Hi from down under, I have just re-discovered my RC collection, they are a bit battererd but I love them. My First was a Sand Scorcher, which has been modded a lot, it was the fastest out of the 3. The Super Champ was a full import job from Japan (very stock) except for the broken body shell. The Yokomo Dogfighter I purchased when worked in a hobby shop back in the 90s, it never saw satisfactory completion and is near new. I think that they will now all remain as static models, perhaps with a little more TLC now, i have time for them again.
