WLToys 14401 is a 1:14 buggy that, out of the box, comes ready for 75km/h action.
It's quite the thing. The power is such that the chassis is aluminium from start.
This is the little brat I'm talking about.
Problem with that is that everything else is vinyl and, at 75km/h accidents tend to make things definitive when it comes to bending the chassis and pulling the threads out of the screws holding things together.
I should know... I brought one, My friend Marco bent it, I replaced with another chassis, my kid Miguel bent it... so:
THIS IS MY 14401:
Cover has been cut to accomodate and ventilate the 80 AMP surpass hobby ESC
I've also cut the airway to the motor active cooling.
Full metal differentials and differential housing
Full metal wishbones
SurpassHobby 80A esc
Better Servo
Surpass Hobby 5200Kv motor
Front foam lip to absorb impact
carbon subframes
ESC tied down and tidy next to RC module.
3S battery and some on-read wheels.
Full carbon chassis, no more bending
This was something else as a 2S 75km/h car, but like this, it is very very promising.
First tests indicate that it is powerful, because I've added High grip tires and making a few pulls off the line, it completely unscrewed the differential satellite gears, making me have to open and re-screw them with tighter torque specs.
At 160 USD the ZDRacing ZMT-10 9106 is considered by many, as the best sub 200USD 1:10 monster truck you can buy.
It comes standard with a 3300KV motor and a 45Amp ESC, good for 60km/h out of a 2S battery.
HOWERVER, I already brought mine with 5400Kv and 60Amp ESC, plus, the 3S.
This means that my car, from the start managed, not the 60KM/h 24420 rpm, but an astonishing 60480 rpm. This means that each RPM is responsible for 0.002457002 km/h.
So, following a direct propositional math, my car was able to reach 148.599 km/h from the start.
This meant several things:
1 - Self unscrewing screws - easy fix with nail polish to hold them in.
2 - Twisting chassis - fortunately there is an aluminium version to buy part for.
3 - After fixing the chassis, the wishbones started to flex and the towers too. So full metal suspension parts + towers
4 - Broken semi axle - The next thing to go was the semi axles, so I brought more robust ones and coupled with aluminium hubs to match... now the chassis is all metal.
5 - So the suspension started to act and me ineffective. OK, double shocks with oil reservoir.
6 - Finally.. it went too fast for turning, so let's make the wheels bigger and the car wider. Some spacers and 1:8 wheel s fixed this.
The Car got way bigger and wider, and the speed was so insane that I managed to destroy the cover, so a new one was installed as per the last image.
The result, way more than 150 km/h, as the wheels got bigger and so the motor gear, so this is close to 200km/h now:
It all starts with the TT01 Tamyia chassis copy from the majority of Chinese manufacturers.
I chose the PMM chassis because:
1 - it has a aluminium propeller shaft
2 - if has aluminium wishbones instead of vinyl ones (however if you are not used to the power of a beast like this, I recommend you buy the vinyl one and later replace the wishbones.
All these chassis come with plastic wheels and plastic main gears. Ditch them, They will crack with the power and fail. Buy Aluminium wheels and SOLID tires. Use Super glue to bind the tires to the wheels.
Replace the main gear that connects to the motor gear-head with metal ones.
Choose a powerful servo, the rotational speed achieved with this setup is so high that the wheel s will try to keep straight and 3KG servos will not be enought.
use either super glue or nail polish to Fix EACH AND EVERY BOLT
IMPORTANT - YOU WILL NEED engine coolers and high capacity 3S bateries.
I'm using GXF power 5.2Amps because they are light, durable and powerfull on discharge.
For the R34, I Equipped the car with a 60Amp ESC (platinum) from surpasshobby and a surpasshobby 6000Kv motor
The real world S2000 is known for High RPM engine, so I managed a 150Amp ESC from SurpassHobby coupled, with an Ansmann racing 3.5Turns (10800Kv) motor
R34 cover on and the s2000 is still under preparation.
The result is a VERY chalenging to drive set. Here is the r34 tests with a slick concrete floor in the garage, the s2000 makis things even more chalenging, so I changed back from 2WD to 4WD.
And side by side with the little brother, a WLToys144010 transformed (something for a different article)
and the ZDRacing 1:10 truck, again heavily transformed (another article).
More will follow as I keep modding these babies.
Ok... so the S2000 is waiting on an even more extreme motor and ESC for a good 11000Kv, but I hated the color and overall "cheap" look of the body. So Today we dedicated some time to it:
Carbon Wrapping on the red and china-made body.
Look something else, now.
Back to 4WD conversion...front diff comes out, shaft, mounts and half shafts go back in. It's hard enough to control as a 4wd, let alone as a 2WD.
Rubber tires out (they where coming out in pieces anyway)
Foam Tires go in... and super-glued to the aluminium rims.
Chassis screws re-painted with nail polish
Leds Installed and... Voila
The 35 Kg servo is a beast... let's test the response:
NIIIICE
