question regarding the shocks:

how often do you change your shock pistons and o-rings (single blue ones)? Do you normally change pistons once a season and the o-rings around twice or thrice in that season?

[QUOTE=jonston;12659851]has anyone on here tried roche dvs shock system on here yet? any comment? I know I shouldnt fix something that's not broken but would like to know if it makes some sort of difference.


Hi there,

I have just had these on the car for there first run and they certainly are yielding more lateral grip. I run in low traction outdoor asphelt. At this point it hasn't felt as reactive as the normal shocks. The shock itself feels really good, it's going to be getting the right spring combination. Early days at the moment but some positive first signs.

hello
I would like to know how the rs ver box stock work on med grip carpet?
Havnt found many reviews at all
17.5 binky stock
any info / help would be great

17.5t blinky stock on med grip carpet is fine, in fact i feel the whole RS ver of the car was designed for 17.5t in mind, however be prepared to swap the front spool out if you crash as it is VERY brittle.

overall im very happy with the car but has been an ongoing experiment of sorts to see what alloy parts are required to make it capable of running in boosted classes.

so far i have changed out the wheel hex's, spool, pullies, shock springs, spur gear to a 96t.

Hty guys, just wanted to drop in on the Yokomo thread and sharpe my recent experience.

Well, my Dad hooked me up with a BD7 last week for my birthday.

I don't usually throw statements out like this because they are so subjective and opinion based. But hands down, this is the fastest car I have ever driven on our carpet track. The difference is about 0.15 seconds on our current layout on hot lap, plus it is much more consistent.

I know I have heard about issues with the shocks before, however, we found some of our parts work with the shocks very nicely. No leaking, with a single o-ring. We will probably release a kit for them through the site, however, it was quite simple.

I used a m3x5x0.3mm shim in between our silicone o ring and the cartridge. I topped off the shock with our 10mm bladders and drilled the shock cap and had a perfect, consistent zero rebound shock.

I don't think we are diving into a full assortment of BD7 options in the future, but we'd like to adapt a few of our upgrades to be able to use on the car. Stay tuned.

That's interesting news, coming from someone who does a lot of testing on other brands
Perhaps you just nailed the setup perfectly the first time out ?

I don't know if one car is faster than another at our track, the BD7 just has a very intelligent, durable design imo, and it's at least as fast as anything out there

Thanks for confirming your bladders fit Cristian. I have a bd7 arriving Monday to build and was going to see what spare reflex parts I have were going to fit. It will be interesting to see if your Tc6.1 drive shafts fit as well.

Beth.

What springs does the RS come with?

gom

4 black springs of equal rate. but they have no labels, so i don't know what they are.

i just finished building my RS and i swapped those springs out right away.

i would be interested to know at least what spring rates they are.

Thanks, just what I feared. If my friend gets this car, I'll have him pick up a set of pinks and 2 sets of blues.

Red bull my setup is peter chus roar setup. I just switched to all graphite parts besides the c hub. I notice you setup uses plastic rear hubs?

Chris that is for mod on sweep tires with A LOT of traction. Change your droop to 7mm Front 6mm Rear.

Please, take my comments with a grain of salt. I don't think my word is the final authority by any means, but my findings were almost too good to be true. Speculation is exactly why I qualify my statements.

This past week I tested the BD7 in less than "perfect" carpet conditions. Grip was at about 85% and my lap times were consistently 2 tenths faster than with my RX4. The RX4 was by far the best set-up car I had driven on our track until this week. I have been fine tuning the set up for several months and on the particular layout all of last week I worked on a vast array of conditions to get the car really good. My fast lap was a 9.55 or so. I could hit 9.7's pretty regularly. This was on fresh rubber and with tons of track time. Track conditions were pretty good as well. I also must add, I only run mod.

The Yokomo I received Monday night and I hit the track on Tuesday evening. Ran 2 packs through it with mostly standard parts. I hit consecutive 9.6's for the first time with the layout and I had never had a perfect lap. On Wednesday, I focused on adjusting 1 thing at a time to learn about the car. I also installed some optional parts and carbon arms. Some adjustments made me go in the wrong direction, some made me get better. As I slowly started heading in the right direction I started noticing how much quicker the car got around the twisties. The car carried more corner speed and was easier to drive fast around the track. By the end of the night I was starting to hit tons of 9.6's, but the car was still not perfect. On Thursday I just made a few geometry changes and started going backwards. So I reverted a bit back and went to thicker diff oil. The car went from being a 9.6 car to a consistent 9.5 and a few 9.4's A bad lap was now a 9.6. All this was also on old tires, which made it more impressive as the Sorex 28's we run are much faster on the first 2 runs. The BD7 is easier on tires I think. With Sorex 28's, you get a lot of overheating and squealing on carpet, the more you squeal, the harder the car is to drive. The XRAY tends to squeal slightly more, which is why it probably needs new tires, with a hard sidewall to go faster.

The car for me generates better forward thrust than the T4. It gets from point a to point b better. This might not be as noticeable in stock, but in mod, it's huge. The car is also faster in smaller radius sweeping corners, where it digs into the track better. The XRAY requires a bit more finesse in this type of corner.

It is important to say that the BD7 probably requires sharper reflexes than the XRAY. It is more responsive, which probably is a better fit for me.

Both cars are fantastic, and in the right hands, both can be winners. However, racing mod, the BD7 is far more at home and it is more effective in achieving consistent fast laps at our track, with the tires we use. We do keep developing our T4 everyday. Now we have a higher benchmark in house with the yokomo to chase after.
