I think the 80mm is a bit overkill. That and you may want to go up to a MMM, not sure how much more power the 80mm will produce. I am figuring the 80 amp model can handle a 7xl (rcm mike has this) so it should do the 70mm motor with reasonable gearing. The 80 mm may have too much torque and blow the tires off too easily and the startup current draw will be more.

Alright well since I only want to do this once... what about a MMM esc, 5s, and a 80mm? I am just thinking for $20 more, i could get a better setup that would run cooler and be funner to drive. Well now i am all confused... I want the setup to run cool, and i don't want it to be putting my esc in jeopardy.

What are you looking at spending on the motor and esc?

If it is more than $240 pm me and I will pass along some info...

Over $240 might work... p.m. sent.

i either want a 4s setup or a 5s. I just need to price the two... it's hard because i want to run the 70mm on 4s, but then the esc becomes the weak link...

The MMM is a better esc than the hw80, it is more like a MM. If you plan to push some power having a better esc is always a good thing...

I wouldn't bother with the 80mm in a Hyper. I've got a 70mm 2000KV in my street Hyper 7 TQ and with an 18T pinion gear temps on the motor and ESC (MGM 16018) are just a little warmer than ambient.
