For those that have converted their 3W's to a CH ignition. Did you drill new holes for the sensor? I can just barely get 28 degrees with the existing holes. I got a bit of kick back so I may need to retard the timing a bit. I am wondering what the typical sensor mounting method is. I think the hose clamp idea is kind of cheesy.

I also thought the hose clamp would be kind of cheezey........but after installing it I changed my mind. The clamp is not overly large, but rather "just right". It's actually a very neat installation, and you would be hard pressed to see it on any cowled installation.

I believe the hose clamp is needed to get the proper timing on the WWW engine.

So I say...."don't fear the hose clamp"

For what it's worth.

just curious.. why would you put a CH ignition on the www engine?

Because they work..

My experience was that the WWW ignition system was not working properly. I messed with it for two years and could not get the issue resolved with AI. So I installed the CH ignition, and have had no further issues. I am happy with the engine now but have since changed my loyalty to DA. (to be fair my DA had some issues also, but they all have been resolved in a timely manner)

I have a friend who had similar issues with his WWW 106. He messed with it for almost 3 years, and ended up selling it. He now flys DA.

Just my experience; I know there are a lot of WWW engines flying out there. In fact my first "big" engine was a WWW 100. It was a great engine, and I'm sorry I sold it......

Apparently there was a discovery that heat was the issue with WWW igs.... mounting them with an air space under the base is the solution.

I normally do that.....and I increased the "airflow" under the module as part of my many troubleshooting items....to no avail.

BTW Mithrandir, that was an informative video you did regarding cutting the exit holes in the fuse for a pull-pull system.....I saved "that guy" for future reference.

I bought a 3"twin from Air hobbies , the motor run for +- 2 tanks then the ignition decided to stop working.

As I live in South Africa I can get Rcxel ignition .

Will the current pickup work. I can move I easy by drilling and tapping new hole.

Any help will be appreciated

subscribed Been considering CH for my 3W 150TOC, But the reported kick back worries me some. Can any one list some pros and cons. A link to CH would be nice Thanks in advance. RutnBuc

totius54, the RCEXL comes with a new sensor BUT your existing one might work. The instructions with the new ignition will explain this.

The kick back is caused by being too far advanced not the ignition itself. My 3W ignition did the same thing when it was advanced too far. I converted mine because my 3W ignition failed after 3 flights. It was not a heat issue since I had it mounted on 1/4" blocks for cooling. When I sent the ignition that had a total of 8 flights to a certain 3W service company for warranty replacement. He sent me back a used ignition as a replacement. I figured I would be better off with a CH.

I had some problems with a certain 3W dealer out your way also. I switched to the other dealer in a colder climate, and have been very happy since. I haven't seen any ignition problems, but it sounds like there certainly may be some issues.

Thanks Jim, I will try to get over my fear of the hose clamp I guess by the time the prop and spinner are installed it will be blocked.

thanks cant wait for its arrival , then its time to play

In to days technologically advancements these Ignition module failure should not happen , Air hobbies wants me to return post send it back 1/2 way round the world ( the postage would cost more than the ignition) . My point it should not have failed. I used 6 volt supply maybe i should have used 4.8 volt . But it should not have failed point.
