Note on filters: The YS .63 manual does not
show (2) filters as do the manuals for the larger YS engines. That being said, I'm running (2) filters on the .63 I'm currently using. Between tees, filters, & check valves, things can get cramped in a tight engine install; check out these: http://www.centralhobbies.com/Fuel/f...a/TET4307.html
for a bit more compact set up (filter & tee as one unit). Central also sells a very small filter not listed on their website (can't remember the exact name but they'll know) that is much
more compact than anything you'll see in the hobby shop or elsewhere.
The dots & tees are pretty fool-proof but, on the other hand, I've never had a problem with the Dubro filler valves in this application so I suppose I'll continue using them.
