: What motor for a racin Revo??

01-02-2006, 08:51 PM
My local track up here (Darwin) has finally included a truck class to it calender https://www.ausrc.com/forum/smileys/smiley32.gif
By the sounds of it I'm going to be racing mostly against Truggies & converted 1/8th buggies.

I'm thinking I might need a bigger or faster motor but I'm not sure which way to go. Either with the OS .18 TM or the RB 323.

I know there are guys who have both on this forum & was wondering if you could give me some advice.

I've seen the OS .18 in a revo and i wasn't impressed. Not sure if his truck had issues or was it just normall for that engine. Seemed to have abit more bottom end than the 2.5r but less top end. Just what i noticed on the day, like i said not sure it thats normal.

Basically its up to you I know that the RBs have massive low end grunt and are suppossed to provide really easy wheelies, but if your serious about racing than that will just annoy you. I've run the OS 18TM before and it is pretty good all round lots of low end and no real trade off in top speed. But I think it would be more beneficial to lighten the Revo up a little and get the weight distribution right before changing the engine. But if the TRX 2.5 is getting on then by all means change it but a change in motor will not usually make you go faster right away

IMO, RB TM323 all the way.

I have 2 Revo's each fitted with the TM323 and OS 18tm and I'll offer the following:

- both engines would suit racing although as Revolution stated, the 18tm comes alive with some weight reduction

- the tm323 has massive bottom so look at gearing it higher with something like a 16/36.

- if you're running long mains, then fuel economy is an issue. The RB is thirsty so consider a spyder tank mod

- the RB is a breeze to tune whilst the 18tm is a little easier than the 3.5r but not by much

- choose your plugs carefully. Have tested OS, McCoy, Traxxas plugs but found none that perform as well as the RB plugs. Hard to find in Oz but they can be found.

- the Slipper set up is your friend. Adjust it carefully for a balanced feel

- Orange and black rocks.. 18tm looks like a standard 3.5r

- 18tm = 4 cyclinder turbo charged japanese import....

- rb tm323 = v8 muscle car

I'm biased towards the tm323 but again, that's only my preference.

my mate has an RB .23 in his revo aswell, theyre an awesome motor thats for sure.

RB motors are amongst the best in the world as far as quality + performance.

Thatnks for the advice.
I was only thinking I'd need higher gearing for the RB but wasn't sure what.

I've been trying to find info on the tank mods people have been doing. I've heard of the "mugen tank" & the "spyder tank" mods but the Traxxas forum search isnt working https://www.ausrc.com/forum/smileys/smiley7.gif

Can any one help me with a link or some pics maybe??
