Default BRCA Go Open Lipo @ 1350g for Mod

After today's BRCA AGM the Mod drivers have voted in an end to the 'round' cells for good and 'Open' Lipo for the Mod class. Must say I didn't see that coming
So any motor goes for Mod which is going to make for some interesting meetings.

Both Pro-Stock (10.5) and Mod will now run to 1350g, which is good as I can at last get rid of most of the bloody lead and brass on my car.

I thought most of the world was going to 1425 including timing?

1350 seems like going back to days of needing lightweight parts to be near weight. Seems like a big step back to me

Ill get it right at a lower weight with more black groove experience..but 1350??? wow.

Rule of 1350g min weight --> money spent on lightweight parts

Sounds like you need some roll center learnin'.

But yea, 1350 is a little extreme.

1350g is what EFRA seems to be going to and apparently IFMAR too...

my car came in yesterday at 1358 with a regular weight shell so I'm not too worried.

This is a big step forward for mod

Peeps have manged to come in below 1350 and still be balanced left to right.
You shouldn't need any special parts to get that low anyway, maybe just some creativity with regard to placing electronics, flipping belts etc.

Will be interesting to see how the lower weight effects setups with regard to springs and damping.

I uderstand why Mod didn'y want a motor limit, pushing things to the exteme and probably blowing motors, but now there's a danger of the inexperienced stuffing 3.5's in making things very dangerous.

I used titanium screws, 2.4mhz kopropo receiver, kopropo low profile servo, xray lipo tray/weights and to make my T2009 balanced I was 1400 (body 100-110gr)

Don't have any issue but out of curiosity how did you manage to be 1358?

Xray weights are 60g on their own.

wow, pretty crazy stuff...

Still, I guess lipo does make the car lighter, hence the new lower weight limit

This could make weight placement more critical, as well as roll centre/car setup.

All that speed and no grip/weight on the front or rear is going to be a testing experience....

Exclamation

Amend Rule – 6.7
6.7 The minimum weight, including personal transponders but not handout
transponders: 4WD 6-cell/LiPo = 1350g, 4WD 5-cell = 1425g, 4WD 4-cell =
1350g, Front wheel drive/2WD = 1400g.
Thinking behind proposal
Adding 150-200 Grams of Lead weight is not good and relatively expensive.
No special lightweight parts will be needed to hit this weight limit.
1 NiMH cell weighs 69-72 grams.

What a joke...

I just ripped all the weights off my car and its 1390g, to get it balanced left to right its 1418g.

"Adding 150-200 Grams of Lead weight is not good and relatively expensive.

Ill tell you whats more expensive - low profile servo, titatnium screws and ball joints to get nearer to 1350g...

Rediculous.
