I'm just on the way out to get a couple of servo extention leads but the LHS that is open only deal with Hitec and Not JR (my radio)

are all extention leads the same???... I thought they would be but thought I might ask just in case.............

Well, it's just 3 wires, so as long as you can fit them into your servo and receiver, they will work.

Hitec Extensions work with JR, and Airtronics. They will also work with Futaba if you are willing to do a little surgery on the Futaba plugs. As MinnFlyer says, they are just three wires, so as long as you don't reverse the polarity when you plug everything in, you'll be fine.

Youll find the Hitec connections have 2 champfered edges as do the JRs, however, the Hitec's female ends also have a groove on one side to recieve a matching clet from the male end.
This clet is what ctdhle is refering to performing surgery on.
Just slice that off and youll find the rest will match up fine.

Hey flap just curious I use a lot of Hitec connectors and have not seen the tab or clet on them. Futaba does and if you want to plug a Futaba servo connector into a Hitec you have to cut off the tab or clet and bevel two of the corners. Also which connector has the + amd - power leads reversed I forget now JR or Airtronics that you have to watch out for. I intermix a lot of Futaba and Hitec servos and receivers and have modified the Futaba connectors so they fit into the Hitec connectors. (They are beginning to standardize the connectors, the newer Hitec recivers will take a Futaba servo connector withou modifing it It has the slot built into the recepicle on the reciever so it will take either Futaba type or the Hitec/JR connector)

Caution, all extensions are not created equal. Buy those with heavy duty wire (22 gauge or larger) and gold plated connectors. The cheaper tinned connectors will sooner or later cause problems. On long leads and heavy duty servos, you need the larger gauge wire to prevent IR drops from causing servo jitter.
