RWD THEORIES
#1
Theoretically speaking , 

How would any of these two ( http://www.hpiracing.com/en/kit/112862 / Sprint 2 Flux BMW M3 GTS ) - ( http://www.hpiracing.com/en/kit/106168 Sprint 2 Flux BMW M3 GT2 ) HPI cars compare on an indoor track to the RWD Sakura or YOKOMO RWD class if the HPI cars ( STOCK ) , were converted to RWD with no other major modifications with an exception to drift tires ?

Alternatively , how would the HPI cars handle with only a drift tire conversion and with NO RWD conversion against the Sakura or Kokomo on a track ? 

This question is a theoretical one , i am new to the world of RC drifting and my knowledge on RC drifting cars , while expanding greatly daily , is still weak . Forgive me if my question seems stupid .

The reason for my question is to understand the basics of why HPI cars can't compete with products like RWD SAKURA and RWD YOKOMO , is it simply because of the RWD factor ? 

Why couldn't i simply slap on some drift tires and convert the mentioned cars to RWD and outshine the other rides ?

Does it not work this way , am i missing something ?

Hope someone can help in educating me on the subject , thank you .

All advice and comments are welcome , I'm here to learn .

Thank You .

Again, you are asking the same questions over and over again, if you are willing to spend more money, get the yd2 (plus if you want to spend $300), if you want to spend less get the D4. I assume you want RWD and not Awd like those hpi's. You can't compare the hpi's with the others because they are awd and yd2/Sakura is Rwd.

Sorry Millsicorn but i think you're missing something , are you aware that the HPI Sprint Flux 2 has a RWD conversion kit ?

http://www.yeahracing.com/catalog/spt2s0...-3997.html

I've yet to receive to definitive answer to my question , once I do , i won't keep simplifying the question and asking it , thanks for your time .

P.S

My question isn't about affordability , the funds are available to purchase anything I see fit , I'm trying to learn how the cars would compare , once converted to RWD fitted with amazing drift tires and placed on a track with a D4 or YD-2 !

I truly hope someone who has experience with the Sprint 2 Flux BMW M3 GT2 and GTS versions can compare them with the D4 or YD-2 .

Regardless , thanks for your time and effort in attempting to guide me , however you didn't answer a single question i asked , lol . Thanks .

The HPI is basic a car for touring/street driving. It is most compared to a Tamiya TT-01 but it doesn't get much better because they are not build for drift, that said, any car can drift with drift tyres - But it's the way they drift that differs from other manufacturers. The HPI cars can handle 50/50 (All drive drift) since they don't have much lock on their front wheels and to try and converting them to a rwd is just money and time down the drain.

A HPI with drift tyres and 50/50 style would be the same as a Sakura or Yokomo on the track, but it get's more complicated, but first, let's talk about the 3 styles there is in motorsport and drift:

1. 50/50 Drift or also known as Rally drift - It's basic all wheel drive and powersliding, you know Ken Block still does it, since he has done it since he started Rallying.
2. Counter steering drift - Underdrive in the front, making the rear spin more and automaticly creates oversteer and to control it = Countersteer, hence the name CS Style)
3. Rear wheel drive - The car is pure focused to mimic RWD, by that exeption that it is helped on by a gyro since in real life you have senses of moving, sliding and feeling. In R/C you only got your eyes and no feedback from the controller so the car does something, you see it, you process it, you send it to your fingers and the radio transmitt it to the car in about 0.50 second and that's too slow. So a gyro helps with the initial steering, the reaction and then you focus more on the throttle because that's the next most important thing in RWD drifting.

When R/C cars are driving, the motor placement is important, to explain i'll use a scale from 0-100/0-100 for weight and handle performance:

A HPI Sprint 2 is rear biased, 35/65 since the motor is back it will rotate the rear first, high grip.
A Yokomo DP is center biased, 50/50 since the motor is center it creates neutral balance and equal grip.
A Yokomo DIB is front biased, 60/40 sice the motor is front it will rotate the front first, less grip.
A MST XXX-D is similar to a Yokomo DP.
A Sakura D4 is similar to the Sprint 2, MST RMX-D S/Pro
A Sakura D3 is front biased, 80/20 since the motor is in front of the axle it will rotate the front very fast, less grip.

To fully understand the pattern, the position of the motor plays a big part in drifting and styles - myself is loving my MST XXX-D, but i previously have owned a Tamiya TT-01D (50/50), MST XXX-D Pro (50/50), Yokomo DP/DIP (50/50-60/40), MST RMX-D VIP (35/65) and now finally my XXX-D VIP (50/50).

The biggest thing you should know it that R/C cars that is not developed like a drift car won't drift RWD properly unless you invest a lot of money into custom parts. A MST, Yokomo, Sakura that is built for drifting RWD would be better because they are designed for it, and out of the box are capable of drifting good, though the Sakura doesn't offer much since it's more budget than quality i would recommend a Yokomo YD-2 or a MST RMX-S (soon to arrive) or a FMX.

I hope this help you into the big drift R/C community world :)
MST XXX-D VIP - CS 2.0 - Main

MST FMX-D PRO - RWD - Main

MST RMX-S 2.0 - RWD - Secondary

If converted to RWD and tuned properly with the Yeah racing kit it would do just fine against other RWD chassis. 

