Hello
I have not flown with the tray version yet (I have a customer ordered that version and I will for sure be using it) But I did try Richard's own Core tray at the JetCat 20th meeting last year and it felt balanced and comfortable. The customer I mention has a Jeti tray DC 16 and I fly with that, I think the smaller Core will be easier to operate functions on, the Core is also a thin Tx, so switch access is good.
