| tc | xray t1 evo2 | vector x12 4.5t | c-hubs |
 

Hi all... I started a new project and felt like it would be a good idea to post it here so I could get some feedback or suggestions on the build.

Despite their small stature, touring have always amazed me with the high rate of acceleration and the ability to go through corners so well at some cray speeds... The high cost of acquiring one these kits
kept me at bay for a long time because I could not justify the spend... So I got me a used unit... I found this XRAY T1 EVO2 (seen below in first photo) on ebay for only $52 shipped... I decided to start
with a car that would allow me to go through the build process without confusing me to death... to appreciation the work that goes into these the little machines, I disassembled the car to get a closer look
at each of its components... I also went online seeking any info from other users of the car... though the the kit was released back in 2002, they were quite a few cars still being driven at club events with
relatively good success... They are now very popular with the drift community... I also found out that they were five other models Designated 'T1' from xray that would facilitate cross use of parts and upgrades:

XRAY T1
XRAY T1 RAYCER
XRAY T1 MINI
XRAY T1 FK and XRAY T1FK'05 (which is similar to the current layout of the T2's and T3's Chassis)

I decided to go shopping for some upgrades and accessories for the build... Luckily, Xray still lists the parts on their site... unfortunately, most of the hobby shops I got in touch with did not want to do business
with me because my shipping address was not the same as my billing:whip:... So, I had to go searching on ebay again... very limited options for the T1, but good deals will pop up every now and then..

Parts acquired:
Aluminum C-Hub suspension option set - rear
Aluminum C-Hub suspension option set - front
Anti-Roll Bar front and rear 2mm sets
Belt Tensioner Set
Multi-Diff
Solid aluminum central Layshaft
Blue - soft-medium springs

Beautiful....
 

Simply beautiful...too pretty to put on the street.

Thanks man... It's going to get dirty!! I want to race it at the local track with the nitro fellows and see how well it will keeps up with them.


Alien

Theres a lot of nice shiny bits on there Alien.

Nice work. :)

Thanks Bush:yes:... did you get yours yet? When you do, post up some pics...

Alien

Run with a 3s Mamba Max Pro with a 5700 and they will ask you to leave the track....that is if you can control it.:yes::yes:

Hmmm.. well that's the thing... I do want the control... so I opted to stay with 2s and the current esc and motor combo... I have seen one guy with a TC4 running a Castle 5700 motor at the track (i think on 3s) and that thing is a handful... needless to say, corners are a little challenging for him with all that power going through the wheels... The objective of this build is to keep it within TC spec as much as possible... nothing over the top on power... My friend Bush will be running a the setup you suggested, so we'll see the difference when they finally get on the asphalt...

Bushboy, hurry up with your build man!!

Alien

got a nib cm36 9000kv motor if anyone wants to take a tc back to the future lol! have ran some tc on a 5.5 on 2s and it ripped, cant imagine more power but i guess that is why we are rc-monsters! seriously though that is one sick ride. x-ray has always made stellar stuff in my opinion. was never fortunate enough to own one, but have ran a few other fellow racers x-ray rides and was seriously impressed. just a little rich for my blood. dont think you will have any problems with the nitro cars, except as back markers. keep up the good work alien, tc will reward you with an amazing driving experience and hone your driving skills given proper setup and attention to detail. in other words lots of patience..........probly why i went back to off-road.

Thanks man... It'll be a steep learning curve for me as this is my first TC, but I like a challenge... it's going to be 'fun'... I hope... can't wait to finish the build.

Alien

I also love TC...but alas, no one to run with. One local high school just had their p lot repaved last year and it would make a sweet on road layout.

It's in the shape of a rectangle..it has 180' straights with 95' ends...I measured

your build wants me to get one again...if I wasn't doing a Slash 4x4 make over, those would be on my list

No pics I'm afraid Alien, still waiting on that camera. Maybe you can get some good ones at the weekend and post them. Not as many shiny bits as yours, so yours will look faster.

'look faster' huh? :lol::lol::lol:... finish your car, and we'll settle this at the track...

Alien

I'm just waiting on my little green can to get here :)

The electrics
 

Ok... so I got the electrics installed now... this was not a simple task considering the size of these little cars... it's a good thing the LRP Sphere TC Spec has got such a small footprint...
it was small enough to allow a little space for the receiver to mounted next to it... The motor, power and sensor wires had to be strapped to the upper deck since the battery will be mounted
horizontally between the esc and motor...

I plugged everything up and programmed the esc's neutral, forward and brake positions (this esc does not have reverse)... It works... the fan is a little loud though for its size (it spins up really fast)...
all programming is done on the esc with the mode and set buttons... all mode features are confirmed with LEDs.

I'm still waiting on new spurs and pinions... so I didn't get to run a full test with the electrics and mechanics... see the pics below for the current layout..

Not a whole lot of space for mounting electrics on this chassis... the deans will be replaced with 4mm bullets for the protek 2S packs

To be continued....

Shoes
 

Got the new wheel and tyres glued up... they'll need be balanced before I run them... so I used the stock ball hubs and shafts that came with the car to make an improvised
tyre balancer... as soon as I get my new gears, i'll know how effective it is... see the pics below...

Alien

Update... :yipi:I finally got my batteries (Protek hard case 50c 5000mah 2s) and new gears (99t, 93t, 22t, 23t and 24t)... got them all mounted up and did some small tests with mechanics and the electrics... everything seems to be running well together so far... I hope i can get it on the track this weekend to see how well it runs...


