Regarding the driver with the 1800 gram 733, he is driving club races and the stock class, I don't think the minimum weight will be lowered in those classes anytime soon. I've seen other 733's around the 1700 mark without any big changes to save weight.

I hope we can have a clear split in classes some day like the electric guys, a stock class fully aimed at equality and cost savings and a pro or mod class in which all the latest stuff is used and cars can be used to their full ability.
I feel your pain DS; but I'm with Roelof on this one. If you think it's pain to add 200 grams... try losing 200 grams. The weight rules should cover the majority of all cars on the market not just one. I think SPOCK from Star Trek once said. "The needs of the many out weight needs of the one."
I'm against two classes in nitro sedan. People say there are too many classes in electric as it stands now. And if you show up to race with not enough people in your class or in my class that sucks.
When you change classes in Electric your really only talking about a motor and Speedo and body type. When you do this in nitro( the way you explained it) this could mean a ton of Hop-ups or a class filled with all the same make and model cars and thats no fun.


Pass you soon...

There is a friendly discussion going on between Franky Noens and various manufacturer to find a compromise for the weight for the next AGM voting. Most manufacturers want to set the weight at 1650g which Franky supports so far.

On the other hand we havn't received any confirmation what happens to the other technical rules (tyre additive, 1/8 rules, ect.). I hope EFRA releases some more information on this matter soon.

i am all illuminated, thank you for clearing this out.

I've been trying to save weight in my 733 for over 1 year now and i can;t get the car past 1765!!!!!!!!!!!!!!!!!!

And i mean light weight servos titanium screws on top and in the chassis light weight body light weight everything i can think of!!!!!

To get the 733 down to 1550 is never going to happen if Australia adopt this rule i wont be able to compete at that weight.

Make the rules equal not just for the 1 or 2 cars that can just get to that weight

Couldn't agree more Aaron. Jay at Walter Hobbies is selling Serpents for a ridicilous low price, and I know of a few new drivers in Brisbane that have taken the opportunity to get a brand new car cheaply because of the good price. Surely that can only help the sport. Rules that only favour my camp and Mugen cannot be good for the sport.

It looks like this matter is going the right way now however; manufacturers need to have their input into this. The outcome can only be for the better if they can work the limits out for themselves together, and submit their decisions to EFRA and IFMAR. Development of better cars will still move ahead, since they all want to be the best.

While in on the subject; it's wrong for IFMAR and EFRA or any other regional block to have dramatically different rules. Only small variations to rules should be tolerated. Each block needs to have a right to determine their own rules, but dramatic changes like this should really only be introduced after at least some consultation with IFMAR (the IFMAR blocks). I hope the AARCMCC and FEMCA will be against a change to this weight with IFMAR.

Kindest regards,
Lars.

That makes all brands to design new cars for next year. And the drivers to switch cars for new season.

this is sad news for 2012 racing, and people looking to return to racing this year just may think twice. 2012 is looking like a lets sit back and wait and see what happens. not good for Clubs looking for new members, or even keep some of the ones they have now.

I can not imagine people will stay away if the weight remains 1700 gram. For sure new drivers do not care such a heavy car, I even think those guys must be happy that their car does not need huge investments to get it.

well some people are looking at purchases to attend Nationals late in the year, with this news, all i see is buy a car that will be needing to replace with in months. that is certainly not advantageous to be doing in this current climate. that is fine with people that have cars already and it isnt really effecting them much at all, but by the end of the year their cars may need to be renewed anyhow. but i will not make purchase a car for one event to be outdated as it crosses the finnish line.

Default weight limit a problem?

The EFRA with its members voted on a new weight limit of 1550 gr. in the meeting. Several people complained about it, So lets look at it closely

My NT1 2009 oldy with a few hopups

with a life 700mah battery weighs
New Efra rules-2012-01-12-20.56.50.jpg

with the car
New Efra rules-2012-01-12-20.57.56.jpg

and with a heavy body
New Efra rules-2012-01-12-20.58.11.jpg

what have a used with lightweight parts;
ti screws on top
ti trannyshoes holder
light axle front and gearbox
cap plastic gear in the diffs
cap spurs
alu pillowballs
plastic pillowballnuts
life 700mah (6 dollars)

what can be done; and going to because its the hobby and it can be done
lose the batt switch (maybe not)
lose the transponder holder (maybe not)
shorten the servo wires (yes)
thinner tank tyrap
lose the griphandle
get the ti axle for the arms from cap
ti wheel nuts from exceed
lose the receiver box (not for me though)
get the small spectrum receiver (much lighter )
tranny spur holder lightweight
brakedischolder lightweight
hydinamic clutch

anyone more idea`s

Still need to test the life 700mha. it has to last a final naturally
otherwise i have to get an other one and the weight will be higher

I like it, its fun getting the car lighter and seaking for ways to do it without losing strenght and cg. i hate bolting weight to the car, it goes against my racer attitude and feel of the mechanics and roadhandling.

All it needs is little less paint on it or a lightweight body. and i will be there i think.

Look up the prices and you know the cost.
No new car is needed, all parts are there to get very near and everyone can do it easily.

Capricorn does it easily
Mugen can do it i heard
Serpent , well i have seen mazzeo`s car does it also so the parts can be marketed i think and will be this year i suppose

So lets lose weight people and be faster then the 1/8 class yeah bring it on.

Start put some wheels on whit some foam on. I dont hope you would start a race on these. Then the weight will show a different number.

I'm on the side of the knockers; but in all fairness the minimum weight should be measured with very little foam on the tires, be safe from disqualification. Cars are weighed after a race, and you could come in with nearly no foam left after a long final.

Kindest regards,
Lars.

The above lol how much do you think people are going to spend i spend $60 on titanium screws how much more will i have to spend on the serpent to get it down to that weight if Australia follows suit.
Bringing the weight down is just making this sport more expensive.
Fair enough people have to but the car buy the engine starter box parts tools truer and the rest...............

Now they have to go but every light weight part they can find im starting to modify my own parts lucky i have a lathe and a mini mill so il lightening shit myself.

But forget that i hope the Brands make there cars lighter and get them into the market by the end of this year.

But all EFRA has done is if making the serious racer spend more money to lighten there car my opinion this is stupid but can somebody give me some points why EFRA would want to lighten the weight limit.

I Don't want to hear the less weight my engine will make 5min or this will save tyre wear what is the real reason for the rule change???????????????
Please

Nice work JW, you're already very close.
The 700Mah life will last a 30min final, Bart has been using one this season.

Some more things to try:

-Plastic shock bodies of you're not using them already. Besides being lighter the plastic ones are also better (or less worse might be better wording)
-Aluminium clutch bell
-Lightweight body gives around a 15 gram difference, at the euros we even had some 0,4mm (or something like that) thick bodies from Blitz. They did improve the lap time.
-Titanium wheel axles
-Aluminium driveshafts

And loose the receiver box.

I always try to end with tires which have around 0,5-1mm of foam left on the rim. Start monitoring the wear during qualifiers and calculate the tire size you're going to start the final with. Once you get more experienced with this you can take more risks. And sometimes you will only have plastic left for the last couple of laps if you took a bit too much risk.
