well, its a ruffly though

lets began
a TA05 has a 105/40/64P gearing, with modified equal length belts
with 7.4v 40C lipo,
the motor is NOVAK 3.5Turns 10500kv and the ESC is GTB spread spektrum compatible
reached 96kmph

hmmmmmm lemme get it clear,
i want to kill the 200kmph limit with in a short track length, with the same lipo voltage

usually a bigger tooth number pinion and/or smaller number spur gears
will do the trick in a price of over heating in some kind


ok !!!! i've replaced the gears with 47pinion/ 49spur/48P ( almost 1:1, FR is almost 1 )

hmmmm the acceleration is not high< obviously because there is
no enough track length to reach the RPM
and suddenly, smoke out of the bodyshell
the capacitor ( stock 5200mF 10v) is totally smoked saving the GTP ESC) thank god
and the cooling fan is affected too,

well i have spare CAPACITOR and FAN, no problem, a friend of mine said change the CAP mF number to higher and voltage limit to a higher , well I've prepared two 4700mF 35v CAP's and il solder it later,

the issue is one thing , after changing the gears to its current what is the side effects ????

again the SPEC's
TA05
NOVAK GTB spread spektrum attached to a 3.5 Turn 10500kv
47pinion/49spur/48P
modded equal belts
7.4v 2S lipo ( 40c ) 200constant amps and 400 burst amps
custom upped deck and wheelie bar( aluminum)
think of this scenario and give some theories or explanations


NOTE : I've heard also CAPACITORS reduces ESC noise and TEMP along with saving non-equal voltage sucking to the ESC



also any help in gearing explanations, web sites, pre-experiences, threads, are needed
please dont just pass by this POST help to understand

That sounds daring. =/

But anyway, make sure:
- your electronic have ample cooling.
- shell have proper aerodynamics (we don't want it to go flighting do we)
- and ensure that your servo can handle the stress.

Your main enemy would probably be aerodynamics.

And don't forget to properly set your steering!

Goodluck to you....and your electronics.

(I was writing this last night but got too sleepy to finish it)

Correct gearing is very much important with regards to motor capacity and load applied.
Load being the weight of the car - which why gears are used - to lessen the load to the motor.

I think it's better to use a 3S or 4S li-po and a capable ESC..

I'm not sure about the FDR that needs to be used but I'm guessing it would be between 3.5 to 4.0 but definitely not 1.0 or 1.5. You'll fry your electronics for sure. "pooof! it became coco crunch"

Capacitors, from what I know, only stores electricity and helps during motor start-up. Like a jump-start for the motor. I don't think using higher capacitors will help you with this.

another point: with a TA-05, with it's relatively short wheelbase and if aerodynamics is wrong, you will see you car flying even before you reach 120 kph.. A small bump could mean disaster.

there are lots and lots of thing that needs to be considered to achieve this goal of yours..
1. weight
2. aerodynamics
3. a really flat and clean area to run


like what greg said, you have to be patient with reaching your goal. take it one step at a time instead of leaping the whole yard.. there might be dogs that bite if you fall down.

Let me sum up your problem.

You will NOT see 200km/h with this car - there are at least 4 solid reasons why you wont. Aerodynamics, weight, build and resistance.

You will NOT see 200km/h with ANY car in a short distance.....there is a very solid and plausible reason why the Bonnieville salt flats are used as the choice for land speed records. Getting the FDR close to 1 will not make it happen in a short distance, unless you have the kit to handle MASSIVE power, VERY quickly.

I know I sound negative, but facts are facts....

I have to agree with Carthuga here, please see the LINK to see the time & effort and specialist design put in to break 200km/h in an RC car

Granted, he was looking for 200 MILES per hour, which is a bit different, but still....

I think 270km/h would be terminal velocity at gravitational acceleration....why dont you lob it off an 8 storey apartment block....it should get 200km/h by the time it hits the ground...based on this experiment, you could also work out the amount of damage it will sustain, similar to if you lost control of it ( likely consideration)

u will also need to put into consideration what certain parts can sustain because at cerain speeds u migt not know if your belts, pulleys, dogbones, bearings, tires and all rotating parts will be able to sustain extreme RPM, it took me about a year to be able to make my baja handle 160KPH on flat sand, i took into consideration about every aspect of what could go wrong.....from losing a wheel up to bending the chassis from downforce, there really are so many factors which is why alot of testing needs to happen, but never give up, thats why i am where i am with my results 160KPH OFFROAD!!!

ohhh lots of things to be considered !!! il try to step back a bit and have a constant upgrade bit by but



tomorrow is another test


Please advice even more !!! technical issues are desperately needed !
