The o.s cv-rx or the fantom fr18.

InfinitySpeed04

That depends what kinda car are you putting it in. The most dependable for under 150 is the O.S. .18 cv-rx. Thats what I am putting into my evader.

David D

The os .18 is the most dependaple and powerful .18 next to the tm and tz which are over your price range.

InfinitySpeed04

The tz would melt an st diff. If you want something you can control the cv-rx is the best bet.

annie_himself

the phantom is under 150 wow

anty

If it were me, I would drop the extra 30.00 and get a TZ, from the few I have seen at the track they are an absolute beast.

OS .18 cv-r Just enuff power to keep you happy and not too much to blow out a diff.

annie_himself

keep that in mind

InfinitySpeed04

The tz will definitely blow a diff. It has way too much power for what you would be using it for.

Kemo

yeah, the only TZ worth dropping in there would be the .12. Heck, they dyno'd it and said it has the take off like an electric... thats fast.

What if you upgrade to an alum diff?

InfinitySpeed04

You could try but I have people tell me to stay away from the TZ because it has too much power, you can blow a diff, and you will have very little control over the car. You can go ahaed and get an aluminum diff but something else will give out farther down the line. Putting in aluminum only moves the pressure to another part of the car. Think about it, when you get an aluminum shock tower the crash sends a pressure to the shock tower but because the tower is more tough it diverts it to another place like the bulkhead. Trust me Getting the TZ will only create more problems down the line. I ahev had experience with this.

I'll mod all the gearing with metal parts so there isn't a weak point in the gearing?

annie_himself

ill get the cv-r thanks

anty

p u s s y ...

annie_himself

InfinitySpeed04

Yeah that is avery smart idea. Good choice

The magazine RC Action did a comparison of all the .18's out there and the OS was the best. I posted the results here in this site somewhere:

Found it:

Just installed my CV-RX in mine. I can't wait to break it in. My .18SS was getting tired and I just read the latest in Radio Control Car Action magazine. They tested the following engines in a Traxxas Maxx using Trinity 20% Racing fuel:

Epic .18 Big Bore:
Top speed - 39.15 mph
Time to reach top speed - 6.94 sec
Time at 132 ft - 3.85 sec
Speed at 132 ft - 33.42 mph

Fantom FR .18:
Top speed - 36.41 mph
Time to reach top speed - 6.62 sec
Time at 132 ft - 3.89 sec
Speed at 132 ft - 33.49 mph

Hot Products .18 Outlaw:
Top speed - 36.65 mph
Time to reach top speed - 7.49 sec
Time at 132 ft - 3.96 sec
Speed at 132 ft - 32.21 mph

HPI Nitro Star .18SS:
Top speed - 36.78 mph
Time to reach top speed - 6.85 sec
Time at 132 ft - 3.91 sec
Speed at 132 ft - 32.42 mph

OS Engines .18:
Top speed - 40.40 mph
Time to reach top speed - 6.27 sec
Time at 132 ft - 3.42 sec
Speed at 132 ft - 38.15 mph

Peak Racing Diablo:
Top speed - 37.05 mph
Time to reach top speed - 7.87 sec
Time at 132 ft - 4.02 sec
Speed at 132 ft - 31.97 mph

Sirio TX-18:
Top speed - 37.31 mph
Time to reach top speed - 6.50 sec
Time at 132 ft - 3.89 sec
Speed at 132 ft - 33.86 mph

Team Orion Wasp .18:
Top speed - 30.18 mph
Time to reach top speed - 6.40 sec
Time at 132 ft - 4.69 sec
Speed at 132 ft - 27.48 mph

XTM .18:
Top speed - 30.56 mph
Time to reach top speed - 6.85 sec
Time at 132 ft - 4.20 sec
Speed at 132 ft - 29.71 mph

From these numbers it is easy to see that the OS was the only enigine to hit 40 mph and was able to get to 132 ft the fastest a full 1/2 second quicker than the next engine.

I still think it's funny that Traxxas says that the 2.5 would have kept up with any of them:P

InfinitySpeed04

Those Traxxas people

Kemo

Ha, complete bull. That 2.5 is basically garbage. It doesnt know when it wants to run right or not

InfinitySpeed04

Yeah I hear you. My friend has a 2.5 in his car and it rarelt wants to start. It has to get pissed[>:] and they maybe it will get scared and start for him.[sm=biggrin.gif]

Jamxx

I concur about the 2.5 engine. It reminds me of an ancient Egyptian pharoah...

He went by the name of Pupianus. Or something like that...

One day, mine ran well with the HSN 3 1/2 turns out. The next day, it wouldn't start with this setting. I tuned it again and it ran well at 3 turns out. Keep in mind that the temperature outside changed 3 degrees and the humidity changed about 2 percent. I mean, come on!

Kemo

THen they came out with a graphite piston/sleeve kit... oye. Like that engine needs more plastics on it.
