I have to agree with Miniflyer.
Has anyone ever taken on of these hand balanced (static) turbines and then run it on a normal balancer? For the life of me I cannot imagine the balance would be that close.
From what I have seen, you can take a perfectly balanced motor, take the compressor off then put it back on and you will blow the balance.
Don't the 44 sized motors have to be factory balanced?
Hi Matt,
You wouldn't think so but it does work ! I have a lot of hours on a hand balanced Wren and it runs great. That was before the compressors came pre balanced so it's even better now. The tolerances have been tightened up as well to make the fit between the shaft and the compressor more exact.
You are correct that the 44 is factory balanced but Hal has the 54.
