oh my GOSH look at Piper! these pics really made me smile
#introduction I'm a retro games and software developer interested in home fabrication of electronics. I speak Z80 assembly and C
Got some drivung time with the #M05 a while ago and noticed that it was somewhat wobbly on long straightaways. It turns out that there was lots of play in the axles and steering rack. So, 28 0.1mm shims later, those parts are all tightened up!
I should probably 3D print some 0.5mm shims so I don't have to keep so many unprintably thin shims tied up in this car.
While most of the slop has been taken care of, there is still quite a bit coming from the upper suspension arms and other parts. It's a typical #Tamiya problem that haunts may of their older designs. Since I designed similar arms for my #TL01 , I might print out some tighter fitting arms for this car too.
It took like 3 days for the clear coat on these heckers to dry
The top speed is similar but the acceleration is much better, especially the low end when it's just starting to move.
I'm guessing it's mostly because the new motor is larger, but the stock motor only uses thin sheet metal brushes and they and the commutator were already pretty oxidized despite only having been run a handful of times.
The other benefit is now that the chassis has been modified, I can use faster motors. The one in there now is a 70 turn but 50, 35, and 28 turn motors are also available if I wanted to risk blowong up the smol gears in the gearbox.
