B4 in the 'new' era
 

Well after visting the Southport national last week, and the highly attended regional today, im itching to get on the sticks again ( my girlfriend was right when she said id never sell up..).

I'm going to be using my trusty B4, equipped with:
Nosram Matrix Evo
Novak 6.5R (smooth can)
KO 2123
KO 301F
TrakPower 3600 30C

Is there much I need to change to the car to make it compatible with the new brushless/lipo set up?

From when I last had a play I got as far as putting lead weight in the 'usual' pods ( antisquat pod, rear chassis pods behind esc + receiver), a lead plate under the lipo, and 30g on the servo and some rammed in to the bulkhead.

Is all this still needed? Has much developed on the magic set up of blue silver spring 35 30 weight?

I'd appreciate a full run down of a current set up if possible?
I've also heard of people trying to put the motor as close to the gear box as possible, by running a smaller spur, is still still happening? if so how? and what gearing?
I'm going to assume this is to minimise the pendulum effect?

Sorry for all the questions, Id appreciate and information put forward!

So many views.. no responce :bored:

I'm no expert but not much appears to have changed!
I don't think the setups changed much from Ben's in this topic at the beginning of the season.

I don't think the setups have changed too much, some folk run silver springs on the front and many run the Ghea pistons.

The super-short wheelbase mod that I hear was common a few years ago seems to have fallen out of favour.

I believe the smaller spur is as you suggest, to reduce the pendulum effect caused by the motor hanging out of the back.

HTH :)

Thank you for the help, i thought there would of been more progress since the lip move, suppose you don't need to that much!
Again, thank you!

Only advice I can give, is with that 6.5 in their, then get some weight in it.

Rudebits do some nice brass weights (for the poser in you), or you could run the GHEA or Trishbits bulkheads.

Paul, it's all pretty standard stuff track to track.

Run a 75 tooth spur when it's dry. Put it back to a 78/81 when it's wet.
I think ive got a speed passion 7.5 geared 23/75 at the moment.

Recentley been trying 50g brass tray under the lipo, 34g brass plate under the servo.

Ben is that in addition to the ghea front and rear bulkheads or instead of?

Correct me if I'm wrong (and I'm sure plenty people will :lol: ) the Lipo effect seems to have only affected touring cars, or cars where the battery has normally only been on one side, so needing to re-jig the weight distribution.

Yes, you are wrong!

It has made a notable difference in off-road, which is why there are so many weight kits around to bring the LiPo cars up to NiMH weights (although the latest LiPos are getting quite heavy now).

For those that choose to run without extra ballast, the basic weight distribution of the cars is affected. On a B4, the lighter battery actually moves the centre of gravity further back (contrary to what you might expect!).

I genually appreciate the advice here! Last time I gave it a go I simply chucked some lipos in and went at it..

I knew there would be some subtle changes, which I have added!

weight added -
10g under steering rack
10g in front of servo
10g inside the front bulkhead
20g top of servo ( may raise COG though..)
x2 10g in rear pods behind electrics
15g behind anti squat brace

I'd not need to add as much in the various areas if I opted for brass items, but trying to keep it cheap i've opted for the above.

I also have a lead plate to try to go under the lipo.
I just need to follow up with the spur and its pretty much ready to go..

for now, here she is!

Nice photo Paul, how'd you do that?!

Thank you :) taken straight from the camera, no effects in Photoshop! Just fiddled with the White balance and shutter speed.

stainless bulkheads
 

Hi paul, i've put stainless front and raer bulkheads in my b4 i got them off noel alias CREAM on oople they are shit hot mate and they fit like a glove well worth asking him weather he has any left:thumbsup:

Hey,
Can u make pic of where u putted lead etc?
Thanks

In addition to

Sorry for this very newbie kind of question but......

I assume the adding of weight is purely for balance/traction reasons and not to do with a weight limit? had a quick look through the brca handbook and cant see any mention of weight limits. Again sorry for this very basic question but im moving into off road from the dark side (tc). Just sorting my B4 for my first run this sunday and adding the weight now but dont want to add too much before i can get a 'feel' for the balance on track first.

it's not to do with the meeting the 2wd weight limit, rather to improve handling by altering balance in corners, over jumps and through bumps.

heavy seems to be the order of the day.

Cheers:)

Sorry for the delay, took a picture today, hope it helps!
