圓規效應
中心係車尾
外圍係車頭
基本上如果車尾唔行咁車頭轉灣
係可以原地掉頭

點樣鎖住對後碌?

鎖一個后碌仲好玩

Info from www.rc411.com

1. Locked Turn
The most commonly used locked dig is the turn. Locking the rear axle and steering the front wheels to full lock will allow the crawler to pivot. Almost a perfect rotation can be achieved. Making a sharp pivot-like turn allows a driver to reduce the amount of reverses needed to line up for a gate. Each back-up costs a driver one point. Those points can quickly add up. Jake says that this feature alone is worth installing dig in your crawler, as competitions are often won by just a few points

2. Locked Descent
Jake says the other use of locked dig is during steep descents and drop offs. Locking the rear allows a crawler to slow a descent by dragging its rear down a steep slope. Slower is often better in crawling as it allows the tires to maintain traction instead of bouncing down the grade, risking a flip or rollover which will cost the driver five points. Jake says that you need to be ready to throttle out if the rear loses grip and tries to swap ends with the front.

3. Locked Climb
Jake says that sometimes he likes to lock the rear when getting ready to attempt a steep climb. Doing this allows the front tires to bite harder and wrap up on the wheels. Jake then quickly pops back into four wheel drive and uses the resulting spring to give him a little boost up a difficult slope.

so thats mean require 3 channel....?
and no more gun transmiter ??

基本上即係原理上，但實際上梗係唔得啦。
我係想講個比喻話個dig係咭住堂尾，咁轉起上迷好似個圓規咁上下。

RCMart !?
