Thanks Phil,
failsafe is set at motor off.
The OS Pixie MK2 is also on my todo list, the case is printed waiting for the interiors.

Its more fun to DIY Dave, do you do Arduino stuff? If not I could send you the pre-programmed bits at cost. Is it the S/C you're interested in?
Just about to start converting a 1970 Futaba 4 channel metal case transmitter with a Digispark, that's about as much Arduino I will have experience with. Haven't had time over the last 12 months to do any modelling, with a few hospitalizations and a lot of work around the house with storm damage. I have three other conversions in various states of progress, 2 x MacGregor and an ABC Micro

Yes, I've got an OS Pixie, the earlier square case version.
Cheers,

Dave

If I'd keep one of my instruments in the shed, it would be anything but shiny and next station would be the dump, so nothing lost in my case.... :lol:
The shed is home to our 4 daily bicycles, my real bike lives inside too. :D
On topic: I've ordered some RF nanos and PA fitted NFwatchamacallits too.

No way I can use those at my club or anywhere else in the Netherlands as we're having a policy of only EU sanctioned gear or else no insurance, hence no flying.
But whenever I get to fly in the UK again it would be OK, I guess? :roll:

I've joined the NRF club. This G45 Space Commander was a true basket case and I have no idea why I decided to spend hours cleaning the case, repainting the white line on the front, polishing the aluminium plates and then having to strip, clean and rebuild the sticks when I have many other transmitters that would have made a suitable donor with little effort. The internal corrosion was that bad it had even found it's way into the battery meter so I've replaced that with a digital one I had laying around.

Anyway, I'm glad I did as it looks great and is very different. It's basic with just 4 channels, throttle lock and the single channel button.

Cheers,

Shaun

Here is the results of my lock down project. The electronics is based on Phil's project but customized to suit GG as it has progressive throttle and separate rates för rudder & elevator with no expos.
The stick is my own lock down project and has a 3rd trim/slider for whatever could be needed, i use this channel in my high rate actuators to set the desired rate.
The case is of 1mm aluminum with a few bends, and would need a paint job.
The case size is 180x125x40 mm

A few bits and pieces are still missing like On/Off switch and the push button for the timer.
Nothing of all this would have been possible w/o the inspiration and ingenuity of Phil and in part also this community so
Thank you to all of you out there

This is definitely a first Tobe. A totally home brewed RC system....love it 👍.Have you any more images of the 3D printed holder for the NRF module?

Shaun.

Here you go. You will have to "clean" the back of the board where the antenna holder is in place, I cut them flush. The tolerances are quite tight and only the tightening of the antenna will pull the board fully in place

Wonderful Tobe!

Such amazing work. I love the nRF module mount; it is so simple, tidy and functional!

two thumbs up, Werner
