Firstly i've gotta thank all of you who helped me numerous times to get my temperamental buggy on the road last tuesday. Inspite of breaking it everytime i got on the track it was great fun.
I could do with some advice please from those of you in the know....
1. I knackered my pull start and have decided to get a starter box. How do i chose one? I just want one that will start the car and doesnt cost too much, will they all fit all models or are there only specific ones i can chose from? What extra do you get for spending £60 or £70 over one that costs £30?
2. I also need to get a new steering servo (many thanks again to phil for the loan). I dont think i need a super fast one but would like one that is gonna last. A few brands were mentioned on tuesday but i cant remember what they were. Any suggestions? I recall someone saying that a stronger servo would require a battery pack as opposed to the 4AAs that i'm currently using. If so any suggestions on what to get?
Your help would be appreciated so i can try and get back on the track for tuesday.
Thanks again!

Starter box is easy, go for the SMD one with a Gel pack battery. Check with Access Models they may have one in stock.
You will also need the blanking plate that goes on after you remove the pull start, again they will probably have one of those as well.
Receiver packs are around 10 quid for a NiCad and you will need a charger as well.
Not sure on the steering servo's, depends what you want to spend. The Hitec servo's are good for the cash (in the region of 40 quid) the best are generally the ACE which are in the region of £100 |

The blue SMD starter boxes seem to be the most popular the club. Get a 12volt 7ah intruder/fire alarm battery from Screwfix or an electrical wholesalers. That bettery matred with the twin motors in the box will crank any engine over nicely. A normal car battery charger set to low amps will charge the battery nicely. The cheaper starter boxes only have one motor and can struggle to turn over a new/tight engines.
If you can afford it, get the ACE/XP 1050 servo and swap it from model to model as you upgrade. They are extremely good quality and will out-live a cheaper servo many times over.
Edit
The 1st tank of running in my Hyper 7 Black, the steering servo failed which resulted in the buggy hitting a wall and breaking the weak alloy steering knuckles. Steering servo and knuckle failure is so common I'm amazed that Hobao haven't done something about it!! |

As for battery packs, i have this one http://www.modelsport.co.uk/?CallFunction=ShowSpecification&ItemID=24135
Had it when I got my Hyper 7, just cable tie it to one of the battery covers that come with the car and away you go. With AA batteries you dont get the full voltage from them like you do a 6v reciever pack ( i think you get 4.8v from 4 aa's?) so even with the standard servos youll see a noticable difference. |

yup, 12 vold alarm battery, that's what I meant...
Which ACE servo is that for £54 Pete? Sounds like a bargain?

Hi Andy,
Glad you enjoyed your first evenings racing, and yes most of us started with the same problems as you, namely engine tuning /reliablility problems, steering knuckles breaking and servos self destructing - That's why we all knew how to help!
I'm sure if you ask Lewis at Access he will get you sorted out with the relevant bits - if there's anything you've not been able to source let us know and we could probably sort out 'loaners' for Tuesday night. That's the advanatage of running similar models. |

I got an xp 1015 servo for the steering but am struggling to fit it into the tray/mount. Do i need to remove the shelf that the servos attach to and take off the top half of the servo and fit it that way? I'm a bit reluctant to start taking the servo apart unless i know it's what i should be doing.
If lewis is on here reading i think you might have given me the wrong switch to replace the factory fitted on as i'll be damned if i can work out how to plug it all together. Also any joy on the cnc knuckles? I'm still without any steering knuckles at all so any loaners or spares for sale would be good for tuesday please guys?? |

Don't take the servo apart!!!! what you might find is the hole needs opening up a little to ease the servo into, if it's the ACE it's just a little bit bigger than the cheapy you're removing.
Lewis is not usually on line so you'll have to ring him. |

Hi all
I need a bit of help please, I am keeping a watchful eye on a starter box on ebay, and im wondering if anyone could give me the best advice on which would be best to go for, 2 x 7.2v battery packs or a 12v gel cell battery, and if you say 12v, what Ah is best?
thanks in advance

not sure if it's any help Paul, but I dont think there is a great deal of difference in performance, it's generally down to the quality of the starter box.
I've always used the 12v gel packs with no issues. I assume this is an SMD box you are watching? |

Now some people might argue with this - but personally where starter boxes are concerned I would rather have Amps than Volts.
Go the 12v Gel Cell route. The Lead Acid cell will churn away for longer than two packs of Ni-mH.
As far as I have noticed, a 12v 7Ah would fit inside most of the starter boxes if you remove the plastic bits meant for the twin nicad packs. Batteries are available from Access Models, you will also require a suitable Gel cell charger, 'normal' car type charges can ruin gel cells if they don't have a current limiting feature - I speak from experience!
12 7Ah are widely available from different suppliers, just make sure it is one for cyclic use and not just a standby version - the latter fail sooner when used in high discharge applications.
If you have further problems - or would like help in fitting and wiring just ask - I've managed to fit them to both of my boxes with an external charging connection to alleviate removal for recharging. |
