The medusa is a stout little motor and I think in 70-80 degree weather it would be fine, it just heats up to high to my liking (160-170). I just don't like to stress systems unnecessarily. The main reason I bought it is because I thought the tekno neus would take longer to come out and I didn't want to wait for the CC motor.
I do think the medusa would be perfect for a 1/8th buggy though.........
Which means I will keep it for future needs that could spring up.
