Product Information

Exacto knife, small long nose pliers and large pliers, tin cutter snips, side cutters, micro screw drivers, soldering iron and work station clamps and magnifying glass, hammer, ruler, small file set. It is hard to get it totally perfect without some accidental slight angles and or free play slop but it will still work ok . This keeps everything in central alignment otherwise you could build up a small ball of dental floss in the middle of the + cross and zap it on. Perfect attention to alignment and avoiding binding is not easy and I don't recommend it unless you are very patient and accurate.

I have a Taranis TX for flexible programming like slowing down the jerky steering movement with servo slow and or time delay and smoothing out the stop and goes. Charge-N-Go was on of the cheaper brands but there were more expensive ones you could sink a bit of money into. Grinding the splines off the output shaft will reduce the width of the servo which helps fit between narrow wheel track cars. Max]’s mobile phone is used to control the car, and a second device goes into an old phone-based VR headset to display the FPV video feed. A Vice and Dial calipers and a mini drill press would be very helpful but I have managed without them so far.

Sometimes I used a small round file to make clearance for the axil and remove the flat side of the D shape inside the hole center of the trim pot to stop the axil slightly dragging on it and moving the center position (this is not always necessary if it has clearance and you have aligned all three servo cases holes correctly with the trim pot. Briefly spin it up for a few seconds as the glue dries to check it's running true and smooth again without a big wobble.

Dremel off other internal features to create as much space as possible to house the RC components later. Now assemble with the output spline shaft only and drill through the 3 servo cases where necessary so the axil can protrude about 5-6mm each side of the servo for the wheels. Now replace the circuit board on an angle in beside the axil inside the servo and cut a hole in the lower servo case as it will be very limited for space now and need an extra 1-2mm space then tape over the lower servo case hole.

The Hot Wheels® R/C 1:64 mini cars feature the innovative Hot Wheels® R/C technology combined with the iconic decos and stylings inherent to the Hot Wheels® brand. Then you can have the throttles on each car plugged into a different channel on their receiver and use the flight mode switch to quickly change between cars for their different throttle.

thin aluminium box sections 25mm wide on most cars which is easily cut ground and shaped but some die cast models are only 23mm wide inside the body. brass sheet as space is very limited inside the cars and you need it cranked forward and I also used a smaller head screw (or grind it) to hold it on as it's usually right up near the windshield. Especially the bigger models like BMW X6 SUV (glue the doors shut) or their Chevy Silverado with a longer wheel base would both be good for someone's first attempt.I epoxy the rear servo drive motor and switch and or charge socket onto the chassis after all is tested working. Make a thin alum or brass cover for the exposed part of the servo innards and drill and grind a small slot just for the last axil gear to protrude neatly through it then use a few drops of epoxy glue to hold this cover on .

This servo hack with the 6 original gears will give a scale speed from very slow to about 25mph at a wild guess. I pushed a sharp needle (axil) through from the top to mark the inside of the bottom servo case for the hole position. Across this collection, find smaller, nippy remote control cars, perfect for drifting around furniture, navigating over obstacles, zipping through tunnels and whizzing across indoor tracks.

I found a few low quality garbage RC cars but im wanting something a bit better that I can actually drive around the living room floor and such. Most brand of servos have a similar layout and number of gears so these instructions may held hacking other brands.
