Csn i ise this woth my teo servos on my 4ws crawler

Um... I think I understand the question. It honestly depends on the servo and the load on it. Get an amp meter and test or find out the stall torque amp draw of your proposed servo. Voltage of battery pack is also relevant. EIR look it up.

It has 2 leads im using 6channel receiver can i use Y connector? Or i can use only one lead?help me

You can plug 1 lead into battery and y into another channel with servo or just y both battery feeds together but you lose redundancy feature

Hey guys cansomeone help me my spektrum receiver has only 6 channel and this castle pro bec it comes in 2 leads connector toreceiver can i use only 1

Use a y-harness into any channel (aileron, elevator, rudder) and have one lead for the y go to the cc bec pro. What I do to get around this is just get 7 channel receivers, but yes, you should always plug in both leads.

Is there any way to program output voltage without CastleLink?

Not to my knowledge. Fortunately, I purchased the CastleLink already for programming three 10A BEC and two ESCs before I bought the CC BEC Pro 20A for my Align 550 DFC Helicopter.
