Hello Mike!

I've read somewhere that you suggested a test to determine if the differentials are correct which I didn't know of. If I recall right, you said to roll inverted and see how much the nose drops and then repeat the test from inverted to straight flight.

Can you state more precisely how to perform this test and what we are looking for here? Why should that be more useful than the classic differential test (i.e., downline or 45 deg with full ail)?


Many thanks for your replies, they are greatly appreciated.

I have never done a downline 45 test for ail diferentual. How does that work? The roll to inverted and back to upright, with no top rudder shows how it reacts one up to inv vs the vice versa. It should react the same. That is only one test though. Its also important to check on vertical up and down lines in continuous rolls.

Thank you Mike for the reply!

Regarding the test, I mean the classic 45 deg upline rolls... ooops!

How do you perform it? For example, left ail until inverted and then right ail back to level flight?

I'm interested in this test, do you find that it can suggest more fine regulations than the other tests? What test do you perform first?

Hmmmm. I'm not sure what that 45 test would how. You are also comparing a left roll to inv to a right roll to upright. Really need to compare in the same roll dorection. Diff could be dofferent in opposite directions.

I notmally do the roll to inv and to up right first then the vertical lin tests. With computer radios today, that all takes about 5 min to do and dial in in the air. Isnt technology amazing!! Used to take many flights and lots of work to dial in diff.

Try this, pull your 45 upline and roll in one direction. the direction it "walks" reduce that ailerons throw. Try the trimming video at www.teamflyingcirkus.com. It has some good info too.

Thanks Spun,
I've already seen it! Great video!
