Question 1

Do these plugs fit a spektrum receiver.

Accepted Answer

They DON'T fit my Spektrum AR8010T.  These aren't truly Hitec/JR.  They measure .305 inch in width.  Hitec are .297" - .300 inch.  In order to fit this receiver, you'd have to do some sanding.  I'm considering returning these because they don't work unless you modify them.  Plus the plastic box arrived with a corner shattered.  I know that's not Amazon's fault- just adds insult to injury.

Question 2

Can these plugs be swapped out with current servo plugs while keeping the original servo pins?  No crimping, just swap out the plastic plug piece.

Accepted Answer

Yes, if you take like a pin or point of a exacto knife, you can gently pry it up and the pin will slide out, and you can just slide in the new pin

Question 3

What crimping tool is needed for these connectors?

Accepted Answer

This one worked great!  Did several servos and esc’s.

Question 4

I have futaba servos. Will this kit work with them?

Accepted Answer

JR/universal standard female (the end on the servo) fits into the Futaba male with little trouble.

Futaba female needs the alignment lug cut off and usually needs corners scraped to fit in the JR/universal  male, especially on the extensions because the pin shield has no spare space.

JR/ Spektrum compatible 3rd party manufactured (Orange, Lemon...) receivers sometimes have plenty of space for the Futaba plug.

Pin spacing is the same.  Pin order is the same.

Appx 15 years ago, Airtronics changed from using a different pin order. Their old order is dangerous because the pin spacing is the same as JR/Futaba but +/- polarity reversed.  The plugs can be made to fit and the result is a burned RX circuit board plus potentially destroying every servo that is connected and it can destroy the battery or ESC used.

I have been building and  flying RC models since 1975.
