Default 380 motor racing.. is it? was it? a thing?

So, the TT02, DT02, Grasshopper, RM01, all.. either come with, or have options for 380 size motors. Where did this come from, is it a "thing"? I can't find it on youtube, at least not in any serious fashion.

I think it was/is a thing in Japan. See the Tamiya TA05 M-Four. It only supported a 380 motor.

It was an option used in many Tamiya kits to slow the vehicle down as a way to get youth interested and a great option. It was also something from an era when the kits included the mechanical speed controls.

The HPI Micro RS4 was quite popular for racing many years ago, using 380-sized brushed and brushless motors (then available from Novak and Castle).

They did. I should have said for 1/10 scale cars I still find it interesting that the tamiya stuff ~still~ comes with stuff for 380 motors. I was watching a youtube video.. and the top speed difference between 380 and 540 wasn't great. Acceleration was massively different... but that had me thinking. I'm not sure what yet.

With how powerful 540 motors are these days, I'm pretty sure if the same tech were applied to 380 motors they would be very effective.

I remember that my Tamiya Holiday buggy came with a 380.

The HPI Micro RS4 used a tiny 180 brushed motor as stock. There were after market motor mounts that would accept up to a 380 as well as brushless.

Heat might be an issue with a 380 motor in a 1/10th. Maybe a pan car it would be fine.

1/10th motors are around 140-145g these days.

My TAMIYA Grasshopper came with a 380 when I bought it in 1984. It has a brushless 380 now with a matching brushless esc. It is much faster but I wish it had the sensor option. (That reminds me, I should change out the white plastic bearings that my Grasshopper came with to ball bearings).

Novak had a sensored Three-80 motor a while back. I think I bought mines from Howard (for my TA05 M four) a long time ago

It's available but I don't think my Grasshopper can survive with a 8.5T

Three-80 Micro Pro BL Motor: 8.5T 9000Kv

Huh? weird. The RM01 is like.. a modern 1/12 scale car. ball, sidelinks, side damper and side springs. I hadn't expected that. And the defualt of the manual "assumes" a 380 setup.
