Does anyone Dail-Indicate Heli's without fan/clutch collets?

[blue_collar2]

I fly mostly Kyosho heli's, which lack a collet for minimizing run-out of the engine / fan assembly. I now have a dial indicator and am planing to try and have smoother heli's.

I was planning to try different combinations of engines and spare parts to minimize run-out. Any thing else I can do?

Any tips appreciated!
