A cure for King Blackfoot sloppy steering!

[smallman28]

First off this method will only work if you use a ESC as where the steering servo is now mounted it leaves no room for the second one for the MSC.

First off you will need part A8 if you still have it,normally this isnt used in the course of construction.

Basically you will need to remove the current steering set up,remove the piece (and all its fittings) that fits between the front chassis rails and holds the current servo saver (piece B6) and replace it with A8 instead.

You should now be able to mount your servo in the middle,the top two holes will just about line up but the bottom two dont and you will have to drill two new holes,I found it easier to fit a nut and bolt to hold the lower servo mounting points.

I then fitted a servo saver that cost me £3 and adjusted the steering rods slightly,you wont need new ones as the set up is basically the same but it is just connected directly to the servo now.

Hope these pics help,my camera is not very good at close ups but hopefully you will get the idea.

New lower servo mounting point and servo saver.

Nut and bolts holding lower servo mounting.

Now the car can turn circles in about 4-5ft of space very easily.

Well cuffed with my efforts considering it cost me £3 to do and is such a HUGE improvement.

Good explanation there smallman28, I am planning to do this on my Monster Beetle to get rid of the offset steering, so it's nice to see that someone else has done it successfully.

I did this to the King Blackfoot I had and must say its a top mod, reduces all but a little slop.

I have left the MB as it is,I replaced the 20(?)year old servo saver with a new one and changed all the ball joints and it was a lot better than it was before.

I have already done this mod as well, only using a origional Tamiya Hi-torque servo saver and some servo-mountin parts from the Old Blackfoot. On mine the srvo has been put in place with 2 little pieces of double sided tape (didn't want to drill), which works a treat! []

You will have to be very carefull with such sharp steering though, as you will easily tip it over at speed. The long lever makes for this behavious. Stangely, it hasn't become 'nervous' in driving due to the very sensitive controll, also the standard Acoms servo seems to cope very well even with the quite big lever! [8D]

I have quite a few spare of the A8 piece so thought it was worth risking drilling it.

Also mine isnt much of a runner,run it indoors on the carpet and thats about it!

It was a runner and I thrashed it hard but I decided to tidy it up and use it maily as a display

id="quote">id="quote">I've got a replacement servo saver already, and found the steering was a bit oversensitive with the longer arm. But fortunately I've got a computerised transmitter, so I just turned down the steering sensitivity and reduced the endpoints, works a treat to stop the rolling, much easier than having to apply driver skill []

They should!

You might need to adjust the lenghts slightly but that is all.

I only used stock parts other than the servo saver and that wouldn't have make any difference.
