hi i im new to rc's. like a speed loving freak i just bought the sprint 2 flux and i was wonder what upgrade i will need to get and what other i will need to make the performance better.

You can get the list f hop ups from the manual or from the HPI website. I think one for sure would be the universals or cvd's.

whats the difference between running 48 pitch and 64 pitch??? I know the physical difference, bur what is the performance difference?
Thanks guys

64p is quieter and more efficient

I was thinking about picking one of these up. Any good for VTA racing with 21.5 bl ?

i have a sprint with MM 6900 and i want to know, do you guys think that i could put a 3 cell lipo in the sprint? could it handle it? I already have aluminum pulleys and the metal spur gear holder, the rest is stock. Anything else i would need to run lipo?

Willystylz

I don't think your 6900k could handle 3S. 5700k is barely able to. On 3S it is likely your motor will quickly overheat.

if it makes a difference, im only going to run it in the winter because im busy other times, so around 40 degree weather anyways. and im going to fit a fan on the motor sometime later as well.

Willystylz

As long as the motor holds up at such a high rpm, try at your own risk. Why do you need all that speed? 6900k on 2S lipo should already be faster than greased lightning!

My Feedback: (1)

Lol thanks mate. Is 3S really that much? Would 2 cell be much worse than 3?

Willystylz

Well 3S gives you about 33% more voltage (11.1v vs 8.4). But geared right, your 6900 on a 2S would scream. The stock Flux uses a 5700kv and i know it can do about 45-50mph on a 2S lipo. On your 6900 it'd be pushin 60+

Now that's what I'm talking about, ill probably get a 2s then since its my first lipo

i have a sprint 2 flux and when i drive it on roads i can never seem to make it goes straight...i keep playing with the trim but it still cant seem to go straight when it picks up speed. i check all of the turn buckles and stuff and it doesnt move much.....how can i fix this problum???

Yongbum219,

It sounds like there is still slop somewhere in your steering. My flux runs like it is on rails, even at high speeds. I would start with the servo and work your way to the wheels. more than likely it is the servo saver, or the servo itself...if everything else seems tight.

yongbum219

i have a stock servo and i put thread lock on my servo saver....

Willystylz

check your toe-in & out, maybe one of your wheels isn't adjusted properly causing it to pull to one side?

MD6

Make sure there's nothing hanging up one of the diff's. I have a friend with a Sprint 2 and it came from the factory with a screw that was too long near the rear diff hanging it up at times. I have seen other problems from the factory. These are the problems I have see: a missing "e' or "c" clip in the steering rack, a missing spacer in the steering rack, and a missing bearing on the shaft that the spur spins.

Willystylz

In my goody package last night I got two sets of Hot Bodies aluminum shocks. Gots them all assembled and installed last night. Gonna throw up some pics tonight. Just to let you guys know, these are smooth as butter and night and day difference compared to the plastic shocks that are half-hazardly filled with shock oil.

iMOD

whats a good way to do this with nooo tools if possible?

iMOD

your saying its during acceleration? what about at a constant speed?

Willystylz

I don't have any fancy setup tools either. All I have are my eyes and trial and error. One of my Sprints had a pulling to the side problem straight from factory. Had to make the proper adjustments and is good to go now.

iMOD

yeah after i installed my RPM ballcups, i used my eye, and i have slight toe in. however by looking at the spaces and threads in the tie rodes, i can see one side has les toe, but compensated with more camber,, bringing the wheels straight. should i fix this?
