You want a motor weighing in at 60-90gm with a KV of 1100-1400 (around there) with an appropriate prop.
In general, the heavier the more powerful.
The higher the KV the faster.
High KV-smaller prop / lower KV-larger prop.

Both are large enough you would have to upgrade your ESC. They would be POWERFUL. Sizing down a bit would be fine like the 2826 series and still plenty of power.
Your problem is a tiny motor with TOO high a KV for a Cub with a LOT of drag. That is a small jet or delta wing motor.
Your stuff isn't getting hot because it's cheap Chinese, it's getting hot because you are using it inappropriately.
