Another Unit Crane

Nice progress dean. Is that pinion gear splined and meant to be used on a servo or is it pressed on?

its drilled out to the servo head's size minus teeth and then pressed on. Martin had a heck of a time getting it squared in the lathe and then to get it to drill without slipping.

So I would have a nice video up here for you guys but my bucket up servo has kicked the bucket. got 2 more coming. one to replace and one for backup.

Also got hobby king 6 channel radio and 2 receivers on the way. was 22$ for radio and receiver! and its 2.4 ghz

Wow that is cheap even for Hobby King. Which radio did you get? I was looking at a couple but I'm not quite sure if it's worth the $64 for the cheapy or if I'd rather go with a fancy 9ch futaba for my excavator.

Hey, Stuff, I'm intrigued by this radio. My crane's upper unit requires 5 channels, and I have a 4 and a 2 channel radio(s), but I would like to run on a single radio rather than juggling two at a time. The only other 6 channel ones I've seen are pretty expensive. Do you know the max voltage the receiver can operate on? I'm running my Hitec at 8+ volts.

their info states:

This transmitter requires a PC to modify any of the channel variables including mixing and servo reversing.

They also sell the USB cable to do the above.

What i need to know is does that have to be done to use this radio for the ESCs and servos in our cranes, or will it work already?

Do you have your radio already, and if so, what do you think of it? Dan.(pretty green at RC stuff still)

They do have more channel radios there but more money of course.

the usb cable is needed to change the radios configuration. like to change the direction of the switches etc.

as for voltage, i havent a clue. my order is on backorder because the stupid usb cable is backordered. All i can hope for is that they get in soon and get to me about the same time my replacement servo arrives. It sucks seeing the truck/trailer/crane sitting on the coffee table and not being able to play with the crane!

Rumors it works with the Turnigy 9x radio to.

4.8V min, 5v recomended, no more then 6v max according to discussion forums.

Where did you find those servos?

On Ebay. Googled around to find some strong servos then a thread came up anout these robotic 360 servos then tried ebay. Got them from ayberr or something like that. Cheap and free shipping but no warranty.

I'd look it up but I'm on my cell. Sorry!

[Stuff]

Dusted her off, put in the new radio, took it to the show. found out the wire lead for the bucket up/down is foobared...

[Stuff]

this is from the King of Obsolete and that kinda looks like a unit crane in the back ground...

[9W Monighan]

I haven't heard much of the King for a while. He used to post on the ACMOC site quite a bit 3-4yrs ago.

[Stuff]

his "new fangled" computer broke on him so he hauled out the old one.. again lol

[Stuff]

So little update to this old old thread. I got the crane out the other day, pulled that one servo that went bad and put in a new one. I have a 4 channel radio that came with my mercedes 1838 and it works well for being FM lol.

Nice little model you have. I recognize that swing gear you are using. I bought a bag of those and they seem to work pretty good. I noticed in the video that your swing is starting and stopping instantly and causing the bucket to swing from side to side. That,s okay on a small model but you would have big problems with a larger machine. Just my observation but real draglines cannot operate like that. Nice model though. Another old toy saved!!!

Good to see your back on it ,looking good

yeah swing is just a servo. would be cool to find a thing to make it work slower but it is up to the operator atm lol

Back at it for another Estevan Model Engineering Show.

Nice video, looks like you've got it running really well.

Which dragline bucket are you running on that one?

I remember you were asking a while ago, this guy has 2 sizes of boom extensions and does international shipping

Dragline bucket was an Ebay find. I believe it was 1/150th scale and its all brass.

I do need to get those extensions. Originally that guy would not ship to Canada he was quite strict about that.

I would like to find a bigger scale looking bucket but all I find is 3-400$ ones that are models!
