HK Durafly Auto-G2

The new Auto-G2 with autostart is now on the workbench. I viewed all the You Tube videos and there are a few questions;
* There is no motor thrust line offset and one flyer commented that it flys hands off up to half throttle but more power than that requires holding some stick correction. Does this sound like it may need a little down and right shimming to the motor ?
* The rotor head is factory set with a level attitude, but most heads that I've seen on similar 3-blade rotors have a 2 ~ 7 degree tilt to the left (facing forward). Nothing is mentioned in the videos and it looks to take off, fly straight and level and land nice and level.
* A mod that made sense and shows to work is to cover the bottom of the blades with duck tape with the excess wrapped over the top LE. I have done this with fluorescent orange.
* Only one video commented about balancing the blades and rotor assembly; Yes, I am doing that and yes it was out of balance with significant blade differences.
* I will make the first flights with the stock plastic rotor head, but I have the better all metal head which I will install after the tests and proof of flight.
* One flyer suggests re-bending the wire landing gear to make the width a little wider to help prevent tip overs.
* Larger wheels are also recommended if the field grass is too tall.
Anybody out there who has flown the Auto-G2 ?

G2 pitches up


I maidened my G2 yesterday and it pitched up to the point that full down would not level it. Is it the motor thrust line or head angle or CG ? I was using a Zippy 1300 battery and the aircraft had a slight nose down attitude when hung from the rotor mast.

Have been flying the Auto-G v1 for years (I think the only difference is v2 has pre rotating motor) and flies great with NO MODS apart from 35g lead on front as only run 1000mha. Everything like bigger wheels, adjusting landing gear, motor shims etc are due to other short flies great out of the box....unbalanced blades and all.

Instead of fitting blades with two screws replace one with a tooth pick.....just jamb in hole and snap off. When you tip over on take off occasionally the tooth pick will break as its the weakest point....not your blade or head etc
