The savage is also much heavier than your performance truggys and yet you are all having problems...
I bought a neu 1520 motor thinking that this torquey motor should be able to handle this gearing as it would be much more efficient... yet people are telling me that its over geared even though HPI sell these stock with this gearing....

Thing is, the stock flux is lighter than your custom flux, and it comes with a 1515 2200kv motor; on 6s lipo with stock gearing 55-60mph is about top speed roughly, and even then thats an on-road kind of setup, 60mph offoad would be pretty much uncontrollable over about 50% throttle. Your truck is running a larger, more powerful motor yes, but its a much lower kv, and the voltage is the same, so gearing it for
higher speeds than the stock flux places a much larger strain on all the electronics, hence the high temps. The 1520 and 1717 are great motors for heavier weight vehicles running the same speed as lighter vehicles that use higher kv motors. For example, my 1518 1800kv motor ran nice and cool on 5s lipo in my 13.5lb TXT-1, but my 1515 ( ish) sized medusa 2000kv motor runs somewhat hotter in my 13lb Gorillamaxx on 5s lipo too. The Gmaxx is geared for 40mph, the TXT-1 for ~35mph- if I wanted to run either truck faster I'd go for 6s & a 1518, and aim for about 50-55mph tops- keeping my speeds and expectations realistic...
Knowing whats realistic and why comes with time, and lots of research/reading around to learn from other's experience. That said, you're in the right place for certain; Rc-Monster is known as 'The Encyclopedia Brushless'
