Hi all
Just wanted to say that today I've maidened my Mini-Titan


!!!! And to say a big thanks to everyone here for helping with my newbie questions!
After my midweek cufuffle with having the aileron servos move the swash the wrong way, I'd fixed that and rechecked my pitch curves, eCCPM swash interactions, and cyclic pitch. I woke at 7 this morning and had to wait until the neighbours started mowing their lawn before I thought I could get it up. A few hops later and quite a bit of trim (right and forward) and I got it up in the garden (stop sniggering at the back!
) Checked the tracking and it was quite badly out - 2 cm between the blade tips. I set her down to tweak one of the top links to the blade grips but one turn made the low blade the higher one so it was still out. So I used the next links down (the long ones from the flybar mixer arms down to the swash) to try and correct. I got it closer but still not perfect.
Question. Apart from vibration what are the symptoms associated with poor tracking? I noticed that it seems like the rotor disk (or possibly the heli) is not level even though it is hovering without moving? That seems wrong, as if the rotor disk isn't level the heli should be creeping. Is that a symptom of poor tracking or is it that something else could be wrong?
I've just run two battery packs through with a 5 minute timer to see what was left in them (FP 2500 pack and a Revolution 2100),
It's an amazing feeling, that first flight....
Cheers all, time for a quick celebratory G&T
Bill
