    RE: Official HPI MT2 Thread


    ORIGINAL: Agreser

    I've had my MT2 for 2 years now and for some reason it runs at 420 degrees F and I richen it until it dies. Does this mean the motors on its way out and what should I do to fix it.

    What engine and how many gallons have you run through it?

    i now need a new clutch bell is it worth putting a 13t back on or go for a higher tooth one thanx. if only they used decent metal gears in the first place

    Is it the RTR and still stock? If so to change CB size you will have to all so get engine mounts. If you do change get the HPI Race CB and up grade the bearings as it will last MUCH longer then the poor RTR CB.

    got diffs back today and dont think they will last long they said they were shimmed up but it does not look like it and they even put some of the screws back in the wrong place and these guys are supposed to be profesional
    This is why I am the only one that works on my stuff. I would have had them send me the parts and done it myself!

    ORIGINAL: RCCanuck

    he's talking about drilling holes in the tires in the tread to let the water,muck,gunk out of the tires.....I have a set of beadlocks on my Monster Truck and they really aren't much heavier than stock...maybe a few grams thats it...

    Any rotating weight is a big HP eater. If just bashing no big deal but if you race could be a few seconds per lap. On my race Savage I run both light tires and rims for this reason.

    I do not drill holes in my tires I have a punch for this.

    the problem just started its a used truck I've put about 1/2 gallon thru.. so far
    Have you done anything to it right before you start having this problem? Is your wheel bearing OK? Is your diff OK? Is it just one side you have the problem with or both?

    I have the OS 18 TZ in my MT and started out with a very low gear like 14CB and 52 spur and could not keep the front wheels on the ground. I had to gear it up to 16CB and 47 spur just to keep the wheels on the ground most of the time.

    Ran last race round 8 of the Georgia Championship Series this past Saturday. We had a total of 160 racers participate in the series. They gave trophies and cash prizes for the top 10 each class over all. In my class 1/8 sports man I placed 10th. Not to bad for an old blind man that has only been racing about a year.

    RE: Official HPI MT2 Thread

    Still working on getting my new CV-RX 18 going. After many attempts the best i've been able to do is start it up for about 20 seconds before it quit. The glow plug igniter was still attached when it quit. I've removed the carb to inspect it and make sure that it was properly fitted to the motor and that the needles were at factory positions. The fuel is getting to the carb. The fuel is brand new. Now I'm having a hard time trying to get the thing started again. Anyone have this type of problem with a new motor??? Any advise would be appreciated.

    Try a new glow plug and lean the HSN out just a little. I have broke in quite a few engines and have never had a whole lot of problem.

    RE: Official HPI MT2 Thread

    Thanks! I just managed to burn a half tank of fuel. However I noticed that the fly-wheel is loose and not tighten onto the shaft. There are also metal dust shavings around it on the chassis. Is that normal? I closely followed the intstructions when mounting the flywheel and clutch.

    No if you put the flywheel on properly and get it tight should not be a problem. I have put many flywheels on and so far have not had a problem. Could very well make the engine hard to start and stay running. You need to take it off and make sure you did not mess it up to the point it needs replaced!

    Yep.... I'll need new clutch shoes and springs for sure. As far as the fly wheel is concerned; is it suppose to spin freely when the clutch shoes and springs are removed? What is the best way to remove it if needed???

    Thanks for your feed back.

    RE: Official HPI MT2 Thread

    When you turn the flywheel the engine should turn over and should not slip on the crankshaft! IF it slips you have a problem! This is the best clutch to run in the MT and is what I use in mine with the OS 18 TZ I have. All so the easiest one to put on and take off.

    Toss them in the trash. Most times when I replace my tires they are well wore out. On my race vehicles when they are to warn to race with I use them for testing and tuning as well as breaking in new engines so I do not mess up my good ones.

    Thanks 46U
    I took off the fly wheel and it looks fine. IT must have not been on tight enough. So I took off the pull starter and held one end with vice grips and got the pilot shaft screwed on nice and tight. Now the fly wheel is on there as should be. So now to get a new clutch shoe assembly. Thanks for the info on the racing one. Looks much more simplified to mount than the stock ones. Thanks again!

    I do not have any used MT tires right now but will have some shoot out buggy tires in the next couple of months. Now these are only tires no wheels as I reuse the wheels. I have not drove my MT in about 4 months. But hope to drive it and my Savage in the next couple of months, as the racing season is about over other then some club races.

    RE: Official HPI MT2 Thread

    Gruder, I see you have the cooling head from Nova RC, so I assume you have the alloy diff cups now as well? Have you had a chance to run the car yet? Do tell. I was looking at that cooling head for my CV-RX as well, how do you like it? It does indeed look nice. Have you noticed a drop in your temps, if so, how much? Heat is a big prob in the sand where I run, and if the new head shows a big improvement, I may have to get one also. The air scoop I made for my mt2 drops my operating temp about 20 degrees average, which is pretty good. More is better, though. Let me know if either the diff cups or cooling head are worth getting, if you please. BTW, your ride looks sweet. It just may be too pretty to run, lol.
    You can do it your own way- if its done just how I say

    Might not be as hot here as some places but it gets in to the 110 degrees and I never have a problem with stock heads and temperatures. Yes they do look good but the way I drive do not stay looking good for long. LOL

    RE: Official HPI MT2 Thread

    Cat,

    Yes I got the dif cases in, I had one that came in, in good condition, and the other one I had to ream the hole that the dif cup goes through a little bigger because the dif cup would not fit through. It is my belief that it missed the final boring process, no biggie as I have access to a full machine shop. Tower should be sending me my HD diff gear set should be here on Friday. The head looks good the diff’s look good too. As far as running cooler, that I will not know for a bit, the engine is not broke in yet, I will put the stock head back on to break the engine in then switch back to the good looking head and take some temps for ya. I do not have my radio equipment yet, that should be here with in 2 weeks or so. Just a side note, the head has more cooling fins on it than the stock head, also the diameter is bigger, I will try and post a picture if I can get one tonight when I get home from work.


    Hope you guys liked the truck.

    Thank you,

    Bryan
