in my sc10 4x4 i have a castle mmp and i have to run the castle bec so that takes up two spots in my receiver,then i have the servo and a glitch buster...i want to plug in a fan but i need another place for it in the receiver and there are none.

yes i know a "Y" harness...but im already using one. can you over do it with added items ?

Well I can think of using a 2way splitter for the Esc and the bec. And you can purchase a 3way splitter here http://www.progressiverc.com/servo-splitter-3-way.html to connect the servo, capacitor and the fan. I have one question what receiver are you using? It sounds like you only have 2 ports... If you have a battery portyou can skip buying the 3way and use another 2way. The bec can connect to the battery port and will free up the ports.

Why are you running a BEC and a glitch buster....you only need the bec.

its a spektrum sr300


insurance ?

If the BEC won't handle it, the cap is not going to help. Get rid of it and free up a slot in your receiver.

Just looked sr300 up. You should only need 1 y harness as you can simply do this

Aux-bec
Thr-Esc
Steer-servo
Bind-glitch and fan

forgot about the transponder.

ill prolly try it with out the glitch buster.

Y-harness the bec with the transponder then.

Or like klaymon said remove the glitchbuster
