Default TA03F PRO FOR SALE!!!!!

I have a TAO3F PRO that I have assembled for sale. The car has never been run! No electrics have ever been installed. I haven't even glued the tires. I have the original box and a few hop-ups (spring kit, TAO2 hubs, alum motor heat sink, etc.) Not sure what to ask for it. If anyone is interested please let me know by sending me an email. Maybe a deal can be worked out.

Thumbs up ZXT reply

Yes...a twin motor assembly on a TA03 chassi.
Originally, it was a TA03F. So, I decided to install another motor at the back of the chassi using another front set and installing it instead of the original rear set. It was very easy to do that, as all the mounting holes matches the ones present at the carbon chassi. The problem is that the performance now is just the same as it was with a single motor, and I coudnŽt find out why...
I have a picture, but I need to look for it. As soon I find it, IŽll let you know, ok?
IŽve also created a forum to deal with this problem (Twon motor assy). If you know anything about this, please help...
Later.

Twin motors!!!!That must be fun!Try gearing it longer to get some speed!

Default twin motor problem

are you running the belt still? your motors may be "fighting" each other if not closely matched, therefore trying to make the belt skip a cog. if you're not using the belt anymore, you're in for a lot of headache. ----> if your motors are not at least very closely matched, you will have handling probs. one motor pulling harder than the other will either pull the 2nd to effectively "drag" the other's wheels or, worse yet, break traction on its' own two wheels from being held back(this can be proven by trying different dia tires on the front than on the rear of a "normal" car.) another prob could arise if the power curves of the motors are NOT the same. thus causing the car to be ok at top speed, but squirely under accelaration and vice-versa. to further complicate things, part of the acceleration curve of the car may be ok, but another may be way out. in other words, achieving consistency may be a nightmare. if your motor wires are not equal length and gauge, one motor will recieve a slight bit less voltage than the other due to added resistance(which will kill any motor matching efforts.) i could write a book on how trying to run two motors "working independently" of each other is futile. are you using two esc's? more matching probs there. if running only one, you may blow the thing considering the amperage draw will be twice the amount of one motor. batteries are another thing. wired in parrallel = 2x mah rate. wired in series, twice the voltage w/ same mah rate. can your esc handle the amperage draw of two motors AND 12 cells? just look at the full scale racing world. how many high performance racecars have an engine for the rear and an engine for the front?

Try gearing the motors up to find better performance. I'm guessing you already have good acceleration now, but top end remains the same. You could take advantage of the added torque from the second motor to share in the torque load when you use the second motor. Hence my theory for gearing up.

As for real cars not utilizing twin engines, well, the thrust-to-weight ratio really isn't as favourable, I guess. And its probably not worth the effort to find the place to shove another engine into the chassis.

It's me and my obsession again (is the word obsession correct???)
Anyway, I found a pic of my chassis - it's an old picture...I'm taking some new ones with a digital camera (will be posted soon)

Sweet trailer man! Your twin motor ta03 looks great too. I recommend using two esc with two motors and gear higher that usual. You will notice the increase in speed. What motors are you running?

Default Twin freak

I'm trying to run two Dyna-Run Super touring motors, and I have a LRP V6 ESC. I was thinking about having a second ESC, but it'll be very expensive (since here in Brazil the dollar values 2.7 times the Real) - and with theese things going on your country, it's expected to be worse here to...

Here are some tips of my super F150 Lightning:
- working fog lamps, headlights and taillights;
- working license plate lights (made with fiber optics used in an old toy bought at Disneyland...)
- Working brake lights (even the high mounted stop lamp) due to a burnt Novak Explorer installed inside the body
- Side mirrors from the Audi A4 body (destroyed by now)
- I changed those original wheels for Yokomo 5 spoke chrome wheels
- Disc brakes (fake, of course) from Yokomo

The trailer is made from balsa wood and the bike is a BMW RS1000, but i'm working now on a Yamaha R1 (Tamiya) to replace it...

Default Traction Roll Problem

Hello guys!

i have a traction roll problem with my 03f.....

it always happens on hairpins or fast 90 degree sweepers...

the inside wheels always seems to want to lift up if i charge on the turn too fast....there is no irritating understeer or oversteer happening when it does this. it just flips over in the middle of the turn...

here is my setup:

ta03f chassis
tamiya superstock type-t motor
5.41:1 gear ratio

Front:
Low friction alum shocks with blue springs and 30wt oil (kit oil). 2 big spacers...1 o-ring limiter inside the piston.
0 degree toe in.
1 degree negative camber
blue sway bar

Rear:
CVA mini damper with red springs and 30wt oil. (kit oil). 1 big and 1 med spacers...1 long plastic limiter from part tree inside piston...
stock toe in
2 degree negative camber
red sway bar

tires
HPI 35R

insert
hard shaped insert

TIA for your help!!!

Default Pinion gear ?'s

Whats the stock pinion of TA-03F? Whats the compression ratio of stock TA-03?

Again how do I compute for compression ratio?

Thanks
