What servos are everyone using? Apart from the old usual JR and Futaba mentioned on the threads here.

I know that flash comes with 20mm wide servo slots, will 15mm wide servos do the job? i guess ill have to add spacers?
Can someone share servo install photos of the wing or tail.

Came across these KST HV servos that look like great options.
KST 115 2212 - 40.5mm*15mm*34mm / 25kg torque at 8.4 v / 53g
A20-3813 - 40.5mm*20mm*38mm / 48kg at 8.4v (Overkill?) / 72g
