I have built a few tc3's in the past couple of months. I found a couple screws in each kit that had threads that weren't sharp. In fact, if you were to mic the threads, the threads were a couple thousandths smaller. Pull out the screws that don't fit tight and compare them to ones that fit tight. look very closely to the sharp edges of the threads. If the problem is stripped holes, you can buy a 4-40 heli-coil kit for about 39 bucks at a local hardware store. These work great and you should never have any problems again.

Can you get a two speed tranny for a Elec TC3? I know there illegal for racing but just for kicking around .

JAHAYA.

When the screws on my son's TC3 started to get sloppy I simply replaced them all with 3mm metric ones. No drilling or tapping required. Just a tighter fit.

We haven't had any more trouble, and in Europe metric screws are more readily available. I got mine from Titanium Racing.

The black graphite drive shaft has beed discontinued and no longer available. The new AE aluminum one is more durable and cost around $6.00. The down side is that they will bend.

looks like the new factory team shaft is made of aluminum and about 35% smaller in diameter then the IRS shaft i had. and its a third the price!

the part number is listed on this post somewhere! mine will be here next week for $8

superk -

Aluminum Driveshaft:
Depending on which one you get it (Associated ,IRS, etc) can be almost 2x as heavy as the graphite one.

The aluminum unit will be stiffer and make the car more responsive (torque-ier) because it wont flex as much.

Increase drivetrain efficiency as more power can be transfered the the wheels without much loss due to flex.

If it bends, it will stay bend.


Graphite shaft:
Lighter but more flexible.

Will allow a faster spool up, but its flexibiltiy will make acceleration appear to be soft.

It it bends, it flexes but returns to its original shape.


Keep in mind that an increase in rotational mass is equal to increasing sprung weight threefold.

For example: say the stock shaft weighs 1 oz. The aluminum shaft weighs 2oz. Under rotation that 1oz difference actually becomes more like 3oz. Those 3 oz will increase the weight of the car.

In the end its a trade off - light and flexy, with a faster spool up or efficient but heavier.

ZERSHNL - Good thoughts.

Finally-a couple (dark) pictures of my milled chassis'. Notice that the battery box has been milled dwon and slots are added.

This picture is from the bottom. Notice extra lightening holes under the tranny cases and the bigger opening under motor.
