game and allow for some seriously innovative stuff

So this would allow the use of gps from the model to tell the pilot when to turn.

This with a 3d gyro would certainly result in quicker times.

So in order to be competitive now, you will need a telemetry enabled radio with 3d gyro. I think you have just made the class less popular and more expensive and reduced the skill level. There is a reason why technology should be limited

Who was at the meeting and who voted for this?

Darron, The way I read it GPS will not be allowed but all other stuff will. I don't know how that will affect F5D other than having live info on energy used but for F5B over half of the flight has just got easier.

I too would like to know who has pushed for these new rules, seems to me the competitors were never asked about possible rule changes.
