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...

would it fit in a 1/10th chassis ?


any other ideas/comments welcome , thanks in advance............

Yeah it will fit but make sure your esc can deal with a 15T motor.

It refers to the number of turns of wire around the armature inside the motor. The less turns normally means bigger wire and less resistance so it draws more current and produces more power.

I assume you run the old 3 step manual speed controller? then you will find the resistor will likely to get very hot and burn out rather quickly due to the extra load on it.

You need an electronic speed controller that can handle a motor that can draw the current for a powerfull motor through it. If you look on ebay you will see speed controllers with an xxT limit (xx being variable) so if you find one with a 13T limit it means you can use any motor between 27T and 13T but you wont be able to use a 12T motor as your likely to burn the speed control out.

I wouldnt bother with the Technigold motor, certainly at that price, you can easily pick up an electronic speed controller and a new motor for not a great deal more.

If it is speed you want, then you really need an electronic speed controller as any motor with any real grunt will likely blow the manual speed controller.

You don't say what sort of budget you are looking at, but once you decide how much you want to spend, I'd look at either modelsport.co.uk, dms.com or apexmodels and give them a call as they will give you a good recomendation to suit your needs and budget - they will probably recommend a decent combo where you get a new speed controller and motor in one package. And you will get support and advice, which you may not do from an ebay vendor

If you want some other independant views, post on rcracechat.com as someone will have gone through the same upgrade path with the same car I'm sure

Regards

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.

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.

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 ?

i got mine from here

http://www.rcmart.com/catalog/rc-tamiya-42123-vola...

if your not into the whole soldiering lark this is similiar but with wires already done

http://www.rcmart.com/catalog/rc-tamiya-volac-4503...

then you need to get the programming card, ask rcmart i'm sure they have them (i got mine of ebay)

edit to add, it doesnt list a max turn motor becuase (im guessing) there is not a motor they cant run (mines 10t and it manages fine whilst going like its arse is on fire)

These are programmable, plus they are brushless too, http://www.modelsport.co.uk/?CallFunction=ShowSpec...

I'm not too up on tamiya cars but i think your car is one of the mini chassis so I don't know how it will handle the power with such a short wheelbase so i wouldn't go too mad with the power. Make sure you have some ballraces though otherwise it will melt.

thats a brush less kit with motor and esc

a thing to note about brush less is the turn is rated at double the brushed motor, so a 10.5t (as the one in the link) is equivalent to a 21t brushed motor.

its also a 1/10th car so not the mini as you suggest, ive got a 1/18th minizilla with a mambo 70k rpm brushless kit in it, its still not as fast as my tamiya 10t f103rm on flat roads

This is an old car though (and a Tamiya). I wouldnt want to be putting a hot motor or excessive speedo into it.

To be honest if you wanted to go that route I would look out on eBay for a decent chassis (associated TC5R or similar), swap that radio gear across and have a red hot toy.

ive got a ZR tuned 500g/kg torque tuned motor in my grasshopper, shreds tyres mind but no probs with it being an old car other than it not handling very good round corners.

At least in the grasshopper you dont hav any diffs to worry about.

Bet that drifts nicely, a righthandful on loose surfaces i would imagine
