Any good website for 9e upgrade parts?
Now i got to start order battery.

Anyone ever try running on 3s?
In term of speed is it meaning to say 4s run faster than 3s with same pinion?

Hope can get some info from good bros here.

Cheers

More power = more speed. Thus 4s will be better than 3s and will allow the motor to run under less stress and lower temps. Too low cell count will drain the battery very fast and thus its lifespan will shorten as well.
9e parts can get from Winnie.
Batteries can order from Hobbycity.

There is a "B" version, but it's not available in the states. You can buy the parts to convert from ebay. Most of the parts come from Asia anyway.

Nitrohouse and Ebay

Now i got to start order battery.

Most of the batteries come from China, so you should have no problem finding good cheap batteries.

The more cells you run the better the efficiency. You adjust the overall speed of the car with a lower KV motor with the higher cell counts. Example:

3s + 2650KV + 14T pinion = 38.5mph
4s + 2100KV + 15T pinion = 37.7mph
5s + 1700KV + 13T pinion = 38.2mph
6s + 1300KV + 14T pinion = 37.7mph

I wonder why they include a 14T pinion with the kit?...


Hope can get some info from good bros here.

Cheers
I hope this helps.

Thanks for the info. It looks like the City Blocks and I-Beams are the tire of choice at the outdoor track that I will be racing at. The Crimefighters tread looks to be taller (beefier)...is that correct? Are the Crimefighters going to perform differently, compared to the City Blocks and I-Beams?

Also, keep in mind the the cost of the battery is more related to the capacity than the cell count, and the higher cell count setups don't require as much capacity. Therefore, not only are the higher cell count setups more efficient, they also cost less.

Now if we could only get ROAR to follow this line of thinking...

And comes with a bearing too, yes this design was well thought out. Thank you again, Brandon Wong.
Your very welcome, I'm glad I could help.. please give me your feedback once you have everything installed.. oh by the way I included a flanged bearing which is to replace the bearing on the center diff, it's self explanitory but if you get stuck just call or email me..

Sorry Shano, I tend to make one off prototypes for myself and do testing with it.. but maybe in the near future I would make more parts besides my mounts.. but for now maybe SNR could help you..

Thank you for the compliment SNR

I have figured out why the doggones bend so easily on the Hyper 9E!
When using the stock shock oil which roughly = 27.5wt of Losi
the arm allows the doggone to move upwards to far, needless to say that
this can happen even with higher weight oils, but the A-arm itself
pivots pretty far and the shocks need stoppers on the shafts;
to keep the bones from going to far, thus bending. I guess this also
may contribute to making the A-arms to stress by the hinge pin.

you can either use shock limiters or thicker springs, but in some applications
you want a soft spring, so in theory the stoppers would help.

The car bottoms out before the arms go to far, but if you land on one wheel
or nose down/up, you can make it go to far.

However, you can take the shaft out of the car and hammer it on a flat
piece of concrete to get them straight if you have bent them, as they are $45 just for 2 dogbones

I haven't heard about this...is this a common problem with the Hyper 9e? I had this same problem with my Hyper 10sc.

You are talking about the ends of the dog bones binding inside the outdrives. You should always check this when you build up a new car or make any changes to your setup. The shocks should be the up travel limiters. Take the shocks off and cycle the suspension to make sure it goes further than the length of the fully compressed shock.

I am surprised that this happened with the stock shocks. I'm using a shorter(when compressed) shock, and they don't bind on my setup.

Also make sure to make sure that the sway bar is not contacting the axle at full compression. I did have this problem.

No, I just needed a rubber bump stop on the outside of the shock shaft.
Along with a thicker viscosity oil in the front, note this only happens in the front

Everything is stock on my car, except the shock angles.
I have the front shocks on the 4th hole outwards towards wheel
and rear 3rd hole outwards, hints more vertical

And, so was I but still, I made a rubber bump stop to prevent
bending any more doggones, they are made of titanium which is pretty
strong if you ask me, just a minor bug to fix.

What is made of titanium?
