Ah, that explains.

Yeah the RRL12 is higher rated than the NSR. I guess it's the pipe you're using then that is limiting the engine RPM.

I know somebody (Goldfinger) that uses both the Max and the RRL12 and says that the RRL12 is only very marginally slower than the Max.

On the MTX-3, what gearing are you using?

Buddy, if you are in HK, go see Samuel of International Hobby in Wanchai. He is sponsored by Kyosho and runs a FW-05R himself. I don't think his car is slower than anyone else's out there.

I'll try my Rossy Pixy Black in the car but I only have the JPL pipe so might get the same problem

Ill try the RR12L5 in the Evo with the other pipe to see how that goes as well

D that explains it....ok will try the pipe set before looking for a MAX.
do u know which exact size/combo to look for?
the mtx 3 i use to run was stock gearing with a polished turbo crack, much like m.speed's

My appologies. No idea as I'm not too familiar with the piping for the FW05R. I'm told the test on the Max and the RR12L5 is done with a Novarossi inline pipe but I know that you cannot fit this on the FW05R !

That's funny... MTX-3 stock gearing is 7.42 and 5.43 for the 1st and 2nd gear respectively. If that is enough for your track, then 5.0 on the FW05R is definitely enough !

Internal drive ratio does not affect how much can the engine rev. Internal drive ratio is just part of the equation for top speed. You need to take into account the gear ratios or spur over pinion ratio (which gives you FDR) and tire diameter (which gives you tire rollout and top speed too).

So theoretically, a MTX-3 with a FDR of 5.0 ratio should have the same top speed as a FW05R with a FDR of 5.0... Taking into account that engine, pipe, clutch efficiency and tire diameter are the same...

FDR take internal into account. It is not the internal. Go talk to Samuel. He will probably tell you to get the pipe too.

I posted this earlier

The FW-05 with:

39 ring gear
45 Spur Gear
27 Pinion Gear
63mm Tyre Dia
40,000 engine revs

Speed = 59.38 mph


VoneRR Evo with:

44 Spur Gear
22 Pinion gear
63mm Tyre Dia
40,000 engine revs
No fast pulleys

Speed = 58.76 mph

My Pixy can rev out on the evo so will try it on the Fw-05
