I scratch build a lot of flying wings.
Small , Medium and large wings and in general they fly fine .
Mostly the behave fairly predictable .
My favorite wings to fly at the moment are quite small at about 600mm wide .
They are quite fast and fun to ramp up and dance around the sky.
Now recently i have noticed some strange behaviour (Not on every flight because yesterday i flew all day and it didn't happen at all).
But when it starts it seems to last that whole session.
What happens is when i punch the throttle it wants to bank left and dive (I don't believe it to be engine torque as i know what this feels like . This feels more like a servo thing . I Have tried the following.
* Re-centered the servos and pushrods. (re-trimmed)
* Checked that there is no play in control surfaces
* Motor mount isn't loose.
I'm stumped .
Anyone else had this problem or have a solution ?.
