First thing, get a fiberglass cowl from Fiberglass specialties... the plastic one in the kit is miserable! your gear sounds good, but I'd recommend using a much much smaller battery (maybe a 700mah Nimh). The TS-53's should be fine, but if they are at all like HS-225's, be careful of stripping the nylon gears. I used metal geared servos for this reason. You may want to consider one for at least the rudder since it will see some knocking around from the tailwheel.
