Track Studding.                                           There are many variations of studding, this example is a good one for the stock track supplied in your kit. The suds are No. 4 self tapping screws, phillips pan head, 3/8 “ long. Due to the clearance in your drive sprocket and the rear side Idlers the screws need to be placed 1/2 inch from the edge, minor adjusting may need to be made, since there are many variations of drive sprockets.

Here are some examples of machined drive sprockets. As you can see depending on which one you have you may need to alternate your studs. Balance is always a must, an uneven studding patter will affect the way it steers

Clutch Overheating

Clutch shoes should be machined to allow the spring to seat lower, thus allowing more life to your clutch system. If the Spring hits the inner clutch bell it will over heat and needs to be replaced.

Belt Jumping off the track

Clutch Overheating

A standard kit includes 2 washers to attach your clutch bell to the engine, these must be replaced as they wear, these flanged replacements are available now, also see Colas hobbies for their Upgrade.

Hard Drive System

Due to packaging, the track belts retains an oval shape, using a heat gun, warm the smaller radius until the belt regains a full circle shape. Also check the thin portion of the track, if its more than.100, its too thick, have it replaced.

There are many reasons that may make the belt jump from the track. Here is the main one. As you insert the rear suspension, check to make sure that there is .005 to .0010 clearance on each side of the belt to clear the rear Idlers. If this area is too tight make sure you have inserted the bearing all the way into the rear side Idlers. If they are you may need to shave the sides of the belt until you have proper clearance. there is a .020 tolerance on the belt. If this is not followed it will cause the track to jump.

Shock Trouble

Have you build a shock and it doesn’t return when pressurized. Here’s the little culprit. The flash around the hole on this piece is keeping it tight against the shaft. Remove it with a knife and your trouble will go away.

Protect Your Sled

Always keep a bottle of Rain-X s pray on hand, Spray throughly under the track and suspension when assembly is complete, and let dry. Use once again prior to use. Always keep your suspension free of build up.

Antenna position

You must keep your antenna away from the electronics and as high as you can. With this set up you should be in control up to 120 yards.  Electric Art Attack should keep the antenna in the rear of the sled away from receiver and speed controller.
