hi , i'm looking for some advice here please , i've got a 1/10th ta 02sw chassis with a mabuchi rs-540 sport tuned motor but i'm looking for more speed . i'm not going to pretend i know anything about these things because i know nothing.........

anyway i've found this , http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&am... are these any good ?

i've been told that i should buy one of these ,

http://cgi.ebay.co.uk/50290-Tamiya-RX-540VZ-Techni...

For a budget speed control we supply Ansmann ones in the shop and they look just like the Mtroniks ones which seem reliable for the money. They do a controller with a 12T limit and we retail it at £34.99 iirc. It is a forward/reverse system unlike some which are forward only.

i'll have to watch the forward/reverse thing then............cheers for that........


i'm not really on a budget , just looking for some speed without going nitro powered .

The Ansmann are good value for money, ( a complete ready to run truck in only £100 retail) I use the Mtronics esc in my cars and they do seem to last well, and as Mikey stated they seem to be identical to the Ansmann.

Depending on what you want to do with the car, i may also recommend something like an Ansmann motor. they do the similar closed can fan motors with a 21 or 23 wind. That will give an additional 4-5,000prm.

You are then starting to look at top speed vs acceloration, and entering the world of gearing.

Don't forget that if you go for an extreme motor (30,000rpm is quite extreme) you are putting substantially more pressure on the gears and driveshafts. make sure these are in good condition before you go pop.

cheers for that , i'm looking into up-rating my gears/drive shafts and prop , and some other parts too , i'll get a pic up tomorow and an after as/when i'm finnished...

if you have a really high power motor and want to get the most out of it get a ESC with programming card.

ive got a ko propo settings card and a tamiya volac MS speed controller (its made by ko propo apparently) and after a bit of fiddling you can tune the responsiveness to what your trying to do.

its quite trick if your on a tight course with only one straight as an example you can tune the power curve so it handles the power better for that track, then change it for another.

cost about 100 quid, well worth it though

hi , any ideas where i can get hold of an ESC with programming card ? ebay ? or would it have to be a model shop ?

[big.eck]

thanks for all the info/tips/advice guys . much appricated

i'm looking into up rating all the suspention and gears/shafts . as for the esc , i'm not going to fit a programeable one as i know nothing what so ever about them , so i've fount this on ebay instead

In their day they were a good motor (I have three of them myself as part of a collection of 15 or so classic Tamiya motors), but nowadays, unless you got a brand new one, the comm will be worn and need a cut, plus new brushes, the latter not being that cheap because of rarity.

Instead, £20-£25 or so will get you a more modern, more efficient Super Stock RZ that has more torque and more rpm for less current and brushes are about £2.50 a pair.

The Technigold is a lovely motor, but very disadvantaged these days.

Before either of the above though - Speed Tuned gear set.

Finally don't go mad spending £'s on the car unless you absolutely have to have that chassis. The cheapest of the modern Tamiya touring car chassis (TT-01) will kick it's arse every which way to next Tuesday. TA-02SW is a classic bit of Tamiya though for sure. Pic of one of mine below - New built and never run :

thats cracking . i broke the shell for mine a while ago but i've got a merc190e shell and a mk1 escort one now . i've just bought some alloy rear arms and alloy shockers from ebay . basicly i want a period car with some trick bits and some speed lol .

If it's used, it'll need the commutator cutting. For this, you will need a comm lathe. Your local model shop should be able to do if for you for £5-10 or so. You can buy a lathe yourself if you are serious - approx £200, but a waste unless you are running a lot or racing.

ETA: I am not trying to piss on your parade, but I don't want you spunking a load of cash on a 12 year old chassis when there's better ways of doing things for less money. I got my first Tamiya in 1986 and have had over a hundred individual Tamiyas since then - still got 60 or so. Been r/c racing since then too so reasonably qualified to comment, I hope...

Can you explain more about the commutator skimming? I have a rz540 and 959 im rebuilding, but didnt think there was much I needed to do with the motor? It never got too much use as a kid, batteries always seemed to die out too quick, and had a Bush Devil for bashing around with

heres a link to ebay for the brushes and tools to change them yourself.....

http://cgi.ebay.co.uk/Tamiya-50312-RX-540VZ-Techni...

then you'll have to find someone with a laith........good luck.....

i forgot to say , i bought an esc yesterday , it's a ansmann racing elite v/r 12t .

seems to be fine , cars alot faster now and i've swaped some of the plastic gears (from thr rear diff) to metal ones from a manta ray as they are identical lol . it's getting like scrapheap challenge in my house just now.......

it's going to be a long project so i'll get a pic up after i've cleaned it later on today.....again i can't thank you guys enough for your advice , cheers guys.......
