Rising Storm, what's next?

[OneyedK]

I've got one Rising Storm build from the kit...

+ Carson suspension and ball bearings

Everything else stock.

Since I have two children [}] I also bought a 2nd hand

Rising Storm XB. Everything stock.

The motor of that one was worn, so I changed it with a

Graupner Speed 600 an a 18T (instead of 19T) sprocket.

Will change bearings in the near future, Carson suspension

is very good but a bit on the expensive side (so I use the CVA's from the other one)...

The questions:

First buggy runs fine, but is not exactly punchy so I guess a 540 sport tuned would be a nice option. Leave gearing the same???

2nd one is very agressive and a little faster than the first one,

I like to drive this one best... But battery life is 30% less...

Can't imagine that only the plastic bearings are responible for that?!

I only started playing with these beauties a few weeks ago so I don't have any experience. Hop-up suggestions would be nice...

Ah yes, at the moment I'm using 2 Nosram 2200 packs an 1 Sanyo 2000Race... RC3300 saddle pack is on it's way[]

Thanks for your suggestions!

I think this can be put down to the motors in the kits. The standard motor has 15000rpm so is slower, but a current drain at best efficiency of about 6A, whereas the Graupner Speed 600 has an RPM of just over 18000RPM (faster), but current drain at best efficiency of about 12A (I think)

If using a sport tuned motor (18,300RPM) I believe you can use the same gearing, and the current drain at best efficiency is about 12A, so battery life should be about the same as the Graupner.

Thanks Tipsy, this explains about the shorter runtime (still a good 30 mins with the 2200 packs).

Will experiment a little more with different gearings to see what happens...
