Radio Control 2

Ok, cut down variables, ordered FlySky FS-i4 4 channel transmitter, I had 1 but gave to my dad for controlling his speed boats, I have a few FlySky 6 and 4 channel receivers that will work with it.

I'm concerned that AAA batteries are not good enough to drive the buggy, so I've ordered some Lipo batteries and a multi-charger.

I've added level changer to the controller PCB, made the PCB then discovered I have no PCB drills left, tried a lesser quality drill and messed up the PCB, so I've ordered some more.

Whilst awaiting, I now have lots of very small parts, M1.6 washers and nuts, M2 washers and nuts etc. I have no place to keep such tiny components, so I'm creating a modular clip together drawer set.
Clip together is not an easy concept to make work in 3D printing.

Lipo batteries arrived, multi-charger has 1 type of connector, batteries have another!!!!
Ordered some leads of each type, will make up patch leads when they arrive, but for now I can't use the batteries (sigh).

Transmitter arrived :-)
Put into Trix controller, it now appears to work perfectly on desk. I can build up the complete model, test it, get to know it, then switch to my controller and compare. Still lots of fiddling, I now need to put back all the deck hardware, set it all up, float it to get water line, paint bottom red up to water line.

Put receiver into Buggy, not so good, it works perfectly off load (lifted off floor). It won't drive for long even on a flat smooth level floor. The cogs bind, probably too much play. I'll probably redesign to use worm gear drive. Again, once I get it working with standard transmitter / receiver then I can play, get to know it then switch over to my controller. Cut out all the variables.

Basically, all on-going, nothing completed yet. 

I forgot how much smaller my controller is than a standard receiver, that was pleasant.
