cheers for advice on sunday guys even though it was a short visit for me due to overindulgence the night before i needed the morning to recover from hangover. just a few questions which are pretty basic to you lot but im still trying to get my head round
1. with a 17.5 brushless how do i work out what pinion gear to use? or is it dependant on track? if so what would you advice?
2. i noticed most of you run solid rims . is this for a reason? i dont like the fancy 'tamiya toy' ones but ive seen some fast trax saloon wheels which are pretty basic but have holes in them so can i run these?
3. am i right in saying sorex 32r tyres are the ones to run normally? also do you suggest foam inserts?
4. i guess weight distibution is quite important , is it worth investing in 4 x cheap scales to do this and use car rim weights to balance car
apologys if your thinking , great another new guy with lots of questions , i learn fast though.

These days most people use pre mounted tyres which come with a solid wheel and medium insert, so no need to think about that.
Re 4 scales, I do this and it's a nightmare. Don't! Just balance side to side front to rear, make sure it's 1500g and get on and race.
The biggest thing is driving, a lot of stuff isn't that important until you can drive without mistakes.
Were racing indoors tonight if you want to see more!

I was running 28's sunday, they were the first tyre i started with... I found them very cost effective for performance Vs length of life for the speeds I was doing. run solid white rims are common because they come pre-glued with most tyres.... and gluing tyres is something you dont want to worry about just yet. A set of pre-glued wheels are much easier and possibly more cost effective??? buy them - bolt them on - away you go |

personal opinion is no...
stick to Nosram, as they have great support in the UK - the "club shop" reality racing deals in a larger selection of their products...
Come and have a look at aldershot this weekend, and see what people are running, if it's not blue or red, it's not in the hot cars in general...
Also on a point of interest, the Nosram ISTC has a rating of 400A per phase, total of 1200A even if that speedo you quoted has 70A per phase total of 210A that's a huge deficit...

Post by mattsedgley on Apr 15, 2009 23:06:59 GMT
nope...
like i said Nosram ISTC or LRP sphere, you really need to come down to the club and have a go.. and have a look at what every one is running....

i dont fancy paying £200+ for an esc tbh , if the skys the limit then maybe , but i start buy stuff at that spec and ill be skint before weeks over , agreed they are the best and in the ideal world i would , but i gotta be realistic lol. btw from what i read , 400a per phase and 1200a is ridiculous amount , if i was running a super powerful motor then yes but stock motors wont even scratch that tbh |

In my opinion for £60 or £70 I'm sure the Orion Vortex speedo would cope admirably with a 17.5 motor. It'll get you racing, and probably last you for many months before you thought that it was the speedo limiting your performance, rather than something like car setup or driver ability.
High-end speedos are popular because they perform very well, and for a good while there was very little other option than a high end brushless speedo.
But now with brushless becoming the norm, there are many many low priced brushless speed controls coming onto the market, many of which I'm sure are fine for beginners and club racers.
One thing to consider with electronics is warranty backup. If you're not a risk taker, make sure you can get good backup and send it back if it goes pop, cos electronics do go pop, and if you don't want to shoulder the cost of failures yourself, then buy in the uk, locally preferably, with good UK distributor support.
(On the other hand, if you're a risk taker like me then you'll buy electronics from the other side of the world and just lump it when they break!)

Simon and Matt are both right in their veiws...the ESC is the fuel injection system for the Motor and you get what you pay for,if youare happy to "bumble" around the track while you are learning and perhaps get out performed slightly then go for the cheeper end of the market?.
But if the bug bites and like many in the club you become compedative in a very short time you may wonder why you spent £60 on a cheep'ie ...personaly I would go for a midle range ESC(£130) and aviod the cheep and nastys like the plauge!!!.. some of the midle range ESC's may not have a well known branded name but can be just as good!...cheep'ie ESC's can feel like a on off switch to drive,not at all smooth.
Ps I would also strongly advise against a used (E Bay) ESC too....one from a club member that you can try or at least see running is a different mater.

