Transmitter & Receiver for R5 - digital readout upgrade

I wasn't happy with the colour changing LED to tell me the voltage of the batteries in the Transmitter. So I bought a digital panel readout off eBay, the same type as I had bought for R5's dome battery level.
FS-CT6B
Testing which contacts were live for when before turning off.
The wire was actually soldered onto the end 'switch' contact.

There was just the right spot that it would look 'standard' in, so I opened up the transmitter and checked available space. Was a bit tight, but the spot was great. I unscrewed the electronics panels and moved them out of the way. Next, I marked a template up and got to drilling and cutting. I needed some sort of holder for the screws to hold the panel in place. I found the perfect piece of plastic. I cut and slotted it the allow the panel to fit into it. I drilled two holes and secured the lot with two black screws I had saved from years ago.


Once all panels were fitted back, I tested the contacts I needed and the soldered the fly leads into place.



'And the Monkey flips the switch!'

       (Name that film?)


It works, lol, it should do!

Fire Extinguisher 1.2 - 'Bad Motivator'

With most of R5 pieced back together, i've been starting to plan the extras that I want to fit into him. Now I have my Radio Controller unit, and have been re-reading forum posts on extra switch controllers, the simple 'Fire Extinguisher' project, just stepped up a notch lol.

I'd like to link a sound effect of R5's motivator blowing with the Bad Motivator popping up and 'mist' effect coming not just out the pie hole at the top, but also from around the edges of the dome, as seen in this screen grab from behind the scenes vintage footage.
Not sure I can manage the flash as well......but you never know.....
I have sketched up an idea of how it might look, but of course it has to be tried and tested.

R5's got new shoes..... (Feet motor's are fitted)

Reassembled internals on foot no1. Motor, belt, wheel, then into foot shell and locked in with the aluminium channel strip. I then fitted back onto R5's ankle.....


Ooops, I forgot that the securing ankle bolt needed to be cut short. It was that long to go through two pieces of 18mm thick wood!

Next problem I found. The gap between the side channels is slightly to wide and there (rightly so) is no flex of give in the metal channel plates. So the ankle bolt doesn't force the side channels to clamp onto the legs ankle. Again, the wood in the old internals did flex to clamp.

Lifting the body showed that the new foot is well balanced. But because the foot is not clamped I need a lock....an ankle lock. So out came the paper and pencil and traced up a wedge. Now because my foot shells are wood, the only place I can apply the wedge, in the hope it will work and not damage the shell, is on the inside face of the leg, so that the force is transferred to the metal motor frame directly below it.


And here it is, screwed in place. Let's hope this works......?

YES, it works! Well in lifting the foot and trying to tip it forward it stops it doing it.
Just have to see how well once fully operational.
And here are both new feet fitted, with there locking wedges.

R5 is (almost) fully operational - Transmitter Rc testing -1.0

Got to test out for the first time my new Transmitter this morning. Had been waiting on my mini test servo and then it was linking it all up to test which channel did what.
Picture shows ch1 linked up

 Six channels in total, two (rotary ch5 & ch6) not sure I'll need or use due to they're movement type. Ch3 is an on/off so that could be used for moving the motivator up/down......idea for the future. Ch1 will be left/right for R5's dome, ch2 forward/back and ch4 left/right.

Outer Foot No2 - New foot internal frame work 1.3

Well, due to work commitments, welder Neil's was not been able to weld up the foot frame last week, so still waiting for this to be done.

In the mean time I got on with making the angle brackets to fit the front caster onto. I cut up some U section aluminium and then cut one of the U's off, to make an L shape. Then it was just a case of marking, drilling and thread tapping holes.
Excuse the colouring in the picture, but the Sun was streaming in through the window :)

Neil got the first part of the welding done and it's a lot less cleaning up than the other one lol.

R5D4

first part of welding, done


Test fitted motor and wheel with belt back into frame......and again, there's a slight misalignment grrrrrr :( This may just be down to me and not making holes 'clearance' holes lol. Soon sorted though. Next was sorting and positioning the channel wall's, see pictures below.
Ankle bolt locked in place first to help align the two holes, then holes were drilled and tapped for the angles to support the side channel walls. Next up these and the nut to be welded.....

