1) I run the car on a very technical cement carpark track, and I found the car very loose at the rear off-power. A slightly more input on the steering will cause the rear to break out, and the car felt very nervous (talking about off-power). Was running one-way, 4k rear diff oil, tried position 3 and 4 for the rear shocks (no help), long black spring up front and long gold spring on the rear, both ends with antiroll bar with the front set at “—“. I'm using foams, tyres are of no issue as I'm using the right shore for the track. Any recommendations to rectify the problem?

2) When should I be using thick/thin diff oil? And their effects? What are the recommended diff oil to experiment/stock up? I was thinking of getting 5k, 10k, 20, and 30k.

3) I found that (by feeling… ) the SHORT BLACK spring is STIFFER than the LONG GOLD spring, hence the use of the long gold spring at the rear for my setup. Is the shorter black really stiffer than the long gold just to make sure?

4) Question on radio…I got to know that we can’t use analog servos on 3PK with HRS. How about the Helios HSR? I’ve seen people using analog servos on MARS R with Super High Speed Response system…but is it ok to use the analog servos with the Helios HSR?

Thanks in advance!

Thanks for the tips darkangel and spawn. I'm still not sure...how does thick/thin rear diff oil affects the handling of the car on one-way, off-power and on-power? Anyone care to clear the myth on the Kyosho' spring rates that I mentioned before?

It could just be the spring combination I used, having long black up front and long gold at the rear. Is it advisable to run stiffer spring up front when running a one-way? Previously I was running the NTC3 with harder springs and tire shore at the back with great performance and handling.

Ok...I know I've asked this quite a number of times.....but seems like it did not get answered, or no one actually knows the answer? Is the SHORT BLACK spring STIFFER than the LONG GOLD spring??

Yo tommi!!!, using heavier diff oil is the same effect as tightening the ball diff. When using one-way you want to have thicker diff oil. Some of the pro racers who came over from overseas to race in Titi were using 30k diff oil in the rear. It will reduce the possibility of spinning during hard braking. Try it.

But Sydney, being quite a good racer himself, was using the setting I mentioned before, so I guess I may give that a try...but things didn't quite turn out the way it should be. Guess it's better for me to work from the stock settings...

just got myself a V-one RRR... been using v-oneR for years... this car is so good... it handles very well and its so easy to set-up.. i love this car...

anyway, i heard from some other forum that Kyosho is further developing the RRR and might be releasing a later version of the RRR. DOn't know when.. don't know what changes they have in store.... The car is already very very good in itself but what do you guys think kyosho needs to improve or add to the RRR? i'd say the rear shock towers should be reinforced... dunno what else needs to be improved.. what do you guys think?

Ive never had a problem with the switch on my v1RRR, and find it MUCH better than pulling a connector in and out all the time.

I can post some pics of the wiring job if people would like to see, turns out much neater with the switch.