Nobody has mentioned I think but a newbie will regret not buying an ESC with reverse |

Nobody has mentioned I think but a newbie will regret not buying an ESC with reverse Sorry Pete but I dissagree with that one chap reverse may be handy for indoor racing with mini's ,but for TC's out doors???,plus if a chhep'ie has reverse too I bet the forward function is very cheep and nasty..At least spend £60 to go foward as smooth as poss ....plus reversing back onto the track if you are learning could spell disaster for other racers  |

Sorry Les couldnt agree less on this one. You are at the track on Saturday practicing. Drive into the tyre (e.g) So you have to come down off the rostrum, walk across the grass etc etc. As a newbie doing that nearly every lap you will give up the sport rapidly.

I would agree with Les on this stick to a forward only speedo without doubt.
I would however consider a speed passion GT as a cheaper alternative, very smooth on acceleration and very easy to program with the set up box supplied. Try to aim for a middle of the road priced speedo if you can afford it.

So would the guys the nooobie reversed into during the heat of battle while racing or free practice,a bad habit to get into....learn to drive,come off or get stuck to often you will soon learn...lol...it takes skill and full awearness to reverse safely Reverse back onto the track at certain meets and cause a pile up..you will get black flaged!! thats why reverse is banned |

it's a great speedo.. Simon Crabb is racing with one of those now.. he's one of the quicker ones in 17.5
like i said.. if it's not blue or red, its not used much!

so i can afford a better esc im gonna only get 1xlipo 4900mah traxpower for the moment. that frees up the cash for the more expensive esc , im trying to stick to a certian amount as if you dont set a limit you get carried away! |

Les I can see where you are coming from but look.
A newbie spins in a race. Does he wait for the cars to pass before spinning around and going again, or does he ignore the cars and do it anyway and take two of them out.
Take the A final last Sunday, a certain driver took Mark out when Mark was lapping him and nearly took Craig out in two finals (made contact) when Craig was lapping him.
Your point is perfectly valid but is all to do with the sensibility of the driver and the recognition of etiquette and/or rules.
You will appreciate that my point was addressing learning and practice not racing – not needed in racing due to marshals, although I accept the fact that if you have reverse, the presence of a marshal doesn’t stop one using it with disregard for other drivers.
You can of course now buy speedos with reverse which can be switched off but they are probably more expensive and defeat the point for a newbie trying to keep initial costs down.
Having brought 2 juniors into the sport and having spent many hours at the track with them practicing I can only say that reverse was manna from heaven and I would recommend it wholeheartedly to a newbie. Indeed if I had a shop, like Terry I would sell them to beginners too.
I doubt a newbie would outrun a half decent speedo with reverse in his first 2 years let alone his first year.
As Browne and Cameron said, we will have to agree to differ ;D

Ide suggest looking at the Losi or Speed passion Low profile one. Decent price for performance and features. But definitely try and find reviews / opinions from people who use these.... I myself use a Sphere TC (but mine was over-shore at $200 when the exchange rate was 1.95:1) So even I may think twice about £200 for a esc now.... especially if you haven't really tried the hobby.

A car that spins out in front of you gives you a visual warning to slow down and avoid it as best as poss ,but a car that is stationary and sudenly carears backwards at you is a bloody nightmare..fancy flying down the strait with our brand new 009 and a racer that has poked his nose on the grass sudenly give's it a fist full of reverse...ouch big expence,at least the car that "spins out" and takes you out is probably going the same'ish direction....for me and others, reversing on the track is a NO NO..having reverse is a big temptation to use it in the heat of battle and do some serious damage to another car. Matt,Adam,Reubs have all "grown out" of cheep gear in the mater of a few months.  |

I wouldn't classify £65 as cheap Les but all our wallets are relative I would! they just dont perform, whats Craig using I bet it aint a 65 quider .....as for reverse,all due respects Pete you need to race to understand....you just cant react to some one who uses it just in front of you. |
