Good call.

Weavis see Toras quote... it makes it upper level due to the upgrade

Understandable, now Tora, what's your take on both of them? I presume you have had both if you know the positives and the negitives. And what about the Exotek chassis conversion?

and btw the Rsector is on sale for $80usd on tqrc riding website.

As far as I am aware the main differences are that the R Sector is a top loader battery compartment, it repositions the servo to the other side and moves the esc to the left side for better weight distribution.. The Exotek is a side loader battery compartment with a fixed top frame.. Money for money the R Sector is most practical and looks better.

That is a very good price foe the R sector chassis too

The R Sector also prevents any major wiring crossing over the chassis and keeps everything neater looking

My take?

The MS is a far superior version of the TA06 Pro, and Tamiya's answer to what people were doing to the TA06 in the last couple of years, since it's initial release. Two companies have come out with conversions for the TA06 since then - as R32Golf said.....Exotek and RSector. The MS is Tamiya's rendition of the Exotek conversion, since that came out first. The RSector is relatively new, and is different in many ways, not the least of which is it's rigidity. There is no way to adjust flex in the RSector, so suspension adjustments must be more precise.
The problem I see with the MS and Exotek, is the "swing away" electronics plate. I'm not a fan of swing away anything, and having any electronics that move is not a good idea. Which leaves the RSector as the only real alternative. The price of the RSector conversion is also a big selling point. If you are interested in the RSector, you can also get it straight from the manufacturer, which is based in Georgia, so you would get the conversion faster from them, rather than a vendor in California. The price is the same, so it would be up to you.

Even with the RSector conversion, though, you would still want some option parts, to improve the TA06's performance, whereas the MS is fairly complete, so there's that, too.

I've looked at some pics and can't see the sway away bit.. Is it where the servo is? And how do you adjust the rigidity of the Exotek?

It's the ESC plate. Something has to swing away, to remove the battery.

And any chassis that has two horizontal plates (chassis plate/top deck) can adjust flex by loosening screws that attach the top deck to the uprights it's screwed to. removal of certain parts can also do the same thing, but must be done carefully, so overall strength is not compromised.
A chassis that uses vertical plates is harder to adjust, if it can be at all, because the plates being vertical makes them act as trusses. The RSector doesn't allow for flex, because there are two thick vertical plates that have no play, even if they're loosened (believe me, I checked!).

I find my carbon reinforced chassis in the style of the standard chassis is very stiff too

Yes, that's because not just the carbon infused plastic, but the vertical parts of the molded tub for the battery. On molded chassis like that, there is a tiny amount of flex, but it can't be considered "active" like flex in a carbon plate, because there isn't enough to affect the way a chassis drives.
The flex in the stock TA06 chassis plate was kind of "wishy-washy" and really wasn't springy enough to improve performance.

If I had of known about r sector before, I would have got it and not wasted £25 on the reinforced tub :-(

Nah....don't be. You did O.K.!

The Carbon-reinforced chassis plate is world's better than the stock one. You would just be stepping up with the RSector conversion,

Thanks :-) so not all bad then, but if I did get the r sector chassis the tub would be defunct and not be used.. So is a bit of unnecessary waste of cash.. But there is a definite difference between it and the standard tub, the standard was very wobbly and flexible

That's nice to know, thanks for the knowledge guys, I'm looking forward to building one of these chassis. Idk if I want to start with the Sakura or the TA06 now. Lol. Making it quiet a decision but the price will be my final decision. Even tho the TA06 Pro is more expensive, I may go with that since it's got a bit more to it then the Sakura, I would have to buy quiet a few upgrades to put it on the same level. Tho Idk if it will overwhelm myself with such a complex chassis.

no worries.. if you have a look in the CSing a TA06 youll see my TA06 chassis and the upgrades I have done to date.. if you have any questions just ask.. You will not be disappointed with the TA06 Pro.. and the good things about it is that it can be set up as a drifter or a racer.. as far as I am aware the Sakura D£ CS is purely a drifter and not as user friendly.

Well when I was talking about the Sakura, I was referring to the Sakura XI. Lol. I'm not really one that's going to be going back and forth from drifting to grip, just purely drifting. So even if I went to the D3, it wouldn't bother me being only a drift chassis. I most likely won't CS the TA06, if anything I'd do that to the Sakura to make it a RWD CS. Something that would be far down the road since 4WD is mostly what drifters use.

My ta06 is purely drift and will remain like that forever

RWD drift is just RWD. There is no reason to "CS," since there's only two drive wheels, but it is also heavily dependent on weight distribution (moreso than 4WD drift), and unless the motor system is higher-rated that what is deemed "standard" (17.5TBL), RWD drift is also markedly slower. Steering servos must also be fast. That is a requirement for RWD drift, as direction changes must be initiated earlier than on 4WD chassis, to control the amount of "swingout" or "whip" the rear end will have.

I've never enjoyed rwd drifting.. Always a fan of all wheel drive myself

Really? Cuz some of the videos I was watching of the RWD drifting it seemed like the cars had CS on them for how smooth the tires were turning an staying steady in most of the drifting, and not overly counter steering the cars as most ppl would without an electrical system helping. But hey, I might be wrong, I have never done it before. Lol. Learn something new everyday!

Yah, it's only "CS," when there are four driven wheels, and two are "overdriven."

With RWD, only the rear wheels are drive wheels, so it can't be considered "CS," because the other two aren't driven, or under power. They're there solely to steer the car.

Well those guys make it seem so smooth. Haha. Thanks for all the information guys. Hopefully this thread will help others starting out also. Plenty of information you guys have given.

I'm glad your found the information useful :-)
