Can you borrow a prog 4 to programme it with, or borrow a different TX, like a TX20? I have a Prog4 but it no longer works with the serial cables/Coolterm.. it's all obsolete. Nobody I know within half a days journey to borrow from ( I think you are about the nearest! :roll: ) unfortunately and it'...

Now there is a challenge for the weathering experts! A little sad, when the custodians of heritage let it rot, but I suppose there is only some much time, money, and man-hours? Phil.P All true, plus, I suspect, being basically an aircraft museum, they aren't overly bothered about an old German dies...

I'm fairly happy with the overall proportions, but I've been a bit bothered about the actual dimensions and I've juggled them around several times. I even tried to make contact with the museum to ask, but there has been no response at all, which was a bit disappointing. Anyway I think I've settled ...

It might just need a replacement Tx2 board. A c15 min job with a soldering iron.

I don't think thats the problem Rik. I replaced that last summer because I had other problems and Phil thought that might be the problem.

Is this the same for all prog4's? I was going to use mine just the other day, I had it bound up with coolterm but wasn't sure what programming I needed, in the end I was lucky and it didn't need programming. This is what I wrote back in 2022 on my Austro Daimler build thread: GTB wrote: ↑Sun, 09 Oc...

You should be able to work out the version you have, from the numbers written on the chip. Can't leave it alone, despite what I said yesterday - frustration speaking! Yesterday evening I managed to find the little leaflet that came with it originally and that says it is version 5.20. I've been thro...

Phil(lipy) You can give me a ring if you like, but it appears you are doing things correctly, but this particular receiver does not want to play? Phil.P Thanks Phil, but I've wasted enough time on this @~?%!! for something that isn't that important in the grand scheme of things, I've done little el...

Moving the direction switch to the "forward" position should increment the fashing by one flash. So, if it flashes once, clicking the direction switch forward should make it flash twice, clicking it forward again should increase it to three. Is that what you mean by "input 3"? R...

You should be able to work out the version you have, from the numbers written on the chip. I bought it brand new from Andy in Sept 2022, but there are no numbers written on the chip. I know the Rx65b had the version handwritten in gold, but this is the 41d and appears to be different in that respect.

OK, progress of sorts, I think. 1) Tx 22 in program mode, that is fine. 2) Rx 41d-22-v5 in program mode, seems to be Ok but...( I'll come back to that in a sec) 3) Tried to set it to 3,2,1,1, but not sure that it has actually accepted it. 4) Connect everything up, and motor runs fine and sound is on...

With filament you wouldn't get the same level of detail, for certain, but I'm not sure just how much you would actually lose. In due course, I'll probably upload the stl's on here, so you could try printing one of the front bonnet sides by itself and see if it works and whether you think it worth go...

Thanks Phil. I'm in S. Northants, but neither of those exhibs are an option I'm afraid, but I appreciate the thought. Now that I have an idea what I'm aiming at I'll have another play at it myself when I have a spare minute, it isn't urgent. Having looked at your 3,2,1,1 on the programming table, I ...

The resin all looks beautifully crisp. I must resume the struggle with my resin printer, if the rewards might be anything like that kind of quality! Crisp enough? :D IMG_0728.jpg The 'elephants foot' effect is due to being printed flat on the bed, but a couple of file strokes will soon sort that

Phil, Rik,
Sorry, being a bit thick now. I kind of know what you mean by "follow P1" but I don't understand what that means in practice? David T's programming instructions are difficult enough for the 65b but for the 41d they are completely impenetrable.

Is the entire thing resin printed?

Thanks guys.

Rik,
The grey is resin and the black is filament.

It's a thorny question and everybody has a different opinion! I think you've done pretty well getting 25 years from ply but I can understand your reluctance to spend £200 a sheet to replace it. Personally, I'd suggest using felt covered decking boards on a framework of treated timber and held up by ...

Thanks Phil. Yes I had already checked like that, and no sound was produced. I just put a servo on and that did nothing either. Eventually discovered that the signal wire had dropped off the Rx pcb but couldn't see it because of the heat shrink! Resoldered it and all working fine, both the servo and...

Thanks guys, that makes sense, I think. So are you saying that if I take a wire from the Ch 1 output, thats all it needs? BTW, it is currently configured that way deliberately, because I was using the inertia knob on the Tx22 re-programmed Ch 4, to control the 360deg servo which raises and lowers th...

Slowly slowly, getting there. This is the complete kit of parts, apart from the rear end face which is on the printer right now. The motor with long axles turned up from AliExpress a couple of days ago, despite them saying it would be 5th May! So the chassis is working although the wheels and motor ...
