I've a Seagull Funfly 3D with an Evolution 10cc swinging a 14x4W funfly prop that I'm anxious to try the throttle servo delay on. Controlling pitch on landings has always been more difficult than the rest of my fleet. In fact it is the only plane I run 60% expo on and still it is challenging.
Sometimes I swear that the slower it goes the more pitch sensitive it gets, but I've tried balancing further forward but gotten no relief. And... it doesn't linger down the runway like it is tail heavy. It is just pitch sensitive at slow speeds. Maybe it needs more expo at slower speeds.... who knows?
What i do know now is that I'm going to play with an elevator servo delay with it.
