Im just finishing one off and was reading the various threads here to see what extra info I could pickup, as usual instructions are light on practical detail and flying experience. Quite understandable. One thing i noticed straight away is the throws in the threads here are quite different from those in the build instructions, quoting another post they are said to be:

Aielrons 1.75" travel total. Put some expo on ailerons for less sensitive.
Elevator 1.75" travel total.
Rudder 2" travel total. Put some expo on rudder for less sensitive.
Flaps : Half flap 3/4". Full flaps 1.5".
Crow ailerons 3/8" up.

but for example the Cermark instructions say flap travel is 2/3 of that here. Hmm, who is right? anyone have stick experience of what works best? and is crow really necessary or flap alone ok? I use flap alone on my Kingcat without any trouble, I know some prefer crow mix. I guess that may be down to taste.

Ive heard alot about flutter problems but that would seem to be an issue with any model if care is not taken. Im not over worried about flutter ive always been a big fan of no slop linkage and no-gap type scale hinging (mass balancing in this moel might be a little tricky so ill skip that fo rnow unless its really necssary). Ill go easy on the throttle just in case...

Any other flight experience or mod experience of the Viperjet 2 would be greatly appreciated?
