I read that article too, which is the motivation for doing a lot of searching on this forum and putting it on my favorites list to monitor.

Last week, while at a fellow modeling buddies house, I mentioned I was going to attempt converting a weed whacker into an R/C engine. As luck would have it he had Weedeater brand string trimmer that had seen better days and he let me take. This unit has the same 18cc Poulan that was converted in that article, with a few differences. I will not need to change the carb and it needs a different prop mounting system.

So far I’m about 80% done with the conversion and it’s been easy. I re-read that article just the other day and some things make more sense after tearing into it. Can’t wait to get a prop on it to fire it up!
