I was wondering why most 1/12 scale cars I see have the solid fibreglass antenna rods with the antenna wrapped around them, instead of the flexible tubes used on TCs?

What does that mean and why for 1/12 1/10 on roads only and not TCs?

Also when I cut my speed12b body, theres a piece that looks like a flap on the rear bottom of the mould, what is it for?

Thanks for answering my questions as I'm new to 1/12.

It stops the car from sliding upside down and the fiberglass antenna can flip the car back onto its wheels.

AND the roll-over antenna is ONLY allowed in 1/12 per the rules (ROAR and, I believe, IFMAR), they are specifically banned in other classes. Hence no touring cars.

5. will add side-bite untill you reach the point of diminshing return by going too soft.
6. Slows weight transfer, will make the car less reactive
7. Whites are in general too soft, good forward bite, but lacks side bite. try yellow or grey
8. I never do this, as it really only affects the car at high speeds
9. slows longitudinal weight transfer. You don't really give up overall steering, but you will lose some turn-in
10. If you're normally running Speed 8's this body offers more grip everywhere.
11. I'd actually move the forward mounting point further forward if possible, though I haven't played with this adjustment in years.


HTH.....
Thanks

Default Chassis balancing question

I know this has been answered before but I'd like a couple more opinions. For the record, I'm only asking because my search results yielded 2 answers and I'm looking for a definitive answer

I've got an L4 and I'm getting ready install a 1s pack and the rest of the electronics. I have tinkered around with which side to mount the electronics and it seems that if I balance the entire chassis with the motor installed, I should mount the battery on the right side of the chassis and the electronics on the left. But, if I look at how weight is distributed on the chassis and with the goal in mind of adding as little weight as possible, I feel like I should mount the battery on the left (2/3's of the servo is on the right side of the chassis).

My question is: should I balance the entire car (pod and chassis) or just the chassis but with the motor wires where they would normally be? Thanks!

Balance the entire car. Be sure the T-Bar is level side to side, if possible back off the tweak screws so there is no tension to affect the balance. If you're serious about the L4 consider a 1S split pack.

You're not going to get a definitive answer because this has been discussed at length and people dissagree.

On a car like the L4, which was not designed for brushless motors, you should balance the chassis by itself. The reason is that the BL motor makes the motor box heavy on the left (non-gear) side. So if you balance the whole car you will add extra weight to the right side of the chassis to compensate. But with tires on the car and it sitting on the track that extra weight is pushing down on the right front tire more than the left. The motor pod does not come in to play because it sits level on the rear axle. I believe the disagreement may come from the fact that it makes little difference which way you do it as long as the car is not hugely out of balance.

What does make some difference is that you will have to add a lot of weight to the electronics side of the car to compensate for the battery, and the car will be quite overweight. Most of the cars these days can weigh in around the minimum so that can be a disadvantage. Like Lonny said, you should just get the excellent Speedzone 1s saddle pack. It will fit with little to no modifications and you'll have no balance issues (from the battery at least)
