In general the larger (longer and/or wider) the motor can = higher torque, higher voltage capability, and higher amperage draw. Per the specs of each:

4092 is rated up to 26v (6s)
4076 is rated up to 23v (5.5s) - not quite 6s but could run it but probably needs some good cooling.

4092 has a max draw up to 160A constant
4076 has a max draw up to 116A constant

If you have a 150-160A esc it will max out the 4076 motor before the esc reaches it's limit where the 4092 probably will max out your esc first before the motor is maxed out. Assuming the esc used won't be an issue for either motor then the 4092 will run cooler and accelerate faster when compared to the 4076 (assuming both running same gearing and volts). Acceleration is probably marginal in difference but heat wise I think it will be more noticeable.

Last obvious thing is 4076 is 76mm long vs the 4092 at 92mm long so depending on your application the 4076 is easier to fit into things like the infraction/limitless where 85mm is the longest can that fits in the stock motor mounting location.

Nothing more needs to be said...suchtragedy covered it all. 👍 get the 4092👊

Do you guys recommend the 1480kv or 1730kv? It’s going in a talion.

The 1480kv is rated slightly lower on amp draw and slightly higher for max volts so based on that I probably would go 1480kv and just go up a couple teeth pinion wise to make up for speed loss of not going with the 1730kv. However the differences are somewhat marginal so either is probably going to be just fine since both should have more than enough torque for a Talion.

If you have plans to try and go 8s for speed running then the 1480kv would be more suitable for that spec wise.

if I had to buy a nother motor, I'd probably maybe go for the 1480kv instead of my 1730 because of what suchtragedy said. You'll just have to get bigger pinions. But my 1730kv is an absolute beast and its served me quite well so far.

I mean I just bash, no speed runs. Would the 1480kv put to much stress on the talion driveline?

The 4082s are something to consider as well. Mine has noticeably more grunt than my Arrma 4074 had but isn’t nearly as heavy as the 92 length cans are...

My Talion definitely handles better after i swapped out the HS 4092 in it for a 4282 Leopard
