Reiko, Thats why I firmly believe everyone has a good side to them, sometimes you just havta break threw the crust to get to it. And some people are a bit harder to crack the shell, kinda like pistachio nut!![)]

ORIGINAL: Reiko

I can't believe this thread recovered from that carnage. The first several pages have been edited and hopefully everyone can stay on track here. The topic has wavered a bit which is not too bad, but what will not be tolerated at all is attacking other members, flaming, and taunting. There is useful information here, so please do not let the arguing lead to a lock.

Now, the topic may continue [sm=thumbs_up.gif]

I'm quite sure that after you dial the truck and motor in, you will find the power more than sufficient for your needs.

Hey Jamie, We really need to see some high resolution pics of the broken bell and shoes as I stated in the other thread you started. I would have to really think about what could be causing this one, but I'm sure its simple really. Get those pics and we can go from there.


And yes, the power numbers of the NX 7.7 is very hard to believe, but remember those numbers are subjective. All manufactureres are going to want you believe they have the most power, but as NOMOBUX said, once you have the motor tune in right you find plenty of power for any need you might find. In fact, these motors do enough power to destroy some very strong parts in the drive train of ANY RC truck.

I'm thinking maybe something is hanging up and causing heat or even stoping the bell dead in it's tracks. Is there anything exposed past the edge of the shoes? How's the mesh, is it binding up?

About the 5hp, every test I've seen they did it wrong or didn't show info on how the test was done. My truck has a big pair, felt like every tank brings my truck to life more.

This propably happened.....

http://www.rcuniverse.com/forum/m_7305904/tm.htm

The set screw bushing backed out of the clutchshoe.....ruined the bell..got a ******* explanation from Cen as to why it had happened.
I think it is a design error, maybe when the clutchshoe gets hot, the bushing detaches from the plastic and backs out.

Oh yeah, the debris destroyed the gear case + diff case also [:@]

Are you setting up an extremely tight pinion setting or something, is it straight and not cocked creating alot of pressure. .. we need some pics

To tell you the truth, I think your binding up somewhere. What do you use to set your mesh? Unless something in the tranny is getting stuck, I think it's hanging up and making the shoes slip like I've never seen before. I'm almost at a gallon and a half and my bell isn't scorched like yours is, just getting a tan/brown color on mine.

Jamie!!! Poo is on to something!!! You have a major problem there bud!! Sure the CB will get hot, but not that hot!! what is happening is your CB is getting VERY hot on the outter clutch surface and not so much in the center. The CB's are hardened steel so when they are exposed to that kind of heat then cooled down they can and will get brittle/crack at the thermal zone(Where the hot meets the cool), creating a weak spot. You need to find out why you are cooking the Clutch before you change another CB. I would check all everything on your drivetrain. In fact when your truck is up off the wheels try to rotate the wheels and see how easy it is turn. Everything should spin freely!!

By any chance are you driving this truck in tall weeds or grass??

jamie, do you run with your fuel line on the head like that?

Can you get a better picture of the gear teeth? I can't tell if it's the light or if your teeth are starting to eat the outer edge.
