8ight 1.0 buggy
 
Well, looks like i may be getting a 8ight 1.0 buggy race roller tomrw, and i was wonder how would it be if i ran it with the following:

CC Mamba Monster 2650kv
3s1p 5000mAh 25c or 30c pack

2650x11.1=29415

Would this push around an 8ight 1.0 on a track and compete with nitros? its almost 30k rpms

pwould be fine if you gear it correctly. I have ran a buggy with that exact setup- ran great- plenty of Go to keep up with the noise makers

any ideal on the gear i should use? Im picking this kit up tomrw

brushlessboy16 07.16.2009 09:01 PM

Gear for about 38mph. should be plenty and you can out accelerate the gas guzzlers

would a 3s1p 5000mAh 20c pack be enough? or does it need to be 25c/30c

BL_RV0 07.16.2009 11:33 PM

Since it's a 3s setup 25c would be the minimum.

Why do you say that? 5000x20=100000 / 1000= 100amps

that isnt enough? or am i missing something here?

Nope, the system is around 125-150 amps, 5k-x-25c( 30c burst )= 125amp/(Burst-150amp)

I doubt geared for 38 would pull anywhere near 125 amps continous. I say the zippy 20/30burst is fine, my .02

If you are peaking at 100-125 amps, the voltage of a pack rated for 100amps will drop = less speed.

If you get a 30c or higher rated 3s5000mah pack, you'll get 150a continuous and the batt will hold it's voltage better. Take a look at the hyperion35c thread on this forum. At 20c these packs hold 3.7v per cell.

Use the speedcalc and see how voltage drop affects your speed.

Nitrofarter ran a jammin buggy with a mmm/2650 combo on 3s 4900 rhino lipos and it worked fine. Something like 14-15min runtimes?

zeropointbug 07.17.2009 01:08 AM

Is there a reason you want to run 3s?

I have 4 x 4s1p 5000mah 25c packs for my truggy. I wanted to run the 3s packs because they are 29.99 on hobbycity for the 3s1p 5000mah 20c, you cant beat that price. then i wont have to share my truggy packs. Or i can get 3s1p 5000mah 25c packs for $43 just trying to save money is the main thing, so if 20c will work then im game, if not then ill go with the 25c packs. So will 20c do the job and not burn up anything or do i HAVE to have 25c? thanks

Sure did. Those Rhino's are 20C's as well. 14 minutes of track time before hitting the LVC.

Now I did run the 2650 on 4s as well. It was very quick but I also changed the gearing for about the same speed as 3s. I ran that with 4s 4500 30C FP's.

I have a 8ight-B now with the Tekno V3 kit. I'm running a 1515/1Y on 4s geared 14/47 and its insanely quick and cool!

Mentat 07.17.2009 01:38 AM

nitro starter, IF i go with the 20c packs what gearing should i use Spur?/Pinion? I even thought about running them in 3s2p config to get 10,000mAh out of them. Thoughts on this?
