After months of hard bashing, jumps, flips, it was finally taken out by a tiny concrete post.
I’m actually blown away by how much damage such an uneventful crash that on the surface looked like a little bump.
As I walked closer I though “oh bugger I must have broke an arm” and then almost cried when I seen it was SNAPPED IN HALF. 😑
I love this little old car, to repair or replace?
Recently swapped the stock tires on my TR10 for some much wider banded ones and whilst the grip was drastically better I noticed the motor was absolutely roasting after a hard run despite twin fans. I assume partly due to the increased load from the tires weight but also from it turning full throttle into full bonkers rather than spinning its wheels.
I couldn’t get over just how much noise the fans made for how little air was being blown out, and it got me thinking back to my PC building days and fans having a optimal spacing distance to eliminate the dead spot in the middle. Being duel fan, I also thought if there was a combination chamber it would create a higher pressure zone in the middle which would be better driven down into the fins and more smoothly exhausted.
An hour of tinkering and this was my creation. It works phenomenally well - the difference in the amount of air being forced out the fins either side seems almost double. Everything is much cooler.
The main gotcha I see though being if one fan failed you would loose pretty much all your cooling as the air would just zip out the now big empty gap, though this risk is somewhat balanced by how obnoxiously loud the fans are and how immediately obvious it would be if one stopped. 🙃
Anyone else run something similar? Or anyone want the model? I got no way of quantifying this with numbers but be interested if anyone else finds the same thing.
I printed in PETG for the final fitment as PLA wouldn’t be up to the task in direct contact with the heatsink
