T-Rex 600 flybarless conversion (Outrage): How low is too low?

Hello,

I'm converting a T-Rex 600 NSP with the Outrage .50 flybarless head. Now the blades sit at least 1 cm lower than with the stock head. Possibly even 2 cm, if I keep the default linkage lengths and use the upper hole for the jesus bolt.

The question is, when do I risk a boomstrike?
- The stock head is supposed to work with cheap 620 woodies and soft dampers.
- I use rather stiff 600 CF blades and hard dampers

I converted my Swift 16 and 550 to flybarless with the 3DX head and Sk360 system. Before I had the 3DX head, I converted the stock head and drilled into the head block for extra main shaft clearance, which allowed me to use the the uppermost hole (previously used to capture the flybar bearings) for the J-bolt. This lowered the head about 2cm lower than stock and I had no problems.

Thanks. In the meantime, I decided to simply go for it and try.
Now I have flown two tanks, no boomstrike so far (knock on wood).
