I love my OS70 4S in my UCD. It has plenty of power though I'm not hovering or doing any of those crazy stunts yet but you gotta love the instant power of the 4S.

I flew my bird more today to keep trimming it - I've added some right thrust and it seems OK in that area now. What I'm working on now is lateral balance.

My plane balances almost perfectly statically but in the air I trim the plane to fly straight and level then fly inverted and it's dropping the left wing. I've now added some weight to the right wing but it's a little too much so I now need to get some off again. It's taken about 7 flights so far to get to this point and I'm a long way from finished. It sure is an effort to properly trim a plane out

I've never bothered with this trimming stuff before but I really want this plane to fly true so I'm going to keep going till I get it perfect.

More to come,

Regards

Tony
