Tamtech Speed A Bit On The Low Side ...

[cmykhps 0]

Hi

I've built a TamTech 1/12 Porsche, and its looks good and I've been adjusting the tie-rods and stuff to get better handling .. but it's not very fast.

I had TL-01's a few years ago and I seem to remember them being much quicker than this. I changed the motor and the gearing and they went faster than I could control them

But the GT-01 just doesn't seem to have that zip.

I've read on here about brushless motors and stuff but I really don't know what that means.

Where would be a good start to getting more MPH out of my little car? The booklet says it has a 64T Spur and a Type 370 motor and I'm running a 500 mAh TamTech battery.

The dumb part about this is, they're just going to sit on a shelf a lot but I want them to be fast if I take them out for a blast.

a 500mAh battery is not much at all. my 1/18 scale car runs on a 700mAh (which will be upgraded ASAP). I believe a 540 or 550 motor will up the speed and power. if you want insane get brushless or get a new ESC that will handle motors down to 10T or unlimited and get a HOT motor. My ta02 with a 17T motor is a handful. it will not retain good traction on any surface but pavement and its top heavy. i think a battery would be a good starter. with a hot motor that battery will not last long enough for you to have fun.

hope i help

Definitely helped, thanks theres some stuff to think on.

I don't know if these small TamTech batteries can be obtained in other mAh values though. I remember running the TL-01s on 2400s. Need to get searching on the net

Will a 540/550 fit in a GT-01 Tamtech chassis?

2s (7.4v) Li-Po battery will improve it's performance some. You would need to find one that fits as they are smaller than the 1:10 batteries. 20C discharge rate.

I believe a 540 or 550 motor will up the speed and power.

The Tamtech Gear cars are micro size, using 370 size motors. 540 and 550 size motors are way too big.

You can get a decent speed increase cheaply and simply by swapping the motor for a Graupner Speed 300, they only cost around 5.

Brushless motors are just another type of motor, designed inside out compared to the more normal motors, with the magnets in the middle and the wire on the can. If you want a lot more speed from a micro class car like the Tamtech Gears then the brushles systems are the way to go as it is hard to get more performance from the pretty small brushed motors. The simple option for a massive increase in speed at a reasonable price is to look at the Dynamite Mini Tazer ESC and Dynamite C4 motors, available in different kv ratings, the higher the number the faster the motor goes. Works out at around 45-50 for the complete system. This extra speed will mean needing better battery capacity, you can buy packs for the TTG up to 1400mah pretty cheaply. Look for ones made of 2/3A cells, usually side by side, there are plenty around as they are used in almost all micro class cars.

Also check out the cars in the showrooms, there are plenty there that have been modified. Remember all the TTG cars use the same chassis so check out the TTG Frogs, Foxes, etc.

Some confusing replies here bar Terry's, so to add to his clarity :

- Taking a basic viewpoint, increasing the mAh rating of your battery does not alter the speed, only runtime.

- A 540 motor will not fit in a Tamtech car. In fact a 540 motor weighs about the same as a Tamtech rolling chassis.

For outright speed, brushless and LiPo is the way forward, but bear in mind that you are essentially modifying a small car designed for indoor running. There are some tradeoffs to be weighed up before you go down this route. The following is all IMHO and as a result of my own experiences :

- Oil shocks are a must if you don't already have them.

- The 500mAh batteries will be grilled in 2 minutes flat when running brushless. Upgrade to 1400mAh+ NiMH or better still, LiPo (NB: You will need different chargers for these packs).

- Driveability is affected quite dramatically. My TTG Frog needed a lot of work to make it even usable with brushless. My Buggy Champ is absolutely sublime and needed next to nothing. My Hotshot drives like you would expect a 1/10 Hotshot with 5x the power to drive (ie: Terribly, but huge fun...!). As as result, I'd say a 6.8kV system is plenty unless you are just drag racing. Even then it's hard work.

- You will go through tyres like they are going out of fashion and diff outdrives become a consumable.

- You will melt the diff (literally melt it) if you do a load of donuts. Fun, but avoid...!

- You will have a massive crash at full bore and be amazed that the car suffered little or no damage (Ref: my Buggy Champ at 60+km/h head on and perpendicular into a concrete wall).

- You will have a relatively minor crash and wonder why you car is in 47 pieces and needs a mortgage to pay for repairs...!!!

- To be fair, for the on-road cars, I have less experience, but I expect the above still applies.

- Generally speaking, you get what you pay for with brushless systems. The cheaper ones go very well indeed but don't get upset if a branded system with like-for-like kV rating is a lot faster. My Tekin Mini-Rage 6.8kV systems were on par with two friend's 8kV 'budget' Mamba systems despite me then running NiMH and them LiPo (7.2v vs 7.4v).

Cheers and good luck...!

maybe i should have researched that car first. i thought it was 1/10th. would a losi mini T or a duratrax mini quake motor fit in it? i bet you could get decent performance out of one of those. i think a 500mAh battery would be gone in about 2 mins anyways with a hot brushed motor. charging at higher aprages will affect the speed and punch right? i though that you would get a bit more oomph ot of lets say a 3000mAh then a 2400 or less mAh battery.
