A jet with D cups is the perfect toy.

YA, have you tried it w/o using Tam's unit to determine the air valve is working/properly plumbed?

Hi,

Not at all. I really appreciate the help. I wasn't able to get into the shop (the one with the aircraft in question) today, but I'll go through it again with all this in mind tomorrow morning and report back.

Hi,

Yep. It's a UP-3, and it's all plumbed properly and working flawlessly. The addition of the FS was weeks after the gear were installed and working. I'll just take a fresh go at it tomorrow and see if it's different with an uncluttered mind. I've done that before only to find I've hooked something up backward even after reading and re-reading the instructions ten times.

I'm willing to bet it's a problem with the TX setting and/or 'bind' setting. I'd also fill the air tank well beyond 50 PSI to rule that out as well.