Electrical Board......to mount the electronics onto......eventually = 1.0

A board or 'electronics board' is needed to mount R5's electrical components onto. I found a piece of 5mm thick plywood, but then found some clear acrylic in work. So using this instead, I measured across R5's two internal vertical panels and cut it to a suitable size.

I had already cut up some 'U' section aluminium and then cut off one of the sides to
form 'L' shaped brackets. These will be screwed to the frame and then the clear panel will
be bolted ont the 'L' brackets.

electronics panel
It's that small thing just below the bolts, lol

I've also bought some servo leads, to link up the reciever to the speed controller, when I get it. And in the meantime, I also bought a servo to use as a test unit &
a power pack to run temporaly run the Radio Reciever unit
[it will eventually be powered by the Duel Foot Motor Controller]

electronics panel

R5D4 electrical
It's only on two of the angle brackets as I'm still thinking about position of the panel once batteries are installed below it. Also it can pivot at the moment, which might come in handy.

I kind of know what will go on the board, standard items are speed controllers (feet and dome), junction block, radio reciever and maybe a sound card......small steps people.....small steps lol.

Transmitter & Receiver for R5 - has arrived

It actually arrived on Tuesday, but had to wait till Wednesday
to pick it up from the Post Office Depo.

This is the same as a FlySky, but branded as a TurBORIX (?)

Outer Foot No2 - New foot internal frame work 1.2

This morning I got on with drilling and tapping holes to fit the angles onto to help locate the channel plates for welding.
Welder Dave is away, so hopefully welder Neil will be able to weld this all up tomorrow.

Build cost update 2

This link is to my post in 2011, about R5's build cost.
Build cost so far

More through necessity than real choice, I've tried to keep to a budget for building R5, lol. Since the above post, the largest cost has been the spray paint, even though I started to get the same paint as before from a UK shop called 'The Range' as their cans were almost half the price of 'B&Q' diy store prices.


So, including my recent Radio Transmitter purchase, the total build cost so far is £485.06.


Not bad really, spread out over the build years. Of course it would of been more had I of had to of bought the original wood for the frame and legs (these were off cuts from work).

I still need to buy the Speed Controllers, wires etc.....

Outer Foot No2 - New foot internal frame work 1.1

Marked up and drilled holes for motor bolts and the large hole for the motor to fit through, see below.
R5D4 motorised foot drive

Cut up two scrap pieces which will be welded across the to side plates.
R5's motorised foot drive
Fitted a location bolt to aid welder later on. Did some more work on the two channel wall pieces. Drilled the main bolt location holes and have started on the angles to support the sides for welding up.

Transmitter & Receiver for R5

Well, I won my bid for my controller, it's an FS-CT6B 2.4GHz 6CH Transmitter and Receiver off eBay (private sale) for £30 inc P&P. For now I don't need 6 channels, but if the controller does what it say's on the tin, then result! Yes I know that 'you get what you pay for', am not expecting it to perform miracles, just to do whats asked.....reliably lol.

I got this version as it had been mentioned in a post on .net about someone else needing a budget controller, yeah, same here!
I still need to save up for the Sabertooth etc, but am well on my way to that target too.
Once all wired in, I will of course write a review (good or bad the findings) :)

Outer Foot No2 - New foot internal frame work 1.0

Foot No2.
I marked and cut out a piece on the outer foot shell.


I then started on inner foot frame no2.
Metal plate, marked and cut out.

Next, to mark up the metal plate for drilling holes.

Outer Feet - New foot internal frame work 1.7

Test fitted the 'new' foot build on the leg. All fits well and looks good.
Just need to fit front caster.
Outer Foot No1 - motor installed

Fitting the front caster.
I marked up some aluminium angle and drilled 5mm dia clearance holes in it. I then tapped out two holes to M5 threads and secured the angle in place.

I didn't have to but thought it would make life easier to remove the excess metal from the
side plates, below the angle. I also have some M5 hex socket head bolts/screws
on order, as my 'supply' has now run dry ;D
