    I've repaired many RCExl ignitions and all had the regulator chip on the timer board. Usually, the ignition circuits have been of the same design. They are reliable at 4.8 volts, not so much at 8.4. ...

    I don't have a website. I use my email for everything.

    Hi Ernie.
    I normally recommend a 4.8 voltage from whatever source you are using. In the case of LiPo batteries, I use a short plugin harness to the power lead of the ignition with the correct...

  6. RE: how to attach a magnet to a Webra Prop Hub?

    Hi Oddy.
    One way is to make a sleeve (tube) that will slip over the prop hub diameter, drill it for both the magnet and a setscrew to make it adjustable. I've done that a few times. Or another...

    RE: Little Zenoah grey coil??

    Here is a pic of one of the many coils that I have. It is made to be used with a CDI. If this is what you are looking to replace, it will work great. Very low primary resistance, again intended for a...

    RE: CDI gr8flyer55

    Rob, looks like you have the timing problem solved, and your ignition is working good with lots of spark energy at high rpms.
    Very nice indeed!

    Hi Stew.
    Seems like you are in need of a CDI upgrade for your system. Our CDI is probably adaptable to your system with some minor changes made to it. Ours requires a dedicated power supply that...

    RE: CDI gr8flyer55

    Ray, the fixes you made on the excel sheet seem to work good. There are few if any problems in the software except the rpm limitations. So, if it is used on a regular gas engine in the 7,000-9,000...

    RE: New Evolution 10cc gas engine

    Looking over all the pics they provided for the 10cc engine, it seems any of the 1/4-32 thread plugs should work. There are a lot of web sites offering them.
