From what I recall, this is what the team did to get the High rotor to work at Snowbirds and MHIC. I would probably start around 87-90mm rollout with 38-40 timing. Please be sure to check temps often your first few runs & just keep an eye on your laptimes through the full 8 minutes.
Please feel free to share what you find when you test!
Thanks for the info. The S High is all that appears legal under BRCA rules in the UK. I think the default timing is 47. If you can please explain the relationship between timing and gearing with different rotors, trying to understand what happens with the variables. Many thanks.
