i was breaking in my car engine at the parking lot and i done gone through 2 tanks at rich setting and whilst doing that i noticed i had to hold the disk break on to stop it from taking off but it would slowly creep forward with the disk brake on anyway. ok so i had done thaat no dramas so i leaned out the fuel mixture and i had the break on and my car took off with the break on so i did a big circle and tried to bring it bak to me and hopefully catch it as it went past but it didnt even get near me as it was coming towards me i turned the wrong way not used to it coming at me and i hit a pole with the front left wheel and sheered it off i got some images of where it has been broken. none of the arms or steering have been damaged just it snapped the wheel off where it is connected to the bearings where the pin goes through to hold it to the wheel can anyone tell me how i can fix this or should i just buy a replacement part?
I tried to post an image 140kb but it said it was too big and that was as small as i could get it

Also are there any tip to stop my car moving at idel? and to make the brake grip more i was thinking about a new disk and clutch but is it worth it?

It sounds like either your idle is WAY to high or your servo is not set right.The car should sit still at idle.Try adjusting your idle screw.There should be a 1mm gap when the carb is all the way in.What kind of car is it?Most cars have some sort of brake adjustment to make the brake grip more or less.

Its a Onfa Pirate off-road stadium truck with a force 15 in it. my servo is set up right i know that for sure and i cant experiment wtih my idel screw with a wheel missing can I? i was thinking could it be my clutch is engaging too soon? thanx

The clutch is engaging to soon because your idle is to high.You can try it without the wheel as long as the car isn't moving at idle you should be fine

You need to adjust your throttle linkage, throttle servo, and be sure that the throttle stop screw on the carb is not keeping the carb open. If thats the case you will have to adjust that screw so that the carb closes more. The stop screw is usually sticking out of the carb right near the air intake hole. The purpose of the screw is to keep the carb open enough to idle and so your throttle servo wont close the carb all the way when you brake.

You can adjust your idle without the wheel on there but be sure that nothing is hanging out of the assembly that will get caught on anything else if it spins a little.


As for the parts you need to just buy replacement parts, hobby grade cars always have replacement parts available. TowerHobbies.com is a great place to order your parts. Just go through the area of damage on your car and make a list of the parts you need. You should take everything apart in the area of damage and inspect everything. Pins and such should be rolled on a flat surface to make sure they are still straight.

You also mentioned that you were having problems posting a picture. There is a limit based on the size of the file, you would need a basic graphics program to crop the picture. I use various applications but Paint shop pro is a good one. There is a free trial version available on the internet on sites such as download .com

When you load a picture into one of these apps they usually have options to increase the compression of the graphic. Its usually under options when you save the file in the form of a slider bar. More compression equals less file size, you will find that as you increase the compression that the quality deteriorates somewhat. In most cases its not noticeable if you only cut it a little. Cropping is reducing the actual viewable size of the picture.

Goodluck

im downloading the trial now (55megs) i'll hopefully post some pics later the carb when fully closed is open about 2mm i just added a pic of the carb. BTW its not dirty its just the image!

heres some of the pics i croped its of the snapped part i need help to identify it so i can get a replacment part sent by post

this part connected to the other image above before it was snapped in 2. its also part that connects to the wheel

the pic above sitting where its ment to in the wheel

heres what it all connect too! note the shaft going from the left of the pic connect to the gearbox

one last pic it doenst have anything to do with the broken part just a matter of opinion do u think i should attach the wing?? i got it off my bros real robot kit cybot or something!

I finally managed to take it apart and u have a clear view of whats broken i couldnt take out the shaft that goes to the gearbox the pin was immoveable. But i would still appreciate knowing what the part is called
