On the other hand and in the same line of thinking, at 100HP the cost per HP of a Rotax engine ain't that bad!

I would guess that a large part of that group might solder. Soldering is more of a problem where vibration is present. I doubt there is much inside a nine pin D-sub connector with the wires being clamped down. I used some of these on my 9A years ago and have had no problems.

Let me see if I can find one a little cheaper in price than the $324 version. If I can, I will gladly buy one- then we can rent it out amongst us -12 builders for say, $30 per plane/builder? Just an idea...

RV-12Wiring
Steinair has an open barrel crimper for about $65 that works with those tiny pins.

IT seems to me like some of you are just looking for ways to add time and dollars to your project ! Are you afraid you might actually have to fly it some day?
On all my planes I just soldered the wires together with shrink wrap over it. Quick and inexpensive and never had a problem. If you ever have to disconnect it ( and I never did) just cut and redo it.

Not specific to tiny pins, but thoughts re: soldering.

Got it done!
I noticed that my regular crimper was the same width as the two tongues to be crimped so I did both crimpings in one shot. It worked. The trickiest is to strip these tiny ends and position the insulation correctly as only 1/16th of an inch need to be crimped. I'm lucky I still have good eyes at "umpty"!

small connector pins
I just bent the tabs close to the pin over with a small set of pliers and soldered. I then bent the outer tabs over the insulated part of the wire. Seems sturdy enough for me.

I've just done these using the two smallest jaws on Steinair's SAT-18 ($31) open barrel crimper as per the instructions in Section 5. I was a bit doubtful when I looked at the size of those tiny pins, but they actually worked fine.

I heard at EAA today that new kits from Van's come with these connections completed. Any truth to that?
