Medusa Afterburner V2 BL motors

[BrianG]

And the power ratings of the 70/80mm motors are more on par with what I would want for larger vehicles (8th scale); 70mm for a buggy and 80mm for a truggy/MT.

I have read only good things about medusa 60mm motors in revo's and buggy/ truggies.
I know larger can motors will have more torque, but if the 60mm motors seem to be doing well, what would the benefit be of larger cans?

I am currently building a revo which will be running 10s and a 1000-1100kv motor and a muggy on 6s which will be running 1600kv. Both cars will be geared for 40mph. Which size can would suit each car best? I was thinking 36-60-1100 for the revo and 36-70-1600 for the muggy?

Larger cans can handle more current without getting as hot due to more surface area to dissipate heat.

If it were my choice to make, I'd go 70mm in both the Revo and Muggy.

IMO. It would run cooler and more efficiently b/c it would take less energy/power to get the wheels moving literally. And you should be able to increase your run times since the motor will be more efficient.
I myself will be getting the 60-2000 (for my revo conv.) this Friday, and reading from what others have posted, I shouldnt have any issues. I may get the 70 later on if it proves to be that much of a difference.

Yeah, and it depends on gearing, and what people consider acceptable temperatures. Some people think 150*F+ is ok, but I like temps closer to 130*F max...

[suicideneil]

So 358*F is too hot? Blast those Hobbycity motors...

Im putting in a pre-order for a 36-70 2200kv, but with Mike since I have a gift voucher to spend.

Ok, so I can use a 1600kv medusa with 6s and gear for 40mph. Theoretically I can reach these speeds with all three size cans 60,70 and 80mm. I now understand the larger cans will run cooler/ more efficiently. But I don't want the truck to wheelie just by looking at the trigger. Wouldn't that be a problem with a larger can motor?

[suicideneil]

Hmm, valid arguement. The larger cans will generate more torque and therefore wheelies, but you can do cool things will esc programming to limit punch, and also alter the throttle curve so that the motor spools up a little slower, there by meanig it wont back flip from a standing start. 1600kv & 6s is a nice setup for longer runtimes and cooler temps

[jacko]

If it's being run by a MMM ESC, you could always set the punch control or the throttle curve to prevent wheelies from happening and get the benefits of a cooler running motor.

Edit: Woops. Neil just answered it hehe

well the revo is going to run 10s, so no mmm in there... but a 12s130amp esc

Wow 80mm versions . I am very happy with my 60 1600kv on 5s in my X2 CRT , would the 80mm 1100kv be the best option for a speed run car as i am probably looking at a 10s set up .

It would be awesome for a very efficient set up for sure. The 1600Kv version will be better suited for 10S speed runs.

Hey Luci , i am undecided on a 10s set up or trying my hand at the 2s record .Funny enough i just posted on your esc thread about the 200amp esc for this reason .

If i go 10s i'll look at the 80 1600kv , thanks .

All I know is you better make your vehicle bullit proof to handle all the power a 10S speed set up will put out. I ran my BPP Truggy with 10S lipos and it was strong enough to mess all my diff internal gears.

Hey, a 2S lipos speed car is always welcomed as I'm feeling kind of lonely now that Nic didn't run his 2S car .

[killermmn]

same thing kv on 80mm!!
more torque is good!!!
