The MP777 Brushless

[virusss]

I do not know which it is mine ratio. please help me Serum the buggy is Mp777 sp2

[Serum]

speed is in km/h

the ratio of the diffs is 43/13 right? that is allready there. so all you need to do is fill in the KV of the motor, setups voltage and the used pinion and spur.

and the diameter of the tires (in mm's)

[virusss]

ok perfect thanks,fact this as I make knowing if the just relationship is? As an example my result is of 97 KMH is too much?

[Serum]

yeah, that is rather fast.

1940/8 on 6S right? with a 51/12?

[Serum]

And what is the outer diameter of the tires?

[virusss]

The motor is 1940/8 6S lipo, tire is 114mm pinio 16 spur 44, for this motor 6S is correct o too much?
Thanks

[virusss]

Dafni,for you what is the speed correct for a buggy in KMH?(Gearing pinion spur)
And the 1940/8 whit 6S is OK?

[Dafni]

On 6S, you should be able to gear for 40mph without problems. For constant running, I gear my buggy for 35-40mph (app.60kmh, maybe) But for speed runs, I think I squeezed way more out of it :017:

On the buggy I like "slower" motors and more voltage. 6S is plenty!! 5S works fine for me, too. (correct motor assumed!) Already 14Ni cells are enough for a 1/8 bug.

How many rpm/V has the 1940/8??

[virusss]

1960rpm volt but I do not know if the lehner they are load or unload

[Serum]

1960kv

[Serum]

Which is under load viruss. all the motor's of BK are rated under load.

[virusss]

My motor is a lehner no BK

[Dafni]

1960rpm/V on 6S might be a bit too much! Especially for a buggy. You will not find a small enough pinion. 5S would be better, or even 4S.

LOL! BK is Lehner!

:p
