For a lack of a better word I am obsessed with making conversion kits that will allow you to use a RCexl ignition on most of the popular RC gas engines without having to make changes to the engine.

Have done it for DA/3W and ZDZ engines and had a Evolution sent to me to convert to RCexl ignition.

Tried to redo some of the sensor brackets for some of the other engines conversion kits but could not get any of them to work the way I wanted them to so went back to square one and the universal sensor bracket that RCexl makes.

After a couple day's of trial and error with trying different heats and forming tools I finally got it worked out and can shape it to work on the engine.

So now we have a conversion kit for Evolution/MVVS engines that will work in the existing mounting holes with no changes made to the engine.

I use a tie wrap to hold the sensor to the alternate magnet. Much easier!

I can understand that but a lot of people do not like flying there planes with the sensor held on with a tie wrap.

I know, but...
It works. If it does not, there is a major cooling issue. Better to have your plane come down with reduced power, than to fry your engine.

Use your imagination in what could go wrong when using tie wraps. So far, it proved ultra reliable and is easy to adjust.

I like the tie wrap idea. Once I find a timing position setting, I can glue it in place with a little silicon adhesive too.
I was getting ready to convert a engine over and was thinking about making a metal adapter ring for the timing sensor. But the tie wrap is pretty good and saves me alot of effort.

Milton,

A smart setup you have there. Can I suggest a slight mod though, i see the elongated holes in the bracket have the bolts through the opposite ends. A slight mod to have both at the same end of the slots and you can adjust the timing back and forth by a few degrees.
I like your work on this
