traxxas的回复是: First try putting fresh batteries in the radio and in your vehicle. Make sure the crystals in the radio and receiver are firmly plugged in. Make sure the antenna on your receiver is not cut short, and that it is all the way out the antenna tube. Make sure the antenna on the radio is up and firmly screwed in. Check the plugs in your receiver to make sure they are secure, and that none of the wires are pinched frayed or kinked. Next reset your transmitter and re-program your speed control according to the instructions in your owners manual. Here is a link that shows the procedure! If that does not fix the problem, test your motors to make sure they work. Touch the motor leads from each motor directly to the battery contacts and the motor should run full speed. If they do not, try cleaning the motors out thoroughly with motor spray or electronic cleaner spray. Oil the bushings and see if the motors work correctly If they still do not work you need to replace the motors. They are part 3975. Unplug your steering servos one at a time to see if a servo is causing the problem. If the EVX-2 speed control is the problem you will need to send it to us for repair. The repair will be $40 plus shipping. Shipping within the continental US is $5. Shipping to Canada, Alaska, Puerto Rico and Hawaii is $15.00. Shipping to international destinations other than Canada is $25.00. 从天线到接收,从马达到电调,全部要检查! 呵呵,很显然,我的情况以上都不属于. 因为我的电调不是EVX-2,而是MMM 而且无论情况怎样我需要付修理费和运费 这封邮件似乎也说明TRAXXAS对自己的产品有信心: 出了厂的,要发回去,管你有理无理,要想修就先付款和运费,呵呵 也许,经济危机使得厂家对售后失去了耐心? 既然都是付费,我就开始考虑联系好赢帮助维修 |
本帖最后由 Himalaya 于 09-9-18 12:12 编辑 解决办法,三个选择: 1) 发回CC去,然后开始死等。CC通常不做修理直接换新。注意按照CC官网的提示做,下载维修申请表,填写,打印,一起发回去。对 MMM V3 因为没有超过一年的,因而不必提供购买凭证(这一点比好盈人性)。 2) 找懂电子的朋友帮你检修,风险自担。 3) 若确系内部BEC坏了,可外挂UBEC供电继续使用。 方法:首先确认信号插头的红/黑二线(在CC是红/棕二线)内部不短路,然后照常插到接收机。在接收机的空余插槽插上UBEC输出。UBEC输入直接并联到电池端子。 |
