I just got my MRX-4 and I went with OS, this is my first 8th scale car and I want to learn to drive it well I can go fast later, I am saying OS is not fast, but it has more of a easy driving feeling. And I don't get nervous from all that power. If your a first time driver like me go with OS.

RB stocker is good engine to learn or if you are inclined to spend more coin you could go with the Rody tuned one.

Now if you are full of cash you could get the JP R0-3 fastest .21 I have ever seen

thanks guys, but will that jp last as long as the rody, I've heard the jp and rex don't have the longevity and i plan on running one motor for a while. have some cash but don't have motor sponsor like some other racers. i can't just lean that puppy and load a new motor for the mains. but i do like to have the best that their is if it helps overall in lap times, there's nothing worst than driving your best and not having enough ponies under the hood. thanks again Peter

Default RB

We are running a Rody C5, ran over 700 laps in Florida at the Full Throttle Race, The car was second qualifier and finished second against a fast bunch. The motor is strong - replaced the rod and I bet we'll run well over 6 gallons in this motor by year end. Plenty of punch, good top end and the motors are very well built. The C5 would be a great choice.

I have a RB C4 with a brand new RB 9886 polished pipe & header. Engine still has good pinch going over TDC, no pits in combustion chamber, bearings smooth, about time for a new rod.

$225.00 shipped, Paypal OK

isn't the RB C-4 an off-road .21?

Peter,

get a serpent mega .21 engine. they are inexpensive, have been proven already, and have local support from Serpent USA.

Default On-Road

It's a 1004-C, The "C" is for Circuit.

A 1004-B is the offroad version, "B" is for buggy.
