    Tornado BB

    Hi all,

    First, is it normal when i put my something to block the tornado and put full throttle, the engine increase rpm but wheel wont spin at all. I think that is something with cheap offset clutch bell and clutch itself. What do you think??

    I have bought hpi clutch bell with 2 separate gear (hpi #83069, hpi #76977, hpi #76982). Do you think it will resolve a part of my problem?


    Second, i am thinking about put some silicone oil in my front and rear diff, which weight will you recommend?

    Last, I am living in quebec and here its cold, then is it normal that glow plug igniter (the one inckude in redcat starter kits) dont last more than 10-20 start?

    thanks all, your website is very useful

    RE: Tornado BB

    it could be that your stock clutch bell broke, i had one break where the teeth meets the bell. You could have stripped a spur gear too. you have to run the car, give it some throttle and see what is happening, i would say inspect the clutch bell first and see if it is broken. you can see this with the engine on the car, you can check the spur gears by turning it upside down and inspecting the spur gears, turn them with your fingers. The grub screws that hold your axle holders in place may be loose, there is one in the front and one in the rear of the transmission.

    Ok, thanks for input but i forget to say that i have inspect the clutch and its ok and spur gear too. All is ok but is the stock clutch able to put enought strenght on clutch bell to start wheel spinning?

    RE: Tornado BB

    i am a little confused by your question, what do you mean by when you block it with someting the rpms go higher but the wheels dont move. when you unblock it, does it move?

    Is this fact can lower the pressure the clutch can apply into the clutch bell?

    Ok but is the not round aluminium clutch bell can lower the efficacity of the clutch?

    And what about the oil silicone in my diff?

    thanks

    RE: Tornado BB

    once the clutch grabs it grabs, i am sure the steel one is more efficent and the diffs on a torndado are not sealed so oil would drip out, take them apart and grease them good, silicone grease

    RE: Tornado BB

    Why do you stop your car when you try to gas it. That can burn up the clutch [:'(] if you put your car against a wall no it will not always spin the tires and if you have done that a few times chances are that you have glazed or melted the aluminum clutch down enough that its turned to hard metal and won't work properly [X(] These cars are not ment to be abused like that, there just on the edge of breaking all the time, thats why its such an expensive hobby [:-]

    RE: Tornado BB

    you can improve the clutch bell by replacing it with the hpi 2 speed setup and 4146x high stall spring.

    if your tires are good it will be hard to spin the tires with knobbies on them ,they grab too much.

    you can try to seal the diff with silicone, and try to put diff oil in it, i wouldnt even bother to try since its not made to do that.

    You probably burned out your one way bearing while giving it gas and stopping it from going, or you burned you clutch shoes.

    Is it possible to raise up front of car on startup?

    I dont think the one way bearing is burned, are you talking about the one in pulled starter?? I dont try to move on gas more than 1-2 sec.

    So, nobody try to locked tornado diff?

    RE: Tornado BB

    I have never seen a number for the screw that holds the horn on (thats a T bar I think) its a machine screw that is related to the servo and not the model. I have them in the servo kits and some of the horn kits. Can someone else help if not I will check on tuesday if theres no answer [:-]

    RE: Tornado BB

    I have bought a tornado bb a month ago. It run's very good but a week ago it was not starting at idle. When i put a little throttle it start but when it goes idle it does not. The idle speed is set perfect. When I move it backward i hear a hissing sound from the engine gear. Could this problem be the clutch or the clutch spring??
