Which electrics for 1/8th buggy

[TommyC]

I’m looking for a motor, esc and battery for a Hobao hyper vs roller. I can get a quicrun 4274 2000kv combo for about £125. I’ve also noticed that some people pair the quicrun esc with an ezrun motor. Is there any advantage to doing this?

 

For an extra £60 I could get a max8 combo and go sensored. As I understand it they give a smoother power delivery at low speeds but not high? Is this really going to improve the experience when just bashing?

 

Looking at the overlander extreme pro 4s 5000mah 80c battery. That should do just fine shouldn’t it? What ‘C’ rating can I get away with? I understand ‘C’ x Amps needs to exceed the 150A of the esc. But would a 8000mah 20c perform just the same as a 4000mah 40c?

we use the unsensored max8 with a 2200 kv motor in our vse's , H7's and ST's

the higher the C rating means more punch and acceleration the more power the battery can give out

We tend to use 40-80C batteries with ours

I personally always preferred a higher KV 4s set up in buggy’s. For budget set ups, I ran a Quicrun 150a ESc and a cheap 2650kv black can motor.

There’s an uncensored version of the max8? Or you just use it with a sensor less motor?

yes I was going to go for the WP-8BL150 G2. I read somewhere I should be ok with a motor anywhere around 2000-3000kv. Is that right?

 

I’ll be running it 4s but inevitably will end up trying 6s in there! Does this make a difference to motor choice?

[Stormbringer]

Our max 8's are 2-3 years old now and i think they arnt sensored esc's i know the motors arnt sensored Just looked on modelsport and ours are defo not sensored

If your gonna try 6s then make sure motor is rated for 6s as it could get toasty

We run ours with a 17 tooth pinion on 4s and they go well

Quick off topic, but im going brushless with my typhon grom. Should I go more or less teeth on the pinion than the stock one?

 

The RTR 150a VS comes 6s capable with a 2000kv motor. That’s the only reason I decided on that.

[Stormbringer]

I dont know the typhon but you could try upping the pinion

keep a close eye on temps tho

Use this in my Hyper

Find it super smooth compared to previous unsensored versions I have had.

I’ve gone ahead and gone for the cheap option. Basically specced as per the 150a rtr version but cost me £150 less!
