Hi Patrick,
We had problems with vibration in that rpm range that had us stumped for
a while. It turned out to be a mis-match in the prop blade incidences
on our Airmaster prop. As I recall, one blade was almost one degree off
---From the other two. Turned out to be a problem with the blade followers
that was eventually corrected by the factory. Depending on how the
blades were installed in the hub (and the orientation of the followers),
the incidences could come out fairly close, or be rather bad.
Regards,

Hope you have all your problems sorted now Ferg. There will be more!!
My particular one is vibration. Horrid airframe vibration between 2000
and 3700 rpm with my 914. Fuel drained and refilled, filters cleaned,
carbs cleaned and jets., carbs balanced with proper kit, set of new
plugs fitted,
engine mounts checked. New Arplast prop back in France for
re-balancing. All
plugs show equally nice and grey. I have run out of ideas. Has anyone
experienced similar problems and can suggest any other areas of search
please ?
Had no problems with the old Warpdrive (now defunct).
Patrick
