2600 Kv rated motors? which one? - Page 7 - RC-Monster Forums

Yea, its a decent deal, but the clutch is the reason I wouldn't get it...

Revracer · 01.11.2008, 12:39 AM

what is wrong with the clutch? you set it loose so it instantly grabs when you get on the throttle i would think. or set it tight to give even more bite. i think its a good thing personally. why would you say its bad?

Revracer · 01.11.2008, 12:46 AM

and it will be both a good basher and racer? does it have the torque and speed to outrun a 3.3 on the track? given the same driver and all?

Having run a 3.3 revo, I am not really impressed. The lack of low end torque and poor throttle respose really seem like a problem for racing. I do not race, however I can control a rc vehicle well, and apreciate the various suspension adjustments, etc. I would say that a brushless system (of any type) would be easier to drive due to its relatively flat torque curve and linear horsepower. I have not seen a slow brushless vehicle yet, and do not see a nitro vehicle being able to top out, speed wise, before a brushless would. The acceleration is so much better with a brushless setup. There is really no comparision. We ran the 8l revo in front of a few nitro revo owners and they were all very impressed. They tried to drive it and said that it was too powerful (for their skill level, HAHA!).

Personally, I think the clutch is something that should stay on a nitro engine. I think its a good idea, especially for some applications, but not a Revo. Another thing to consider is the fact that from what people have posted, it seems like it will kill your runtime. Its just one more thing thats not necessary. I use the RC-M mount and with the center diff, it takes off great, no cogging, and wheelies aren't an issue (wheelies are useless in a race anyway) and everything can be kept stone cold. The MM was getting a little hot, but only cause it was overgeared slightly and I was using the internal BEC.

People have posted issues with runtime due to the clutch? Strange, my setup gets great runtimes, at least 35 mins and usually closer to 45mins, mixed bashing. It is an aveox 200kv motor, quark 80 airmaster and 5s 5k lipos.

Not exactly. Its just from what I've seen, people were only getting around 2/3 the runtime they should be getting. Like 20 minutes with a 8000mah pack.

lutach · 01.11.2008, 11:25 PM

That's where the Mega and a Quark 65 or MGM 80 would come in hand.

Revracer · 01.11.2008, 04:57 PM

okay well im deffinetly getting the 8l and the mamba max. tekno kit is gonna happen. im set on that. and my maxamps 5000 3s lipo should provide plenty power for the truck right? easily enough to make it lift tires up and good speeds?

lincpimp · 01.11.2008, 10:04 PM

Yep, the 5k 3s pack and the 8l should do what you want!

Revracer · 01.11.2008, 10:30 PM

very cool. thanks yall

Revracer · 01.11.2008, 11:26 PM

no tekno got 20 minute races in on one battery. and that was a 3s 8k. bashing they claimed over 35 minutes.

This is why 3s is not that good, step up to 5s and you will see that a 5s 4000 packs will give you better runtimes that of the 8000 3s. Plus all of the equipmeent will run cooler. Say that you are try to get 1000watts out of a combo, on 3s you need 90amps. On 5s you only need 55 amps. That makes a huge difference on equipment temps. Same esc, same size and weight motor, just less kv, same overall motor and vehicle speed, same gearing. it will run better with higher voltage.

I can imagine that the tekno setup with the 8000 3s gets warmer than a similar powered 5s setup. Plus considering that a 8000 3s pack is made of 6 4000 cells, a 5s 4000 will weigh 1/6 of the 8000 pack. Less weight means better performance.

yes but when you look at my price range.... i cant even afford to get a 4s system... i basically HAVE to use 3s for probly 6 months or so...

That is why the 8l is so great. You only spend 60-70 bucks inc shipping, and you can sell it when you are done, or put it in a different vehicle. Have fun!