Alternatively , how would the HPI cars handle with only a drift tire conversion and with NO RWD conversion against the Sakura or Kokomo on a track ? It would be quite the rocket and you would have a lot of trouble getting along with other RWD cars. Tandem would pretty much be out of the question because of pace and angle ability difference. 

This question is a theoretical one , i am new to the world of RC drifting and my knowledge on RC drifting cars , while expanding greatly daily , is still weak . Forgive me if my question seems stupid .

Is it simply because of the RWD factor ? Yes and No. you also have to factor in tuning and driving experience. But what will get you on par with others is matching their drive type first (AWD, CS, RWD)

Why couldn't i simply slap on some drift tires and convert the mentioned cars to RWD and outshine the other rides ? You can! The only two real obstacles you will have is part availability, and tuning ability (Which will be gained as you grow in the hobby). Sprint 2 parts, aside of the Yeah Racing kit, are somewhat hard to come by. You will have some hunting to do. Then to outshine others you will have a lot of driving time to clock to make sure you're driving is on point and so is the tuning. But it's doable.

Though I don't agree with everything that Woodsnail said, this part of his response is really what it boils down to. Today's kit are really no brainer and if you are just getting into the hobby they make for a much more enjoyable experience than trying to bring up an older chassis up to specs. If you have not bought anything yet, don't make the mistake of buying a sprint 2. However if you already own the sprint 2 and are looking to go RWD, then save yourself some cash and get the YR kit.

Excellent response , both of you have truly helped guide me and i feel as though I've learned plenty.

The mentioned YD-2 and its variants along with the MST RMX - S are out , and although i initially never planed on purchasing anything but an RTR , todays options from MST , YOKOMO and others are extremely tempting. I'm SERIOUSLY considering purchasing one of the mentioned kits.

The sad thing is that most of you don't understand that not all people are like you , while we might be great at what we do on a professional level not everyone can put together car kits. Believe it or not I can't fix the TV remote without shattering it to 50 pieces , its simply who i am. So take that into consideration when advising me, lol.

Other than the MST releases , the Sakura D4 and the YOKOMO YD-2 (YD-2 EX) , anything else in the market that i should keep my eye on or check out ?

I've been strongly advised to stay from Exceed , HPI and a few other lesser known brands , not because they are bad , but because they simply can't outshine what YOKOMO and MST and Sakura has brought to the table , and so please correct me if I'm wrong on these points.

Right now as it stands... Im looking at YOKOMO , which has always been my favourite brand , although i never owned anything by them. Followed by Sakura which i believe to be the best in terms of reputation based on my observations and the MST in 3rd based also on rep and research.

In reality though...MST is the only one of the bunch that makes an RTR , and the RTR MST makes isn't on the YD-2 or D4 or MST RMX level , correct ?

I did say my preferability was to purchase RTR , other than the MST RTR , anything you'd advise me to look at in terms of RTR ?

Which RTR would you purchase (OPEN BUDGET 1000 USD) ?

Thank You for your time , looking forward to your feedback and if you have time , PLEASE , share your experience with HPI , i am truly interested in knowing why they get hammered online , the website HPI has going on , paints them as the leaders of this industry , track wise , seems to be a much different story. Im so curious to know what the best HPI drift out there and how does it compare to others.

Thanks Again...

If you're going to want to tandem with people you wont be able to do it in the sprint 2. Theres not enough control for it since its 50/50. I've heard of those countersteer and rwd conversions for it. Its up to you if you want to put time into that. Idk if its worth it since i've never done it. But there was this kid at my local rc track that had the rwd conversion on his sprint 2 but ended up just buying the D4 because the sprint 2 was very limited to its angle and compatibility with parts from other brands.(Remember rwd takes A LOT of tuning) I have a hpi e10 i converted to cs. Wasnt really worth it. Tried rwd on it and it was hell. And now converting it to a rally car which ive done before and turned out great. With that said hpi just isnt up to par.
I would go to your local drift track and see what everyone runs. Cs or rwd. This way you wont regret your buy later because its way funner with more people. The track here is focused on rwd so i went with the d4 rwd. Just because it was cheap and i always wanted a d3 and this was when the d4 was first released so i hopped right on it.
It just comes down to what you want.
If you just want something to mess around with and nothing competitive at all. Sprint 2 is good.
If you want to really get into it and tune and actually be able to tandem. Something rwd or cs. Not telling you what chassis to get cuz i only know about the d4. Maybe theres something else out there that seems better for you.
Hpi E10.CSD
Sakura D4 RWD

Thanks for the response , Im defiantly not going with the HPI , I'm sticking with the one of the top 3 in my opinion , YOKOMO YD-2 OR the MST RMX S 2.0 / RTR'S , or Sakura being the 3rd choice. RWD is where its at , its what i plan on purchasing, Im in the middle of moving finally and that is the reason i can't depend on local track sources for guidance. Completely different side of the globe !

I have a question on the D4 RWD since you drive it and its one of my top 3 choices...

Im going to DM you...
