Reminds me of some large scale ones i make as a kid i love how small that one is

@RichiesRC - great find on the servoless model plane retract servos! I've been looking for linear actuators, but as you said, they are just to expensive. Do you have a link for the under $8.00 each ones? I looked on the Hobby King site, but can't find them.

@Wolfie - Hmmm... you made some large scale ones? Are they simple enough to make?

Yes back about 30 years ago i seen a hydralick pistin and wanted to make one that worked off a battury so i took a long treaded bar hooked one end to a motor and the other end to a baring mount cant really remember what and had some nuts on the bar for my mounts to connect to what i was moving i dont remember alot about what i did i was trying to modle the yello hydralick cillenders on a backho i do remember i had to that ram on car batt thay was 2 feet long with a trough of 1 foot and would moveabout 200 bls with no problem

maybe i should get back into making them hehehe lol

@JT Here is the hobby king link: Digital Servoless Retractable system (1pc) up to 2.5kg Sorry no buddy code with that item, they come in differant sizes as well.

links to others here: Digital Servoless Retractable system (1pc) 4.7kg out of stock.

Servoless Retractable Landing Gear Front (Steerable) 2.5kg

Servoless Retractable Landing Gear Left & Right (1pair) out of stock.

I have had those first ones on my watch list for a while and they were also out of stock but they notified my that they were back so I snapped up half a dozen , that was yesterday just before my post.

I saw a YouTube video on how to make a linear actuator from a servo but it was way to large and pretty much useless for my needs but there are heaps of videos on and about the just search "linear actuator". Ohh there is a small one inside all cd, dvd and old floppy disk drives, they have potential too.

Have you ever hurd of Muscle Wires if its small your looking for maybe this will help mondotronics.com/AboutMuscleWires.php

here is a youtube vid that discribes them

@Wolfie YesI have but hey don't have enough travel or power for what I'm after. Great product though. There is a micro servo made with the same technology and is 1 gram in weight and 38 x 9 x 3 (mm) in size, it's called "Toki BioWire 1g Micro Servo"

Can get other micro linear servos to (the type used in micro RC helis) but the Torque is only about 29.5g of Force.

I moved this thread into the Showcase category... because it is awesome

Thanks DJ

Here is the neck just about finished. The bolts are just temporary, will make some that look like the big pins that Wall-e has on most of his joints. Haven't worked out how I'm going to fit all the cables through the centre neck joint yet. The round bottom piece is hollow and the top piece will have a large hole drilled through it for the cables. I might have to have the cables come in and out at the centre joint in a cable cover.

Rich oops nearly put it together upside down.
