The "Foaminator"

That connector dosen't look to large, but if you want the smallest connector you could use a 4 pin Deans or the like as well.

+ and - can be run out to both servo's in parallel and then the signal for ail and flap to the remaining two pins.

Yes I mentioned 4 pins would do it in the video. But soldering is a little easier not having to join the positive and negative leads together and then to a single pin. I am not an expert at soldering, so anything I can do to make it easier I will usually do. One pin for each lead. Simple. No thinking required, lol.

I will probably make a little cover for this, just have to come up with something that can be put on and taken off repeatedly. So tape is out. Maybe small magnets.

Great idea Targetlocman. I don't have to take mine apart to get my RP to the field like a lotta guys do, but if I did, I'd definitely do something like this. Those things are a PAIN!!!

Cool, I made a nearly identical mod to my Radian Pro a few weeks ago. The difference is that I put the connector in at the wing root, and glued the wing side of the connector in place. I use a ring spreading tool to separate the connector halves. I noodled over it for days before deciding on that set-up.

Been too busy working or flying since then to post the images with a write-up. Hopefully I'll get some time soon.

I like how you used the slot to tuck in the other end of the wires.

Yeah at first I wanted to make it so when you plugged in the wing, the connection was made automatically, but in a foam construction I don't think this would hold up well over time. So I decided that since that was out of the picture, that I would take a very simple approach and just minimize the connection process as best I could.

Please post pics of your approach when you can.

Thanks odusurfer, no doubt the parkzone approach is pretty bad. If you need to remove the wings to travel or store the plane, you have to change the stock method. It's horrible. Only thing I didn't like about this plane.

Yes...all move freely. I toke it apart and lubed up the pushrods and flexed all the surfaces.

Took her out this morning. Dead calm. Perfect day.
I dropped a 2200 Rhino right in the middle of the bay and strapped it down. Flew much better today.
Did a dive test and it pulled up a little too much. Will need to move the battery back and try again, but it is better. Was much more stable in the air. I can't move the 1250 any farther forward to get it to the same point so may just go up to a 1500 or so and try that.

Dropping the flaps and flying across the field slowly towards a catch, it did seem to be much more stable at lower speeds, too. Cut the power a few feet out, pulled the nose up and grabbed the wing. Perfect.

One decently balanced flight and I am feeling the love now. Thanks for the help and suggestions guys.

I went through the same thought process... "How can I make this plug in automatically...?" In the end, I realized that the multiplex connector is far too tight. It'd eventually wear out the foam supporting it. Perhaps some day I'll add plywood reinforcement and give it a go, but this is working great already. ~3-4 minutes out of the trunk of the car, and I'm ready to fly.

I also added the Morgan Mill servo fairings during this session. I had tweaked my right aileron servo horn during my maiden, and wanted no more of that! The fairings are perfect. I recommend them to all RP pilots.

I just realized that it'd be helpful to have a better detail shot of that spreader tool... I'll snap a pic and upload it this evening if I have a chance.

One thing that troubles me about the built in connection mods is that they might work loose if the wings flex a lot in turbulence. Probably unlikely but I'm a worry wart when it comes to this plane. It's like one of the family...LOL.

No chance of that with my approach, since the cable heading into the plane has slop in it and will pull out of the fuse (an inch or so) before the connector pulls apart.

That's not really an issue if you leave one side of the connector loose. Those green multiplex connectors are crazy tight. They're not working loose with anything less than a complete wing disconnection.

If you have reasonably decent soldering skills, I really do recommend it. It greatly speeds the wing connection process, and as a bonus, you save wear and tear on your Rx servo connector headers.

I haven't had to open the belly hatch at all since the mod. Just a pair of needle nose pliers to squeeze the connector together during setup, and the ring spreader tool to pop them apart during breakdown. Quick and slick.
