When I go , the servo may turn a bit of left/ right sometime.....
and sometime, turn left or right..then back to central..the servo can not back to central correct. a.bit of right or left...

is it correct? how to do check...? or set...? or should buy a new servo?

thanks :lol:lol

係因為servo輸入電壓唔穩定，最平既方法可以係接收既電源位並聯一粒1000uF以上16V既電容。接收既電源位係位於ch3既對上位置。

我都想學,有冇圖睇下?

如果你套RC只用一個sanwa 102 servo,我估你只要好似第一張相咁加一粒電容就可以穩定好多.
到於自製嗰個土炮BEC,電源係直接接在T-插7.4V上,再將個插頭插係CH3或最頂個位就OK.有約2Aoutput,一般用兩隻MG996R金屬牙servo都o.k.當然冇在店裏買嗰D 3A至10A既BEC咁好.但DIY又係另一種樂趣嘛!可以search LM7806就可以搵到線路圖,唔係好複雜,有興趣可以try try

電容可以係深水埗華輝買到，1000至4700uF都可以，16V以上就o.k.幾蚊雞左右。記住要分正負焊在線插上。希望可以幫到你啦！

this one connecting to servo, not the power??
any full set picture??.. then i can learn 1 learn...
thanks

好似第一張相咁,接收最頂個位係電源嚟.其實接收不論servo或電變位,所有紅黑線都係並聯.
