Monster Beetle Steering

[Malakite]

I've had problems with the steering on my beetle in that the entire servo steering horn seems unstable and extremely loose. I glued the entire lot together as one part had snapped, yet even where the screw goes into the top of the servo doesn't appear all that firm. I've tired another Servo to see if that was the issue, but again they are second hand and I'm wondering if this means it's because they are a little worn where the tapping screw goes in? Trouble is I would need to find a brand new OLD servo (accoms) and it would need to be the larger variety as I don't know if there is a kit that would allow a smaller more modern servo to fit into the beetle - any ideas on how to solve the problem would be greatly appreciated

For now I have resulted in applying Tamiya screw lock into the servo to try and hold the whole thong together!!

The rear servo stay should be adjustable so you should be able to put in a new servo without much problem. You just can't use 2 different sized servos if you still use the MSC.

Is it an issue with the servo mount or the servo horn? If its the servo mount maybe you could try using a 3mm machine screw straight through the servo mount hole and the mounting bars (may need drillling out), with a nut on the underside, if the rear adjustable mounting bar is loose try shimming it with some very thin plastic card. If the servo horn itself is loose you could check you still have the thick plastic washer uder the screw that holds the horn on, if not find a metal or plastic replacement. Or maybe the thread inside the splined gear that you screw it into is stripped. I have 5 ORV chassis and dont have a single problem with any of them (in respect to servo issues only! lol) but the steering does take some punishment on these, as the wheels are heavy and wide they put alot of leverage on the steering servo. I regularly check it both while running and after. Hope some of this turns out helpful. Ben

Hi mate,

Pleased to say that's not a problem as I have an Electronic Speed Controller

Does anyone think I should purchase a new set of plastic sleeves for the steering servo? Anyone know what parts tree that would be?

Thanks for the insight! yes all the steering horn is complete including the plastic bearing underneath, it just seems SOOOO loose

I can't remember myself offhand but you can check the main site as the manual is there. I think it's on the K tree but I could be wrong. You could try changing out the screw that's holding it on and, failing that, change out the servo. Mine's kinda loose on both my Monster Beetle and my Subaru Brat so I was going to replace my servos and add some High Torque servo savers if replacing the screws doesn't work.

Tamiya Hi Torque servo saver, world of difference. Centre the steering servo too if using an esc.

Super thanks guys! One quick Q, do I need a specific high torque servo saver in order for it to be compatible with the Monster Beetle??

Also Vagabondstar - how have you managed to get a larger Avatar than I??!

I downsized my pic to conform as close to the requirements as I could and that's how it came out after it was approved. Maybe because your avatar is portrait and mine's landscape it just turns out bigger.

[Malakite]

DOH the whole thing has snapped now! Any ideas how I can obtain a strengthened one or at the very least an original servo saver for it??

Tamiya part number #51000

Forget the original, some of its bits are on hard to find/expensive parts trees

Brilliant, have ordered, many thanks

High Torque Servo Saver FTW!

I've just changed out my servo saver for the High Torque one and added some 4-40 threaded rods (from CRP) with Tamiya 5mm ends to secure with nuts & bolts. I highly recommend doing it. It's probably the most secure steering setup I've ever had on any of my off-roaders. Don't know why I didn't do it sooner.
