I am looking for a motor to replace the BadAss 2320 820Kv that weights 92 gm (3.26oz) with something about the same Kv (4S 1800mah pack) but 1/4 - 3/8oz heavier. The next size up (28xx) in the BadAss line is 3/4oz heavier. The reason for the change is I have about 5/8oz of nose weight that I want to reduce and I would rather have slightly more motor than dead noses weight. There is a Cobra motor that is hits the KV and weight, but I haven't used them and was wondering if they hold up?

I suspect that you won't have the same problem, but for slightly different reasons than Ken.  My first iteration at electric CL used a Cobra motor, which I ended up frying.

When I replaced it with a BadAss motor I immediately saw things cool down.

If you replaced a BadAss with a Cobra of the same weight and Kv, I would expect that it would run hotter.  But if you're replacing a BadAss with a bigger Cobra, and if you have plenty of cooling, then you may be OK.

Personally, I'd consider a motor that's bigger just to be bigger to be deadweight, and rather than changing an installation that works just fine, I'd just run what I have.  If you feel a need to change anything, and you're not already there, put the nose weight as far forward as you can without hanging it on the rotating assembly -- even an inch farther forward should be about 10% more leverage from the CG, meaning that you need 10% less weight to get the same effect.  Maybe sand off the nose ring and replace it with tungsten, brass, or depleted uranium.
