Rotor Tech 620 mains, which tails?

[Rob43]

Thinking of trying a set of the 620's for my Logo 600SX. I was about to select a set of the 610U when I thought of going a touch bigger. I am expecting to fly under 2000 rpm most of the time. I really like it around 1800. Is there experience with the 620's to indicate I should opt for 106mm tails to go with? I would think running less than higher rotor speeds that the 106's would do well. (I've long ago upgraded the tail rotor assembly to the current one, even though the SX is a V1).

I found this post where Johnny says even 650 / 105 works. So you shouldn’t have any issue. You can measure like Dennis explains.

Yepp, RT-106 should be a perfect match.

Thank you both. I knew there wasn't a clearance problem, but was sort of confirming I would l ikely want something more than 95's.
