Need some answers to help a friend get his Cermark Viperjet put together:

What's the servo requirements / recommendations ?

Nose gear doesn't fit the installed mount (steering arm binds hard against the lower fuselage), so the mount will have to be redone. To get this right, should the aircraft sit level or slightly nose high ?

All wing / stab etc mounting screws are missing. Anyone know what the right sizes are ? (I'm guessing they're probably some kind of metric thread).

For gluing the control horns into the ailerons, flaps, etc., are there hard-points already in the surface ? If so, where are they so that we can ensure that we cut the slots in the right places ?

Thanks in advance for any answers you can provide. There may be some more questoins coming soon...
