Addiction? What addiction??! I can quit any time I want. *twitch*... *twitch*

Yep, count me in too. I have:

2 single-ring Ryobi 31cc
1 twin-ring Ryobi 31cc
1 Cub Cadet 25.4cc
2 Poulan 46cc
1 Mac Minarelli 70cc (well sort of, but I did buy this one bare block)

Sooner or later I'll chop up that Ryobi 26cc 4stroke weedwacker in the garage too. I'm also eyeing a couple of re-furb Echo engines at Home Depot too.

I do have a few ARF boxes piled up in my study waiting to get built, but I must admit I have wayyy more engines, both RC and conversions, than I have airplanes. I too am having more fun converting engines than flying airplanes these days.
