hell go extreme go 2-3mm

with a robinson pinion the silent spur gear is LOUD. it is a brand new setup on both, mesh is perfect lol. Kinda sounds cool though

I use the Ae spur gear & never had
one that was not straight & true ....

okay guys, do any of u think a non-timing esc(lrp sxx comp)original version with a 17.5 revtech trinity motor(geared low on the fdr of course compared to the d3 using dynamic timing) could keep up with say a boosted esc such as a stock spec sxx or a tekin rs using a trinity d3 17.5? i only ask this cause looking at the specs of the revtech, i find out that it has a higher than usual kv rating of 3000(compared to most other 17.5's that are around 2200kv and i here are better suited for dynamic timing than the revtech). so do u think i could be competive with the lrp/ revtech combo over the guys who run boosted? the track is 140-70 and is quite fast! dont need much bottom end punch to make any of the jumps! any help would be awesome, i just need help making up my mindon what to buy!

No way they will have such a greater high speed than you and get there a lot faster. If you are racing against ESC timing you need ESC timing at an event as big as the JC race. Sure you will beat some people but you will not be on pace with the top guys unless your totally sand bagging in the stock class you might have a chance at a top 5. I think your questions might be better suited elsewhere than the B4 thread. Just .02.

Hi,

Got my first buggy, a B4.1 FT, built.

* LRP SXX TC spec V2
* LRP X12 13.5 T motor
* XP DS1015 servo (which over here says it's from Thunder Tiger, and when you open the box up says it's from Ace RC. )
* Sanwa/Airtronics MX-3X / RX451.


Feels very nice and responsive.

Quick question: what's going to break first, when I crash?

Depends on how you crash. I just broke a wing mount two weeks ago. Probably never break another one. I broke a caster block last week landing badly off a jump. I saw another guy snap the top off a shock tower crashing the same way. The front arms seem like they might be an obvious target but I have actually never broken one.

Gotta love the Mudvayne...

Hey guys, just traded a Losi strike roller for a rtr brushless version of a T4.1 roller!! I am putting my 17.5 Xcelorin brushless set up in it so my question is where should I start gearing wise? Thanks.

definitely want arms and if you drive like me you should get ball cups and front shock tower and wings are always good to have spares of. spur gears sometimes

we were testing the brand new tracks jumps to see if we needed tweeks, full speed down straight a tamper was in my way, nothing broke the body just flew off

I only break when I am thrown in a wall/pipe now...

I really have never used boost. I was told that you should not advance timing on your motor if you are running offroad. Im going with an LRP SXX V2 with a 17.5 Revtech. I found that being consistent and running the same lines around the track will win you races. Its not always about being fast. Speed will come with experience. I feel running boost is kind of like cheating. Its pointless. If you want to drive fast, get a 7.5 and run mod. Not you, just saying in general :-)

thanks for the quick reply Brett!! i was sort of at the same opinion, i was just hopeing for the revtech to be some magical super motor that without esc timing could keep up!! lol my brother said i could use a rspro from his onroad car, so what would u gear a 17.5 (pinion/spur) at? i have every pinion from 18-35t, just no spurs lower than a 78 right now for a b4. cant wait for the clash

Question for those who went to the +8mm chassis.

Did you need to do a lot of adjustment to the suspension? ride height, camber, toe, shock oil etc?


My chassis will be here Wed and racing it on Friday with the new chassis

i personally had to retune most of everything, now the car drives much more stable.
