RE: Which Stik (stick)?
I have a .40 size... .60 size.... .120 size H9 Stick's...I love them all!!!!
But who told you to put a 100 Saito on a H9 .60 Stick???
A OS 61 FX will fly that plane great...a OS 91 FS will fly it to the extreme!!!
With this being a "Second Plane" I would with the smaller engine then work my way up.
Just my opinion!!
