Servo strengthener. Make a 7980 twice as strong!

[Erik D_lux]

Servo strengthener used to make your HS 7980 twice as strong.

One purchase will do one servo.

You will need to program your servo so it has 180* of throw. I can do this for you if you send me your servo.

This mod makes your servo 2x as strong and also 2x as slow.

Universal application, you may need to modify to fit your specifc application.

I am not planning on sending the 4 screws that hold the servo plate to the servo mount. Since there are so many different types of mounts, there will also be a need for different length screws for each. For example, on my Delrin mounts, I used the longest possible screw to make it as strong as possible. If youre using a 1/16" thick AL servo mount, you will want a much shorter screw. If a common length screw can be figured out in the future, I would be glad to supply them.

Comes with 3 different length arms to get the perfect amount of throw and strength.

You will need to buy the gears seperatly from Servo City, 48t hub, 24t servo gear. Plates are only for 2:1 ratio:

32 Pitch Aluminum Hub Gears (1/2" Bore)

32P Hitec Metal Gear

WTF! That is pretty cool. Always innovating over there at the Dlux shop.

Install should take about 5 min to put the parts on the servo. You will want to pay extra special attention to your geometry and get everything perfect including the drag link length.

To install:

Install the brass servo gear onto the servo output

Install CF plate onto the servo using the 3 aluminum spacers between the CF plate and servo ears. You will also want to loosely put the larger screw into the slot. Tighten the 3 screws lightly so you can still move the larger screw in the slot.

Slide the aluminum sleeve onto the larger screw with the flange down.

Slide one bearing onto the aluminum sleeve with the flange side DOWN, install the supplied shim on top of this bearing

Install the steering arm on TOP of the aluminum hub gear. You may need to do a quick grinding on the CF so it does not bind on the top bearings flange. If you do, just take a very, very, very small amount away. If you take too much, you will compromise the strength of the two holes that hold the CF arm to the aluminum hub.

Slide the large aluminum hub gear over the bearing you just put on

Slide the 2nd bearing over the aluminum hub gear with the flange side DOWN

Install the nut on the large screw and tighten when you have a good tight mesh (by sliding the whole assembly closer to the output gear). Make sure the aluminum sleeve does not come above the top bearing. The nut needs to tighten against the bearing, not the sleeve. The first couple sets sent out will most likely need to be shaved. You can do this with something as simple as a dremel.

Finish tightening the 3 screws that hold the servo down.




As said above, you will want to make sure your geometry is proper. This means nice straight lines and you do not want your steering to cam over when steering away from the servo. If you have larger angles going from the steering arm to the knuckle or if your drag link cams over at full throw, it can stress the CF plate and ruin your mesh causing problems.

The best way I have found to make it so the steering does not cam over is to set everything up so that when steering towards the servo that the rod end will touch the CF plate at full throw. If you do this and it still cams over on the other end, you need to step up to the next larger steering arm until it does not cam over.

Below is a picture showing that the servo bottoms out just barely hitting the CF plate when it swings towards the servo side.




If you take a look at this picture, this is they type of straight lines we are looking for



Something like this with a large angle drag link will NOT work

Thanks man!

It makes a WORLD of difference.

I'm IN Great products as usual Erik!

Any plans on making one that fits standard size servos? Or will this one fit a 7954 already?

[Erik D_lux]

I have thought about it but I have not pulled the trigger just yet as I didnt know of an application that could use it. The only RC cars that I really know well are 2.2 MOA and Supers. I know on my 2.2 MOA, I dont need this and it also would not fit, I personally would step up to a 7980 first. Fitting was also a concern for other applications.

If there is a demand for this in the standard size servos, speak up and I can make it happen.

Here is a video showing the strength increase before/after

Any Scaler guys out there?

I just had a thought.... is a bad ass winch in demand? Seems like this mod on a 7980 converted to a winch would be brutal?

[Shinjari]

Super winch would be super =)

This is what the hub gear looks like in stock form ( I cut mine to remove bulk in the above pictures)

32 Pitch Aluminum Hub Gears (1/2" Bore)

I have never really looked into what it needs to make a winch work but it looks like you could simply bolt a spool onto the hub gear and youre good to go?

[Erin]

Turn a spool and make it a set ;)

Most spools out there might be difficult to tap into because sidewalls are pretty thin

[Erik D_lux]

Got a link to a spool that is commonly used?

If you cant tell, other than knowing that you guys use servos for winches, thats about as much as I know about them.

As far as the idea goes, would this be pretty cool, way cool or a much needed product?

I'm pretty sure that setup would fold a scaler in half I'm about to mod a 7980 into a winch, I'll let you know if it needs more power.

I really like the size of the mad dog rc spool. Holds alot of line.

True, but it might turn a 645 into a beast without breaking the bank

[Erik D_lux]

I forgot to mention something and hopefully it does not throw a wrench in anybodies plans...

I am not planning on sending the 4 screws that hold the servo plate to the servo mount. Since there are so many different types of mounts, there will also be a need for different length screws for each. For example, on my Delrin mounts, I used the longest possible screw to make it as strong as possible. If youre using a 1/16" thick AL servo mount, you will want a much shorter screw.

[Illeagle]

Erik how much height does it add to the servo? Do you have a closer side view pic?

A 645 operating at 1/2 speed would take a loooong time to run line wouldn't it? I think it would make a good winch for the 1/6 scale guys though.

Very true, but I run them at 9-12v, so it should be to bad. Erik is gona try and figure out the gear to spool ratios and see what it looks like.
