Default Hobbywing EZRUN

Im running a hobbywing ezrun 35A-SL v2 speedy and a ezrun 9T 4300kv motor in my hsp buggy and was wondering what batterys you guys run with this setup and what speeds you get out of it.

2s with it, speed is according to your gearing. But overgear your motor will burnt.

5.5? It's very fast! U sure? In your manual there's a recommended gearing. Use this website www.comeseethis.com

Buggy we usually run 7.5 med track n large track 6.5. Temp of the motor should not go over 80 degree.

Are u racing or bashing n where r u from?

You will want a few 3500-5000mah 2s Lipos for the most fun, depending on how much runtime you want and how much room you have to fit the battery.

I would expect 30MPH when geared 8:1 overall, you could gear for more speed but you will have to watch your motor temperature. As long as you keep it under 175-180*F (appx.80-83*C), you can keep adding more gear to gain speed. Also adjust your start power and timing as needed to increase power, or to lower temps and raise efficiency.

8:1 will be very fast (40+MPH/63+KPH) but should be reasonable for the motor to handle without overheating, ideally I would want to start about 8.5:1 with a 6000Kv motor. Check your ESC capabilities to ensure it can handle the more powerful motor. Then get ready to crash!

Bro! 60amp ezrun can only support up to 8.5 off road.

It's better to use a charger with balancer. So ur cells are always balanced.

No, they sell a 5,5t 60A combo. It will support 6000kv/5.5t

i dont think thats a good idea, 5.5 is already very fast n your car may not able to handle it. putting 3s is like putting steroid into your car.

your spur, cvd will wear so fast, your esc n motor will overheat! if you are racing its illegal if you are bashing? be prepared to buy a new kit.
