That's a nice looking "Stick". Is the yellow one pictured one of the HK Big Stick Kits? Is it yours?
As far as "Mods" to the kit, I only ones I think it really needs are;
-Upgrade landing gear (tail wheel not necessary, but really helps on the ground)
-Make wing "Bolt on"
-Move aileron servos 1 "Rib Bay" out.
-Cut some of the bottom sheeting away for ventilation
Any other mods would be pilots preference
Nice building board also, one day I hope to upgrade to a magnetic board.

p.s. Hard to read the scale, but the "up weight" came in at 1Lb. 12oz. with 2200 batt.
