I'm in too. I've got several single channel systems here gathering dust. I'm just finishing up a original Jr Falcon with an Ace system in it. Just have to cover it. Tim Wiltse is building a couple of Sure Starts with the larger tanks for this purpose for me. If anyone is looking for an Ace or a Mattel I could probably see my way clear to selling a system or two. They have been re-wired with new batteries and tuned by an ex-Ace tech. I'm not out to make money. I'd just like to see someone else have as much fun as I have making these things work. Otherwise I don't see anything wrong with "cheating" and using one of todays micro receivers with ONE micro servo. Not fair if you put a throttle on it.
