Because you are using the same type of servos you need a reversing y harness. You can also flip the servo over on one axle.

^^ Spot on. This happened to me, so I went to the LHS and asked for a reversing y-harness. The price tag said "£10.49" so I thanked him, and got some more m3 screws. I sorted it by attaching the steering link on the rear servo to the top of the servo horn instead of the bottom. Good luck. Cheers 8-) |

Like we said... Flip one of the servos over or move your servo horn 180 degrees. | |

Sounds like the BEC on your ESC wont handle 4WS. You will need to run a receiver pack or get a better ESC... Good luck. Edit... you can buy a servo reversing Y harness with trim adjustment. I have them in my trucks. They are great. |

Mr Maxx has nailed that, I think. Your BEC rating is only 1 amp and can't handle the 2 servos amp draw. |

If you're looking for a nice reversing Y, check this one out from Expert Electronics: http://www.horizonhobby.com/Products...ProdID=EXRA325 The pot allows you to adjust steering trim on one axle. Makes setup a snap. |

OK I have a shafty 14r, with dual Airtronics 94361's . With a super rooster . Now I have no radio in that rig yet cause I am not sure what one to use. So what Radio set up would you recomend for me . :-( Cause I think that type of Y harness that JIA posted is what I need.  I have a clod based crawler and the problem I have on that is I have basic 4ws . On that rig I use a DX-3 . With a standard y harness. |

The most popular are: Novak Super Rooster - but it is discontinued Tekin Rebel II Moped There is an ESC sticky at the top of this forum. You can also run a receiver pack! |
