REFLECTOR:Considering alternate engines

Hi Chris,
I'm using an IVO behind a Marcotte drive and have been "entertained" by an
airframe resonance problem since I started using the combination. I
eventually added 5 grams of buckshot down the hollow torque arm of one blade
and short double layers of leading edge tape on 2 blades to balance the
prop. My new dynamic prop balancer worked well and the problem is now
negligible above 500 RPM.
The brush rigging supplied was really cheap but it was easily replaced with
a GM alternator brush holder and brushes which hold up very well.
IVO supplies two lengths of prop bolt too long and too short, another
easily bypassed problem.
Wayne.
