  3. RE: BAJA SRT4 100cc gasoline twin cylinder 2-stroke 1/4 scale

    So why didn't it start before? Have you found the reason why it didn't work?

    It is very loud, I like it!

    The coils are not included, the system is meant for marine use where they have a source coil for making a few 100's volts and this voltage is put into the high voltage spark ignition coil. So you...

    I haven't used the system myself, so I don't really know. But there is a contact page, try to contact them directly with your questions.

    RE: New CDI - opensource project JMJ and Bigboat

    Bigboat, the advance is low at low RPM and advance is higher at high RPM. You got it the other way around in your post.

    RE: Creating ignition curve for Zenoah G260RC

    Pe, thanks for the book, I'll read that, and Greg thanks for the dyno explanation and links, I can see you are right about the timing at constant RPM, it's not the way to do it.

    No, I would just like to see the pictures to better understand what you were talking about, but if that's too much to ask, then just don't post any pictures ;)

    Okay, you might wanna hit me with a pic of the different heads you are talking about (squish head, domed non-squish, taper squish). I have no idea how the different types look like.

    Thanks for the reply.

    I think most of the time we drive throttle ON/OFF on our 1:5 scale cars. But I will definitely try your suggestion.

    According to the engine manual, the ignition is 30...

    Hello forum,

    I'm building a homemade CDI ignition with microcontroller control for Zenoah G260RC (for largescale cars).

    How do I test this engine and create the best ignition curve? By...

    RE: New CDI - opensource project JMJ and Bigboat

    Hi Dave,

    You need to remove some of the plastic in the transformer to make the windings fit. There are some "walls" seperating the windings, these need to be removed. Have you done this?