See the photos below:

velcro was added to the lipo casing and battery hold downs to reduce the chance of the lipo sliding around... the hold downs were
also raised via 2 x 2mm (4 in all) shims to allow the packs fit comfortably

having a little fun with the throttle... the motor gets to top rpm very quickly and it does so smoothly... low speeds are nice, no cogging

Alien

Stunningly beautiful..

Thanks man :yes:... I am really liking how it turned out... kinda feeling bad that i have to get it all dirty now :lol:, but i'm sure it'll be fun... I downloaded some setup sheets
and started working out the suspension in preparation for the weekend... these little touring cars are so technical...


Alien

Really cool pics there Alien! Great car!

Thanks :yipi:... I had lots of fun doing them last night...

Looks GREAT! Those are some very nice shots you've taken. :yes:

About that Racer's Edge servo arm. Can you tell me if the linkage hole is tapped for a 3mm Screw or 2.5mm?

Also, How does the Locking spindle part work out, does it clamp around the Spindle and Also use the standard screw to hold it on the servo ??? 4 total screws? Thank you, Sir.

Hey Zippy, thanks man... the servo arm uses a 3mm for the spindle hole... most of the holding force is created by the two tiny screws that are mounted through the sides of the clamp...
I used the M3 screw to push the arm down over the spindle because the initial fit is a little tight... If you want additional holding power from the M3 screw, you will need to shim the inside of
the spindle hole... the linkage hole is 3mm and you will be using a total of 4 screws...

see the link below:

Clamping servo arm


Alien

Pics and car : work of art ! :yipi:
Protek lipos are great I really like mine you won't be disappointed !

Thanks Popoxx :yes:... yeah, these lipos sure pack some punch... it's been raining here for a couple weeks, so no test runs on the track..
I did some runs on the carpet at office a couple days ago and it was whole lot of fun.. i'll make an update as soon as get the car on track.

Alien

Those are great motors! And you can run them well into the 200's every run and the rotors hold up. Mod touring car is the bombb

Yep... it's got real power alright... i took it out to have a run today... it was a hand full man... sick sick acceleration... man this thing was a handful... handling was a little tricky...
so I have some work to do... but i must say, THIS THING IS FAST!!! :lol:...

Alien

Looks great Alien. That reciever looks like it might get a bit wet in that position if you decide to drive through any puddles. You might want to try sticking it on top of the servo to keep it warm and snug :na:

Very good pics mang. The ones with the drivetrain spinning is my favorite.

Yeah, so true... in fact I just had the receiver fail after running through small puddle during practise on Sunday... I won't be doing that again... the moisture seems to have knocked out the throttle channel...
I'm sending it in to Airtronics for repairs...

What's going on with your build? when are you going to post up some photos? I made some changes with mine... I'll make some updates later today..

Alien

Thanks man... those tiny motors are so powerful... the noise is just wonderful too...

LRP are my favorite sensored motors. I have the x10, x11 and x12 and all great. But the C40 Hacker motors are still fav for my small cars. Spools up quicker and run cooler. They don't have the cool sound the slotted x12 has though.

What are you running the x12 in? Driving this little car is not as easy as I thought it would have been... fun, but not easy...

I use the run the x12 3.0T in my CRC genx 10 pan car. I was using 2s2p A123. I later stuck the motor in my Rustler on 2s and for fun in the CRT.5. I still have the motor in my collection.

The little cars take a bit of tuning to get it right. Another reason I like the older pan cars for the ease of tuning. Having the right body for downforce makes it easier to drive for me. They are alot of fun.

Wow... 2s with that motor must be crazy!! do you have vids of it?

No vids. The 2s action was done with the RX8 and Luciano's ESC. In the pan car with the A123's, the esc was from Luciano as well. I didn't have the guts to run the motor with the mmpro or rspro.

Motor got pretty hot in the crt.5. It would've faired better if the rotor had a fan attached like the 2.5T motor that I have. The 2.5T was fun in the crt.5, but I popped a A123 cell(was and old and abused pack).

You probably seen the pics before.

Nice... not a who lot of space to work with in pan cars... is that 1/12? i am sure that motor is way much for that car... sure looks like a blast though :yes:

That pan car is 10th scale and a blast to drive. Excuse the crappy pics. They are not as nice as yours.


My other old pan car are easier to drive

Nice collection man... well... when I have tuning issues with the lrp, I will be coming to you for some advice...

A small update...

I received the body recently, painted it and got on the track on Saturday... damn, this little car can fly... I got a couple new sets of tyres too (slicks)... Sorex 28R, 30R, 32R, 36R and a set of 40Rs...
the higher the number, the harder the compound (this what i have understood from some reading)...though they made the car handle a lot better, I still have a lot work to do regarding on my driving...

I was really impressed with the performance of the car though... when the tyres heated up, it ran like it was on rails... I got a little over confident at times and pushed the car beyond its threshold...
one bad corner lead to a broken rear control arm which was relatively easy to fix the following day... Sunday i went back to the track to get some time on the asphalt, but the track was a little busy with nitro
guys practicing for a race... so i decided to wait for the track to clear before going to get my laps in... in waiting, i got a little bored, so i ran the car in the parking lot parallel to the track straights... from a
standing start, the car was fast!!! it easily overtook the nitros that were already rolling.. little did i know, the car picked up a stone and flung it on the front belt leaving a big cut across it... the belt did not get
past the first lap of my practice... so, more down time before i can get some laps...

Photos of the painted body and 'battle' scares:
