need electric input

[aaron1230]

any knowledge about figuring out what motor I have is and what to look for in up grading for speed
I have a RC10 with a modified Reedy motor on it now I would like to make it faster and not spend too much
so changing to brushless is probly more than I want to spend on it
what does turns have to do with speed and the KV rating and amp rating tell what?
If going brushless what combos give good speed with a single battery pack?

You need to know what esc you have and what it's rated for. The lower the turn of a motor, the faster it will spin at a given voltage. More info=more help. Google the model and make of your esc and see what it's made to handle. There's an endless amount of motors to choose from. We need to know what batteries you'll be running, type of terrain, size of tires, ect...

 

[aaron1230]

The ESC is a Tekin tsc411p - continous current 300 amp, input voltage 4-11 cells, BEC output voltage 5.7 volts, Limiter Current is 20-140 amps
The motor is a Reedy Modified Silver and Green Lable the only other info on motor is ae logo and the company address.
I have a 1800 Nihm pack and a 2000 Nihm pack from my Jato easy start use to see if RC10 still work
How do you figure out How Big of Battery can be used?
Is Lipo safe to use with brush motor?

 

[Metalhead Matt]

If you get a motor to handle the volts, stuff a 9 or 10 cell in it and let it rip.

what about turns? How many
And do motors say volt ratings on them?

 

[Metalhead Matt]

I'd stay around 15-17. 19 would be alright with high voltage. What do you do with it? Race or bash? You want a lot of top speed or a good all around performance? If your rc10 is newer, it probably came with a 17 turn motor. Stay close to that and get some good batteries. If your running a 2000 nimh, a good 8 cell 4600 tenergy would make a huge difference. Or 9 or 10 cell. I just wouldn't push it to the limit. Gets kinda tough squeezing a bunch of cells into a st. What leads you to believe your motors shot? Might just need brushes.

 

[aaron1230]

The motor runs and only batteries I've had in it is the 2000 and 1800.
I just assumed a motor would make it faster
Ok say I buy 10 c-cells is that gonna be too many volts for the motor on it?

 

[Metalhead Matt]

I don't know how many volts your motor can handle. A faster motor wouldn't get you anywhere with those weak batteries. Throw a quality 7 cell in it and you'll be way happier. Most 540 can size motors are good to 7-8 cells. I'm sure it would be fine on 7.

thanks for the advice Ill try batteries
I am used to the speed of my Jato But the RC10 is several pounds lighter so I don't think it could handle a wreck at 40 mph but if it ran half as fast it'd be a cool toy to play around with in the basement this winter and teach my nephew to drive it I was hoping to of figured the motor out in time to of took him to race it a few times and see if he could If it be something he'd like and can do (Compete). He does a pretty good job with my Jato in the drive way. I was thinking let him get a feel for electric and a crowded track and maybe...
Anyway thanks again for you help. Maybe Ill have him together for next season.

I put a full charge 2500 in the RC10 and it ran like REAL GOOD I can't wait to try a 4000 or bigger
Thanks for HELP Metal Head
Have more questions So I Know
When picking a new motor what is diffrence
in runner?
Out runner?
Can size conversion to brushless motor size?
