RE: u-can-do 60, use a cline or what?
Glenn,
I have a UCD 60 with Saito 1.00 mounted inverted.
I have a Great Planes fueler on it...no pumps, no regulators.
The tank is in the stock location.
When I first started flying it I was worried about it siphoning fuel while sitting, etc.
I can let it sit fully fueled, throttle closed with no problems.
I have had no problems with it leaning or richening in flight but I run it on the rich side top end.
It idles well with no issues.
Good luck.
JLK
